Into the mobile world

Analysis: Zhao Hang

Now the rapid development of Internet technology and new things keep emerging, such as we had to listen to music only slowly download the MP3, the same turtle crawling pace of your patience, but a test. Well now, the network speed is faster, more network providers to support online streaming format media player agreement, enjoy online music sites and video on demand sites springing up, we do not have to wait until the entire file and then play all the downloaded it, but while downloading files, listen to one side only need to download before playing some of the contents of the file, the contents stored in the buffer, so there is some delay in the beginning, some of the remaining files will appreciate the program in your When the background from the server to download and save a lot of download time, and today we give tell you about the most common audio format for streaming media and related technology.

First, the definition of streaming media transmission

Streaming refers to the network using streaming technology, continuous time-base media, through the network transmission of audio, video or multimedia files. The so-called streaming technology, is now mainly refers to the network transmission media (such as video, audio) technology general, their specific meaning through a network of video and audio transmission to the PC. Achieve streaming are two methods: real-time streaming mode (Realtime streaming) and order of streaming mode (Progressive streaming).

Second, a common format for streaming audio

Now the network is a common audio format for streaming media are mainly the United States Realnetworks Inc. *. RA *. WMA formats and Microsoft's format, in addition to more than one professional in the field for the U.S. Apple *. MOV format, in three format, MOV format is the best sound quality, especially in MIDI, the support of GS and GM two tone playback to be significantly stronger than that of Windows Media Player, below we give details of the characteristics of these types of formats.

1, RealAudio format

RealNetworks Inc. is a U.S. veteran-class products, is currently the most popular online streaming media technology. Many Internet, music, video on demand sites are using it. RealMedia includes RealAudio (audio files), RealVideo (video files) and RealFlash (vector animation) these three files.

2, QuickTime format

As QuickTime and RealMedia, finished joint compatible with Mac and PC. Speeds and file sizes in the same circumstances, it is the best video quality. It is composed of three different parts: QuickTime Movie (movie) file format, QuickTime Media Abstraction Layer, QuickTime built-in media services system.

3, Windows Media Audio format

WMA (Windows Media Audio) is Microsoft's heavyweight players from its predecessor, Microsoft's Netshow, back strong, but also a large number of the most familiar to Windows users, its core technology is the ASF (Advanced Streaming Format, Advanced Stream format). ASF format support any compression / decompression coding, and can use any of the underlying network transmission protocol, with great flexibility, Bijiao compression standards like MPEG to increase the function of control command script, it is to reduce data traffic However, to maintain quality of the documents used to realize streaming multimedia content distribution.

4, Flash format

Flash is popular on the network although the vector animation, but it sounds like can contain information, also supports streaming, high-quality Flash SWF format is more superior sound and file size smaller, but now they have to use this technology to do music site, you need to enjoy the time to install a Flash plugin to present speed of the network, the few hundred KB of Flash plug-in can be a little too much installed, then you can enjoy the music of the SWF format .

Third, streaming media transport protocol

In the browser, we often address is http:// and ftp:// beginning. Web servers can handle streaming media files http protocol, but the design of Web server itself can not efficiently transmit streaming media files. Streaming media packets must occupy an uninterrupted stream, and will long remain with the server connection status, if there are too many visitors at the same time on-line viewing, performance will be significantly reduced. To solve this problem, streaming media file has its own set of protocols.

1. Live streaming protocol (Real Time Streaming Protocol, RTSP), which is to help build a RealNetworks company used to send streaming media, open web standards. Although it must use a special server known as RealServer, however RTSP video streaming media to enhance the quality, improve transmission efficiency and provide better high-volume processing. If your ISP (Internet information service providers) have a RealServer services, it is recommended that you use RealServer instead of using the Web server to send streaming media files.

2.MMS (Media Server Protocol, MMS), which is a Microsoft-defined protocol for streaming media.

3. Real-time Transport Protocol (Theater Server Protocol, RTP), which is the Internet, a multimedia data stream protocol. RTP is defined as the transmission in-one or one to many work situations, the purpose is to provide time information and achieve synchronous flow, simple language that is on the network Web server,

4. Resource Reservation Protocol (Resource Reserve Protocol, RSVP), as audio and video data streams than traditional data networks are more sensitive to delay, to the network transmission of high-quality audio, video information, in addition to bandwidth requirements but also need many more conditions. RSVP is being developed by Internet on the Resource Reservation Protocol, RSVP set aside to use as part of the network resources (ie bandwidth).

These agreements replace the http and ftp, but like mms: / / 61.139.25. 41/quake such as beginning with MMS or RTSP.

Fourth, a variety of formats player

All three formats each have their own players, they are RealPlayer, QuickTime Player and Windows Media Player.

1.RealPlayer

Real format of high compression ratio and good compression and transmission capacity, especially suitable for network broadcast, or online broadcast mode, the video streaming media format, RM format is the worst quality, but the file is the smallest, low-speed network users ( non-ADSL and broadband users) can also enjoy online videos. Player of the installation process there is a network wizard, allowing users to the actual situation in the network choose their routes. RealPlayer player is also very easy to use, the system of resource consumption in the other two, is the best choice for low-profile users. With ReaNetworks's outstanding technology, it has occupied more than half of online streaming video and audio on-demand market.

2.QuickTime Player

QuickTime Player can be provided through the Internet real-time digital information flow, workflow and document playback. High quality QuickTime file, file tall disadvantage is relatively large, of course, high-definition, high-quality images often means larger files, more transmission time. For this reason, the network can only use QuickTime to do some multi-media advertising, product demonstrations, high-definition video, that require the performance of high-definition video programming on the screen. Network speed is not fluent in the local watch up some difficult, but the system resources QuickTime Player high for your machine configuration is better to be competent, the best is to have fast CPU and more memory, high-performance computers.

Note, QuickTime Player player is not free, and we can go to Apple's home page to download trial version, download address: www.apple.com / QuickTime / download. Tens of dollars and need to register before you can use.

3.Windows Media Player

WMA players to use Windows built-in Windows Media Player on it, WMA music format, a major feature does not require extra player, you are in the "Start / Programs / Accessories / Entertainment" in the figure can find it. Its production, publishing and playback software also integrates with Windows NT/2000/9X. Windows Media Player is the addition of stronger copyright protection, to limit play time, play a certain number of restrictions and even the operating system, etc. This was preventing the terrible fix the audio and video piracy, but a great boon for publishers. Windows Media Player files bigger than the RealMedia file, state line than the QuickTime player can get faster, smoother results.

5, the production of streaming audio files

Now commonly used in audio editing software to support the sound file formats into streaming media format, such as we often use the audio production tools Cooledit Pro and Sound Forge's "Save as" (Save selected items) can be found in streaming media format figure, as in Cooledit Pro's "Save" option.

As long as we work area in Cooledit Pro Select all of the sound file, in the "File" menu, select "Save As" option, the option a lot of sound files for various rate conditions, very easy, just select the appropriate The rate can be the WAV, MP3 sound files so common streaming media formats into a sound file.

Unfortunately Cooledit Pro only supports the G2 RealNetworks and Realmedia, do not support Microsoft's WMA format and require plug-ins to convert WMA. Now the network's WMA format music files have been more and more, more and more popular, and so very convenient, how should we do?

We take a look at another powerful audio editing and processing software from Macromedia Inc. in the United States Sound Forge, I believe we have a hell knew the name of it. Similarly, we have Sound Forge's "Save As" choose items where the RA can be seen Realmedia format, more than a WMA Cooledit Pro option.

We see in Samplitude's diverse output options can be called in to support more audio formats, we can easily bring the original sound file into a streaming media format needs. Need to remind you, Samplitude system resources occupancy rate is relatively high, low-profile friends, please use caution.

The birth of Kissing fish

FreeBSD Serial (64): NetBIOS name resolution

In the development of personal computers and local area network early, in order to achieve network capacity of personal computers, Microsoft and IBM co-developed a protocol NetBIOS, which is a call interface for network communications, IBM developers as they consider this agreement BIOS designed as a basic computer network access interface, the use of the NetBIOS name. The NetBIOS interface development on the use of Microsoft Web servers and corresponding client software.

And IBM Token Ring and Ethernet on the direct implementation of the NetBIOS driver realized the NetBIOS and the physical network layer in between the specific interface, these programs follow the standards known as NetBEUI. NetBEUI direct control of the Token Ring and Ethernet drivers, so it can only run in the local area network. However, the lower NetBIOS itself did not limit the use of the protocol, so it only can run under the NetBEUI support, but also can run in the other protocol support. Other web developers in some other basis of the agreement also achieved NetBIOS interface, such as TCP / IP, IPX and Decnet so. Including the use of NetBIOS over IP TCP / IP protocol, thus the lower the compatibility with the Unix computer, a Unix and PC systems based on communication.

Windows family of computers does not necessarily use IP as its network transport protocol, it can also make use of IPX or NetBEUI protocol, but FreeBSD does not support IPX or NetBEUI on NetBIOS, must configure IP protocol for the Windows clients can share with each other FreeBSD resources.

NetBIOS name resolution

As a matter of fact is a NetBIOS and TCP / IP standards developed independently, although it can use TCP / IP as the transport protocol, but due to the different concept, it does not use TCP / IP to provide the full capacity, but to use their own way to accomplish similar work. The biggest difference is the way name resolution, NetBIOS name resolution with its own independent concepts and capabilities, so it uses the name resolution mode on and the TCP / IP in the standard analytical methods 鈹?鈹?DNS different. In the NetBIOS name resolution must be received one named after the corresponding IP address, NetBIOS sessions can be established on the basis of normal TCP connection was. Therefore, NetBIOS, the NetBIOS name resolution is a conversation with ordinary TCP connection biggest difference.

NetBIOS name resolution and DNS name resolution of NetBIOS is the biggest difference is that dynamic, the computer must first register their names before they can resolve to the name. Although dynamic analysis brought great convenience, but more complex and inefficient, so only for small-scale local area network.

Each NetBIOS name can be up to 16 characters, 16 characters Enter the name used to identify the type of procedure used. When the NetBIOS computer to communicate, it must be based on NetBIOS names, not based on IP address. A NetBIOS service program must first register their NetBIOS name, and an application will need to NetBIOS name queries needed. For example, after each Windows computer starts initializing the network configuration when using the computer name used to initialize its NetBIOS name.

NetBIOS name resolution method

From the NetBIOS name to find the corresponding node address (TCP / IP protocol for the IP address) to find several different ways.

Local Radio: send broadcast on the local network, by broadcasting the NetBIOS name of a device, find the corresponding IP address. Broadcast can be used to register their NetBIOS name, such as a computer can broadcast the name of the machine, declared itself to other computers using the NetBIOS name.

Buffer: Each NetBIOS computer support, maintenance of a NetBIOS name and IP address of the corresponding list of the names of all of these correspond to a certain degree of survival in order to update.

NetBIOS name server: use a name server to provide the name and IP resolution between the tasks, the NetBIOS name server known as the NBNS (NetBIOS Name Server), Miscrosoft achieved NBNS name server for the WINS (Windows Internet Name Service). NBN S NetBIOS computer must first register their NetBIOS name, complete name of the registration process.

Predefined file lmhosts: Microsoft Windows through the Find a local file lmhos ts stored in the data, to identify the network name and IP NetBIOS relationship, this approach is not a NetBIOS name recognition of standards, but it is Microsoft's implementation approach, and therefore a kind of de facto standard.

Resolve through DNS and the hosts file: DNS server and the local hosts file, stored data is used for standard TCP / IP protocol used to convert between names and IP the way, but with no other way to find the corresponding node address, Microsft Window s are usually also through the standard TCP / IP name resolution methods, to name and IP conversion. This is not the same NetBIOS standard, but the expansion of Micorsoft.

NetBIOS means of identification from five, and one of the names registered with different methods in conducting the different combinations, different names on the form recognition strategy. In the NetBIOS standard, will identify strategies to use different model names as different NetBIOS node type.

B-node: the way through the broadcast to register and identify NetBIOS names. The IP protocol on the Net BIOS, need to be based on UDP broadcast this way in a small network works well, but when the network increases, will be using a router to a large network is divided into several smaller networks. In general, routers do not forward broadcast data, broadcast packets sent to the local network only. Although you can configure the router to b-node broadcast forwarding UDP broadcasts, but it will produce large amounts of useless network data, and name registration and resolution of the difficulty has increased. Therefore, for larger networks, this approach undesirable.

P-node (peer-to-peer): identification of the name, etc. can provide a very effective method, which uses the NetBIOS name server for name registration and name recognition. So for each NetBIOS computer, you must specify the same NBNS server's IP address. In this way NBNS server is down or change the settings (such as IP addresses, etc.) of the case, name resolution can not be completed, it can not be NetBIOS communication. Of course, the computer can be configured to use NetBIOS over NBNS server to a problem in which the use of backup servers.

M-node (Mixed): In order to properly resolve NetBIOS names, the best combined use of broadcast and the way the name of the server, so the name recognition is a complex process. M-node first by way of B-node broadcasts the name of the recognition process, when the broadcast failed, another way to use P-node query.

H-Node (Hybrid): H-node model is a complex pattern, with M-node difference is to find a different order. H-node first find the NBNS name server, and then use the broadcast query.

Windows in the way of actual use of the name recognition is a standard H-node mode of expansion, Windows family of computers will first check the contents of the cache, and then view the WINS server, after the broadcast, and then find the lmhosts file, and by hosts and DNS lookups. Actual NetBIOS recognition is a complex process, mainly because NetBIOS name resolution is a dynamic way, each computer must register itself.

NetBIOS name of the recognition process

With different DNS, NetBIOS names using dynamic approach to management. DNS data is static, add and remove DNS names require the administrator manually change the configuration file. But the NetBIOS requires a computer on the network automatically register its name, the computer shut down after the occupation of the name will be released, this process does not require administrator intervention. Because it requires additional network data to complete the registration process name, making it unsuitable for large networks such as the Internet. NetBIOS name recognition requires three steps:

Name registration: NetBIOS startup in the computer to occupy the entire network, a NetBIOS name statement, if you have other computers take up the name, the computer will receive an error message. Registration is through the network broadcast a statement to the NetBIOS name server information or to register a way to achieve.

Name Resolution: NetBIOS names by broadcast or query to resolve a NetBIOS name server. In addition, through the lmhosts file and secondary DNS name resolution.

Name deleted: in the system shutdown or provide services to the end of the workstation will remove its occupation of the NetBIOS name.

By NetBIOS name and share name of the directory, we can locate resources on the Windows computer. Microsoft to use U NC to determine the form of a network resource location, a UNC start a double backslash, followed by the provision of resources NetBIOS computer name, then the computer resources of the shared name, the next is the following directory and file name. Such as: \ ntserversharefiles, so use a command of resources:

C:> net use f: \ ntservershare
C:> f:
F:>

Above the net use command will ntserver the share of resources mapped to F: drive.

Name server works

Because b-node broadcast on the network will produce large amounts of information flow, especially in the network is composed of multiple subnets when the router was originally used to isolate broadcast information, but in order for name resolution, you have to forward b- node broadcast packets, which fail to reduce unwanted network traffic purposes.

Using the name server for resolution can avoid this problem, customer inquiries through the pair of name servers instead of broadcasting, information flow would not have spread to every subnet, we can reduce the broadcast data, reduce network of Fudan conserve bandwidth, and effectively improve name resolution speed and accuracy.

Actually existing Windows network or even rarely use the name server for name resolution, which makes these networks there is a big name resolution problems, often there are different neighbor list of different computer networks, the fundamental reason is that broadcast is not guaranteed, it is required to way to resolve the name of the server name resolution problem.

Common NetBIOS computer and NBNS server to communicate with four different communication process:

Name Registration: Each NetBIOS computer starts, all in the name server registration. This automatically updates the database maintained and updated with the dynamic characteristics. Name server will return confirmation message and the name of the survival of TTL. If the customer's name has been taken up, the server will check whether the occupation is still the name of the client on the network to determine whether the name can be used again. This occurred mainly after the crash in the Windows computer to re-register process, because at this point in the computer crashed before it in the name server registered in the name exists, if the name server refused to provide a simple name, then the computer can not re- get their names. Only in true conflict situation, the customer name registration will fail.

Name Update: As each name there is a survival TTL, then when the experienced half of the TTL time, the customer update request to the server, refresh the TTL setting on the server.

Name Release: Customers will communicate with the server shut down the release of its occupation of the NetBIOS name, the name will make the server timeout TTL release the name.

Name Recognition: Customers can send a query to the NBNS name server request for name resolution.

In some cases, clients do not support the name server settings, or use the client software does not support the name server for resolution, you can set up a WINS proxy, which will come in the broadcast data and query the name server to convert, it can help customers Register and respond to customer inquiries broadcasting.

Easily burn miniDVD using NERO 6

Of: ZAZA

How to burn a real miniDVD CDR above had been the topic of heated discussions in various forums, what we say what is true miniDVD.

Before recording the so-called miniDVD popular there are two ways. One is generated rendering MPEG2 format DVD format audio and video files, and then the SVCD in Nero 5 burning functionality into the file to "force" burn. Because Nero will detect the SVCD format video file format is not generated tips, ignore the prompts to complete burn. But such a "miniDVD" is a pseudo-DVD, the actual file format for playback and do not meet specifications. DVD playback quality is not just whether it is high definition, but also the rich features DVD standard DVD menu. DVD menu with the usual VCD, SVCD menu features more fully is heaven and on earth. DVD menu playback multiple video angles, multi-channel voice, multi-subtitle select, hide directory, change the menu, a virtual three-dimensional menu, hide chapters, AC3 5.1 channel, so these are SVCD, VCD menu features catch up. Just how to make a DVD menu you can write a thick book to.

Another approach is to use DVD authoring software DVD format standard direct production of documents, such documents produced have the following characteristics: including the AUDIO_TS, VIDEO_TS directory that, in the VIDEO_TS directory with extension VOB, BUP, IFO's file. This file format produced with exactly the same as the real DVD, including the AC3 5.1 channel, the menu in which such information. As long as the total length of these documents control within the capacity of a CDR, you can burn miniDVD. Burn this real miniDVD can use Nero 5, but the tips are often complicated to set those back with nothing to burn. That success in the CDR burning above the miniDVD is a difficult and lucky thing.



The emergence of Nero 6 so that we can sit back and burn miniDVD. Need to understand the complex set options. Nero 6 is now to see how easy and quick to burn miniDVD of it.

Here demonstrates using Nero Express 6, respectively, and Nero Burning 6 burn miniDVD approach.



Run Nero Express 6, select the menu Video / Picture option to run the following items burn miniDVD guide.



Burning wizard interface shown above, A is that a good pre-set directory structure miniDVD (DVD directory structure is true, is that recording medium is a DVDR only), there are two directories: AUDIO_TS, VIDEO_TS. VIDEO_TS directory which is red, which is to remind us of the DVD program to create directories which should be placed here. C is that the capacity of the miniDVD show, because usually the use of CDR capacity of 640M, 700M, 800M this specification. Therefore the maximum capacity marked as 800M. In the 640M and 700M respectively, marked with yellow lines and red line out volume position. Add a file time to pay attention to whether the data miniDVD CDR hand over your maximum capacity.

First of all, double-click the red VIDEO_TS directory into the directory, and then press the picture above B Office Add File button.



Now ready to add the miniDVD files, find the DVD video files well in advance, into the VIDEO_TS directory. Demonstrated by the completion of the DVD file as shown above. Nero 6 DVD production line can use NeroVision Express 2 to make, also can use the following procedure:

TMPGEnc DVD Author

Sonic Foundry DVD Architect Inc.

Sonic DVDit company

SONIC company REELDVD

ULEAD DVD FACTORY

WINDVD company produced DVD Creater Plus

MediaChance company DVDLAB




[Next]



Select the VIDEO_TS directory of all files, press Add to add to miniDVD directory, and then click Finished to add the end of the process.



Then step back to make wizard interface. See those DVD files on the hard disk has been added to the Nero Express 6 of the miniDVD files directory. Click Next to create miniDVD Nero Express 6 the third interface.



This step interface is miniDVD final preparation before burning, you can choose recorder, set burner burning speed and burning copies. Validation data set is finished burning, I suggest you use this time to select. Burning high-speed recorder, when experience tells us that speed is usually no more than 24X is appropriate. If the recorder is chosen Nero 6 burner built-in virtual image, it will produce a CD-ROM ISO or NRG image file format. Dissemination of this document can be distributed through the network.

All settings are ready, press the Burn button, and recording began.



Often not a long time, Nero Express 6 will tell us burn a miniDVD has been completed. In this way, a miniDVD easy to create. Quickly get the DVD-player a try.

MiniDVD recording completed in some of the DVD player can not play, this is because some DVD players do not support the identification of CDR Media DVD format reasons.

Here to talk about being burned in Nero Burning 6 miniDVD approach.



Nero Burning 6 of the main interface shown in the A Division miniDVD down to find the option to select it with the mouse. New Office and then press B button. Create a miniDVD project.



Nero Burning or previous style, so are the contents of the hard disk documentation project. Find ready miniDVD files, select the Drag to the left after the VIDEO_TS directory. Ready after the button press the A Division of burning. Will pop up Nero Burning 6 of the recording preparation interface.



Burn miniDVD select box in the figure Disc-at-once, and then click the Burn button Burn, Nero Burning 6 start burning miniDVD. After the completion of burn miniDVD arises.

How to turn your career profile?

Elevator with the boss, the boss does not know who I am; I worked day and night overtime work, credit is not bored me ... ... it?

"Show off your own personal responsibility, you have to let people know who you are and what you've done something," Peggy - Klaus (Peggy Klaus) in her latest book, "Chi Chi sell boast" ( Brag) wrote.

How to do this? The following are the recommendations of Klaus:

1. Anywhere, anytime ready.

Taken the first step is very simple boast. 4 things to remind ourselves every day: your name, title, responsible for the task, and the front of the positive work carried out by the affirmative side. These elements on the lips, speak out at any time to prepare.

2. Gathered in the pantry.

Round-table lunch, tea rooms, coffee machine or vending machine next to, as long as a meeting place for improvisation, is to make people understand the importance of your presence. So, not to stay on your desk, get up and move time to time, lunch time, do not resolve on their own desk.

3. Do not rely on numbers to speak.

Do not think the requirements to achieve the above figures like the figure he would say. Everyone wants to learn from others to show them how to overcome obstacles, this is the best tool you boast. So, do not just report the results of your work should be to share your success, and how to overcome difficulties.

4. The use of public awareness of important people on social occasions.

These important people are usually very busy, it is difficult to have the opportunity to meet face to face or have the chance to chat. However, some public social occasions, such as when the company year-end banquet and other grand assembly, that is the golden opportunity of self-promotion.

Baidu Lotte joint venture Formation of landed four domestic B2C

April 22 message, in the intense preparation for more than three months later, the closely watched joint venture Baidu Lotte landing in Tongzhou, Baidu Mr. Xuyang Ren, vice president of joint venture company with people who attend the admission ceremony, a village of Huang.

It also means following Taobao, Suning and other giant, the forces of another large influx of Internet B2C field, the field of four major domestic B2C model also has this shape.

Tongzhou settled in the joint venture model with B2B2C

Co-operation from the beginning to the floor, Baidu Lotte cooperation entered a substantive stage in less than three months.

January 27, Baidu announced Lotte Japan injected 50 million U.S. dollars joint venture company formed and will be available within a year e-commerce site. Of these, Lotte 51% of the shares owned a controlling stake in the joint venture, holds the remaining 49% stake in Baidu.

April 1, Lotte within the company announced the appointment of Akira Nakamura, a joint venture company as Baidu optimistic people, and at the same time as the president of Lotte China Post. Artesyn Technologies exclusively informed, Koichi Nakamura has come to China not long ago, he and Baidu executives were at the admission ceremony for the joint venture - this is Akira Nakamura, a first public appearance in China this weekend, Koichi Nakamura, also rushed to Shenzhen for a B2C Forum.

According to informed sources, Baidu will copy the Lotte Lotte Japan joint venture business model, using B2B2C model. Joint venture charges, there are three main methods: direct charge to the business settled and information services costs, advertising costs and provide value-added services.

Among them, the joint venture company to absorb the informal businesses to enter, to help SMEs to do e-commerce, and to provide information services to receive part of the costs; by merchants on the site location and in the search process to provide auction services in the way of access to advertising; other joint venture Companies can also pay for goods and logistics part of a gain.

It is reported that Japan's Lotte was founded in 1997, is the world's B2C "platform model" of the pioneer and leader, until now, in Japan, has more than 30,000 regular commercial brands and channels to engage in Lotte B2C e-commerce trading platform, now part of the proceeds has been advertising its total revenue accounted for half.

In fact, the joint Baidu is not the first time Japan's Lotte layout in the Chinese market. Back in June 2004, Lotte hoped that through the investment into China's Internet travel market Ctrip, but in holding Ctrip 3 years, Lotte selected a high exit.

Lotte in Japan for the joint, Baidu said looking forward. Mr. Xuyang Ren had said in March this year, B2C e-commerce strategy is the focus of the next Baidu. If all goes well, Baidu Lotte B2C website can be the fastest on the line this year in July.

Four patterns of domestic confrontation between B2C
