Problems solved by technology

[0003] Due to the large amount of data transmitted by the video, even under the wired network, the video transmission effect is not very ideal
However, due to the limited bandwidth capability of the wireless network, compared with the wired network, the bandwidth of the wireless network is low and the stability is poor. Therefore, how to improve the fluency of video playback as much as possible under the condition of limited network bandwidth has become a great challenge for wireless video technology.

Embodiment 1

[0034] figure 2 It is a flowchart of a video transmission method provided by Embodiment 1 of the present invention. The execution subject of this embodiment is a video server, such as figure 2 As shown, the video transmission method of this embodiment includes:

[0035] Step 201: Receive a video request message from a mobile terminal, where the video request message includes terminal information and wireless field strength information;

[0036] Specifically, the mobile terminal initiates a video request message to the video server. The video request message indicates that a client wants to watch a certain video. Therefore, the video request message carries terminal information that can identify the client and the video information to be watched. Generally, terminal information includes information such as the identification of the mobile terminal, the screen resolution of the mobile terminal, the encoding format supported by the mobile terminal, and other hardware capabilities. ...

Embodiment 2

[0046] image 3 This is a flowchart of the video transmission method provided in the second embodiment of the present invention. This embodiment can be implemented based on the first embodiment, and the similarities will not be repeated, such as image 3 As shown, the method of this embodiment includes:

[0047] Step 301: Receive a video request message from a mobile terminal, where the video request message includes terminal information and wireless field strength information;

[0048] Step 302: Map the terminal information to the first collection parameter of the video collection terminal according to the first parameter mapping table stored in advance;

[0049] Specifically, a first parameter mapping table is pre-stored on the video server, and the corresponding relationship between the information of the mobile terminal and the video stream information corresponding to the video capture terminal is stored in the first parameter mapping table, for example, the mobile terminal supp...

[0058] Figure 4 This is a flowchart of a video transmission method provided in Embodiment 3 of the present invention. This embodiment can be implemented based on Embodiment 1, such as Figure 4 As shown, the method of this embodiment includes:

[0059] Step 401: Receive a video request message from a mobile terminal, where the video request message includes terminal information and wireless field strength information;

[0060] Step 402: Map the terminal information and the wireless field strength information to the second collection parameter of the video collection terminal according to the pre-stored second parameter mapping table;

[0061] Specifically, a second parameter mapping table is pre-stored on the video server, and the mobile terminal information, the correspondence relationship between the wireless field strength information and the video stream information corresponding to the video capture terminal are stored in the second parameter mapping table. For example, the ma...

Abstract

The invention provides a video transmission method and system as well as a video server. The method comprises the following steps of: receiving a video request message from a mobile terminal, wherein the video request message includes terminal information and wireless filed strength information; acquiring a first video code stream matched with the terminal information according to the video request message; compressing the first video code stream according to the wireless filed strength information to acquire a second video code stream; and sending the second video code stream to the mobile terminal. In the technical scheme of the invention, the sizes of the video code streams are further optimized on the basis of wireless field strength, the occupation of wireless bandwidth by the superfluous video codes stream in the moving process of the mobile terminal is reduced, and the smoothness for playing a video in the mobile terminal is enhanced through reducing the sizes of the transmitted video code streams.

Description

Technical field [0001] The present invention relates to communication technology, in particular to a video transmission method, system and video server. Background technique [0002] With the development of Internet technology and the popularization of mobile communication terminals, mobile Internet has gained greater development space and market, and wireless video technology has received unprecedented development opportunities. Wireless video technology refers to the technology in which mobile terminals receive video streams through wireless networks. At present, wireless video transmission is usually carried out by the video service platform according to the hardware type of the mobile terminal, correspondingly encoding and compressing the video code stream collected by the video collecting terminal and transmitting it to the mobile terminal through the wireless network. [0003] Due to the large amount of data transmitted by video, the effect of video transmission is not ideal...
