Embodiment 1

[0026] A method for reviewing video material with a low bit rate, comprising the following steps:

[0027] (1) Producing low-bit-rate material of the original video material, the code-stream of the low-bit-rate material is lower than that of the original material;

[0028] In this embodiment, the proxy material is generated during the process of uploading the original video material to the video server. Proxy material has the same information except that the bit rate is lower than the original material, such as the playback length of the material and the number of frames per second. Therefore, reviewing the proxy material is equivalent to reviewing the original material. For the generated low-bit-rate materials, different bit-streams can be selected according to the situation, and multiple bit-streams can also be generated at the same time. In this embodiment, one original material generates three code streams, which are 1M / s, 512k / s, and 50k / s respectively. When generating ...

Embodiment 2

[0039] The difference from Embodiment 1 is that in step (1), five low-bit-rate materials are generated, which are 4M / s, 2M / s 512k / s, 384k / s, and 50k / s;

[0040] In step (2), the generated proxy material is stored in the video server;

[0041] Among them, the low-bit rate material with a code rate of 512k / s and 384k / s can be used for on-demand and download of Internet TV, and the low-bit rate material with a code rate of 50k / s can be used for mobile TV.

[0042] It can be seen from the above embodiments that when using the method of the present invention to review video materials, it does not need to occupy expensive decoding channels, thus greatly reducing production costs. In addition, distributed viewing is not limited by location and time, and greatly improves the viewing efficiency of video materials; at the same time, in addition to being used for viewing, low-bit-rate video materials can also provide Internet TV and mobile TV It is used in trade with programs without ad...

Abstract

In currently used technology, the program materials played by TV station is saved in the video server; a server can only provide several decoding channels for use in playing; a watching for granting a license to the program materials needs to occupy an independent decoding channel, and one program material usually needs to be examined by several government departments for granting the license. By using the invention, in the process of uploading the program material to the video server, the program material with low bit-stream will be generated to provide a licensing watching for the relevant departments in a distributing LAN.

Description

technical field [0001] The invention belongs to the technical field of radio and television broadcast control systems, and in particular relates to a method for reviewing video material with a low code rate. Background technique [0002] In the broadcasting and television system, whether the broadcast content is legal is a very critical issue. This problem involves the review of the material. Only the legal material after review can be used for broadcast. The so-called review is to play the material once to check whether there is any illegal content in the material, such as illegal content itself, whether there is any problem in the production process, whether there is a mosaic when uploading, etc. Usually, the broadcast control system stores the material in a professional video server, and uses the expensive video server decoding channel to play. Considering the cost of the system, the TV station generally only arranges 1 or 2 decoding channels for viewing, which wastes ex...
