Embodiment Construction

[0041] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0042] Such as figure 1 As shown, an approximate video coding (NDVC) system includes an analyzer 1, an encoder 2, an integrator 3, and a decoder 4 connected in sequence. The analyzer 1 is used to detect the approximate relationship between each video and obtain a set of approximate video, and output an index file corresponding to the approximate video; Encoder 2 is used to receive the index file output by the analyzer, and encode and compress the approximate video according to the index file, and output an independent code stream corresponding to each video; The integrator 3 is used ...

Abstract

The invention relates to an approximate video encoding system comprising an analyzer, an encoder, an integrator and a decoder, wherein the analyzer is used for detecting the approximation relation of each video to obtain a group of approximate videos and outputting index files corresponding to the approximate videos; the encoder is connected with the analyzer and is used for receiving the index files output by the analyzer, carrying out encoding and compression on the approximate videos according to the index files, and outputting an independent code stream corresponding to each video; the integrator is connected with the encoder and is used for integrating all the independent code streams to generate a single code stream; the decoder is connected with the integrator and is used for decoding the integrated single code stream. Compared with the prior art, the approximate video encoding system disclosed by the invention has the advantages that the compression efficiency is high, the space consumption of a video database can be effectively reduced and the like.

Description

technical field [0001] The invention relates to the field of video coding, in particular to an approximate video coding system. Background technique [0002] With the rise of the multimedia original interactive system and the popularity of new media such as network multimedia and mobile multimedia, the number of videos on the Internet is showing a massive and explosive growth. Numerous network television stations at home and abroad, such as: China Network Television, CNN, ABC, etc., broadcast video information in different languages ​​around the clock; Users can also access the Internet through portable smart terminal devices (such as: IPhone, IPad, notebook, etc.) to obtain and publish information such as images and videos; the rapid growth of social networks has made tens of thousands of online videos available. for people to watch and share. Massive videos are stored in data servers and transmitted on the Internet. Searching and watching rich video resources through the...
