Abstract

The invention provides a soft decoding verification model platform which comprises a video source storage device, an analog-digital conversion module, a coding module, a compression module and a soft decoding module which are sequentially connected. An image and video capturing device serves as a video source to be input and stored in the video source storage device, video source data on which analog-digital conversion is carried out are sent to the coding module, after the coding module is used for coding the video source data, the coded video source data are transmitted to the soft decoding module to be decoded and displayed and output in real time through a UDP protocol channel after being compressed through the compression module. According to the soft decoding verification model platform, under the premise that the video quality is not lost, the video transmission efficiency is greatly improved, and the requirement for narrow-band transmission of high-definition videos is met.

Description

technical field [0001] The invention relates to a model platform, in particular to a soft decoding verification model platform. Background technique [0002] With the continuous development of multimedia communication with video as the core, video applications are gradually developing towards higher definition and higher quality. At the same time, the continuous emergence of a large number of digital video compression algorithms requires higher and higher efficiency of video transmission and storage. Therefore, there is still an urgent need to further improve video compression coding efficiency, and the limitations of the currently widely used H.264 video compression standard are becoming increasingly apparent. Contents of the invention [0003] Aiming at the defects in the prior art, the purpose of the present invention is to provide a soft decoding verification model platform, which can greatly improve video transmission efficiency without losing video quality, and meet ...
