Embodiment Construction

[0034] The present invention proposes a system for verifying video coding methods. Compared with the prior art, the system adds an algorithm control module for outputting process control information to the video coding module to be verified and the verified reference Model module, so that these two modules can be divided into n algorithm steps corresponding to each other, and output the algorithm step parameters of each algorithm step; in this way, the comparison module can compare the execution results of each algorithm step separately, and can find out in time question. Furthermore, the system may further include a module for constructing video data with a specific frame-to-frame relationship,

[0035] Correspondingly, the present invention proposes a method for verifying a video encoding method, comprising the following steps:

[0036] A. The video coding method to be verified and the verified reference model are divided into n algorithm steps corresponding to each other i...

Abstract

The invention discloses a system for verifying a video coding method, which comprises a video coding reference model module (204), an algorithm control module (205), a video coding module (206) and a result comparison module (208), wherein the algorithm control module (205) controls the video coding module (206) and the video coding reference model module (204) to output algorithm step parameters by steps; and the result comparison module (208) compares the parameters by steps. The scheme monitors the algorithm by steps, compares and judges by steps, judges each step result in real time and is convenient to debug.

Description

technical field [0001] The invention relates to the technical field of video coding, in particular to a system and method for verifying a video coding method. Background technique [0002] In digital chip design, the verification of logic functions is more and more important. Ensuring the correctness of the logic function design, the accuracy of the algorithm meets the requirements, and the efficient function verification and function debugging are the key links in the digital chip design, and even relate to the progress of the entire project. [0003] At present, the logic function verification method widely used in video codec design is simulation verification method. The video encoding method includes motion vector search, residual calculation, discrete cosine transform (DCT) operation, quantization and encoding. figure 1 Shown is a system block diagram for performing simulation verification on video encoding data in the prior art. A video data segment 101 is intercept...
