Abstract

The invention relates to a parallel signal processing method and system based on video image recognition. The method comprises the following steps: receiving an audio to be played and a video to be played; target feature recognition is carried out on the video to be played, target features are marked, and a marked frame is determined; placing a playing starting point of the to-be-played audio at the mark frame; and when the audio is played, playing the video at the mark frame. According to the embodiment of the invention, target feature recognition is carried out on the to-be-played video, so that the nodes for voice playing can be effectively controlled according to picture recognition in the video during video playing, the determination of the nodes for voice playing is more accurate, synchronization of video playing and voice playing is realized, and the user experience is improved. The situation that the voice is delayed during video playing or the voice does not accord with an actual playing picture is reduced, and the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of signal processing, in particular to a method and system for parallel signal processing based on video image recognition. Background technique [0002] With the rapid development of multimedia playback technology, when playing audio and video files, the most common problem is that, in addition to the errors that may occur when the file itself is stored, the unsynchronized image and sound during playback are the most likely to cause the viewer's inconsistency. Yue, as a result, a good audio and video decoding device will become more and more important in the future leisure market. [0003] The patent document with the publication number of CN101212588 discloses a method for synchronously playing a video signal and an audio signal, because the time when the speaker plays one of the audio frames will be earlier than the display module plays the image frame corresponding to the audio frame. There are (...
