This situation leads to the loss of the 5-second Chinese audio stream and the 5-second English audio stream while the video stream is playing normally. In this case, the digital TV terminal cannot play the 5-second audio stream. The Chinese audio code stream or the audio corresponding to the English audio code stream with a duration of 5 seconds, the digital TV terminal will mute for 5 seconds during playback, which causes the audio and video to be out of sync

The invention relates to the technical field of digital televisions, and especially relates to a recorded audio and video playing method and device, and a storage medium. The method comprises the following steps: reading stored files of recorded audios and videos; dividing the files of the recoded audios and videos into a plurality of data packets including the recording time; in the process of orderly injecting the data packets into a demultiplexing module, determining the number of the data packets injected into the demultiplexing module within a preset injection time length, and the recording time length of recording the data packets; if the recording time length is greater than the preset injection time length, then pausing the process of orderly injecting the data packets into the demultiplexing module for a target time length; and playing the recorded audios and videos according to the data packets injected into the into the demultiplexing module. Therefore, when the audios are switched, the amount of data of the cleared audios can be reduced, so that the situation that the audios and videos are not synchronized when a digital television terminal is played can be improved.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of digital television, and in particular to a method, device and storage medium for playing recorded audio and video. Background technique [0002] With the development of digital TV, the functions of digital TV terminals are becoming more and more powerful. Among them, the function of a personal video recorder (PersoNal Video Recorded, PVR) has gradually become a mainstream application in broadcasting and television services. In the prior art, the digital TV terminal completes the recording process after receiving the encrypted audio and video code stream and related authorization control information (ENtitlemeNt CoNtrol Message, ECM) sent by the digital broadcasting TV network and storing them in the storage device, so that the user It can be played when looking back. [0003] During the playing process, the audio and video code stream is divided into video code stream and audio cod...
