Timestamp-based audio and video processing method and system thereof

摘要

A timestamp-based audio and video processing method and a system thereof are provided. The method is adapted to an electronic device having an image capturing device and an audio input device and includes the following steps. First, an image signal and an audio signal are extracted within a same time interval by respectively using the image capturing device and the audio input device so as to generate video data and audio data, and the time interval is converted to timestamp data, where the video data includes a single video frame with a variable file size, the audio data includes multiple audio files with a fixed file size. Next, the video data, the audio data, and the timestamp data are integrated into transmission data.

1. A timestamp-based audio and video processing method, adapted to an image capturing device and an audio receiving device, comprising:
obtaining first transmission data from a first source and obtaining second transmission data from a second source, wherein the first transmission data is an audio-video packet comprising first video data, first audio data, and first timestamp data, wherein the first video data comprises a single video frame with a variable file size, wherein the first audio data comprises a plurality of audio files with a fixed file size, wherein the second transmission data is a second audio-video packet comprising second video data, second audio data, and second timestamp data, wherein the second video data comprises a single video frame with a variable file size, wherein the second audio data comprises a plurality of audio files with a fixed file size, and wherein the electronic device comprises a first data buffer having a plurality of first temporary positions and a second data buffer having a plurality of second temporary positions; pushing the first audio-video packet to the first temporary positions sequentially according to the first timestamp data in the first audio-video packet and pushing the second audio-video packet to the second temporary positions sequentially according to the second timestamp data in the second audio-video packet; and when the first audio-video packet is sorted at first among the first temporary positions and when the second audio-video packet is sorted at first among the second temporary positions, concurrently playing the first video data and the first audio data in the first audio-video packet as well as the second video data and the second audio data in the second audio-video packet respectively by using the screen and the audio playing device according to the first timestamp data of the first transmission data and the second timestamp data of the second transmission data.
