Abstract
An audio-video processing method is adapted to an audio-video device and a storage device for processing an index-based audio-video file. The method for processing audio-video data includes a write procedure, a play procedure, and/or a repair procedure. In the write procedure, audio-video data is captured by the audio-video device first, and the audio-video data includes a plurality of continuous samples; a header is written according to the audio-video data; a predetermined number of samples are captured as a data chunk; a prefix index corresponding to the data chunk and the data chunk are written in sequence repeatedly according to the audio-video data; and a file index is written finally. In the play procedure, after the header is read, corresponding prefix index and data chunk are repeatedly read and played. Moreover, in the repair procedure, incompletely written file index and data chunk are repaired through all the prefix indexes.
