Information generation method and device

According to the information generation method and device provided by the embodiment of the invention, the current sub-data is determined from the audio and video data set based on the arrangement sequence of the at least one sub-data in the audio and video data set corresponding to the target audio and video file, and then the current sub-data is generated based on the target audio and video file. The method comprises the following steps: acquiring a video playing time length and an audio playing time length corresponding to current sub-data, calculating a time length difference value between the video playing time length and the audio playing time length corresponding to the current sub-data, then acquiring the maximum playing time length of a cache region corresponding to current playing equipment, and finally playing the current sub-data on the basis of the time length difference value and the maximum playing time length of the cache region. And generating interleaving result information corresponding to
