TRANSMISSION DEVICE, TRANSMISSION METHOD, REPRODUCTION DEVICE, REPRODUCTION METHOD, PROGRAM, AND RECORDING MEDIUM

摘要

A transmission device generates and outputs transmission data obtained by concatenating attribute information including frame rate information and frame identification information on the frame contained in the reference frame period to main data indicating video and/or audio. When reproducing the main data by using this transmission data, the reproduction speed variable range is set according to the frame rate information. According to the reproduction speed indicated within the reproduction speed variable range, thinning and repetition of the video and audio data are performed by utilizing the frame identification information, thereby facilitating variation of the main data reproduction speed and generating a video signal and an audio signal.
