Abstract:
1. A video information reproduction method for receiving content formed by a sequence including at least intra-frame encoded image information and inter-frame forward prediction encoded image information, and including time stamp information, from a content server connected by a network or from storage media, at a plurality of video information reproducing devices and decoding and reproducing the content at the video information reproducing devices, the video information reproduction method comprising: selecting a video information reproducing device from among the plurality of video information reproducing devices as a reproduction time reference and detecting a reproduction time difference between each of the video information reproducing devices and the reference video information reproducing device; and for at least one of the video information reproducing devices, adjusting a number of frames to be reproduced such that: wherein a prescribed number of frames of duplicative or dummy image information are inserted in a predetermined location of the sequence to be distributed or read from the storage media, wherein the reference video information reproducing device is configured to reproduce a certain number of the frames of duplicative or dummy image information from reproduction, the certain number being less than the prescribed number, and wherein, for the at least one video information reproducing device, the number of frames of encoded content to be reproduced is increased or decreased relative to the number of frames to be reproduced by the reference video information reproducing device by causing the at least one video information reproducing device to reproduce a smaller or larger number of the frames of duplicative or dummy image information than the certain number.
