Abstract:
1. A dynamic image receiving apparatus for selecting and receiving dynamic image streams coded by a picture unit based on intra-frame coding and inter-frame prediction from two or more channels, and collecting representative images of the plurality of channels by decoding the received streams, the apparatus including: a coded stream receiving device for receiving the dynamic image streams from the channels, and extracting time at which a code of an intra-frame coded picture within the streams is received, and decoding time stamp or presentation time stamp added to the intra-frame coded picture; an accumulative processing device for storing receiving time of the code, the decoding time stamp or the presentation time stamp as time information by being related to the respective channel; and a time predicting/channel selecting device for predicting receiving time of codes of intra-frame coded pictures to be received from current time and thereafter for each of the plurality of channels based on a history of the receiving time of the codes of the intra-frame coded pictures and the decoding time stamp or the presentation time stamp stored in the past, and determining the channel to be received based on an obtained predicted result, wherein the time predicting/channel selecting device: wherein the time predicting/channel selecting device allots, to a channel whose difference between the current time and receiving time of the representative image that is collected just before is less than a threshold value, a lower priority order than a channel whose difference between the receiving time of the representative image collected just before and the current time is equal to or larger than the threshold value.
