Abstract:
To provide a dynamic image receiving apparatus which receives dynamic image streams coded with inter-frame prediction such as MPEG from a plurality of channels, and collects the dynamic image streams containing intra-frame coded pictures from each channel in a short time. The dynamic image receiving apparatus includes: a time information accumulative processing device which accumulates code receiving time of the intra-frame coded picture of the dynamic image stream, and periodicity time information containing one of or both of presentation time information and decoding time information contained in the dynamic image stream for each dynamic image stream of the plurality of channels; code receiving time predicting devices which predict the code receiving time of the intra-frame coded pictures based on the periodicity time information; and a channel selection control device which controls channel selection of the dynamic image stream to be received based on the predicted code receiving time information.
