<P>PROBLEM TO BE SOLVED: To enable transmission and reception of a large amount of data while keeping the real-time property at a frame level without continuous occurrence of frame transmission delay even if the frame transmission delay temporally occurs due to various kinds of processing delays. <P>SOLUTION: A broadcast material reproduction device include: a switch part for switching a plurality of input/output channels; a transmission-side signal processing part connected with respective input channels of the switch part, for storing material data of a broadcast program in a recording medium; a reception-side signal processing part connected with respective output channels of the switch part, for receiving the material data transmitted from the transmission-side signal processing part; transmission means for transmitting the material data stored in the recording medium to the switch part with transmission timing different for each channel; and control means for, when the material data is not transmittable with timing when the material data has to be transmitted by the transmission means, transmitting the un-transmittable material data to the switch part with the next transmission timing by a transmission method different from the transmission method by the transmission means. <P>COPYRIGHT: (C)2012,JPO&INPIT |
