SENDING DEVICE, RECEIVING DEVICE, SENDING-RECEIVING DEVICE, TRANSMITTER, AND TRANSMITTING METHOD

摘要

A sending device, receiving device, and sending-receiving device which can easily realize a two-channel compressed animation transmitting system by using already existing one-channel compressed animation transmitting systems. The sending device is provided with sending systems for two channels respectively having video bit rate reduction encoders (2 and 6) which compress picture data and SDDI encoders (4 and 8) which generate prescribed serial signal data from compressed picture data, and a data selector (9) which switches serial signal data for channel (1) outputted from the sending system for channel (1) and serial signal data for channel (2) outputted from the sending system for channel (2) to each other based on a reference frame signal Rf.
