Abstract
An object of the present invention is to provide a sending device, a receiving device, and a sending/receiving device which make it possible to easily implement a two-channel compressed moving picture transmission system by using an existing single-channel compressed moving picture transmission system. The sending device includes transmission systems corresponding to two channels including video bit rate reduction encoders and for compressing picture data, and SDDI encoders and for generating predetermined serial signal data from compressed picture data, and a data selector for conducting changeover between serial signal data of channel output from the transmission system of the channel and serial signal data of channel output from the transmission system of the channel on the basis of a reference frame signal RF.
