PROBLEM TO BE SOLVED: To perform efficient data transmission through an HDMI(R) etc. SOLUTION: An HDMI(R) source 53 decides whether an HDMI(R) sink 61 can receive a sub-signal based upon a VSDB of E-EDID and adds the sub-signal to pixel data of a main image comprising the pixel data less in number of bits than transmission pixel data transmitted by a transmitter 72 when the HDMI(R) sink 61 can receive the sub-signal to constitute transmission pixel data, and a transmitter 72 transmits the data over TMDS channels #0 to #2. Further, the HDMI(R) source 53 transmits a general control packet containing sub-signal information showing whether the sub-signal is included in the transmission pixel data in a control section of a vertical blanking period. The present invention is applicable to, for example, the HDMI(R). COPYRIGHT: (C)2008,JPO&INPIT
