DATA TRANSMISSION SYSTEM, TRANSMITTER, RECEIVER, DATA TRANSMISSION METHOD, PROGRAM AND CABLE FOR TRANSMITTING DATA Russian patent published in 2012 - IPC H04N7/173 

FIELD: information technology.

SUBSTANCE: when a High Definition Multimedia Interface (HDMI) (R) source (71) performs bidirectional transmission of Internet Protocol (IP) data with an HDMI (R) user (72) using a consumer electronics control (CEC) line (84) and a signal line (141), a switching control module (121) controls the switch (133) so that when data are transmitted, the switch (133) selects the component of the signal which forms a differential signal which is output from a conversion module (131), and when data are transmitted, the switch (133) selects the component of the signal which forms the differential signal output from the receiver (82). During bidirectional data transmission using the CEC line (84) only, the switching control module (121) controls the switch (133) such that the CEC signal coming from the HDMI (R) source (71) or the receiver (82) is selected.

EFFECT: providing a high-speed bidirectional data transmission interface, which is compatible with a data transmission interface which enables one-way transmission of pixel data of uncompressed images with high speed.
