DATA TRANSMISSION SYSTEM, TRANSMITTER, RECEIVER, DATA TRANSMISSION METHOD, PROGRAMME AND CABLE FOR TRANSMITTING DATA Russian patent published in 2011 - IPC H04N7/173 

FIELD: information technology.

SUBSTANCE: when an HDMI (R) source performs bidirectional PI data with an HDMI (R) user (72) using an UBE 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), and during bidirectional data transmission using the UBE line (84) only, the switching control module (121) controls the switch (133) such that the UBE signal coming from the HDMI (R) source (71) or the receiver (82) is selected.

EFFECT: high-speed bidirectional data transmission while maintaining compatibility.
