Abstract:
1. A transmitter for unidirectionally transmitting, to a receiver using a first differential signal, pixel data of an uncompressed image of one screen during an effective video period representing a period from one vertical synchronization signal to the next vertical synchronization signal excluding horizontal blanking intervals and a vertical blanking interval, the transmitter comprising: a signal transmitting unit configured to transmit, to the receiver, a second differential signal representing transmission data different from the pixel data via differential transmission lines formed from a pair consisting of a first signal line and a second signal line; a signal receiving unit connected to the signal transmitting unit, the signal receiving unit receiving a third differential signal transmitted from the receiver via the first signal line and the second signal line; and a subtracting circuit configured to subtract the second differential signal from the signal received by the signal receiving unit.
