Patent ID: 8237773

Claim:
A communication system, comprising: a sending apparatus configured to transmit a Digital Visual Interface signal wherein pixel data formed from color data including red data, green data and blue data are disposed successively for the individually same color data through a Digital Visual Interface cable; and a receiving apparatus configured to receive the Digital Visual Interface signal transmitted from said sending apparatus through said Digital Visual Interface cable, said sending apparatus being configured to utilize a Dual Link mode to transmit color data of 8 bits from within each of the pixel data formed from color data of 8+N bits to said receiving apparatus through a first transmission path of said Digital Visual Interface cable, N being an integral value equal to or greater than 1 but equal to or smaller than 8, and to transmit color data of the remaining N bits from within each of the pixel data to said receiving apparatus through a second transmission path of said Digital Visual Interface cable, said sending apparatus including a multiplexer configured to separate the color data of 8+N bits which form the pixel data into the color data of 8 bits and the color data of N bits, to place, after separation, the color data of 8 bits into first data of 8 bits which are effective at a rising edge of a dot clock while placing the color data of N bits into second data of 8 bits which are effective at a falling edge of the dot clock, to multiplex the first data and the second data, and to output multiplexed data obtained by multiplexing for each of the color data of 8 bits and the color data of N bits, and said receiving apparatus being configured to receive the color data of 8 bits and the color data of N bits through said first transmission path and said second transmission path, respectively, and to synthesize the color data of 8 bits and the color data of N bits to restore the pixel data.
