Patent ID: 8885102

Claim:
A video transmission device comprising: a transmitter configured to transmit, via a communication interface comprising a first transmission channel, a second transmission channel, and a third transmission channel, video data having a 4:1:1 format to a video display device configured to display the video data, wherein 4:1:1 represents a ratio of a sampling frequency of a brightness component, to a sampling frequency of a first color difference component, to a sampling frequency of a second color difference component, the first color difference component and the second color difference component of one pixel in a first horizontal line of a first frame of the video data are allocated and transmitted within two clock cycles of the first transmission channel, brightness components of four pixels in the first horizontal line are allocated and transmitted within two clock cycles of the second transmission channel and the third transmission channel, and the transmitter is configured to transmit the video data to the video display device for all of the pixels of the first horizontal line of the first frame of the video data, and after transmitting the video data for all of the pixels of the first horizontal line, set pixels in a second horizontal line next to the first horizontal line of the first frame of the video data as a target to be transmitted.
