Patent ID: 7706691

Claim:
A transmission device having optical fiber high definition digital audio-video data interface (HDMI/DVI/UDI) for transmitting the data of a plurality of logic channels of high definition digital audio-video data interface, and transmitting and receiving the data of a display data channel and of a customer electronics control channel of high definition digital audio-video data interface through at least an optical fiber, the transmission device having optical fiber high definition digital audio-video data interface comprising: a light transmission unit for converting the data of the plurality of logic channels into light signals, and transmit them into the optical fiber for transmission; and a first display data channel transmission module for DC-balancing the data of the display data channel and the customer electronics control channel, serializing the data and convert them into light signals, and then transmitting them into the optical fiber for transmission, converting the received light signals into electric signals, de-serializing, de-DC-balancing, and then transmitting them to the display data channel and the customer electronics control channel, wherein the first display data channel transmission module comprises: a plurality of first reverse units for reversing the data of the display data channel and the customer electronics control channel into a first reverse data; a first serial unit for serializing and outputting the first reverse data, a first un-reversed data of the display data channel and the customer electronics control channel as a first serial data; a first light transmission/reception unit for transmitting the first serial data and receiving a second serial data; and a first de-serial unit for de-serializing the second serial data.
