Abstract

The invention relates to a long-distance nondestructive fiber transmission device of a high-definition multimedia interface (HDMI), which consists of a transmitting module, a receiving module and five fibers. The transmitting module is connected with the receiving module through the five fibers, the transmitting module is connected with a display source by cables, and the receiving module is connected with a display terminal by cables, wherein three fibers transmit a high-speed video / audio signal of a transition minimized differential signaling (TMDS), one fiber transmits a clock signal and one fiber transmits a DDC control signal. In the invention, the realization principle is as follows: four paths of optical signals transmit a high-definition signal, one path of optical signal transmits a display data channel signal read from the display terminal, and transmits back to the display source terminal, thereby completely replacing the copper cables in the cables with five fibers. The HDMI of the invention is transmitted by the five fibers, and has the advantages of high bandwidth, longer transmission distance, low cost and the like.

Description

technical field

[0001] The invention relates to a high-definition multimedia connection cable in consumer electronics, in particular to a high-definition multimedia interface (HDMI) long-distance lossless optical fiber transmission device. Background technique

[0002] HDMI (High-Definition Multimedia Interface), also known as high-definition multimedia interface, is the first to support transmission on a single cable, uncompressed full digital high-definition, multi-channel audio and intelligent format and control command data digital interface. The HDMI interface was initiated by Silicon Image and jointly developed by a working group jointly established by eight well-known consumer electronics manufacturers including Sony, Hitachi, Panasonic, Philips, Thomson, and Toshiba. The current highest version is the HDMI1.3 specification released in June this year. HDMI can not only meet the current highest resolution of 1080P, but also support the most advanced digital audio for...
