Description

A HDMI photoelectric composite transmission line

technical field

The utility model relates to the technical field of data transmission cables, in particular to an HDMI photoelectric composite transmission line.

Background technique

With the rapid development of multimedia technology, people put forward higher and higher requirements for multimedia transmission quality, especially for high-definition multimedia. The original multimedia transmission of video or audio signals can no longer meet the needs of today's society. HDMI cable is the abbreviation of high-definition multimedia interface cable, which can transmit uncompressed high-definition video and multi-channel audio data with high quality, and the maximum data transmission speed is 5Gbps. At the same time, there is no need to perform digital/analog or analog/digital conversion before signal transmission, which can ensure the highest quality video and audio signal transmission. For consumers, HDMI technology not only provides clear picture quality, but also greatly simplifies the installation of home theater systems because audio/video uses the same cable. However, the existing HDMI cables have a single function, and the driving current required for HDMI data transmission requires external wiring, which is cumbersome, difficult to construct, and low in efficiency. In addition, the HDMI cables on the market have poor ability to withstand static electricity and electromagnetic interference, and the shielding effect cannot be achieved. Meet the needs.
