Abstract

The invention discloses a high definition multimedia interface (HDMI) video transmission line. The transmission line comprises a tubular external insulation layer, wherein a tubular cavity is arranged in the tubular external insulation layer, three HDMI video transmission sub-lines, a USB transmission sub-line and two RF transmission sub-lines are arranged in the tubular cavity, the USB transmission sub-line and the tubular cavity are coaxially arranged, the three HDMI video transmission sub-lines and the two RF transmission sub-lines encircle the periphery of the USB transmission sub-line, each HDMI video transmission sub-line comprises an HDMI transmission line, a first aluminum foil layer, a first metal weaving layer and a first grounding line, the first metal weaving layer is of a tubular structure, the first aluminum foil layer is arranged on an internal circumferential surface of the first metal weaving layer, the HDMI transmission line is arranged in the tubular cavity encircled by the first aluminum foil layer, and the first grounding line is arranged between the first metal weaving layer and the first aluminum foil layer.

Description

technical field [0001] The invention relates to the technical field of high-definition video and audio signal transmission, in particular to an HDMI video transmission line. Background technique [0002] HDMI (High Definition Multimedia Interface) is a transmission interface developed for multimedia audio-visual equipment, and it is a new interface that ends the separation of audio-visual transmission in the past. In addition to transmitting image data, the HDMI video transmission line can also transmit 8-channel audio signals at the same time, using uncompressed digital data transmission, which can effectively reduce signal interference and attenuation caused by digital / class conversion. Only one HDMI video transmission line is needed to transmit audio and video signals at the same time, without the need for multiple wire connections, which greatly simplifies the installation of the home theater system. [0003] In addition to HDMI video transmission lines, commonly used t...
