Abstract

The invention provides an HDMI photoelectric hybrid transmission system, which comprises a transmitting terminal HDMI, a receiving terminal HDMI and a signal line connecting the transmitting terminal HDMI and the receiving terminal HDMI, and is characterized in that a transmitting terminal photoelectric module is arranged in the transmitting terminal HDMI, the transmitting terminal photoelectric module comprises a transmitting terminal circuit board, and a ground capacitance adjusting circuit is integrated on the transmitting terminal circuit board; and / or, a receiving end photoelectric module is arranged in the receiving end HDMI, the receiving end photoelectric module comprises a receiving end circuit board, and a ground capacitance adjusting circuit is integrated on the receiving end circuit board. According to the invention, the capacitance value of the signal line of the low-frequency control clock signal and / or the low-frequency control data signal to the ground can be freely adjusted, so that the self-control capability of the HDMI photoelectric hybrid transmission system for the transmission distance is greatly improved on the premise of ensuring the stability of the HDMI photoelectric hybrid transmission system for transmitting the low-frequency control signal.

Description

【Technical field】 [0001] The invention relates to the technical field of signal transmission, in particular to an HDMI photoelectric hybrid transmission system. 【Background technique】 [0002] High Definition Multimedia Interface (HDMI) is a fully digital video and sound transmission interface that can send uncompressed audio and video signals, and is widely used in set-top boxes, DVD players, personal computers, TVs, game consoles, Electronic equipment such as integrated amplifiers, digital audio and televisions. HDMI is usually connected with signal wires (such as copper wires) to form an HDMI transmission system. In recent years, due to the limitation that copper wires cannot meet ultra-long-distance transmission, an HDMI optical-electrical hybrid transmission system composed of HDMI and optical fiber has emerged as the times require. [0003] In the prior art, the HDMI optoelectronic hybrid transmission system generally includes a transmitting terminal HDMI with a built...
