Problems solved by technology

[0002] At present, in audio / video data transmission, high-definition multimedia interface (HDMI, High Definition Multimedia Interface) has been widely concerned because it does not need to compress audio / video data and can present high-resolution audio / video signals, but in long-distance transmission In the audio / video data scenario, the existing HDMI is either prone to signal distortion or expensive. Therefore, the currently used HDMI is not suitable for long-distance audio / video data transmission.

Abstract

The invention discloses a data transmission system and method. The system includes: at least two sub-transmission systems, wherein; the first sub-transmission system in the at least two sub-transmission systems is a passive optical network PON sub-transmission system; in the PON sub-transmission system, the optical line terminal OLT A multiplexing unit is provided between the optical network unit ONU; the multiplexing unit is used to couple the first data transmitted in the PON sub-transmission system with the second data transmitted in other sub-transmission systems together for transmission Correspondingly, the ONU is provided with a demultiplexing unit corresponding to the multiplexing unit; the demultiplexing unit is used to separate the first data from the second data, and transmit the first sending data to the first terminal; transmitting the second data to the second terminal, wherein the other sub-transmission system is a sub-transmission system of the at least two sub-transmission systems except the first sub-transmission system.

Description

technical field [0001] The present invention relates to the technical field of data transmission, and in particular, to a data transmission system and method. Background technique [0002] At present, in audio / video data transmission, High Definition Multimedia Interface (HDMI, High Definition Multimedia Interface) has attracted widespread attention because it does not require audio / video data compression and can present high-resolution audio / video signals. In the audio / video data scenario, the existing HDMI is either prone to signal distortion or expensive. Therefore, the currently used HDMI cannot be suitable for long-distance audio / video data transmission. SUMMARY OF THE INVENTION [0003] In view of this, the main purpose of the present invention is to provide a data transmission system and method, which can ensure long-distance transmission of high-quality audio / video data before cost reduction. [0004] In order to achieve the above object, the technical scheme of t...
