Description

Decoder based on wired network Technical Field The utility model relates to the technical field of decoders, in particular to a decoder based on a wired network. Background When HDMI audio/video signals are transmitted over long distances, the image quality is seriously affected as the transmission distance increases, the image may be blurred, shifted or flickered, and the audio signal may be delayed or interrupted. This phenomenon is particularly prominent in large venues, for example, the distance between the stage and the audience may reach tens of meters or even hundreds of meters, and the transmitted HDMI audio and video signals may be lost or delayed, which results in asynchronous viewing and listening and affecting the overall effect of the performance. In order to solve this problem, it is generally necessary to customize a cable of a special wire process to realize high-quality HDMI audio and video signal transmission. Because of the wide distribution of equipment in large venues, audio and video signals need to be transmitted from a stage to a plurality of display terminals and equipment expansion, which means that the cable length needs to be accurately measured, and complex construction including cable laying, interface installation and the like is performed on site. In practical situations, the stage arrangement and the equipment position may need to be adjusted at any time according to the performance requirement, such as the equipment position adjustment or the stage layout change, and the re-wiring is needed, and once the customized long-distance cable is installed, the adjustment is difficult according to the field requirement, which greatly limits the flexibility of the stage arrangement and the improvement of the performance effect, increases the construction cost, and may also cause delay of the whole performance progress.
