Description

technical field [0001] The invention relates to a visual intercom system in an intelligent community or an intelligent building, in particular to an audio-video network converter and a data conversion method thereof. Background technique [0002] The current visual intercom system used in smart communities or smart buildings is mainly based on bus-based analog transmission. When the system scale is slightly larger, the system is busy, audio and video signals are attenuated after long-distance transmission, and the system has a single function. Lack of scalability; the wiring method of the bus system needs to include a variety of different specifications of wires such as video cables, audio cables, and control cables, which have various limitations such as high cost, complicated construction, and difficult maintenance. Contents of the invention [0003] The present invention aims at the above problems, utilizes the broadband network of the community, and makes full use of t...
