In a broadcast control room, the number of video and audio cables of each signal is very large. At the same time, because the location is very concentrated, if each cable is not coded, it will be extremely difficult for future maintenance. Great inconvenience. The method is very simple. Before making the connector, put the wire code on both ends of the video and audio cable according to the pre-coded number. The principle of coding is simple and intuitive. Coding that is too complex or too abstract is also inconvenient to maintain.
It is recommended to use a combination of letters and numbers, such as: VD101 represents the first output port (01) of the video (V) distributor (D) No. 1 unit (1). This set of codes illustrates: 1. Signal nature: video signal; 2. Signal source: video distributor; 3. Equipment number: No. 1 machine; 4. Port location: No. 1 output port.
