视频切换矩阵多用于播控中心和转播系统。而用于发射台作为信号切换时,除具备其本身的优点外,还具有其它一些长处。我们利用8×8(8路输入,8路输出)矩阵对传统的控制桌切换进行改造。经过近一年的运行,效果确实不错。1.提高了信号质量我台已改用光纤传输信号,信号质量上了一个台阶。但是传统控制桌的视频继电器切换在稳定性、插入损耗等方面已不能更好地满足要求。
Video switching matrix and more for broadcast center and broadcast system. When used as a signal switching transmitter station, in addition to its own advantages, but also has other advantages. We use the 8 × 8 (8 input, 8 output) matrix to transform the traditional control table switch. After nearly a year of operation, the effect is indeed good. 1. Improve the signal quality I have been using optical fiber transmission signal, the signal quality on a higher level. However, the traditional video control relay table switching in terms of stability, insertion loss, etc. can not better meet the requirements.
