Multiplexers expand video input and output capabilities for consumer electronics Design How-To 2/6/2006 Post a comment Although most video codec chips have integrated analog multiplexers, the number of inputs may not be sufficient to accommodate today's variety of video sources available to consumers. The same applies to the serial digital stream, where signal routing may be required to connect multiple devices to the same bus. A cost-effective solution to this problem is to use external multiplexers to increase the number of inputs to the existing video codec.
