Abstract
A system for switching video of two different standards that uses a single crosspoint matrix and a single local controller coupled to two memory blocks for storage of crosspoint selection data. The crosspoint selection data is written to the crosspoint matrix according to the video reference signals that correspond to the crosspoint selection data to be written. Switching of the crosspoints then occurs according to the video reference signal corresponding to the crosspoints to be switched.
