Abstract:
1. In a system having a processor connected to a keyboard and to a camera through a flexible cable that is subject to stress during system operation, the camera providing a high speed data output and a horizontal synchronization signal, the improvement comprising: a first interface that receives parallel high speed data from said camera, a second interface that receives parallel slower speed data from said keyboard, a controller and data multiplexer that forms an interleaved sequence of the high speed camera data and slower speed keyboard data, the slower speed keyboard data being passed during the camera's horizontal synchronization signals; when the camera is passing no data, the controller and data multiplexer generates artificial or pseudo horizontal synchronization signals wherein keyboard data may be passed during the artificial or pseudo horizontal synchronization signals; and a serializer that receives the interleaved time sequence of parallel data from the multiplexer and outputs the interleaved sequence of parallel data in a serial data fashion at a single data rate over a single data line in said cable together with a single serial clock over another line.
