ABSTRACT:
A method and apparatus for simultaneously recording and displaying video signals from two different video sources. The apparatus comprises a main channel processing circuit, a second channel processing circuit, and common circuitry. The common circuit comprises a digital video decoder pipe that decodes both first and second encoded video signals. A PIP picture is produced using a common reference clock that is derived from the first video signal. In a record mode, a second channel clock reference is coupled to the second channel processing circuit to produce a recordable signal using a digital encoder. The recordable signal also forms a PIP picture that is coupled to the main channel processing circuit to produce a PIP picture that is used to monitor the recording process.
