METHOD AND APPARATUS FOR SIMULTANEOUS RECORDING AND DISPLAYING TWO DIFFERENT VIDEO PROGRAMS |
摘要 |
<p>A method and apparatus for simultaneously recording and displaying video signals from two different video sources. The apparatus comprises a main channel processing circuit/logic, a second channel processing circuit/logic, and common circuitry/logic. The common circuitry comprises a digital video encoder pipe that decodes both a first and second encoded video signals. The main channel processing circuit processes a first decoded video signal utilizing a first clock to form a main picture for display. The second channel processing circuit processes a second decoded video signal to form a PIP picture for combination with the main picture for display. The PIP picture is produced using a second clock signal that is independent from the first clock signal. In a record mode, the second channel clock is coupled to the second channel processing circuit to produce a recordable signal using a digital encoder. The recordable signal also forms the PIP picture that is coupled to the main channel processing circuit to produce a PIP picture that is used to monitor the recording process.</p> |
