And a plurality of video sources, integrated video processing system for implementing a picture in a picture in the on-screen display graphics

摘要

PURPOSE: An integrated video processing system having plural video source for realizing picture-in-picture by on-screen display graphics is provided to apply simultaneous plural picture display functions by adding a P-in-P function at the minimum costs to an integrated digital video system such as a digital video set top box or a digital video disk player. CONSTITUTION: A 2:1 MUX(202) selects any of an extended video, a non- compressed video, and a video obtained by setting the expanded or non- compressed video in a P-in-P display support according to a pixel selection control signal from a processor, and transmits it to an OSD mixing logic(204) as a basic input. Also, the arrangement and size of inserted pictures can be arbitrarily controlled. Moreover, ODS graphics can be superimposed on an OSD mixing logic(204), and they are integrated and transmitted to a display device. Those functions can be integrated into an integrated digital video system as one chip.
