ABSTRACT:
An apparatus and method for centralized processing of PIP images from a plurality of digital video sources includes a centralized processing device having a plurality of service drivers for outputting digital video data representing full screen images, and samplers for selectively sampling the data from the service drivers to form reduced screen images. A PIP bus channels the sampled data for access by various users. The sample data is selectively stored in buffers and is output to a display device when triggered by input/output triggers. The triggered output data representing reduced screen images is then combined by a video switch to form picture-in-picture images.
