An approach to synthesizing missing pixels in video images. The invention synthesizes an outermost ring of pixels within a block of missing pixels, based on adjacent, known, pixels. Then, the invention synthesizes the next-outermost ring, using, in part, pixels synthesized in the outermost ring, and proceeds in this manner to the innermost ring.

Spatial error concealment for image processing

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.
