Claim 0:
1. A video decoding system for simultaneously decoding a plurality of encoded video streams of one or more video compression formats and displaying each resulting decoded video stream in a predetermined tile of a display, the system comprising:
a data interface in use receiving said plurality of encoded video streams;
a multi-core central processing unit (CPU) in signal communication with the data interface;
a display control device in signal communication with the CPU, the display control device comprising at least one graphical processing unit (GPU); and
a display in signal communication with the display control device,
wherein the data interface is configured to direct each of the plurality of encoded video streams to be decoded by only one of the CPU and the GPU, and, generate for a given one of the plurality of encoded video streams decoded only by the GPU a stream analysis result, said result representing at least a non-standard or an unexpected change in stream parameters, and in response to said stream analysis result, redirect said given one of said encoded video streams from being decoded by the GPU to being decoded only by the CPU.
