Automatic error detection and switching of redundant video signals, with focus on loop detection

Abstract: This report describes work done on implementing automatic detection of looping frame sequences in a video signal. The central loop detection algorithm is described. Hashing of video frames is used as a means of improving computational performance. Two video signals are compared with respect to containing loops, and switching of displayed stream is done based on evaluated stream qualities. Repeating sequences -distinct from looping sequences- are also discussed, as well as cursory thoughts for further work on implementing a more comprehensive error detection package for video signals.
