Automatisk feldetektion och växling mellan rendundanta videosignaler, med fokus på loop detektion. (Swedish)
Abstract [en]

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.

Abstract [sv]

Denna rapport beskriver arbete utfört med att implementera automatisk detektion av loopande följder av bildrutor i en videosignal. Den centrala algoritmen för igenkänning av loopar beskrivs. För att förbättra beräkningshastighet tillämpas hashning av bildrutor. Två videosignaler jämförs med avseende på deras innehåller av loopar, och växling av uppspelad signal sker baserat på utvärdering av signalernas kvalitet. Upprepade följder, skilt från loopande följder, diskuteras. Tankar för vidare utveckling av en mer heltäckande paketlösning för detektion av olika typer av fel i videosignaler presenteras kort.
