Abstract
Predmet rada je hijerarhijsko kodiranje video signala prema MPEG-2 normi, primjenjeno kao metoda kontrole pogrešaka u prijenosu video signala kanalima s gubicima. Analizirani su uzroci visoke osjetljivosti na pogreške u prijenosu MPEG-2 kodiranog video slijeda, posljedice istih, metode kontrole pogrešaka, kao i metode za povećanje otpornosti na pogreške. Analizirana je otpornost na pogreške u prijenosu osnovnog i podatkovno podijeljenog MPEG-2 video slijeda. Za povećanje otpornosti na pogreške u prijenosu MPEG-2 podatkovno podijeljenog video slijeda, korišten je EREC (Error Resilient Entropy Code) koder u sloju profinjenja. Analiziran je prijenos kanalima sa slučajnim i snopovitim pogreškama bita, kao i prijenos paketskim mrežama, zasnovanima na ATM i IP tehnologiji, karakteriziranim slučajnim i snopovitim gubicima paketa. Rezultati pokazuju da osnovni sloj MPEG-2 podatkovno podijeljenog video slijeda, jednako kao i jednoslojni MPEG-2 video slijed, mora biti snažno zaštićen od pogrešaka u prijenosu i prenošen skoro bez pogrešaka. Uz idealno zaštićeni osnovni sloj, sloj profinjenja podatkovno podijeljenog video slijeda podnosi mnogo više pogrešaka. Otpornost na pogreške u prijenosu sloja profinjenja može se dodatno povećati koristeći EREC kodiranje sve dok nije izgubljen značajan dio EREC okvira kao posljedica pogrešaka u prijenosu.
Abstract (english)
This thesis considers hierarchical coding of MPEG-2 video bitstream as an error resilience tool for video transmission over lossy channel. Causes of high susceptibility to transmission errors, effects of transmission errors, error control methods and methods for error resilience enhancement are analyzed. An error performance analysis of MPEG-2 nonlayered video bitstream and data partitioning coded video bitstream is provided. To improve error resilience of the enhancement layer, Error Resilient Entropy Coding (EREC) of data partitioning enhancement layer data is developed. Transmission of video bitstreams over channel subject to random and bursty bit errors is analysed. Effects of random and bursty packet loss in video bitstream transmitted over ATM and IP networks are considered. Results show that base layer of data partitioning coded video bitstream, as well as nonlayered video bitstream, must be heavily protected and transmitted almost error-free. More errors can be tolerated in the enhancement layer if base layer is ideally protected. Error performance of the enhancement layer can be further improved using EREC coder but only if no significant part of EREC frame is lost due to the transmission errors.
