Gop Size

Video transmission over IP networks requires appropriate conditions of quality of service, in order to ensure the integrity of the image, which still represents a challenge to be overcome in wireless mesh networks due to traffic capacity limitations inherent to its architecture. In this work we evaluate the performance of high-resolution video over multihop mesh networks and we propose a suitable GOP size for encoding video to be streamed, based on traffic conditions to minimize the loss of quality. Experiments were carried out in a wireless mesh network planned for real testing within a 1500m 2 area of the main UFAM campus, using the IEEE 802.11a and 802.11n network standards.

Wyner-Ziv video coding has become one of the hottest research topics in the video coding community due to the conceptual, theoretical and functional novelties it brings. Among the many practical architectures already available, feedback channel-based with channel coding, e.g. LDPC and turbo codes, solutions are rather popular. These solutions rely on decoder motion estimation based on periodic Intra coded key frames, setting the so-called GOP size, very much like in conventional video coding. This paper targets the ratedistortion and complexity performance study of this type of Wyner-Ziv coding solution as a function of the GOP size, considering both LPDC and turbo codes.
