An analysis on the effect of transmission errors in real-time H.264-MVC bit-streams

Abstract

This paper studies the quality of transmitted multi-view video when the corrupted packets are not discarded by the underlying protocols of the decoder. It assumes a wireless channel where the errors can be significant and implements solutions within the current H.264-MVC to reduce their impact on the video quality perceived by the user. The results show that transmission errors drastically reduce the quality of the reconstructed 3D video and confirm that a new type of error propagation between views exists. Furthermore, employing the Context Adaptive Variable Length Coding (CAVLC) entropy encoder, coding and transmitting the video streams in smaller packets, and having a small cyclic-Intra coded period, all improve the error resilience of the system.
