New robust decoding scheme-aware channel condition for video streaming transmission

Abstract

H.264 standard, known as an efficient video codec, is still sensitive to transmission errors. This issue is achieved by several error resilience/concealment techniques, to deal with packet losses. Whereas, these typical techniques are not suited for streaming video transmission which requires high quality. In fact, since the H.264 standard provides different type of frame, these techniques don’t give high priority to I frames. Moreover, video transmission over error prone channel has increased greatly. These facts provided the necessary to propose a new technique to deal with errors in video streaming over noisy channels. In this paper, we propose a novel technique, named novel robust decoding algorithm-aware channel conditions for video streaming (denoted as RDVS). The main idea of RDVS is to estimate CAVLC sequence by exploiting the bitstream structure and the semantic property. Obtained results confirm the effectiveness of the proposed strategy which outperforms the existing state-of-the-art Robust Decoding strategies.
