Video transmission using scalable video coding (SVC) enables the functionalities of adaptation for both channel bandwidth and terminal device. However, link adaptation, which requires the video bitstream to provide error resilient scalability, is currently not supported in SVC. In this paper, we propose a robust SVC bitstream transmission framework, which integrates both error resilient coding and error concealment to enable the desired link adaptability. First, at the encoder, we design an error resilient coding scheme for SVC using redundant pictures, in which redundant picture information (RPI) is generated under rate-distortion criteria and transmitted to the media gateway together with the SVC bitstream. Then, error resilient scalability can be effectively achieved at the media gateway by selectively, adding, or removing coded pictures of different video coding layers according to the RPI and current network link status. Finally, at the decoder, we take advantage of the unique characteristics of SVC to develop an error concealment scheme based on both the proposed Virtual-BLSkip method and Wiener filtering in order to recover the lost or removed enhancement layer pictures. The proposed framework has negligible impact on the coding efficiency because it transmits RPIs rather than directly adding redundancy into the original bitstream. More importantly, it successfully strikes a balance between coding efficiency, error resiliency, and operation complexity. It is capable of providing the desired error resilient scalability with extremely low complexity, and maintaining virtually the same bitrate as input video bitstream. The experimental results show that the proposed framework achieves significant performance gains over existing error resilient transmission schemes.Index Terms-Video coding, video communication, scalable video coding, error resilient coding, error concealment, link adaptation.

“…Also, a rate-distortion optimized scheduling algorithm was presented to adapt the streaming video over time-varying channels for minimizing the total distortion under the transmission rate constraint [18,19]. There have been research studies on transmitting SVC video sequence safely over multicast channel or MIMO wireless systems using Raptor codes [20][21][22], research studies on the priority-based SVC or SHVC video streaming over multi-channel were introduced in [23,24], and research studies on the UEP method with Raptor codes with SVC or HEVC temporal layer priorities have been presented in [25][26][27][28][29].…”

This paper describes a three-screen television system using a block recovery rate (BRR)-based unequal error protection (UEP). The proposed in-home wireless network uses scalable video coding (SVC) and UEP with forward error correction (FEC) for maximizing the quality of service (QoS) over error-prone wireless networks. For efficient FEC packet assignment, this paper proposes a simple and efficient performance metric, a BRR which is defined as a recovery rate of temporal and quality layer from FEC assignment by analyzing the hierarchical prediction structure including the current packet loss. It also explains the SVC layer switching scheme according to network conditions such as packet loss rate (PLR) and available bandwidth (ABW). In the experiments conducted, gains in video quality with the proposed UEP scheme vary from 1 to 3 dB in Y-peak signal-to-noise ratio (PSNR) with corresponding subjective video quality improvements.
