This paper provides an overview of SHVC, the scalable extensions of the High Efficiency Video Coding (HEVC) standard, published in the second version of HEVC. In addition to the temporal scalability already provided by the first version of HEVC, SHVC further provides spatial, SNR, bit depth, and color gamut scalability functionalities, as well as(More)
Multiple description codes have been shown to facilitate heterogeneous multicast using routing with replication. We develop the combination of practical network coding and multiple description coding (introduced by Chou ), but here for video multicast in lossless networks where users get video according to their available resources. We also show that(More)
Multiple Description with Forward Error Correction (MD-FEC) coding provides the flexibility, easy adaptivity and distortion-rate optimality that are desirable for delivering streaming video in a network environment with time-varying bandwidth fluctuations and random packet losses. In this paper, we consider the issue of how diverse receivers of a video(More)
This paper presents a method for efficient compression of high dynamic range (HDR) and wide color gamut (WCG) video data. The proposed solution consists of two major elements: a conventional video codec (e.g., HEVC) and pre-and post-processing steps applied prior to encoding and after decoding process, respectively. The proposed HDR/WCG video coding system(More)
In this paper, we propose an approach that combines statistical multiplexing and Multiple Description with Forward Error Correction (MDFEC) coding to make the optimal use of server bandwidth, taking into account the dynamically evolving content (complexity) of the different videos being streamed by the server, and path bandwidths and loss rates experienced(More)
