Robust video multicast in erasure networks using network coding (NC) to reduce the impact of packet loss is studied in this paper. In our proposed solution, random linear network coding (RLNC) is adopted at intermediate nodes of the network. RLNC linearly combines a group of packets by randomly selecting weighting coefficients on a finite field, and the loss of an RLNC-coded packet is equivalen...

This paper presents a robust scalable video coding scheme with leaky prediction, suitable for time-varying error-prone channels, such as the Internet or wireless channels. The proposed scheme shows how leaky prediction can be utilized for efficient motion-compensated video coding, as well as for robust video transmission over packet erasure networks. We show that leaky prediction with a tempora...

The proliferation of video streaming applications that distribute data to a large number of clients motivates the design of fast and reliable multimedia delivery systems capable to adapt effectively to diverse transmission conditions. Receiver-driven layered multicast (RLM) efficiently addresses the issue of heterogeneity in clients’ available bandwidths and packet loss rates by shifting rate c...

The MIT Faculty has made this article openly available. Please share how this access benefits you. Your story matters. Multiple description (MD) video coding can be used to reduce the detrimental effects caused by transmission over lossy packet networks. A number of approaches have been proposed for MD coding, where each provides a different tradeoff between compression efficiency and error res...

ERROR-RESILIENT IMAGE AND VIDEO CODING OVER LOSSY NETWORKS Publication No. YILONG LIU, Ph.D. The University of Texas at Arlington, 2005 Supervising Professor: Soontorn Oraintara The rapid growth of the Internet and increasing bandwidth in the past decade has heightened the interest in robust transmission of image and video signals over error-prone links. Recent literatures highlight the multipl...

This memo describes an RTP payload format for the video coding standard ITU-T Recommendation H.265 and ISO/IEC International Standard 23008-2, both also known as High Efficiency Video Coding (HEVC) and developed by the Joint Collaborative Team on Video Coding (JCT-VC). The RTP payload format allows for packetization of one or more Network Abstraction Layer (NAL) units in each RTP packet payload...

Delivering temporally-constrained multimedia streams in heterogeneous environments, ooering no guarantee in terms of bandwidth, packet loss, or delay, is a a very challenging problem faced today by both the networking and the coding community. Layered coding is often proposed as a solution for rate-based congestion control of video transmission in heterogeneous environments. The problem address...

Although great advances have been realized in wireless networking over the last ten (10) years, the wireless transport medium is not ideal for multimedia video applications. This paper proposes the basis for a study in quantitatively understanding the effect in deploying various combinations of video encoding and network coding approaches on peer-to-peer streaming systems in a wireless environm...

We consider factors not only in a packet, but also in its locality, to account for possible temporal and spatial masking effects. We apply our visibility model to packet priority for a video stream, when the network gets jam-packed at an in-between router; the router is able to choose which packets to drop such that visual quality of the video is minimally crashed. To show the effectiveness of ...
