Scalable coding provides many advantages for video transmission over packet networks that lack Quality-of-Service (QoS) guarantees. Meanwhile, it is well known that the benefits of scalable coding come at the expense of degradation in video quality or reduction in coding efficiency when compared with non-scalable video compressed at a particular bitrate. Recently, the notion of TranScaling (TS)...

In this work we present a video transmission system for packet lossy channels based on the Progressive Texture Video Coding (PTVC) algorithm. A posteriori video rate control on the progressively coded messages is simplified significantly as for rate adaptation only the later part of this message can be truncated. This property is used by an appropriate unequal erasure protection (UXP) scheme wh...

We describe a framework for video transmission over the Internet that features the coordinated operation of an application-layer video source coding algorithm and a transport-layer rate control mechanism. The proposed video coding scheme operates on a progressively encoded video stream and provides graceful resilience to network packet drops. The robustness is enabled through a generalized Mult...

The need for adapting video stream delivery over heterogeneous and unreliable networks requires self-adaptive and error resilient coding.Network bandwidth fluctuations can be handled bymeans of a video coding schemewhich adapts to the channel conditions. However, packet losses which are frequent in wireless networks can cause a mismatch during the reconstruction in the receiver end and result i...

Srinath R. Joshi. Packet Loss Recovery for Unicast Interactive Video Transmission over the Internet. (Under the direction of Professor Injong Rhee.) The current Internet is not reliable; packet loss rates are frequently high, and varying over time. Transmitting high-quality interactive video over the Internet is challenging because the quality of compressed video is very susceptible to packet l...

This paper presents a video transmission system using layered multiple description (coding (MDC) and multi-path transport for reliable video communications in wireless ad-hoc networks. The proposed MDC extends a quality-scalable H.264/AVC video coding algorithm to generate two independent descriptions. The two descriptions are transmitted over different paths to a receiver in order to alleviate...

Transmission of video over wireless and mobile networks requires a scalable solution that is capable of adapting to the varying channel conditions in real-time (bit-rate scalability). Furthermore, video content needs to be coded in a scalable fashion to match the capabilities of a variety of devices (complexity scalability). These two properties—bit rate and complexity scalability—provide the f...

Video communication over lossy packet networks such as the Internet is hampered by limited bandwidth and packet loss. This paper presents a system for providing reliable video communication over these networks, where the system is composed of two subsystems: (1) multiple state video encoder/decoder and (2) a path diversity transmission system. Multiple state video coding combats the problem of ...

This paper proposes an integrated approach to Internet video streaming and multicast (e.g., receiver-driven layered multicast (RLM) by McCanne) based on combined wavelet video coding and error control. We design a packetized wavelet video (PWV) coder to facilitate its integration with error control. The PWV coder produces packetized layered bitstreams that are independent among layers while bei...

Streaming of precoded video, which is both source and channel coded, over wireless networks faces challenges of time-varying packet loss rate and fluctuating bandwidth. Rate shaping has been proposed in [1] to “shape” the precoded video to adapt to the real-time bandwidth requirement and the packet loss rate. In this paper, we propose a novel “fine-grained rate shaping (FGRS)” scheme to allow f...
