Overview of the scalable video coding extension of the H.264/AVC standard
- IEEE TRANSACTIONS ON CIRCUITS AND SYSTEMS FOR VIDEO TECHNOLOGY IN CIRCUITS AND SYSTEMS FOR VIDEO TECHNOLOGY
, 2007
"... With the introduction of the H.264/AVC video coding standard, significant improvements have recently been demonstrated in video compression capability. The Joint Video Team of the ITU-T VCEG and the ISO/IEC MPEG has now also standardized a Scalable Video Coding (SVC) extension of the H.264/AVC stand ..."

relative to the scalable profiles of prior video coding standards. This paper provides an overview of the basic concepts for extending H.264/AVC towards SVC. Moreover, the basic tools for providing temporal, spatial, and quality scalability are described in detail and experimentally analyzed regarding
Optimal Quality Adaptation for MPEG-4 Fine-Grained Scalable Video
- in Proc. IEEE INFOCOM’03
, 2003
"... Dynamic behavior of the Internet's transmission resources makes it difficult to provide perceptually good quality of streaming video. MPEG-4 Fine-Grained Scalable coding is proposed to deal with this problem by distributing the data in enhancement layers over a wide range of bit rates. However, ..."

Real-Time Internet Video Using Error Resilient Scalable Compression and TCP-Friendly Transport Protocol
, 1999
"... We introduce a point to point real-time video transmission scheme over the Internet combining a low-delay TCP-friendly transport protocol in conjunction with a novel compression method that is error resilient and bandwidth-scalable. Compressed video is packetized into individually decodable packets ..."

of equal expected visual importance. Consequently, relatively constant video quality can be achieved at the receiver under lossy conditions. Furthermore, the packets can be truncated to instantaneously meet the time varying bandwidth imposed by a TCP-friendly transport protocol. As a result, adaptive flows
Utilizing Scalable Video Encoding for Adapted Video Delivery in Next Generation Networks
"... Abstract—Multimedia services are the cornerstone of the Next Generation Network (NGN) architectures and judging by the success of video services in the Internet, future multimedia applications will be heavily video dependent. Due to the heterogeneous nature of the access networks and the range of en ..."

the limitations of these current solutions is clearly desirable. The recently completed H.264/MPEG4-AVC Scalable Video Coding (SVC) amendment allows for extraction of multiple quality layers with varying spatial, temporal and quality attributes from a single encoding. In this paper we present a video streaming
ContentAdaptive Spatial Scalability for Scalable Video Coding

"... Streaming audio and video applications are becoming increasingly popular on the Internet, and the lack of effective congestion control in such applications is now a cause for significant concern. The problem is one of adapting the compression without requiring video-servers to re-encode the data, an ..."

, 1999
"... Abstract—In this paper, we present a new wavelet based rate scalable video compression algorithm. We will refer to this new technique as the Scalable Adaptive Motion Compensated Wavelet (SAMCoW) ) algorithm. SAMCoW uses motion compensation to reduce temporal redundancy. The prediction error frames a ..."

An adaptive motion compensation (AMC) scheme is described to address error propagation problems. We show that, using our AMC scheme, the quality of the decoded video can be maintained at various data rates
Adaptive bitstream switching of pre-encoded PFGS video
- in: Proceedings of the ACM Workshop on Advances in Peerto-peer Multimedia Streaming, 2005
"... With Progressive Fine Granularity Scalability (PFGS) video coding, one given encoding (with a prescribed bit rate) can flexibly be transmitted at any lower bit rate. However, the transmitted video is only efficiently encoded when the transmission bit rate is in the vicinity of the encoding bit rate; ..."
