The Effects of Priority Levels and Buffering on the Statistical Multiplexing of Single-Layer H.264/AVC and SVC Encoded Video Streams

by Sudhir Kumar Srinivasan, Jonathan Vahabzadeh-hagh, Martin Reisslein
"... Abstract—H.264/Advanced Video Coding (AVC) employs classical bi-directional encoded (B) frames that depend only on intracoded (I) and predictive encoded (P) frames. In contrast, H.264 Scalable Video Coding (SVC) employs hierarchical B frames that depend on other B frames. A fundamental question is h ..."

Performance Analysis of SVC

by Mathias Wien, Heiko Schwarz, Tobias Oelbaum - IEEE Transactions on Circuits and Systems for Video Technology , 2007
"... Abstract—This paper provides a performance analysis of the Scalable Video Coding (SVC) extension of H.264/AVC. A short overview presenting the main functionalities of SVC is given and main issues in encoder control and bit stream extraction are out-lined. Some aspects of rate-distortion optimization ..."

H.264/SVC ROI ENCODING WITH SPATIAL SCALABILITY

by Lino Ferreira, Pedro Assunção
"... Abstract: This paper proposes two H.264/AVC compliant methods for encoding Regions-of-Interest (ROI) with spatial scalability and evaluates their respective rate-distortion-complexity performance. The base layer is kept unchanged and provides lower resolution images with roughly constant quality, wi ..."

R-d optimized multi-layer encoder control for SVC,"

by Heiko Schwarz , Thomas Wiegand - Proceedings of ICIP'07, , 2007
"... ABSTRACT The scalable video coding (SVC) extension of H.264/AVC was recently standardized. The encoder control that is described in the Joint Scalable Video Model for SVC specifies a bottom-up process in which first the base layer and then the enhancement layer is encoded. The base layer is encoded ..."

H.264/SVC Performance and Encoder Bit- stream Analysis

by Amina Kessentini, Imen Werda, Amine Samet, Mohamed Ali, Ben Ayed, Nouri Masmoudi
"... With the introduction of diverse variety of display transmission and resolutions channel capacities, the Joint Video Team (JVT) has developed the H.264/SVC as an extension of H.264/AVC. In fact, it provides a single compressed bit-stream with several scalability levels. Such a dataflow needs to be a ..."

Implications of Smoothing on Statistical Multiplexing of H.264/AVC and SVC Video Streams

by Geert Van Der Auwera, Martin Reisslein
"... Abstract—While the hierarchical B frames based Scalable Video Coding (SVC) extension of the H.264/AVC standard achieves sig-nificantly improved compression over the initial H.264/AVC codec, the SVC video traffic is significantly more variable than H.264/AVC traffic. The higher traffic variability of ..."

of the SVC encoder can lead to smaller numbers of streams supported with bufferless statistical multiplexing than with the H.264/AVC encoder (and even less streams than with the MPEG-4 Part 2 encoder) for prescribed link capacities and loss constraints. In this paper we examine the implications of video

Format-compliant Encryption of H.264/AVC and SVC

by Thomas Stütz, Andreas Uhl , 2008
"... An encryption approach for H.264/AVC and SVC is proposed. Although the bitstream (format stream) is encrypted with state-of-the-art symmetric ciphers, H.264/AVC and SVC compliance is preserved. Standard compliant encoder/decoder and conventional symmetric ciphers, e.g., in specialized hardware, can ..."

MULTIDIMENSIONAL SVC BITSTREAM ADAPTATION AND EXTRACTION FOR RATE-DISTORTION OPTIMIZED HETEROGENEOUS MULTICASTING AND PLAYBACKW

by Wen-hsiao Peng, John K. Zao, Hsueh-ting Huang, Tse-wei Wang, Lun-chia Kuo
"... In this paper, we propose an optimal SVC bitstream extraction scheme that can produce scalable layer representations for different viewing devices scattered over a multicasting network with diverse link bandwidth. Our scheme can determine optimal extraction or-ders/paths that are implementable at di ..."
Abstract - Add to MetaCart
. Extensive SVC encoding and adaptation experiments have been per-formed using JSVM 9 and both objective quality metrics (PSNR and MSE) as well as subjective metric (VQM). The experiment results showed that our scheme works well if convexity of R-D performance is maintained throughout the SVC bitstream.
