“…Extended quality layering can also be applied to video streaming across WiMAX. In [30], adaptive multicast streaming was proposed for WiMAX using the Scalable Video Coding (SVC) extension for H.264. WiMAX channel conditions were monitored in order to vary the bitrate accordingly.…”

“…WiMAX channel conditions were monitored in order to vary the bitrate accordingly. Unfortunately, the subsequent decision of the JVT standardization body for H.264/AVC not to support fine-grained scalability (FGS) implied it will be harder to respond to channel volatility in the way proposed in [30]. Other work concerned with video streaming over WiMAX links has also investigated: combining scalable video with multi-connections in [31]; and compared [32] H.264/SVC with H.264/AVC for WiMAX.…”

“…The network aware adaptation of end systems is often used to avoid congestion in the network, e.g., in conjunction with a transport protocol like TFRC [15]. A framework that uses TFRC for efficient congestion aware SVC video delivery has been proposed in [17]. Rate smoothness and real-time requirements for video streaming are addressed in [16].…”

Abstract-Thanks to its in-network drop-based adaptation capabilities, H.264 Scalable Video Coding is perceived as an effective approach for delivering video over networks characterized by sudden large bandwidth fluctuations, such as Wireless LANs. Performance may be boosted by the adoption of application-aware/cross-layer schedulers devised to intelligently drop video data units (NALUs), so that i) decoding dependencies are preserved, and ii) the quality perceived by the end users is maximized. In this paper, we provide a theoretical formulation of a QoE utility-optimal cross-layer scheduling problem for H.264 SVC downlink delivery over WLANs. We show that, because of the unique characteristics of the WLAN MAC operation, this problem significantly differs from related approaches proposed for scheduled wireless technologies, especially when the WLAN carries background traffic in the uplink direction. From these theoretical insights, we derive, design, implement and experimentally assess a simple practical scheduling algorithm, whose performance is very close to the optimal solution.

“…Curiously, though retransmission strategies are identified as form of protection, no such strategy is cited. H.264/SVC was directly applied to fixed WiMAX accumulation-based congestion control for video-on-demand streaming in [10], in order to assess the capacity which was found to be about 20 mobile clients. In fact, the capacity may be larger as an early version of H.264/SVC was used with fine-grained scalability, which was later abandoned in favor of medium grained scalability (refer to Section II.B) for its coding efficiency.…”

“…In fact, the capacity may be larger as an early version of H.264/SVC was used with fine-grained scalability, which was later abandoned in favor of medium grained scalability (refer to Section II.B) for its coding efficiency. Various fairness metrics are compared in [10], which used standard Real-Time Transport Control Protocol (RTCP) feedback messages. Scalable video transmission can also utilize MIMO antennas [11] through parallel transmission of the layers and in [12] the layers were transmitted in parallel over multiple connections.…”

Abstract-As content management systems for IPTV reduce the latency between server and mobile device, real-time video streaming can tolerate single negative acknowledgments in the event of packet loss. However, the extent of packet retransmissions can be graduated and this paper proposes a scheme that is adaptive to whether network congestion or wireless channel degradation is most responsible for packet loss (or a mixture of both). By using the scalable variety of an H.264 codec, selective retransmission of base and enhancement layers is possible. The paper exhibits the trade-offs that arise as a result of adaptive wireless broadband video streaming. The scheme has been applied to a tandem network, i.e. a heterogeneous network with one part consisting of a wired IP network and the second part consisting of a broadband wireless access network.
