The integration of reliable Video-on-Demand (VoD) broadcasting schemes in mobile datacast systems, specifically in DVB-h, is studied and enhanced. Sophisticated VoD broadcasting schemes such as Harmonic Broadcasting (HB) allow receivers to tune into the ongoing transmission of a video-stream at arbitrary time, while still being able to receive the multimedia sequence from beginning to end, after short initial playout latency. In addition, we address service enhancements by using scalable video coding (SVC) to support heterogeneous receiver capabilities and receiving conditions as well as signal reception from multiple transmission sites. We present and discuss options for the integration of VoD broadcasting schemes in combination with fountain codes. Optimizations in parameter selection are introduced. A realistic protocol environment is only slightly modified to support our system concept. Simulation results show the benefits of the discussed VoD scheme compared to existing approaches if integrated in DVB-h.

In the nVoD (near Video-on-Demand) paradigm, video is distributed through broadcast channels with constrained bandwidth, yielding a bounded playback start time regardless of the number of users. In other words, there is unlimited scalability for low bandwidth cost, at the expense of a bounded start time. Thus, regarding bandwidth, nVoD schemas are well suited for wireless channels, but they do not address the problem of packet losses. Recent research based on digital fountains and the intrinsic redundancy of nVoD transmission provide correction capabilities with little or zero overhead, with negligible impact on bandwidth usage. This paper analyzes the most recent proposals and compares them in terms of error correction performance and memory consumption.

“…The clipcasting as presented has one drawback compared to live streaming as one has to wait quite long until the playout of the clip will start. For this purpose, virtual on-demand broadcasting schemes exist which allow this property: The most popular schemes are known asg Harmonic Broadcasting (HB) [26] and Pyramid Broadcasting (PB) [27]. The basic idea is to provide different segments of the content on different bearers.…”

The Scalable Video Coding (SVC) standard as an extension of H.264/AVC allows efficient, standard-based temporal, spatial, and quality scalability of video bit streams. Scalability of a video bit stream allows for media bit rate as well as for device capability adaptation. Moreover, adaptation of the bit rate of a video signal is a desirable key feature, if limitation in network resources, mostly characterized by throughput variations, varying delay or transmission errors, need to be considered. Typically, in mobile networks the throughput, delay and errors of a connection (link) depend on the current reception conditions, which are largely influenced by a number of physical factors. In order to cope with the typically varying characteristics of mobile communication channels in unicast, multicast, or broadcast services, different methods for increasing robustness and achieving quality of service are desirable. We will give an overview of SVC and its relation to mobile delivery methods. Furthermore, innovative use cases are introduced which apply SVC in mobile networks.
