Simulation platform for multimedia broadcast over DVB-SH

Abstract

In this paper, we want to present a simulation platform for multimedia broadcast over DVB-SH. The platform has been designed and implemented within the context of the ESA study on "Scalable Video Coding Applications and Technologies for mobile satellite based hybrid networks". Its main features are realistic modeling of the multimedia encoding/decoding procedures done at the broadcasting headend and the mobile terminals, a detailed simulation of the DVB-SH link layer, and a representative emulation of the DVB-SH physical layer. With the help of this platform, important use cases for future DVB-SH systems, such as support of heterogeneous devices, graceful degradation of application quality across the coverage area, efficient statistical multiplexing of different services, etc. can be investigated in a straightforward and conclusive manner.

Packet level video quality evaluation of extensive H.264/AVC and SVC transmission simulation

“…Video data is packetized according to the RTP payload format [32] and a packet trace file is extracted that contains a textual description of the relevant characteristics of the RTP packets and the packetized video data. Further details on the rate-controlled encoding mechanism, especially in the context of a statistical multiplex scenario with several video streams, can be found in [16].…”

“…We analyze the presented approach in terms of accuracy and achievable runtime savings with an exemplary simulation of an IPTV service over a congested link. The presented mechanism has successfully been used in simulations within the context of SVC for mobile satellite transmission [16] and in investigations of different FEC schemes [17].…”
