Expanding Window Fountain Coded Scalable Video in Broadcasting

Kristian Nybom, Stefan Grönroos, Jerker Björkqvist, Expanding Window Fountain Coded Scalable Video in Broadcasting. In: IEEE International Conference on Multimedia & Expo, 2010.

Abstract:

The Expanding Window Fountain (EWF) codes are a new class of rateless codes, providing
Unequal Error Protection (UEP). These codes are especially suitable for Scalable Video
Coding (SVC) having unequally important data layers. In this paper, we show that EWF
codes are usable for transmitting scalable video in mobile channels. We characterize the
channel by field measurements in a DVB-H network. We tune the EWF code parameters to
achieve real-time transmissions of SVC video. Moreover, we use a code symbol header for
the EWF codes, which is also used in the IPDC over DVB-H standard, such that the codes
can be efficiently used without the need for excessive packet header redundancy. We show
that if some latency in the video is acceptable, then EWF codes can be used for real-time
transmissions.
