Abstract
Hybrid broadcast broadband TV is a technique providing Push-VoD services over an interactive hybrid TV. These services are broadcast using a file delivery protocol (FDP), which includes different coding strategies to ensure reliable delivery. This protocol is characterized by three levels of data representation giving rise to segmentation of packet losses, which may result in poor recovery capabilities. This paper provides a first thorough investigation of the coding FDP framework for reliable delivery of Push-VoD service over DVB networks. We propose Markov modeling for characterizing inter-layer loss propagation within FDP on a wide variety of burst erasure channels. Based on this analytical analysis and a simulation study, we determine the possible recovering areas and the accurate loss measurements within FDP. The latter is then used to effectively investigate and configure the different coding strategies provided within FDP. In addition, we present a suitable recovering strategy for FDP, which guarantees transmission robustness against the broadcast network impairments.
