Analytical modeling of losses in FDP protocol of HbbTV based push-VOD services over DVB networks

Abstract : Hybrid broadcast broadband TV (HbbTV) is a technique providing Push-VOD services over an interactive hybrid TV. These services are broadcast using File Delivery Protocol (FDP) characterized by three levels of data represen- tation and give rise to three loss distribution that may result in QoS degradation and poor Forward Error Correction (FEC) recovery capabilities (if FEC is used within FDP). In this paper, we address for the first time the issue of depth analysis of loss propagation within FDP system to understand and foretell the perceptual VOD quality and the FEC behavior at receiver side. We first propose analytical models based on Markov chains to accurately predict the losses and the burstiness along the FDP system levels allowing to avoid the analysis by experimental NP-hard method. Then, based on simulation, we validate the proposed models for all tested average loss rates and average burst loss lengths. Finally, we show that the proposed Markov models allow to guess ahead effectively VOD QoS and FEC behavior. © 2017 IEEE.
