A reliable delivery of HbbTV based Push-VoD services over DVB networks using RS codes

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 representation and give rise to three loss distributions that may result in poor Forward Error Correction (FEC) recovery capabilities. In this paper, we first analyze the behaviour of the FDP protocol system over a large variety of bursty erasure channels to characterize and to understand effectively the loss patterns seen within FDP protocol and at the AL-FEC input in order to be able to dimension the AL-FEC codes. Then, we propose and investigate a novel solution based on RS AL-FEC codes for the FDP protocol to increase the robustness of HbbTV based Push-VoD services delivery over DVB networks. This paper represents a first reference work for a reliable HbbTV based Push-VOD services delivery over burst-loss channels.
