HEVC hybrid broadcast broadband video services
H2B2VS aims at investigating the hybrid distribution of TV programs and services over heterogeneous networks: Broadcast and Broadband networks, using the future video compression standard: HEVC.
This standard, still under construction, will have difficulty to be commercially deployed if new video services or new video formats are not deployed simultaneously.
However, the Broadcast networks have a limited capacity that does not allow considering easily the broadcasting of bandwidth-demanding new video formats such as 3D or Ultra-HD. Their limited capacity will also be an obstacle to adding new services associated with the broadcast programs.
Using the broadband network to carry additional information in these programs is a solution. One can consider the following examples: Broadcasting a program on the terrestrial network and sending its complement to 3D or 4K over the IP network, or using the Broadband network to carry sign language translation of a broadcast programme to help deaf people.
One of the major challenges the project will have to face will be the difference in the Quality of Service encountered on these two types of networks. On Broadcast networks, all parameters are fully controlled by the operator. In contrast, on Broadband networks based on IP technology, parameters such as delay or jitter are not fully mastered.
