| Broadcast networks and the current video compression standards 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 is an obstacle to adding new services associated with the broadcast programs.The lack of interactivity on this kind of networks is also an important problem for the development of new services. Broadband networks have also a limited bandwidth and suffer from difficulties to guarantee the Quality of Service.However, the interaction provided by these networks is necessary for the implementation of added-value services. H2B2VS proposes a solution to cope with the problem of limited bandwidth on both networks by using the Broadcast network to transmit the main information and the Broadband network to transmit the additional information which can even be interactive. HEVC will also be used to reduce the required bit rate.One of the major technical 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. Synchronization between the two networks will thus be a key issue to be solved by the project.New services will be implemented using the results obtained in the H2B2VS project. Among them, we can mention broadcasting a program on the terrestrial network and sending its complementary information for Ultra-HD over the IP network, or using the Broadband network to carry out the sign language translation of a broadcast program to help deaf people. | |
