About the project

The project aims at investigating the hybrid distribution of TV programs and services over Broadcast and Broadband networks. The technology used for the contents compression is the future video compression standard: High Efficient Video Codec (HEVC). The hybrid network and the HEVC standard will allow defining new added value services.

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. Architecture

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.

H2B2VS is divided into three technical work packages that will allow practical demonstrations, contributions to standardization bodies and scientific publications. These work packages are:

  • Hybrid Broadcast Broadband architecture and use case definition,
  • Impact of the hybrid distribution on future technologies,
  • Demonstrators.

Close cooperation between all these work packages is key to guarantee an optimized architecture as these topics have many interdependencies and this may enable the joint architecture optimization.

The following results are expected by the H2B2VS partners:

  • Implementation of HEVC Codecs and support for HEVC Scalability,
  • Adaptation of relevant standards to hybrid distribution: MPEG-DASH (Dynamic Adaptive Streaming over HTTP), MMT (MPEG Media Transport) and DVB signaling,
  • Development of a synchronization algorithm to synchronize Broadband & Broadcast networks,
  • Support for encryption and watermarking over hybrid networks,
  • Adaptation of CDN to allow hybrid distribution.

H2B2VS will explore two key factors that will impact significantly in the near future the multimedia contents delivery in Europe: the reduction of the bitrates in the transmissions and the hybrid distribution which is promising to be very popular.

The number of TV sets connected to Internet in 2012 is estimated to more than 210 millions around the world. The proportion of TV households with a connected set is expected to be more than 40% by 2016.

This kind of devices will allow the implementation of hybrid distribution without any additional cost for the users.
