Hybrid Broadcast Services using MPEG DASH

The emergence of new multimedia services such as super high definition or free viewpoint TV will put a very large bandwidth pressure on the broadcast networks. In order to offer these services while maintaining quality, service provider will have to use other delivery mechanisms. In this context, enhancing broadcast services with broadband media may be one key to low cost deployment of new services. This paper studies the problem of hybrid broadcast and broadband delivery of audio-visual content and reviews existing solutions. With the growing importance of HTTP streaming services, and the adoption of MPEG-DASH by the TV industry, a solution for hybrid broadcasting based on this standard is proposed. Implementation is presented and evaluated, and future work directions are discussed.
