Following on from its approval of HDR last week (DVB Approves HDR, HFR and NGA for Broadcast), the DVB Steering Board has approved the Commercial Requirements for Adaptive Bit Rate Streaming Multicast, the stage that precedes the development of a technical specification. The specification is intended to provide a way to transmit linear video at scale across IP-based networks. The aim is to be able to support OTT multiscreen services.
Thierry Fautier of the Ad Hoc Sub-Group of CM-AVC, which was tasked with defining the Commercial Requirements for ABR Multicast, said “Adaptive bitrate streaming delivered over the top on managed networks is based on unicast technology, making it difficult to scale for live applications. To resolve this issue, the DVB has decided to develop a specification that will enable ABR multicast distribution via any bidirectional IP network, including telco, cable, and mobile.”
