    On the heels of defining a pathway for Ultra HD development, the Digital Video Broadcasting (DVB) consortium is now focusing on adaptive bit rate (ABR) streaming for live applications multicast techniques over IP networks.

    DVB UHD The DVB believes that in today’s environment operators and content providers are under increasing demand to deliver video content anytime, anywhere, over any network to any device.

    As a response, the consortium says that the purpose of the work with ABR is to help meet what it regards as growing consumer demand for superior quality over-the-top (OTT) multiscreen services. After considering the commercial requirements for ABR multicast, the DVB will commit a technical module to produce a specification, the scope of which is intended pave the way to providing a harmonised solution to the problem of transmitting linear video at scale across IP-based networks.

    Recognising current use cases, the specification will apply to both managed and unmanaged networks. It will aim to use existing media workflows and transmission infrastructure while retaining support for security and stream manipulation features.

    “The broadcast industry faces the challenges of serving multiple devices across broadcast and broadband networks,” said DVB chairman Peter MacAvock, commenting on the new work item. "It’s essential to have a good set of tools to help, and DVB’s work in adaptive bitrate streaming continues to be a cornerstone of industry efforts in this area.”

    Thierry Fautier of the ad hoc sub-group of CM-AVC, which is tasked with defining the commercial requirements for ABR Multicast, added: “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.”
