The DVB Steering Board, part of the organisation who are responsible for maintaining digital TV standards has approved a new DVB-I specification, that aims to ensure that linear television delivered over the internet is as user-friendly and robust as a traditional broadcast television experience. It offers the possibility for linear television services to be delivered to any device with a suitable internet connection and media player, including TV sets, smartphones, tablets and media streaming devices.
The DVB-I specification defines DVB-I Service Lists, a means for internet-connected devices to find curated sets of linear television services that may be delivered through broadband or broadcast mechanisms. It also defines the methods to retrieve electronic programme data for those services, which can be integrated into a single coherent offering that is accessed through a consistent user interface.
Also related to DVB-I is the forthcoming DVB specification for multicast adaptive bit rate streaming (DVB-mABR), targeting situations where the same linear content is simultaneously delivered over managed broadband networks to multiple receivers. Supporting the mass market scalability of internet-delivered linear television, DVB-mABR will reduce the overall network load.
DVB Chair Peter MacAvock said:
In developing an internet-centric solution for linear television services, we are providing the industry with a crucial missing piece that raises internet-based delivery to the same level in the DVB ecosystem as RF-based content delivery. With these building blocks, addressing the discovery of DVB-I services and the delivery of programme metadata, DVB offers broadcasters and operators an exciting new deployment option.
