The HbbTV (Hybrid Broadcast Broadband TV) consortium has announced the publication of version 1.5 of its hybrid TV specification. Building on existing standards and web technologies, the HbbTV specification provides the features and functionality required to deliver feature rich broadcast and internet TV services.
Version 1.5 of the HbbTV specification notably introduces support for HTTP adaptive streaming based on the recently published MPEG-DASH specification, improving the perceived quality of video presentation on busy or slow Internet connections. It also enables content providers to protect DASH delivered content with potentially multiple DRM technologies based on the MPEG CENC specification, improving efficiency in markets where more than one DRM technology will be used. Version 1.5 significantly enhances access to broadcast TV schedule information, enabling operators to produce full seven-day electronic programme guides as HbbTV applications that can be deployed across all HbbTV receivers to provide a consistent user experience. The latest advances are based on activity within the HD Forum in France as part of the development of the TNT 2.0 specification
