Background

The HbbTV specification was developed by industry leaders to effectively manage the rapidly increasing amount of available content targeted at today’s end consumer. It is based on elements of existing standards and web technologies including OIPF (Open IPTV Forum), CEA-2014 (CE-HTML), W3C (HTML etc.) and DVB Application Signalling Specification (ETSI TS 102 809). The diagram below shows the relationship between HbbTV and other existing standards.

The HbbTV specification does not depend on a particular broadcast link nor on a particular IP link. It may be applicable with either or connection, but gains most momentum in a connected environment to broadcast and broadband.

Important components provided by CEA-2014 (CE-HTML) for HbbTV are:

  • Definition of the application language (XHTML, CSS and JavaScript including AJAX)
  • Definition of how to embed non-linear A/V Content in an application
  • Definition of DOM event handling (eg key events)
  • Specification of still image formats

CEA-2014 is profiled through the OIPF Declarative Application Environment (DAE) specification. Other important components provided by the OIPF DAE specification are:

  • JavaScript APIs for applications running in a TV environment (eg channel change)
  • Definition of how to embed linear A/V content in an application

The DVB Application Signalling Specification (TS 102 809) provides the following components:

  • Application signalling
  • Application transport via broadcast or HTTP

The OIPF Media Formats specification defines the audio and video formats supported.

Errata 2 for the HbbTV Version 1.0
This errata document contains a set of identified and resolved errata to the HbbTV specification. These have been integrated with HbbTV 1.5 and the text of ETSI TS 102 796 V1.1.1 and the results are included in version 1.2.1. This fully replaces the former errata 1.

Version 1.5 of the HbbTV specification
Version 1.5 of the HbbTV specification introduces support for HTTP adaptive streaming (based on MPEG-DASH), 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 7-day electronic programme guides as HbbTV applications that can be deployed across all HbbTV receivers to provide a consistent user experience.
