An updated version of the HbbTV specification was approved by ETSI as ETSI TS 102 796 v1.2.1 in November 2012.
Download this update of the HbbTV specification.

This version is based on 3 documents;

the original TS 102 796 V1.1.1 from ETSI
errata 2 to TS 102 796 V1.1.1 from HbbTV
HbbTV specification 1.5

References to these 3 separate documents are below (see section "Historical Documents").
They should not be used any longer.


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.
