Hybrid Broadcast Broadband TV
Hybrid Broadcast Broadband TV (HbbTV) is both an industry standard (ETSI TS 102 796) and promotional initiative for hybrid digital TV to harmonise the broadcast, IPTV, and broadband delivery of entertainment to the end consumer through connected TVs (Smart TVs) and set-top boxes. The HbbTV consortium, regrouping digital broadcasting and Internet industry companies, is establishing a standard for the delivery of broadcast TV and broadband TV to the home, through a single user interface, creating an open platform as an alternative to proprietary technologies. Products and services using the HbbTV standard can operate over different broadcasting technologies, such as satellite, cable, or terrestrial networks.
HbbTV is the association of two projects born in February 2009, with the French H4TV project and the German HTML profil project.
HbbTV can show digital television content from a number of different sources including traditional broadcast TV, internet, and connected devices in the home. To watch hybrid digital TV, consumers will need a hybrid IPTV set-top box with a range of input connectors, including Ethernet as well as at least one tuner for receiving broadcast TV signals. The tuner in a hybrid set-top box can be digital terrestrial (DVB-T, DVB-T2 ), digital cable (DVB-C, DVB-C2) and digital satellite (DVB-S, DVB-S2).
HbbTV was first demonstrated in 2009, in France by France Télévisions and two developers of Set Top Box technologies, Inverto Digital Labs of Luxembourg, and Pleyo of France, for the Roland Garros tennis sport event on a DTT transmission and an IP connection and in Germany using the Astra satellite at 19.2° east during the IFA and IBC exhibitions.
The reception of digital TV and, in particular, high definition broadcasting in the home is well established across Europe. Internet TV and the delivery of multimedia content to the home user via the Internet are also becoming increasingly common, although such content is often viewed on a PC or fed to a TV screen from a PC via a media player connected to a home network.
HbbTV is intended to extend the reach of multimedia content directly to the television set in a seamless, viewer-friendly manner and to enable the TV viewer to more conveniently access both broadcast digital content (especially HD) and Internet multimedia content (including Internet TV and IPTV) on a TV set using a single remote control/box and a single on-screen interface.
Designing and developing a hybrid set-top box is a complex challenge, and not simply a matter of integrating the different input sources. The consumer experience must be optimized so that all media sources are integrated seamlessly and accessible through a single Electronic Programme Guide, and this requires very advanced software programming.
Applications and Consumer Products
Services delivered through HbbTV include enhanced teletext, catch-up services, video-on-demand, EPG, interactive advertising, personalisation, voting, games, social networking, and other multimedia applications.
At the May 2010 Broadcast and Beyond Conference in London, Thomas Wrede, VP Product Management Media at SES, said that he expected HbbTV devices to be launched commercially from June 2010 with a consumer market introduction at the IFA consumer electronics trade fair in Berlin in September 2010. Wrede also noted that Humax and Videoweb both had conformant products and that at the recent ANGA Cable trade fair in Cologne, 12 manufacturers exhibited HbbTV devices, with another six working on product introduction.
HbbTV devices enables consumers to view all of these advanced services on their flat screen TV, via a single device. In addition to a broader range of content from TV providers – ranging from traditional broadcast TV, video on-demand and catch-up TV services, like BBC iPlayer – hybrid digital TV also provides consumers with access to user-generated content [either stored on an external hard drive, or cloud storage, and to a range of advanced interactive services and Internet applications.
Hybrid set-top boxes are increasingly commonplace amongst pay-TV operators, as they look to meet the changing media consumption trends for more video content, advanced interactivity and internet applications, like social networking. Operators like n, a division of ITI Neovision, in Poland and Telekom Austria are two of the leaders in the deployment of hybrid set-top boxes. The 2010 IPTV World Forum Awards recognized a hybrid solution as the best interactive TV service/application: the solution, developed by Advanced Digital Broadcast, is the first three-way hybrid platform that enables content delivered via Satellite, Terrestrial and Ethernet networks to be viewed on a television.
The HbbTV consortium has over 50 supporting members from the CE and Broadcast industries, including:
- Standardisation & research bodies: Digital TV Group, EBU, Fraunhofer IIS, IRT, TNO

The full list of companies officially supporting the initiative is provided on the HbbTV website.
The HbbTV consortium steering group members are: Abertis, Astra, Ant Software Ltd, Digital TV Labs, European Broadcasting Union, France Télévisions, IRT, OpenTV, Opera, RTL, Samsung, Sony, TF1, TP Vision
In May 2011, in an email sent on behalf of the HbbTV Consortium steering group, supporters of the consortium were invited to become full members. The transitional arrangements towards the opening of membership would involve withdrawal of a number of privileges, including participation in meetings and contribution to further versions of the specification, from supporters that did not sign up. The cost of membership is around €7,000 for the first year.
As well as helping consumers/viewers, the introduction of the HbbTV standard is of benefit to both equipment manufacturers and content providers who at the moment have to produce hardware or content specific to each country to meet the de facto standard in that country. The establishment of a unified European HbbTV standard means "content owners and application developers can write once and deploy to many countries".
The standard specification has been submitted by the end of November 2009 to ETSI, who published it under reference ETSI TS 102 796 in June 2010. There is an accompanying Test Suite that provides a set of test material to test HbbTV device implementations, suitable for manufacturers of devices, including software and hardware components that implement the HbbTV specification (ETSI TS 102 796 v1.1.1). In November 2012 Digital TV Labs became the first Registered Test Centre.
The applications for HbbTV are HTML based, but utilise only a sub-set of standard web standards, developers have to use specialist validation tools.
Several countries worldwide, and in Europe in particular, have adopted the HbbTV standard and/or operated HbbTV services and trials. As at December 2011, HbbTV services are in regular operation in France, Germany and Spain, with announcements of adoption in Austria, Czech Republic, Denmark, Netherlands, Poland, Switzerland, Turkey, and trials in Australia, China, Japan, and the US.
In 2010 German broadcaster RTL Television introduced a new information service, HD Text, making use of HbbTV and the CE-HTML user interface language and in 2012 launched an online music video service (Clipfish Music) on its HbbTV portal allowing access to TV viewers.
In 2011 the Dutch national public networks, Nederland 1, 2, and 3 began broadcasting HbbTV "red button" applications including an program guide and catch-up TV instead of developing separate apps for particular platforms.
In France, the government-owned public broadcaster, France Télévisions selected HbbTV for its interactive news, sports and weather service, and plans to add catch-up TV and social media sharing capability. International French news channel France 24 has announced that it will launch an HbbTV interactive news service in 2012 via the Astra 19.2°E satellites, with support from Orange and SES.
In November 2011 Spain’s Ministry of Industry approved a document signed by 54 companies adopting the HbbTV standard and broadcasters, Mediaset España, Canal+ and Telefónica have run pilot services.
The first tests of HbbTV services in Poland were started by TVN in March 2012.
In the UK, most broadcasters have not adopted the HbbTV standard but Freesat, the free-to-air satellite TV service broadcast via Astra 28.2°E, has revealed that the second generation "G2" specification for Freesat receivers will use HbbTV, to take advantage of the digital TV chipsets being developed for that standard (but retaining MHEG-5 compatibility of the first generation Freesat receivers). While the Digital TV Group approved D-book 7, a detailed interoperability specification between digital terrestrial television and HbbTV based products and services.
In Nordic region (Denmark, Finland, Iceland, Norway and Sweden including Ireland) the NorDig standardization forum has adopted the HbbTV specification which replaces DVB-MHP as the common API for hybrid digital receivers. In Finland the national HDTV Forum will adopt the NorDig Unified Specification for Hybrid Services. The members of HDTV Forum see the HbbTV specification having a wide market acceptance supporting wide range of TV applications and new hybrid services. First HbbTV compatible receivers are expected to be available for consumers before Summer 2012.
HbbTV also caught interest in the US, Argentina, Australia, Japan, China (which is conducting a trial) and Malaysia (where DVB-T2 broadcasting will soon start).
HbbTV set-top boxes
Since the beginning of 2010 a new generation of advanced HbbTV IPTV set-top box has emerged in the UK with the advent of DVB-T2  services. DVB-T2 tuners enable the reception of free-to-air terrestrial high definition programmes to be received in around twelve areas of the UK.
High definition digital terrestrial services have encouraged a range of device manufacturers to launch new hybrid set-top boxes for the UK consumer retail market. Some of these companies have launched devices that, in addition to allowing traditional broadcast and IP-delivered services to be received, have an integrated smart-card slot that allows consumers to receive encrypted Premium television services including sports and movies.
Such boxes enable the aggregation of traditional linear TV broadcasts with video delivered via both managed (cable) and unmanaged IP networks (the internet). This allows viewers to view broadcast television and internet video on their flat screen TVs, alongside advanced interactive services, such as Video on demand, internet browsing and time-shifted TV.
A hybrid IPTV platform helps operators increase average revenue per user (ARPU), whilst eliminating expensive duplication in network infrastructure investment. IPTV customer-premises equipment (CPE) allows pay TV operators to deploy home entertainment, with video telephony, surveillance, gaming, shopping, e-government and interactive services amongst the service mix that can be offered.
OpenHbb is a collaborative project funded by the French government (DGCIS), the Pays de la Loire and Ile de France regions, and the Conseil Général des Hauts de Seine (council for the département of Hauts de Seine) as part of the Images & Réseaux and Cap Digital competitiveness clusters.
