Hbbtv

HbbTV is based on the CE-HTML standard, which supports JavaScript , CSS and DOM . In fact, this is a special website adapted for the TV, which can be called up to the screen. In addition, using the HbbTV platform, it is possible to create special online stores in which, for example, items of clothing or accessories of the main characters of blockbusters and popular TV shows will be available.

HbbTV was originally developed by broadcasters in order to be able to provide additional services regardless of the pay-TV operator, operators can also use HbbTV to their advantage and provide their subscribers with additional services without undue cost. Indeed, HbbTV provides all the basic APIs that a pay-TV operator may need to develop their own basic pay-per-click interactive services, including an interactive video mosaic, a video-on-demand portal, and an electronic program guide ( EPG ).

For equipment manufacturers, implementing HbbTV will be neither difficult nor expensive. HTML and JavaScript are currently very common. An example of an EPG and VOD portal with interactivity based on HbbTV is mature technology, and there are many open source browsers , such as WebKit , which the manufacturer of consoles can integrate in order to reduce the cost of their use. Equipment manufacturers are now just moving away from using closed operating systems to Linux, which allows them to use many free software components and applications for developing middleware .

From the point of view of pay-TV operators, the widespread use of standards by market players is a guarantee that the cost of set-top boxes will be reduced due to competition.

In 1998, in the UK , when launching digital terrestrial TV, the regulator chose the MHEG-5 standard for this purpose. The standard was intended to provide pseudo-interactive services - additional information on a television broadcast network without a reverse channel. The DVB consortium then tried to push forward the MHP standard, which provided more interactive features with applets written in the Java programming language. However, none of these technologies was widespread: MHEG-5 was based on a specific declarative language for describing the structure of content , which required special skills, and severely limited interactive capabilities, and MHP provided more opportunities for interactivity, but license acquisition costs and additional requirements to the user equipment on which the technology would work, and, as a result, the rise in price of this equipment became a serious obstacle to success.

Since the advent of Internet- connected televisions, proponents of these standards have tried to promote them by adding hybrid capabilities. But at the same time, a new initiative by broadcasters in France and Germany led to the emergence in 2009 of several working groups that wanted to develop a new specification based on open standards, that is, on the basis that led to the success of web technologies. Having abandoned the development of an optimal specification from the point of view of theory, which allows service providers to create all kinds of perfect options for interactive services, HbbTV developers went in a more practical way and preferred to create a solution that manufacturers of user devices - both set-top boxes and TVs - could easily implement.

The first channel on April 13 and 20, 2018, for the first time in the history of Russian television, used HbbTV technology on the live show “ Voice. Children . " Spectators were able to select candidates for mentors of the next season, evaluate the performance of the participants and the presenter’s jokes ^[1] . Since April 16, HbbTV has been introduced into the Let's Get Married program ^[2] . June 11, this feature was first used in the program “ Who wants to become a millionaire? ".
