Middleware software systems for operator function control are middleware systems in the field of television and broadcasting, which ensure the control of signal transmission from mass media (mainly television and radio) via the transmission network of digital television . Middleware software systems for operator function control are a management tool that has arisen as a result of the change from mass media to "mass communication media". Mass communication media are mass media with feedback , i. H. Formally there is the possibility for listeners, viewers or readers to exercise influence or to express their opinion.

Tasks of a middleware software system for operator function control

The tasks that a middleware software system takes over for operator function control have arisen taking into account various commercial, technical, social and political factors:

  • the development of accompanying mass media as an extended service for digital television and radio ( teletext , banner exchange )
  • the social need for the introduction of quasi-interactive services in digital television and radio, consisting of customer-adapted content from the Internet pages and blogs on the television screen. The display is implemented by the software components of the middleware software system for operator function control, which are integrated into the software of the digital television receivers . (TV browser )
  • The need to develop and integrate new technologies into civil warning and reporting systems in the event of an emergency .
  • commercial interests of advertisers and participants in the TV market in the mechanisms of opinion polls.
  • Interests of the traditional TV mass media in the design of commercial TV including pay TV (fee-based).

Functional examples in digital terrestrial television and radio broadcasts

  • Use of accompanying mass media : Electronic Program Guide , Teletext , group and individual dispatch of messages, use of digital signage on the screens of television participants
  • Use of a quasi-interactive access channel to the content of websites and blogs via an intuitive user interface ( menus of the receiver) and navigation control through the content with the traditional remote control
  • Distribution control of defined packages of digital TV and radio programs for broadcasts for certain regions or territories (including individual viewer programs - video on demand )
  • Use of control management for the automated transmission of regional program packages (advertising, local news, weather reports, etc.)
  • Used as a means of conducting electronic elections through television and telemetering of audience ratings
  • Remote software updates for digital receivers
  • Access limitation to the paid TV channels or authorization of subsidized digital receivers (using an access authorization system )

Implementation examples

Digital terrestrial television in Italy uses the Multimedia Home Platform system as a platform for implementing the e-management function.

The ISDB -T digital terrestrial television system in Japan uses the centralized middleware software system for operator function control for systems access control ( BCAS ), distribution of regional digital broadcast streams , and transmission of the electronic program guide.
