Interactive Services

The bmt’s interactive services for broadcasting encompass products where the user must also play an active role. The bmt can develop custom services/applications harmonized precisely to the needs of the application, and thus optimized in terms of performance and stability.

The bmt also draws on its own experience to develop for all current systems, such as HbbTV, iOS and Android.

Current Projects

Local TV portal

The Local TV portal comprises a still image channel and an HbbTV application. It is intended to make it easier to find local TV programming.

The still image channel is fed by satellite and shows all available local TV programming, including the logo, program name, ID and transponder slot (frequency). Satellite receiver users can then find programs on their own and bookmark their favorite program slots.

The HbbTV application can be received via DVB-T and satellite on Smart-TV receivers (HbbTV). The selection of local TV programming is collated into lists (by federal state) and program (broadcaster name), and is supported through maps and logos. If a given program is available, selecting it leads to an automatic jump to that live satellite signal or to the broadcaster’s specific HbbTV application with a media library or similar.

Prior development projects

The BR Radio App (iOS) and BR Rundschau App (Android) were developed for BR. The bmt was commissioned by the BLM to develop the BLM local radio (iOS) app, an iPhone application for local Bavarian radio programming.

The DynSI (Dynamic Service Information) system developed by the bmt processes topical content bundled with the broadcast signal and makes it available for transmission. This is handled based on the so-called Service Information (SI), in this case specified for Digital Video Broadcasting (DVB).

Modular radio app

This new product from the bmt involves an iOS and Android radio app featuring a modular construction. Select your preferred options and offer your listeners and users the latest app technology in your corporate design.

Select from the options

– Notifications
– Image/email/voice to studio

– Current song/playlist
– Banner ads
– Alarm clock function

Or tell us your ideas and we’ll integrate them.

The bmt is also involved in the field of digital radio (such as the “DAB-Toolbox” and “Datendienst goes Handy”) and mobile broadcasting with interactive services (such as with the aid of Java or MPEG4-BIFS).


Given the relatively short usage times, users seeking mobile access to TV content on portable receivers need quick access to interesting, highly meaningful information. There are two ways to achieve this: classic linear programming; or a system to save segments from the on-going program to allow on-demand viewing. Tagging involves the marking of individual segments of an audio or video stream by the program broadcasters, allowing for targeted recording based on category and simple call up based on meta-information bundled with the broadcast. A demo application developed by the bmt shows how tagging works on mobiles, and clarifies the potential applications of tagging. Program segments are sorted by category and can be selected and viewed based on a brief description of the content. The time for recording and the program broadcaster’s logo are also displayed on each segment. Once a viewer composes a playlist of desired segments, those segments can then be collated into a virtual program — ordered to the viewer’s preference — for future viewing.

Interactive Applications (MPEG4-BIFS, Java)

BIFS stands for Binary Format for Scenes, a descriptive language contained within MPEG-4 used for interactive multimedia content. When working with DMB, BIFS offers the opportunity for supplemental services such as the ordering of merchandise or a news ticker to be included with a video service.
