3 Institut für Nachrichtentechnik U. Reimers Technische Universität Braunschweig The DVB Project has Defined Three Phases of Technical Development: In Phase 1 all technologies relevant to the broadcast channel via cable, MMDS, satellite and terrestrial transmitters have been developed and standardised. All relevant infrastucture standards have been devised. In Phase 2 all required return and interaction channels have been defined. Solutions exist for interaction channels via telephone, cordless telephone (DECT), mobile telephone (GSM), cable, LMDS, satellite. The standard for Data Broadcasting was created. In Phase 3 we are currently finalising the software system called Multimedia Home Platform Tell us what technical system you need: We probably have it already

7 Institut für Nachrichtentechnik U. Reimers Technische Universität Braunschweig Multimedia ?Home ! Platform Whatever you may think about the role of the DVB Project: we do not consider it our task to define a platform on which Multimedia devices can be stored in the home. DVB

8 Institut für Nachrichtentechnik U. Reimers Technische Universität Braunschweig The Multimedia Home Platform consists of a user terminal including all possible low- to high- functionality implementations, its associated peripherals, and the in-home digital network. The MHP solution encompasses the whole set of technologies necessary to implement the MHP including protocols, common languages (API), interfaces, and recommendations. The MHP supports several levels of interactive services / applications. These are defined as: Enhanced broadcasting (including local interactivity) Interactive broadcasting (using a return channel) Internet access

9 Institut für Nachrichtentechnik U. Reimers Technische Universität Braunschweig An Application Programming Interface (API) is used in a terminal device to implement certain functionalities that allow hardware-independent development of content and applications. It allows differentiation in terms of the capabilities of the end user platform. The Navigator is the basic user-interface of a terminal device used in the enhanced broadcasting mode. It is defined by the manufacturer of the terminal device. Each MHP provides a Navigator. The Electronic Program Guide (EPG) is the higher-level consumer navigation device in the enhanced broadcasting mode. It is an application which can be provided by different parties and may be delivered via the broadcast channel.

19 Institut für Nachrichtentechnik U. Reimers Technische Universität Braunschweig The Working Draft of the MHP In July 1999 the Steering Board of the DVB Project approved the “Working Draft of the MHP Specification” The “Working Draft” is the basis for the implementation of the Internationale Funkausstellung (IFA) 1999 in Berlin” For IFA 1999 several manufacturers (Nokia, Panasonic, Philips, Sony) have developed MHP receiver prototypes EPGs, games and other applications have been developed by several organisations The MHP concept has thus been demonstrated a few weeks ago A special exhibit at IBC 1999 was devoted to the MHP

24 Institut für Nachrichtentechnik U. Reimers Technische Universität Braunschweig Conclusion The MHP is an open software environment of high complexity The MHP specification will be complete by January 2000 First MHP receivers and applications will become available in the course of the year 2000 The development of the MHP is an extremely complicated process due to the mixture of technical, commercial and political problems The MHP development is a team effort. EACEM plays an important role as part of the team
