                        What is A Home Platform?

 Research &        The term home platform can encompass a number of devices;
Development
                   • set-top boxes                     • integrated receiver/decoders
                   • PC-based receivers                • distributed resources connected by a home network.

                   Initially it was assumed that digital TV receivers would contain a simple resident navigator relying
                   on basic Service Information (SI) provided in the broadcast stream. However, Interactive TV
                   applications and the Internet have emerged as important opportunities for broadcasters for which
                   provision must be made.
                       The DVB Multimedia Home Platform (MHP) is an open initiative to develop a standard for
                   interactive TV and multimedia services. The key requirement is an open specification and
                   interoperability of platforms and applications. The platform will support the migration of existing
                   services, be hardware independent and allow future evolution of services.


                         MHP Decisions

                   The DVB MHP will use the JAVA programming language, providing hardware independence, wide
                   support and an open development process backed by standardisation through ISO. Support for
                   existing applications will be provided by optional “plug-ins” and three profiles will be defined initially;

                             • Enhanced Broadcast        • Interactive access profile    • Internet access profile.


                              Status

                    The working draft of the enhanced broadcast profile is due by the end of May 1999 and it will be
                    launched, together with prototype demonstrations, at IFA 1999.
