MHEG-5 Profiles

MHEG-5 profiles form the framework specification for creation of MHEG-5 based technology and deployment of MHEG-5 based services on a selected platform. Profiles define various mandatory and optional features required to successfully deploy interactive services on a platform.

Features specified within a typical MHEG-5 profile include:

the user experience

MHEG-5 engine presentation/graphics models

fonts & language character sets

extensions/modifications to the MHEG specification

receiver requirements

return channel mechanisms

object carousel profile

application authoring rules & guidelines

The profile forms the basis for specification and development of conformance test suites leading to better end-to-end interoperability for all stakeholders.

MHEG-5 Technology

MHEG-5 technology is currently primarily driven by the UK Freeview (and UK Freesat) objectives. As custodians of the UK Profile, the UK Digital TV Group (DTG) with it's stakeholder members consisting of manufacturers, broadcasters and technology providers, plays a key role in driving the specification and development of new requirements for MHEG-5 based products and services.

Please refer to the MHEG-5 Profile & Technology Roadmap diagram below which illustrates ongoing development of various country specific requirements and technology enhancements (and how the various profiles derive and relate to each other).
