Today the Βι¶ΉΤΌΕΔ Red Button team is pleased to announce the open source release of the MHEG+ toolkit under the .
MHEG+ (pronounced: em-heg plus) is both a programming language and a suite of tools developed by the Βι¶ΉΤΌΕΔ for building interactive television services. If you have ever used the Freeview or Freesat Red Button services such as the interactive news & weather and even the CBeebies games and Formula 1 alternate commentary, you might be surprised to learn that you were using an MHEG+ application.
MHEG+ started its life in 2005 as a Βι¶ΉΤΌΕΔ Research & Development project aimed at creating a programming language more palatable and modern than its predecessor, . The '+' suffix in the MHEG+ name is meant to suggest it is a superior language to MHEG-5, often referred to as simply "MHEG".
Today MHEG+ is not just a programming language but also a comprehensive suite of tools for developing interactive television applications. The toolkit includes a compiler, debugger, emulator, automated testing tools and also a code editor that integrates with the .
The toolkit's emulator, named MHEG Player, emulates both Freeview and Freesat set-top boxes. It features an MHEG graphics engine, a virtual tuner (so users can 'virtually' switch from Βι¶ΉΤΌΕΔ One to Βι¶ΉΤΌΕΔ Radio 5 Live, say) and even a virtual remote control that doesn't get lost down the side of the sofa! The integrated debugger too is feature rich and can be used to debug both MHEG-5 and MHEG+ code.
Until today, MHEG+ was only available for use by Βι¶ΉΤΌΕΔ staff for the benefit of our own interactive television applications. But we think MHEG+ is too useful a tool to keep just to ourselves. MHEG+ is another example of the Βι¶ΉΤΌΕΔ's drive toward openness and demonstrates our eagerness to give something back to the technical community.
Further, we hope to encourage the community to get involved in MHEG+ and make it better. There are many ways to participate, from simply developing interactive applications (and possibly reporting bugs), to documentation writing and code contributions.
The MHEG+ source code can be browsed and downloaded at the . Here you can also find a forum for discussing MHEG+ and getting help.

Thanks.

It took a minor amount of deductive reasoning to figure out how to run the compiler and emulator/debugger, and that they weren't just Eclipse plug-ins (and that the compiler is a command-line tool -- not that I consider that to be a bad thing). However:
The toolkit includes a compiler, debugger, emulator, automated testing tools and also a code editor that integrates with the Eclipse IDE.
The automated testing tools and code editor don't *appear* to be in the release on Sourceforge -- are they MIA, not going to be released, or am I being dim? (the post certainly suggests they're meant to be there, but that could be me misinterpreting).
I noted also that the emulator doesn't seem to like loading compiled MHEG-5 files from an on-disk carousel where the source isn't available (or, in the case I was trying it with, was available but for some reason wasn't structured the way it was expecting).
Something along the lines of as a sample MHEG+ project would be good for illustrative purposes.

There is now a 'hello world' example.

Could you please raise your other concerns as bugs/feature requests on SourceForge. There are ways of achieving all of what you ask, but the detail is not appropraite for this blog post. Thanks
