"The BBC is extending its Backstage project to include interactive television. The aim is to provide support for third-party developers. The initiative, announced at the Edinburgh International Television Festival, will initially focus on the MHEG standard used on the Freeview digital terrestrial television platform in the United Kingdom The BBC is now planning to extend the initiative to include interactive television. The aim is to expand the talent pool of developers for interactive television by providing simple tutorials, code examples and releasing internal tools and tests. The initial focus will be on MHEG. Some might argue that this should have been done years ago, although they might question whether MHEG is still the best standard to pursue. While there is comparatively little commercial interest in developing for the MHEG platform, it falls mainly to the BBC to maintain support for the standard. This will be particularly important if MHEG is also adopted for the proposed Freesat service, as seems possible. MHEG could be used to support the EPG application for such a service"
