The remit of the BBC HD channel is to offer a mixed-genre schedule of programming in high-definition (HD) format, most of which has been originated by the BBC's other television channels.
As BBC HD commissions only a very small proportion of its own output, its responsibility for contributing to the promotion of most of the BBC's public purposes relates in large part to ensuring that the relevance and appeal of the BBC's television programmes are maintained as consumer expectations for HD content grow.
Ultimately, BBC HD should help maintain reach to the programmes it shows and, in this respect, it should contribute to the BBC's overall ability to deliver its public purposes.
