context: Virgin Media (re-branded in 2007 from NTL:Telewest) started to offer a high-definition television (HDTV) capable set top box, although from 30 November 2006 until 30 July 2009 it only carried one linear HD channel, BBC HD, after the conclusion of the ITV HD trial. Virgin Media has claimed that other HD channels were "locked up" or otherwise withheld from their platform, although Virgin Media did in fact have an option to carry Channel 4 HD in the future. Nonetheless, the linear channels were not offered, Virgin Media instead concentrating on its Video On Demand service to carry a modest selection of HD content. Virgin Media has nevertheless made a number of statements over the years, suggesting that more linear HD channels are on the way.
question: what was the name of the other HD channel Virgin media could carry in the future?
