ITV HD only on Freesat?

Speculation is mounting that ITV’s new high definition service will be exclusive to Freesat.
Test transmissions for ITV HD are now being broadcast on Eurobird 1 at 11.428 GHz with horizontal polarisation, a symbol rate of 27500, and a service ID of 10510. However, the stream may not be viewed on Sky boxes, nor traditional free to air receivers, as the video stream is being broadcast as H.222 data rather than using the H.264/MPEG-4 AVC codec supported by such receivers and used by existing high definition services such as BBC HD.

Reports from those receiving digital satellite on their home computer have been able to view the stream after installing appropriate codecs. They report that the service information table for the 11.428 Horizontal transponder is carrying, in addition to the ITV HD stream, data services named “FreesatHome”, “FreesatCommonC”, “FreesatSSU”, and “FreesatOAD”.
