Freeview HD box spec published

The Digital TV Group has published a specification document which all boxes produced for the upcoming Freeview HD service must adhere to.

Among the requirements laid out in 'D Book 6' are broadband connectivity ready for as-yet unannounced interactive services and an automatic rescan feature in the event of new channels and services appearing. Also specified are standards for displaying MHEG interactive and subtitle services in HD.

Freeview HD is set to debut in the autumn in the Granada region offering three channels at launch from the BBC, ITV and Channel 4, broadcast using a combination of DVB-T2 and MPEG-4 compression.
