Sony yesterday released their latest software (1.630SA) to enable BBC iPlayer on all their Freesat built-in Sony televisions. If you have one of these televisions, you should now be able to access BBC iPlayer from BBC1 by pressing the red button followed by code 5483. (instructions on how to connect your Sony television to the Internet to receive iPlayer can be found here)
Other manufacturers will be added as and when they have carried out the initial testing with the BBCi Tech Team. All Freesat HD receivers are expected to have BBC iPlayer enabled within the next few months.
