In preparation for Dolby Digital tranmissions later in the year, test transmissions have now being spotted by keen Digital Spy readers.

Test channel 'Test', which can be found at Frequency 11.508H, Symbol Rate 27500, FEC 2/3 currently is broadcasting 'The Matrix' in an audio only form.

However, using a Sky+ decoder connected to a suitable Dolby Digital based Amp reveals a Dolby Digital 5.1 soundtrack, and not the normal 48kHz PCM.

Note: In order to use this test you must set the optical out in the System setup to Dolby D.
