My TV is dead so I haven't been watching the WC but given how important the last game for the AW was I decided to record it anyway using gbpvr and DVB-T. Ironic I can record but can't watch :-(
Watching the recording later on a 1080P projector and 100" screen I noticed the following.
The PQ was pretty good - certainly very capable of being called HD and there were no artifacts that I could see from excessive compression and you would see those on this size screen.
Audio was AAC. Now this isn't surprisinging give that's TVNZ's standard but since AAC-HE is not that widely used around the world, I would have been surprised had the host broadcaster provided audio in this format - most likely DD 5.1 for their HD feed. That implies TVNZ did a real time encode of the signal which seems like a silly thing to do. If folks remember the Olympics, TVNZ send over a 5.1 feed since that is the audio feed coming from Beijing.
For the people with MySKY HDI did you guys get a 5.1 feed?
