geekPete: This is a request, and if it were to be a question, it would be along the lines of ...
Any chance you could broadcast the original pre-transmission resolution size of each program, within the EPG info?
This is so we can know if a program has been "upscaled" before transmission.
Why? ...
I generally re-encode programs that I have recorded using my PC-based PVR media server, because some of my viewing devices cannot handle fullHD resolution, nor some of the high-end "encoding options" in the stream, e.g. CABAC.
If this "upscaling" info was in the Program information, then if my conversion program could know that a 576 line source had been upscaled to 720 lines, I would program it to re-encode back down to 576, not the transmitted 720 line height, so it can be better viewed at no loss of quality on less powerful devices. Less importantly, it would also take up less hard drive space and use less network bandwidth when played over my wi-fi.
Thanks, :)
First off their are no 720p broadcasts now that TVNZ are 1080i.
And seondly the MHEG5 EPG says what shows are HD. Everything that's not labelled as HD is upscaled ON TV1, TV2 and TV3 so I can't see how your idea could actually work.
