Compare RTÉ pictures on MPEG2/4

Good chance to compare RTÉ PQ between MPEG 2 (Freeview) and Saorview MPEG 4, for those who have both. The BBC's Parliament channel is showing RTÉ's election results coverage for most of the day on Saturday.

Better comparison is RTE on Sky vs RTE on Saorview.

You do realise that Picture Quality is independent of MPEG2 vs MPEG4 and depends on
1) Bit rate the Broadcast decides to use.
2) How good the quality is.

The point is that if you adjust the bitrate on MPEG4 so you can't tell the difference in qualitity with the MPEG2, the MPEG4 will use less bitrate.

Sorry watty, just thought it might be amusing to look at same pictures over both systems

Yes, it might. But it doesn't tell you anything!

Watched a repeat of the Pat Kenny 5 way debate on BBC Parliament the other night. Picture quality was decidedly ropey compared to normal BBC P output.

I wonder what source the Beeb had for its footage of the 5 way debate. It may have been re-encoded MPEG2 from perhaps the Astra 2 source, though I would assume this is unlikely.

Come to think of it, it did have a look of "off-air" about it. The standard DOG and even the ad breaks which had been crudely edited out.
