"New" ITV1 HD channel
I mean the ads with Ant & Dec.
Are ITV advertising this because of Freeview HD or will more shows be added to the exsisting service on Freesat?

Mostly, because it's now much more widely available; it's on all the UK digital platforms, whereas before it was, nominally at least, a Freesat exclusive

6 months ago the Part-Time ITV HD bit rate was quoted in forums as over 10.5 mbps ie better than the then BBC HD..
Now that ITV HD is with us .. As an old Cynic,, could i ask.. Why have i not heard that one is better than the other? For that matter anyone know the current rates for both please? |

Itv has a little more bitrate for video but less for audio which is what I posted |

ITV1 HD and BBC HD are equal for stereo with 192kbps AC3, but BBC only uses 384kbps for 5.1, so in theory you are getting less bits, 76.8 vs 96kbps per channel with stereo (or less if you count the .1 as a channel).
In practice the source material has much more effect on picture quality there's good and bad HD pictures on both channels. |
