Less bits, but the amount of efficiency gain with the newer codecs is greater, so it will look and sound better.”

Lol so its like an MPEG2 encoded channel at 2.4Mbps!

Although Film4+1 is lower resolution than Film4, so it should look worse than that...

It's not MPEG4, it's AVC. MPEG4 is a generic term covering several codecs (over more than one generation).

Not that much to do with the native resolution, the quality of the TV is more important and a 1320x768 may knock spots of a 1920x1080 but the screen size is the most important thing when judging whether HD will improve the picture or not. Actually an HD transmission will usually look better even when viewing via SCART because of the better compression.

Thanks, AngusMast. I rarely watch any SD Freeview channels on my big Samsung as the pictures are all generally lousy but Film4+1 definitely is slightly better. (The Freesat SD pics on it are streets ahead. HD is good on either). I hope C4 get out of their Sky tie-up so we can have Film4 HD on Freeview

A luxury in 2014!

Resolution isn't everything.

I would rather watch a 'soft', but relatively artefact-free picture than a 'sharper' one with ringing and blocking everywhere.

The T2 SD images provide that.

Wow, to bring you the latest on the null packets transmitted at night (01:26 GMT) for BBC B multiplex is reportedly at 23.2Mbps, with all channels sampled, BBC One HD, BBC Two HD, BBC Three HD, ITV HD, Channel 4 HD and Film4+1. Seemingly BBC Four HD/Cbeebies HD and BBC News HD could move from COM7 mux to BBC B mux?

However, the mux was transmitting 9.6Mbps of null packets earlier on Friday (around 14:30 GMT)

Just by the screencaps, I would say the COM7 signal isn't the strongest wherever the receiver is. When visiting the website in the past, I've seen that particular mux completely drop out sometimes, so I would take the figures with a pinch of salt (unless someone on the forum verifies of course).

As you note in your post, you have to look at the bigger picture. Even if last night's figure was accurate, the peaks are probably more important - about 9Mbps spare. More likely space for a single HD channel. (so status quo really)
