Hi all, is it my imagination or has Sky bumped up the bandwidth on some channels, particularly the sports just recently? They seem easier to view in the last week or two...

Cheers Steve

Had a look at SS2 and the Rugby Channel. Seems they're both broadcasting at an average bitrate still about 3.5-4mb/s, so if it's been raised, it wouldn't be by much. Live NRL and Sevens on respective channels, so I guess if they'd pump it up, it'd be for that. Still pales to the 6mb/s or so that Freeview run at.

My impressions were that the league was looking better than usual, less smearing and pixellation? I did think that the Sevens had a pretty bad quality from source? Very grainy.

Sky might have installed a newer generation of decoder which would provide a noticable difference in picture quality.

perhaps that is the case, purely in terms of bitrates, not much has changed.

Agreed about the Sevens, it looked rubbish on TVNZ (DVB-T and DVB-S) and Sky (Rugby Channel and SS1)

Decoder, or Encoder, if its Encoders, Sky upgraded all their encoders about 18-24months ago to the lattest Tanberg E5770 encoders, I seem to remember they got 80 encoders and payed around US$4m for them. So doubt they would be upgrading hardware, maybe firmware or general encoding bitrate changes.

They could be cleaning things up as they move to their new digital production/presentation suites as part of Mt Wellingtons major upgrade.

It's a bit too early to see picture improvements from the transmission chain upgrades at SKY and there haven't been any significant changes (to my knowledge) to the encoders or bitrates. I was told that the quality of League material brought in from Australia has improved recently due to equipment upgrades there. Poor quality material or material dirtied-up in processing is a real problem as, not only does it look bad, but it sucks bandwidth from other channels to encode its noise.
