Poor picture quality

[SteveWac]

When will sky decrease the amount of compression they apply to programs? 

Watching ITV 1 on stream results in lots of pixelated images (posterisation) especially in dark scenes, directly compared to ITV 1HD on Freeview, the sky picture quality is far worse, pixelation is barely noticeable on Freeview.

Hi @SteveWac 

It's not like for like comparison as one is broadcast and other is IPTV. Different technology with extra processing needed. If you feel it is unacceptable the best course of action would be to report it to sky (viewer relations email: [email protected]) and ITV.

Given that the community is customer helps customer no one where can advise on sky's plans or technical changes.

What are the video output settings on the puck? For the best quality stream of HD channels set the output to the native 1080i and let your TV do the upscale (assuming you have a 4K TV.)

When I had Sky Stream I found that the puck wasn't the best upscaler, my TV produced a better, sharper image if the puck was set to 1080i on HD channels.

Hi, 

Picture is set to 2160p.

It's not just ITV, the posterisation is bad on all channels, I think it's down to excessive signal compression so that sky can say only a 25mbps broadband connection is needed.

Try setting the puck to 1080i and see if your TV upscales native HD better than the puck.
