Sky TV - the technology

[Andehh]

Just noticed that one of my recorded programmes is 3gb, for an hour long episode. With sky TV getting me these programmes via the satellite are they really beaming me 3gb/hour based on my HD choice? So watching a few hours an evening very quickly adds up, throw in a few million other people makes that an insane amount of data, all from a few satellites.

What am I missing here? Codecs or encoding that reduces the "beamed" size?

[Andehh]

Thanks, im intrigued now. So the hour long programme recorded was 3gb, so is that satellite broadcasting each channel (HD for example...) at a rate of 3ish gb an hour? Multiplied by 150(ish) channels?

[Andehh]

Many thanks Yonox, very interesting (I'm an engineer, so I'm sad like that!) & just the right level of detail!

How did you calculate the 3GB bit?

It came up in the menu when I was selecting stuff to watch, cant remember off the top of my head which one but I think It was in a folder of the series & when highlighting each episode it appeared below the image in top right hand corner? Something like that.
