Bandwidth questions - Internet and Cable TV

[moulsham]

Does anyone know whether the total bandwidth delivered by Telewest is in someway limited and if there is a trade off between cable TV and Internet?

I have the "10Meg" service on the Internet side and TVDrive on the TV Side. Now the 10 Meg has a theoretical d/l speed of (I think) 1280kb/s while I read somewhere else (http://forum.digitalspy.co.uk/board/...d.php?t=221219) that BBC1 and Sky1 have bitrates of 4.5Mbit/s (563kb/s) and 2.9Mbit/s (363 kb/s) respectively.

Assume the TV is broadcasting 1 Sky channel and the TV Drive is recording two BBC Channels the combined bits going into the TV side is 1,489 kb/s while the internet wants 1280kb/s giving a theoretical pipe into the house of 2,769kb/s. So how do these figures trade off between each other I wonder - does having the internet on and d/l "steal" bandwidth from the TV, or vice versa, or are they entirely separate?

Anyone any ideas? Or am I talking ******** here?

Yes it is limited, that limit varies depending on the capabilities of the networks in each area.

No the internet services don't take any bandwidth away from the TV when used, the two both have seperate quotas of bandwidth and cannot take bandwidth from each other.

http://www.digitalspy.co.uk/cable/howitworks/ is 'kinda' right.

You receive a lot more data than you are actually using at any one time.

As a quick rough and ready guesstimate it's not impossible for Telewest / NTL to send over 4Gbit/s to your home.
