TDCOM said:I think you people may be getting confused. BT could allocate a seperate Virtual Channel for TV which would mean that its point to point in essence. It WILL NOT BE ROUTED OVER THE INTERNET. Routing that much traffic across the Internet would be a mean feat. Using a seperare VCI would solve alot of issues: but would mean that BT BROADBAND TV would be restrictive because it would not provide Internet integration.
Erwlas said:but when you hear that Norway, Sweden and Denmark all have 8mb connections available for what we pay for our 1mb it does make you think what BT are playing at. :shrug:

What??? on a 1gb / month cap
Or maybe that is why BT is looking at capping it's ADSL PC users cos it wants the bandwidth for itself ?
Hardcore Hustler said:then why do other countries provide 8, 10mbit connections?
Bob2002 said:Because they have well developed fibreoptic networks. :hrmph:
TDCOM said:What people fail to realise is that 8Mb connections do NOT perform at 8 Mbps because most Web Servers are throttled. I know for a fact that most Web Hosts throttle each website to 500Kbps to retain service levels. Also, broadband networks running at 8Mbps is seriously pushing the threshold. I honestly think that speeds in excess of 3 Mbps are just not needed YET. I am working for a company developing a high - speed switch which we hope will replace most ATM circuits at the core of the Internet.
Can I first say that teh CORE of the Internet DOES run on ATM. The conenctions between and American IPX's and U.K RUNS on ATM. It always has and probably will do.ProfPete said:And do you really believe that ATM is used on the core of the internet?! I doubt you'd find it anywhere near telehouse, except where BT are involved in supplying lines. Everyone else uses ethernet or DWDM, as do their own networks.
VoD requires at least 4mbps to attain a picture quality equivalent to digital TV. With HDTV on the way, this will require well over 10mbps per stream. Now, 2 people in the house watching more than one stream, you need more speed. Don't insult your own intelligence by pretending that higher speeds cannot be delivered are aren't needed/wanted. Fact of the matter is, we are very quickly falling behind other countries, who already have 10mbps for what we are paying for 512kbps...

... Not only is H.264/AVC very efficient, providing extremely high quality in smaller files, but H.264/AVC is also scalable, producing video for everything from 3G for mobile phones to High Definition (HD). H.264/AVC can create great-looking 3G mobile content at 50-160 Kbps, excellent Standard Definition (SD) video at 800-1500 Kbps, beautiful HD video (1280x720, 24p) at 5-7 Mbps and full HD video (1920x1080, 24p) at 7-9 Mbps. So at today’s SD DVD data rates, H.264/AVC can deliver full HD. In fact, H.264/AVC was ratified by the DVD Forum for inclusion in the next-generation HD DVD format.
