Video Bandwidth Growth Forecast
19 Mar 2009 | 15.30 Europe/London
Analysys Mason have produced a report "Delivering High Quality Video Services Online" which forecasts substantial growth in the bandwidth required for delivery of video over broadband networks.
The report was commissioned and published by OFCOM as part of their technical research program.
At 122 pages the report covers the subject in some detail. In essence it concludes that under any realistic forecast the bandwidth required for video delivery is going to grow to between 300 and 2000 kbits/s per household in the busiest hour by 2018. For comparison the current bandwidth provision is around 25 kbits/s per user of which 20% is for video services.
The report predicts the extra costs of delivering this bandwidth and proposes a number of measures to contain the cost to a few £ per month per line - traffic management of P2P, use of multicast video broadcasting and content cacheing of video services in telephone exchanges.
It is assumed that the most constrained part of the network is the exchange backhaul to the core network, however it is possible that most BT Wholesale based IPStream customers will currently be limited by the capacity of their ISP connection to the core network. Analysys Mason did their analysis on the basis of 21CN systems as IPStream will be phased out over the next few years.

25kbit/s is nothing. I stream, download and upload a total of 5GB at least each day. I need alot more than what they are suggesting is the average. 2018 will be more like 2012, and it won't be 2000kbit/s; it will be something more in the region of 20000kbit/s to allow for HD content.
