Summary:
|
Increase of video traffic on the internet forces cable television operator too invest on additional facilities to accommodate increased IP traffic every year.
Most of the video traffic now is unicast which consumes much bandwidth, but is easy to use, and compatible with consumer devices such as smartphones and tablets. Since some of unicast connections carry linear programming such as news and sports, the traffic on the delivery network can be significantly reduced if such linear programs are transmitted as a multicast.
This work item defines the requirement of an IP delivery technology which makes use of multicast between headend and subscriber gateway but uses HTTP-based unicast connection between the gateway and consumer devices.
