Oh, it uses bandwidth. Jadoo is not IPTV, but rather internet TV.
The difference? One uses the internet to get content, the other uses internet protocols. Sounds the same? kinda, sorta, not really.
Here's what I mean:
Unless you're with a company that offers true IPTV, like telus, it uses internet bandwidth.
The TV packets are routed over a separate 'connection' than your internet transfer.
But it's still over the same pipe.
True IPTV has the benefit of multicast - one packet is sent to every end device, only using x internal bandwidth.
With internet video as it is now, usually it's on-demand. So you initiate a connection for every single user accessing the content.
With an IPTV setup, you have a second 'connection' just for TV. The headend receives the feed once, and then can split the packet to all desinations on the internal network that want that channel.
Essentially reducing the required bandwidth.
(Instead of a connection from user -> internet/video source, multiplied by 1000.
You can have connection from 1000 users -> localized hub, and then a single connection from that hub to the video source)
So on the aggregate links, you've reduced your entire TV watching base to one connection, when there might have been thousands.
This doesn't help local node saturation, as you still have a connection to each user, but it certainly is more efficient for the big 'pipes'.
