HOW MUCH BANDWIDTH DOES EACH TV CHANNEL CONSUME FROM THE NETWORK WHEN USING IPTV ON LOCAL IP NETWORK?
Question by d j:
How much Bandwidth does each Television channel consume from the network when using IPTV on local IP network?
thanks but i thought it needs more … like 6 or 7.2 MB … i am not sure
Again, Thanks DoH but my Question is about IPTV over the Local Network not over WAN or internet. i.e. without compression methods.

BT Vision allocate 1.5Mb/s for a single streaming on demand tv channel to guaruntee no breakup or degredation so I’d guess that would be a good guideline to go by.

IPTV doesn’t work the same as broadcast TV(includes satellite, cable and over the air). With broadcast TV every channel is sent to the TV and the tuner on the TV is used to display the one you want to watch.
With IPTV, only the station you want to watch is actually sent to the TV. IPTV uses IP Multicast, which uses a multicast join message back to the provider to tell them which channel you want to watch, then that channel is streamed to your TV.
The amount of bandwidth consumed is a function of the compression scheme used on the video and voice portions of the signal. I’m not sure what video uses, but VoIP consumes about 8Kbps using g.729 compression. VoIP doesn’t use multicast, it’s just standard unicast over UDP.
