Re: Watching Asian cup 2015 online..
There are plenty of IPTV subscriptions available at a cost and most are in HD.
I subscribe to a service with 60+ sports channels from all the big networks (in The US, Canada, The UK - SKY, Nordics, Ireland etc) so do a google search and be enlightened. I had to by a MAG250 box at a premium, but worth it in the end... (I don't watch sports at all but they are included in the 200+ channel lineup)
If you are looking for any free services, I would not count on you finding anyone and if you do, the quality may be thereafter...
