IPTV is Internet Protocol T V. It refers to streaming shows over the internet. Grab a computer and visit hulu dot com as one example. If you have a Netflix account, you can stream that at no extra charge. IPTV in my humble opinion will compete with satellite very soon. I already watch shows that I want even though I don't sub to the channel those shows are on. Hope this helps. Have a great day!
NOTE: Many televisions today have connections to hook up a computer to them. I have my laptop hooked up to my set and with my internet speed, get the same if not better quality as I do on the satellite. If I take the 15 minutes to download the show instead of streaming it, I get HD quality video and the option of burninmg it to DVD if I like.
I have not even tried. I do my downloads at ninjavideo because I can get better quality there and the shows are there 24 hours after they are on tv. Each night they have the previous nights viewing on. Have a great day!
