IPTV vs DTH

I prefer DTH services purely because its not connected to the phone, and if something does happen to the phone line then the tv wont be affected! But however IPTV is popular just like DTH.

But which one theoretically is better out of the both, IPTV or DTH. I know they have their own advantages and disadvantages but what are they.

Maybe i should have written STB service rather than DTH, im not sure which one is right!!!!

Both have their own advantages and disadvantages, but overall I think DTH is much better because you wont face any connectivity issues. For example if your internet is down that ultimately means your TV is down, but then on the other hand if its raining really bad then your DTH service with have signal problems. With the IPTV service you will also have to make sure that your connection is stable and fast, otherwise the live programs will lag behind.
