SopCast is a pretty classic app with which you can play live TV posts from each country (analog and digital, free and paid, too) using only the Internet connection and all you must to do is to install it in a few seconds and then to...
watch TV, 'cause you're READY!
The image is very clear, the sound is stereo and the best function is that you can create your own... TV post and transmit it for free with SopCast!
This is a free app and you can download it only from SopCast.com or .org. Be careful not to pay for SopCast or if you already did this, request a full refund, because, as I already said, SopCast is completely free!
I've downloaded SopCast when my TV was broken and I clearly remember that I was very satisfied with it! You almost don't need a TV at all, if you have SopCast!
P.S. You also can download it for MacOS, Android and iOS.
