I have a hisense smart tv with vidaa OS that has a very limited app store and no possibility to install apps trough USB (afaik). For iptv I was limited to the ss iptv found in the store. So I found some link with instructions and in 10 seconds I was able to install both apps in my hisense TV.

The fact that smart iptv never past the beta version for this os, make it free. So enjoy like I will.

For the interested (the page is in Russian, so just follow the steps):

1- Open smart tv web browser and put the address http://hisense.alexxnb.ru

2- you will see a small list of apps. In front of each ou have a green button. Click there and it will turn red.

3- Exit with the back button and close browser. The apps should now appear near your installed apps.

4- Enjoy.
