IPTV management, overlay digital signage in live channels, web interface, mag250 box or android/linux based

2. a system who can manage tv box (android or linux based) by a web interface. The content shown on each TV plugged with the box is selectable and manageable via a web control interface through any number of authorised administrators (the “TV Managers”) – who control all screens in real time whether they are located in an individual betting shop, an HQ office or their home /internet cafe. the content can be: live iptv channels, videos, picture show, other. And if is possible to put text and logo overlay the screen (digital signage). would be nice also the possibility to add a .m3u file from the users wich contain all the live channels and to be organized, so that he can choose as content to show and do digital signage.
