I use an FTP connection to install android .apk, .exe or .air files to install that platform on every type of device and it works fully online with almost no limit. So I can publish, design and manage any content on TVs as digital signage platform. I can control them from a dashboard and can edit each of them individually with a different theme and content with any purpose. I can even make them such as touch screen so clients, guests or customers may control, see prices, fill forms etc.
This is how I can create a template and install the contents from my very own ftp such as videos, images etc. with the size and pixel I have given.
This is where I can find my each station with their status that I can stop, restart, off or on them back.
