Digital Signage CMS

I am interesting about a Digital Signage CMS which will allow us to prepare templates which will be played to remote Android players. I describe below the basic features we need: 1. I need each template to include windows (zones), where each window to be able to show different kind of content (e.g. video, streaming video, webtv, camera, photos, ticker (scrolling text), flash, webpage, widgets, ppt, pdf, gif, app, etc.). [login to view URL]: It should be able to play 2 videos simultaneously (eg. video in video) [login to view URL] text (ticker): it will be personal message or RSS. We will be able to setup color, dimensions, font, speed, direction, etc. [login to view URL]: in case of a touch screen, the window with the webpage will let the user to navigate to the webpage by touching the display [login to view URL]: we want several kind like weather, analogue clock, etc. [login to view URL]: we will be able to include an app which will run by touching the display [login to view URL]: in case the player has an HDMI in, we need to be able to connect external camera which will show content to a window 2. We will be able to make as many templates we need (different design) and each player will be able to load all of them and play them sequentially 3. It should support cloning in order to be able to create a display with the wanted content and then clone it 4. It should support creating groups of screens with the same content 5. As I explained above, it should support interactivity by touch, meaning that a user to be able to choose to touch an app, to touch a webpage, etc. (in case of a touch screen) 6. It also should support interactivity by keyboard, meaning that a user to be able to choose what to see by pressing a number to a USB standard arithmetic keyboard (in case of non touch screen) 7. It should support updating content without pausing playing the campaigns.
