Digital signage player with online update capabilities

I require a digital media player that can play multiple formats. This is to include pictures and video. I also require an online scheduler that controls the playscript and playtime. Will need to have mulitple screen layouts and a frame fir tv integration within the one of the screen layouts. Live update would also be required for safety and emergency purposes. I would like connectivity via 3g and LAN . I am happy to view software that has already been designed. Please only submit interest if prepared to have payment once completed . Please via [login to view URL] for type of player I am chasing. Thanks in advance.
