Digital Signage Software

Hi team, Need to develop a software base on cms style (or the freelancer can propose other format) that I can play multimedia format on the screens, divide in zones where we're able to stream rss feed, radio and video input such as dvd player or camera. The storage can be on icloud or other storage format. The application must run automatically on specific time, offer live interaction by rss feed for audio, text and video, web access, security to attacks (like blogs offer), live preview of each monitor that the device is installed. Ex. Standard digital signage applications. Please, if you have any need to ask questions, please, do. Thanks, On-line Crew.
