The hardware requirements include:
Content Controller
The content controller is driven by RISC computers and the operating system is Linux based. This content controller enables users to control any number of screens, from 1 to 5,000 if needed. The controller is able to support all digital media inputs – AVI, MPEG, QTIME, DIVX, BMP, JPG, TIF, GIF, wav, mp3 and CD Audio. The content controller is also capable of retrieving real-time information from Web-based news sources available on the Internet.
STB
The STB (Set Top Box) is the device that drives the content on the screens. Content is stored at each location. Each STB is capable of driving one or more screens at each site.
STBs carry the information which includes advertisements, news, sports, corporate messages, emergency procedures, promotions etc and store it at each screen site on the network. The STB is the client’s end user device on the network. These provide a comprehensive suite of software for installation on approved devices. The number of STBs required for a particular network depends upon the kind of information displayed. If the content is the same across the entire network of screens then only one STB is required; if the information varies from screen to screen then a separate STB is required for individual screens.
