The topic of the article is the architecture of MINOS corporate multimodal information and navigation system, and description of the system components and functioning of a corporate television subsystem. The applied Digital Signage (DS) technology is widely used for transmission of the advertising content and marketing, as well as in education, corporate communications, and multiuser negotiation systems. The survey presents several examples of DS technologies in information systems for various purposes. The developed infrastructure for operation of the system, including 4 stationary monitors, 4 nettops, network equipment, a web server, and a database server, is also presented. The client and the server software for managing of the corporate TV system software ensure administration and support for the relevant content through the web interface. Scenarios of using the system for different categories of users, as well as the principles of content management, which is displayed on the screen, based on special signals and events generated by time stamp or by the results of the user interaction, are considered. The primary function of the server is a dynamic formation of the schedules for the media files displayed on the screens. A schedule is an ordered list (queue). New media files are added to the end of the queue, while the media played from its beginning on the screens are excluded from the queue. The corporate TV system broadcasts information to the stationary screens (client systems) in accordance with the schedule, which is updated by the server dynamically based on a number of active events. In the corporate television system, each screen is characterized by an identifier, a description, an access key, a mode of operation and has its own schedule. The screens can be combined into groups and control all the screens in the same group as a single screen. Scenarios of using the system for different categories of users, as well as the principles of content management, which is displayed on screen, based on special signals and the events generated by time stamp or by the results of the user interaction, are considered. The further area for development is interactivity and personalization of the corporate television system by integrating it with the system of the biometric and RFID identification of the users. For each employee, who is automatically recognized, the corporate TV system will provide the output of the personalized information. It is expected to implement the management of the information output by means of gestures and speech. Another direction for development of the system is a navigation service, which allows a visitor to determine his (hers) location in the organization by scanning labels with QR-codes. A web application allows the visitor to orientate himself (herself) in the organization, using a laptop computer, and get the necessary background information.
