A distribution system that can push computer-generated information to a mobile/peripatetic device 6 interspersed with a stream of live video and audio communications. The system provides distribution means 4 for use with mobile telecommunications networks 5 wherein the user perceives the video streaming process to be in real time, and a mechanism switches the display to graphics/text when it is necessary to buffer the incoming video stream or when congestion or delays arise due to a network event. The system includes a plurality of transcoders 2 for the conversion of data/graphics from external information sources 17 into a display format suitable for display on a mobile receiving device and pushes the information from a central workstation to the mobile receiving device. The video and audio data are provided by a live video/audio stream source 3. The system includes a distribution switch 4 enabling control of the display on the mobile receiving device through a message protocol.
