摘要:
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.
