ABSTRACT:
A broadcast and presentation system for synthesis of diverse data transmission signals and multimedia application subsystems. The system includes a signal processing line for transmitting information signals in multiple formats, a plurality of application subsystems for receiving input information in a predetermined signal format, a switching matrix for receiving input signals from the signal processing line and outputting the signals to the application subsystems that are described in destination and identification information that is embedded in the signal. The system further includes converters if necessary for receiving signals in one format and outputting the signals in another format according to the identification information that is embedded in the signal. The switching matrix may be programmable and controlled by a processor. A method of transmitting information signals includes embedding an information signal with destination and identification information; routing the information signal to a selected destination in accordance with the embedded destination information; and directing the signal to an application subsystem for processing the information signal at the selected destination in accordance with the embedded signal identification information. A method of receiving information signals includes receiving an information signal that has identification information embedded in the signal and routing the information signal to a selected application subsystem that is specified in the embedded identification information.
