ABSTRACT:
A multimedia switching apparatus switches multimedia signals including audio and video signals received from a public telecommunications network to distribute the multimedia signals automatically. The gateway receives the multimedia signals and generates a separate audio and video signal output. The audio signal is switched by an audio switch to a destination under the control of an automatic call distribution arrangement to automatically control the switching of the audio signal. A separate video switch is provided for switching the video signal to a destination logically associated with the destination of the audio signal. The video switch is controlled by monitoring the events in the audio switch to control the switching of the video signal so that it is switched to the logically associated destination. The switching operations of the audio switch are copied by the video switch.
