<p>The inventive telecommunications interface is capable of collecting multiple asynchronous video, audio, graphic and data signals from a variety of different kinds of sources and retransmitting such signals in a suitable form for display or detection with one or more types of receiver equipment at one or more locations. The interface operates at rates ranging from several hundred bits per second to several gigabits per second. The telecommunications interface includes a dual port RAM (150) whose input and output operate asynchronously. Signals from the user sources are stripped of timing and source identification information and are written into the dual port RAM, while output processors (500-1, ....., 500-N) read previously stored user signals out from the dual port RAM. The output processors appropriately format the retrieved signals, which are then transmitted to the receiver equipment.</p> |
