Abstract
A video port aggregator receives plural asynchronous video data streams. Corresponding input buffers generate video data and a status signal. A memory controller writes the video data in corresponding locations within an external memory. A channel triggers the memory controller to read data out of the external memory for transmission to a single video output port when said corresponding status signal indicates receipt of a predetermined portion of data. This read out of the external memory being faster than the writing. The channel sequencer triggers the memory controller to read data out of the external memory video data of a highest priority asynchronous video data stream having a received next portion of data.
