Abstract: Multiple output streams of video and/or audio data are simultaneously generated from a large scale memory buffer array and sent to one or more customer devices for playback. The data is sent over networks, which use one or more protocols for data communication. Thus, for each network, a transport protocol stack is generated. The transport protocol stack is generated in hardware, thus greatly improving the throughput, and increasing the number of streams that can be generated. A wide data bus and wide address bus can be utilized because the protocol stack is generated in hardware, so that higher throughput can be achieved from the large scale memory buffer array. A plurality of protocol stack generators can have access to the same block of memory, allowing many output streams to be generated from a single copy of content in the large scale memory buffer array.
