Abstract: A system and method for the distribution of digital media content makes use of a network control element to manage the fragmentation of the digital content and to distribute the fragments of the digital content to different endpoint elements in the network. The network control element responds to endpoint element requests for the digital media content by allowing the various endpoint elements to store the fragments of the digital media content and to transfer the fragments to the requesting endpoint element under the control of the network management element. This spreads the network traffic across the network and prevents the development of a single bottleneck in the distribution network.

Abstract: A single instruction, multiple data (SIMD) architecture for controlling the processing of plurality of data streams in a digital subscriber line (DSL) system has a memory for storing the data from the channels, a processor operatively coupled with the memory for processing data from the data streams, and a controller for controlling the processor. Storing the data in the memory de-couples the operating rate of the processor and the operating rate of the data streams.

Abstract: An asymmetric digital subscriber line (ADSL) termination unit, which at the transmission end includes a descrambler and a compressor between its scrambler and interleaver. The present invention provides for the use of compression on the data in a channel to remove some of the inherent redundancy, in order to yield much better throughput, particularly in conjunction with certain powerful forward error correction (FEC) schemes. In this manner the compression may be performed on unscrambled data that has a higher redundancy than scrambled data, thereby improving compression. At the reception end, the ADSL termination unit includes a decompressor and a scrambler between its deinterleaver and descrambler.
