Abstract: Video data compression performance is improved through the use of multiple processors operating in parallel. The parallel processors perform motion or spatial estimation, where portions of a video frame are found to be similar to portions in reference frames. Because this estimation operation can be very time consuming, the use of multiple processors can reduce the overall time required, or they can enable higher-performing algorithms that might otherwise require a prohibitively long processing time. The motion or spatial estimation results are applied to reconstructed versions of the video frame data to enable high levels of video data compression.

Abstract: A method for delivering a data stream to a plurality of clients in a network. The method involves receiving the data stream from a media server, where the data stream includes a plurality of data packets and a data stream identifier associated with at least one of the plurality of data packets, securing the data stream received from the media server by applying a filter to the data stream to obtain a filtered data packet from the plurality of data packets based on the data stream identifier, encrypting the filtered data packet using an encryption scheme to obtain a encrypted media content, and distributing the encrypted media content to at least one of the plurality of clients in the network.

Abstract: Media files, including video, are compressed using information about subsequent processing, or transcoding, that will later be applied to the files. The compression allows the files to be uploaded over a limited-bandwidth device more quickly or less expensively than would otherwise be required. The files are decompressed prior to the transcoding process.
