摘要： A block transform-based digital media codec achieves faster performance by re-mapping components of the digital media data into vectors or parallel units on which many operations of the transforms can be performed on a parallel or single-instruction, multiple data (SIMD) basis. In the case of a one-dimensional lapped biorthogonal transform, the digital media data components are re-mapped into vectors on which butterfly stages of both overlap pre-/post-filter and block transform portions of the lapped transform can be performed on a SIMD basis. In the case of a two-dimensional lapped biorthogonal transform, the digital media data components are re-mapped into vectors on which a Hadamard operator of both overlap pre-/post-filter and block transform can be performed on a SIMD basis.

摘要： A distributed system for distributing conferencing data such as video, audio, and other conference data. The distributed system includes a conference data dispatch system, multiple conference participant computing systems, and a network distribution path through which conference data may be distributed from the conference data dispatch system to the various conference participant computing systems. The conference data is segmented. Each segment is encoded to be suitable to a particular class of participant computing systems. The encoded segments may be cached in an intermediary computing system to thereby avoid a strict unicast model for distributing conference data.
