Abstract: A television storage system for editing and special effects equipment in which live video input material is recorded and converted into two parallel streams of real time live video with the input video recorded as compressed segments independently accessible on multiple synchronous disk drives.

Abstract: A method and apparatus for transforming image data by recursively interleaving the data to generate blocks of component image coefficients having form suitable for subsequent quantization, motion estimation, and/or coding. In preferred embodiments, the transformed data are in optimal form for coding by conventional circuitry in accordance with the conventional JPEG or MPEG compression algorithm. In preferred embodiments, the invention includes two memory arrays (each having capacity to store one or more N.times.M image data blocks), and an analyzer connected between the memory arrays. The analyzer receives horizontal vectors (such as full rows) of an image data block stored in the first memory, transforms each horizontal vector into two vectors (each comprising half as many words as the horizontal vector), interleaves the two vectors, and writes the resulting interleaved data (an orthogonal representation of the horizontal vector) into a row of the second memory.
