Abstract
Compressed moving image data has heretofore taken the form of a “multiplex” in which header, image, and audio data are intermixed. Whether conveyed in files or sent in “streams”, such a multiplex does not naturally support multiple layers nor random access. A file/folder structure can alternatively be utilized wherein layers are contained in folders, and data for each frame for that layer are in files within each such folder. Using SATA or USB Flash memory there is no seek time penalty, unlike rotating disks. Computer networks and local memory access will naturally only access data needed for the layers currently being decoded. Thus, media and network bandwidth automatically matches the compressed data rates at those layers. Compressed layer files can further have index list headers so that regions of interest can be selectively accessed within moving frames using file pointer movement. The resulting file/folder compressed structure becomes an enabler for high quality random access of layered moving images, with layers all the way up to bit-exact lossless reproduction of the original image. Such high quality layered lossy and bit-exact lossless reproduction can be applied to integer pixels as well as to half-float IIF ACES pixels. The resulting coded representation is therefore suitable for movie masters, video masters, surveillance, networked remote video access, post-production servers, and many other moving-image applications that can benefit from layering and random access.
