NumberTitleIssue Date
7724964Digital intermediate (DI) processing and distribution with scalable compression in the post-production of motion pictures
Scalable image compression is exploited to facilitate the creative process in the post-production of motion pictures. Specifically, digital intermediate (DI) processing of motion pictures is enabled by dynamically rendering proxies 126 (steps 122, 124, 128) i...

7548853Scalable compressed audio bit stream and codec using a hierarchical filterbank and multichannel joint coding
A method for compressing audio input signals to form a master bit stream that can be scaled to form a scaled bit stream having an arbitrarily prescribed data rate. A hierarchical filterbank decomposes the input signal into a multi-resolution time/frequency represent...

7392195Lossless multi-channel audio codec
A lossless audio codec segments audio data within each frame to improve compression performance subject to a constraint that each segment must be fully decodable and less than a maximum size. For each frame, the codec selects the segment duration and coding paramete...
