| Number | Title | Issue Date |
| 8099285 | Temporally accurate watermarking system and method of operation A system for identifying audio data is provided. The system includes a transform system receiving left channel audio data and right channel audio data and generating a plurality of frequency bins of left channel magnitude data, left channel phase data, right channel... | 01/17/2012 |
| 7724964 | Digital 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... | 05/25/2010 |
| 7548853 | Scalable 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... | 06/16/2009 |
| 7392195 | Lossless 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... | 06/24/2008 |
| 7333929 | Modular scalable compressed audio data stream Methods and apparatus are provided for the creation and utilization of unique compressed data stream compositions, structures and formats which allow for the alteration of the data stream's data rate without first decoding the data stream back to its uncompressed fo... | 02/19/2008 |
| 6741323 | Motion picture subtitle system and method In a motion picture subtitle system a shutter such as a mechanical dowser, LCLV, or E/O diffuser is inserted in the optical path between the supplemental projector and the motion picture screen and synchronized to the projection of the subtitles to reduce visual art... | 05/25/2004 |
| 5408184 | Constant-temperature jacket for syringe-type electrolyte conductivity test cells An apparatus for measuring the conductivity of an electrolyte comprises at least one conductivity cell, e.g., syringe-type conductivity cell and a constant temperature jacket. The syringe-type conductivity cell preferably employed in the apparatus compris... | 04/18/1995 |
