20090256730 | Advanced Lossless Bit Coding - A bit coding method modifies the bit-steam information in such a way as to provide a very high compression during lossless symbol coding and may be used as a preprocessor for Huffman and arithmetic encodings or on its own. A bit rearrangement scheme (BRS) improves the run length within a data symbol set and achieves a more efficient data-to-symbol mapping. The BRS is implemented on the data symbol set in a column-by-column fashion. The BRS can be combined with any available lossless coding scheme, providing for a more efficient lossless bit coding scheme (ALBCS). | 10-15-2009 |
20090162032 | Smart Viewing Rights System and Switch - A method and apparatus that enables the transfer of viewing rights on an individual basis that allows the individual to view high-definition content from any source when the rights are available. If the viewing rights of the high-definition version are not available to a viewer the same content may be viewed at lower definition. Hence the invention enables moving of the viewing rights with an individual rather than a content viewing terminal. It also allows the content to be reviewed in very low preview resolution but prevents the use in higher resolutions till rights are secured. The benefit is securing and guarding the rights for high-definition reproduction but allowing low quality viewing by using the same compressed content. The HDMI-in to HDMI-out format used in the implementation makes viewing of content from all sources possible, whether directly streamed or from a pre-stored location. | 06-25-2009 |
20090080665 | Method of Generating Secure Codes for a Randomized Scrambling Scheme for the Protection of Unprotected Transient Information - In many instances it is necessary to store and transfer information and data on a temporary basis. Typically this information and data is transient but is vulnerable to capture and piracy as it is not in an encrypted state. Therefore a unique method is disclosed that performs randomized scrambling of unprotected digital information that make it unreadable, or otherwise unusable, without the appropriate descrambling. In order to be effective and secure the method requires a large population of scrambling patterns, or codes, and assigns them index numbers. Scrambling patterns are randomly chosen for use in the scrambling of the information and data. Unique schemes for developing this large population of patterns and choosing at random the usable set at each interval or usage. In particular the method is useful in the protection of digital content. | 03-26-2009 |
