20120030714 | METHOD AND SYSTEM FOR REMOTE TELEVISION REPLAY CONTROL - A method, system, computer medium, and other embodiments for integrating unrelated web hosted services with stand-alone media-based devices are provided. Users can access and control the media-based device conveniently with a web-browser through various portals on the Internet. In one embodiment, users access the media-based device through one or more unrelated web portals, so as to control and to program the media-based device in a single web session, and to see information both stored on the media-based device and originating from third-party online sources of information and services in a single integrated presentation. | 02-02-2012 |
20090217141 | SETS OF RATE-COMPATIBLE UNIVERSAL TURBO CODES NEARLY OPTIMIZED OVER VARIOUS RATES AND INTERLEAVER SIZES - A method and apparatus for Turbo encoding uses a set of rate-compatible Turbo Codes optimized at high code rates and derived from a universal constituent code. The Turbo Codes have rate-compatible puncturing patterns. | 08-27-2009 |
20090044081 | METHOD AND SYSTEM FOR PROVIDING SHORT BLOCK LENGTH LOW DENSITY PARITY CHECK (LDPC) CODES IN SUPPORT OF BROADBAND SATELLITE APPLICATIONS - An approach is provided for encoding short frame length Low Density Parity Check (LDPC) codes. An encoder generates a LDPC code having an outer Bose Chaudhuri Hocquenghem (BCH) code. Structure is imposed on the LDPC codes by restricting portion part of the parity check matrix to be lower triangular and/or satisfying other requirements such that the communication between bit nodes and check nodes of the decoder is simplified. Further, a cyclic redundancy check (CRC) encoder is supplied to encode the input signal according to a CRC code. This approach has particular application in digital video broadcast services over satellite. | 02-12-2009 |
