| 20110261737 | TRANSMIT AND RECEIVE METHOD FOR A DATA SERVICE - A method includes receiving, at a transmit site, a first stream of packets addressed to an end user device in a first address space. The first stream of packets is encapsulated to form a second stream of packets addressed in a second address space. A first packet of the second stream of packets is assigned to a first radio frequency channel of a plurality of radio frequency channels. A second packet of the second stream of packets is assigned to a second radio frequency channel of the plurality of radio frequency channels. The first packet is transmitted via the first radio frequency channel and, in parallel, the second packet is transmitted via the second radio frequency channel. | 10-27-2011 |
| 20090041128 | SYSTEM AND METHOD FOR USING PATTERN VECTORS FOR VIDEO AND IMAGE CODING AND DECODING - An exemplary embodiment of the invention relates to a method of using pattern vectors for image coding and decoding. The method comprises converting a block of image data into a set of transform coefficients, quantizing the transform coefficients such that a number of the coefficients become zero, constructing a single entity or bit vector indicating which coefficients are non-zero, coding the single entity or bit vector as an integer using an adaptive, semi-adaptive or non-adaptive arithmetic coder, coding the values of the coefficients in any fixed order, using an adaptive, semi-adaptive or non-adaptive arithmetic coder, or some other coder, and coding all coefficients except the zero coefficients. The system and method of decoding data relate to the corresponding hardware and process steps performed by the decoder when decoding a bitstream coded as described herein. | 02-12-2009 |
