| 20100061645 | SYSTEM AND METHOD FOR VIDEO ENCODING USING ADAPTIVE LOOP FILTER - Disclosed herein is a method for reducing blocking artifacts at the boundary between adjacent blocks reconstructed from a frame of compressed video information. The video information includes a prediction stage parameter with respect to at least one of the blocks. The method includes reconstructing the at least one block based on the prediction stage parameter, computing a residual error attribute from the reconstructed block, computing a filter strength value based on a baseline filter strength and at least one incremental value, wherein the incremental value is selected from a plurality of preset values based at least on one of the prediction stage parameter and residual error attribute associated with the at least one block and filtering the boundary adjacent to the at least one block using the selected filter strength value. | 03-11-2010 |
| 20100061461 | SYSTEM AND METHOD FOR VIDEO ENCODING USING CONSTRUCTED REFERENCE FRAME - Disclosed herein is a method for digital video encoding prediction comprising creating a constructed reference frame using an encoder and compressing a series of source video frames using the constructed reference frame to obtain a bitstream including a compressed digital video signal for a subsequent decoding process. The constructed reference frame is omitted from the series of digital video frames during the subsequent viewing process. | 03-11-2010 |
| 20100061455 | SYSTEM AND METHOD FOR DECODING USING PARALLEL PROCESSING - A method for decoding a stream of encoded video data is disclosed. The video stream includes partitions that have been compressed using lossless encoding. Each partition includes rows that have also been encoded using intra-frame or inter-frame encoding, for example. During the decoding process, two or more of the partitions are entropy decoded on two or more processors in parallel, except that partitions containing adjacent rows in the frame are decoded with an offset so that at least a portion of the output of the entropy decoding of one partition can be used as input in the entropy and intra/inter-frame decoding of the other. | 03-11-2010 |
| 20100061444 | SYSTEM AND METHOD FOR VIDEO ENCODING USING ADAPTIVE SEGMENTATION - A method for decoding compressed video information is disclosed. The video information can include a plurality of frames each having a plurality of blocks. The method includes reading from the video information a segment map that associates blocks in the frame with four segment identifiers. Each segment identifier is associated with one or more segment parameters, such as quantization parameters, loop filter type, loop filter strength and sub-pixel interpolation filter. The blocks in each segment are then decoded using the associated segment parameters. Segment parameters can persist to following frames unless overwritten by a subsequent frame. A frame can also include a bit suppressing segmentation, in which case default parameters are sued for all blocks in the frame. | 03-11-2010 |
| 20090303098 | System and Method for Data Communication - Disclosed herein is a method to enable a mobile device to function as a user interface to a remote application. The method includes actuating a user-actuated control on the mobile device to generate a device-output signal in accordance with a first protocol; transmitting the device-output signal over a licensed radio frequency spectrum to a wireless base station located on the same premises as the mobile device; establishing communication between the wireless base station and the remote application having a user interface that accepts a user-command signal in accordance with a second protocol that is incompatible with the circuitry and programming of the mobile device; generating a constructed-input signal based on the device-output signal; and transmitting the constructed-input signal to the remote application as the user-command signal in accordance with the second protocol to permit the mobile device to function as a controller for the remote application. | 12-10-2009 |
