| 20090097561 | Bit depth enhancement for scalable video coding - A video system includes an analyzer and a bit depth predictor. The analyzer receives a first coded video signal, which is indicative of first values for pixels. The first values are associated with a first bit depth. The analyzer, for each pixel, analyzes the first values for the pixels located in a neighborhood that contains said each pixel. The bit depth predictor, based at least in part on the analysis, generates a second coded video signal that is indicative of second values for the pixels. The second values are associated with a second bit depth that is different than the first bit depth. | 04-16-2009 |
| 20090167775 | MOTION ESTIMATION COMPATIBLE WITH MULTIPLE STANDARDS - A motion estimation engine may be implemented to support multiple video encoding standards. The motion estimation engine may be designed to support two macroblock partitioning modes: one for frame type video signals and the other for mixed frame-field type video signals. Additionally, the motion estimation engine provides the mixing unidirectional option (forward/backward) and the mixing bidirectional option. Furthermore, the motion estimation engine may use a unified 4-tap interpolation filter for fractional macroblock search during motion estimation. | 07-02-2009 |
| 20090168871 | Video motion estimation - In accordance with some embodiments of the present invention, distortion may be calculated using hardware for purposes of motion estimation. The distortion may be determined in the frequency domain. In some embodiments, a modified Haar wavelet transform may be utilized. The penalty in terms of the number of motion vectors may be determined for each location to achieve better distortion in some embodiments. A look up table may be utilized to determine an acceptable penalty. In some cases, the user can input information about an acceptable penalty. | 07-02-2009 |
| 20090168881 | CONFIGURABLE MOTION ESTIMATION - In some embodiments, a motion estimation method and engine are provided. | 07-02-2009 |
| 20090168883 | CONFIGURABLE PERFORMANCE MOTION ESTIMATION FOR VIDEO ENCODING - A motion estimation engine may be implemented to include a skip checking module, an integer search module, a macroblock partitioning module, a fractional search module, a bidirectional motion estimation refinement module, and an intra search module. The motion estimation engine may perform fractional search/bidirectional motion estimation refinement and intra search in parallel. Additionally, modules in the motion estimation engine may be partially or fully turned on or off to accommodate different motion estimation requirements. Furthermore, the motion estimation engine may implement early exit strategy to further save computation. | 07-02-2009 |
| 20090172676 | Conditional batch buffer execution - A batch computer or batch processor may implement conditional execution at the command level of the batch processor or higher. Conditional execution may involve execution of one batch buffer depending on the results achieved upon execution by another batch buffer. | 07-02-2009 |
| 20090262798 | Tone mapping for bit-depth scalable video codec - A scalable video codec may convert lower bit depth video to higher bit depth video using decoded lower bit depth video for tone mapping and tone mapping derivation. The conversion can also use the filtered lower bit depth video for tone mapping and tone mapping derivation. | 10-22-2009 |
| 20090284526 | RENDERING MULTIPLE CLEAR RECTANGLES USING A PRE-RENDERED DEPTH BUFFER - According to some embodiments, systems, methods, apparatus, computer program code and means are provided to set a first depth value associated with a plurality of pixels of a video image comprising a plurality of planes, create a first clear rectangle with respect to the first depth value, color render the pixels that are not associated with the first clear rectangle, and render the plurality of planes. | 11-19-2009 |
| 20090323807 | Enabling selective use of fractional and bidirectional video motion estimation - A video encoder may analyze whether or not to do bidirectional or fractional motion estimation dependent on the cost in terms of bits needed to do the motion estimation versus the benefit of the analysis in terms of distortion, in some embodiments. | 12-31-2009 |
| 20090327662 | Managing active thread dependencies in graphics processing - A scoreboard for a video processor may keep track of only dispatched threads which have not yet completed execution. A first thread may itself snoop for execution of a second thread that must be executed before the first thread's execution. Thread execution may be freely reordered, subject only to the rule that a second thread, whose execution is dependent on execution of a first thread, can only be executed after the first thread. | 12-31-2009 |
| 20100008427 | Color gamut scalability techniques - Techniques are described that can be used to either compress or expand video. Color compression techniques are described that can be used to compress the wide color gamut content into lower color gamut for inclusion in a baseline layer. Color expansion techniques are described that convert lower color gamut data into wider color gamut format for inclusion in an enhancement layer. Both of the baseline video stream and enhancement layer video streams may be transmitted through a channel or stored in a memory device to be viewed later. Accordingly, both baseline and enhancement video layers are available so that either lower or higher quality displays can be used to display video. | 01-14-2010 |
| 20100031268 | Thread ordering techniques - Techniques are described that can be used to ensure ordered computation and/or retirement of threads in a multithreaded environment. Threads may contain bundled instances of work, each with unique ordering restrictions relative to other instances of work packaged in other threads in the system. When applied to 3D graphics, video and image processing domains allow unrestricted processing of threads until reaching their critical sections. Ordering may be required prior to executing critical sections and beyond. | 02-04-2010 |
| 20100146314 | Power aware software pipelining for hardware accelerators - Forming a plurality of pipeline orderings, each pipeline ordering comprising one of a sequential, a parallel, or a sequential and parallel combination of a plurality of stages of a pipeline, analyzing the plurality of pipeline orderings to determine a total power of each of the orderings, and selecting one of the plurality of pipeline orderings based on the determined total power of each of the plurality of pipeline orderings. | 06-10-2010 |
| 20110002390 | METHODS AND SYSTEMS FOR MOTION VECTOR DERIVATION AT A VIDEO DECODER - Method and apparatus for deriving a motion vector at a video decoder. A block-based motion vector may be produced at the video decoder by utilizing motion estimation among available pixels relative to blocks in one or more reference frames. The available pixels could be, for example, spatially neighboring blocks in the sequential scan coding order of a current frame, blocks in a previously decoded frame, or blocks in a downsampled frame in a lower pyramid when layered coding has been used. | 01-06-2011 |
