摘要： A processing system [100] selectively renders pixels or blocks of pixels of an image and leaves some pixels or blocks of pixels unrendered to conserve resources. The processing system generates a motion vector field [125] to identify regions of an image having moving areas. The processing system uses a rendering processor [130] to identify as regions of interest those units having little to no motion, based on the motion vector field, and a large amount of edge activity, and to minimize the probability of unrendered pixels, or "holes", in these regions. To avoid noticeable patterns, the rendering processor applies a probability map [527] to determine the possible locations of holes, assigning to each unit a probability indicating the percentage of pixels within the unit that will be holes, and assigning a lower probability to units identified as regions of interest.

摘要： Systems, apparatuses, and methods for adaptive use-case based filtering of compressed video streams are disclosed. In one embodiment, a system includes at least a display and a processor coupled to at least one memory device. The system is configured to receive a compressed video stream. For each received frame of the compressed video stream, the system decompresses the compressed video frame into an unfiltered frame. Then, the system can utilize a first filter to filter the unfiltered frame to generate a filtered frame. In one embodiment, the first filter is a deblocking filter (DBF) combined with a sample adaptive offset (SAO) filter. Also, in this embodiment, the first filter is compliant with a video compression standard. The unfiltered frame and the filtered frame are provided as inputs to a second filter which performs a use -case specific de-noising of the inputs to generate a de-noised frame with reduced artifacts.

摘要： Systems, apparatuses, and methods for generating a model for determining a quantization strength to use when encoding video frames are disclosed. A pre-encoder performs multiple encoding passes using different quantization strengths on a portion or the entirety of one or more pre-processed video frames. The pre-encoder captures the bit-size of the encoded output for each of the multiple encoding passes. Then, based on the multiple encoding passes, the pre-encoder generates a model for mapping bit-size to quantization strength for encoding video frames or portion(s) thereof. When the encoder begins the final encoding pass for one or more given video frames or any portion(s) thereof, the encoder uses the model to map a preferred bit-size to a given quantization strength. The encoder uses the given quantization strength when encoding the given video frame(s) or frame portion(s) to meet a specified bit-rate for the encoded bitstream.

摘要： Systems, apparatuses, and methods for performing asynchronous memory clock changes on multiple displays are disclosed. From time to time, a memory clock frequency change is desired for a memory subsystem storing frame buffer(s) used to drive pixels to multiple displays. For example, when the real-time memory bandwidth demand differs from the memory bandwidth available with the existing memory clock frequency, a control unit tracks the vertical blanking interval (VBI) timing of a first display. Also, the control unit causes a second display to enter into panel self-refresh (PSR) mode. Once the PSR mode of the second display overlaps with a VBI of the first display, a memory clock frequency change, including memory training, is initiated. After the memory clock frequency change, the displays are driven by the frame buffer(s) in the memory subsystem at an updated frequency.

摘要： A feedback processing module [200] includes a memory [220] configured to store feedback [205] received from an encoder [125]. The feedback includes parameters associated with encoded graphics content generated by a graphics engine [105]. The feedback processing module also includes a processor [215] configured to generate configuration information for the graphics engine based on the feedback. The graphics engine is configured to execute a workload based on the configuration information. In some cases, the feedback processing module is also configured to receive feedback from a decoder that is used to decode the graphics content that is encoded by the encoder and generate the configuration information based on the feedback received from the decoder.

摘要： A video server (130, 305, 405, 505, 605) generates metadata (530, 535) representative of interpolation parameters (240-244) for portions of a first frame (200) representative of a scene (110) in a stream of frames (315, 335, 415) including the first frame. The interpolation parameters are used to generate at least one interpolated frame (205) representative of the scene subsequent to the first frame and prior to a second frame in the stream of frames. The video server incorporates the metadata into the stream and transmits the stream including the multiplexed metadata. A video client (135, 310, 410, 510, 610) receives the first frame representative the stream of frames including the metadata. The video client generates one or more interpolated frames (205) representative of the scene subsequent to the first frame and prior to a second frame in the stream of frames based on the first frame and the metadata. The video client displays the first frame, the one or more interpolated frames, and the second frame.

摘要： A display system [100] modifies display cycles of one or more displays [100] to perform a system operation [304] while avoiding visual perturbations at the one or more displays. The display system modifies, synchronizes, or both, blanking periods [204, 206] of the one or more displays such that the blanking periods equal or exceed a blackout duration [620] and overlap for at least the blackout duration. Then the system performs the system operation during an overlapping portion of the one or more blanking periods, where the system operation reduces availability of display data at the one or more displays.

摘要： Systems, apparatuses, and methods for implementing spatial block-level pixel activity extraction optimization leveraging motion vectors are disclosed. Control logic coupled to an encoder generates block-level pixel activity metrics for a new frame based on the previously calculated block-level pixel activity data from a reference frame. A cost is calculated for each block of a new frame with respect to a corresponding block of the reference frame. If the cost is less than a first threshold, then the control logic generates an estimate of a pixel activity metric for the block which is equal to a previously calculated pixel activity metric for a corresponding block of the reference frame. If the cost is greater than the first threshold but less than a second threshold, an estimate of the pixel activity metric is generated by extrapolating from the previously calculated pixel activity metric.

摘要： Systems, apparatuses, and methods for rendering images directly to a video encoder are disclosed. A game engine includes an embedded rendering unit configured to render images in different color spaces depending on the mode. The rendering unit renders images for a first color space only to be driven directly to a display while operating in a first mode. The rendering unit renders images for a second color space only which are provided directly to a video encoder while operating in a second mode. In a third mode, the rendering unit renders images for both color spaces. In one embodiment, the first color space is RGB and the second color space is YUV. The game engine also generates a plurality of attributes associated with each rendered image and the video encoder encodes each rendered image into an encoded bitstream based on the attributes associated with the rendered image.
