Abstract: Systems and methods are described for processing data from a sequential series of groups of frames to achieve a target average processing bit rate for a particular group of frames in the series. In an example, a look-ahead buffer circuit can be populated with a number of frames from a particular group of frames, and a bit allocation can be determined for a frame in the look-ahead buffer circuit using bit request information about all of the frames in the buffer. The look-ahead buffer circuit can be populated with streaming frame information in a first-in-first-out manner, and bit allocation processing can be performed for each frame, in a particular group of frames, based on a frame position in the look-ahead buffer circuit and further based on bit requests associated with other frames in the look-ahead buffer circuit.

Abstract: A motion vector candidate list is generated that can be used to encode or decode a motion vector used to predict the current block. A motion mode and motion information for a source block is determined. A motion vector used to predict the source block is added to the list responsive to determining that the motion mode for the source block is a translational motion mode and that a reference frame for the source block matches the reference frame for the current block. A warped reference motion vector is instead added to the list responsive to determining that the motion mode for the source block is a warped motion mode and that the reference frame for the source block matches the reference frame for the current block. A reference motion vector from the list is selected for encoding or decoding the current block motion vector.

Abstract: A method of partitioning in video coding for JVET, comprising representing a JVET coding tree unit as a root node in a quadtree plus binary tree (QTBT) structure that can have quadtree, ternary, or binary partitioning of the root node and quadtree, ternary, or binary trees branching from each of the leaf nodes. The partitioning at any depth can use asymmetric binary partitioning to split a child node represented by a leaf node into two or three child nodes of unequal size, representing the child nodes as leaf nodes in a binary tree branching from the parent leaf node and coding the child nodes represented by final leaf nodes of the binary tree with JVET, wherein further partitioning of child nodes split from leaf nodes via asymmetric binary partitioning may be restricted depending on the partitioning type of the parent node.

Abstract: Example implementations may relate to use of a light-control feature to control extent of light encountered by an image capture device of a self-driving vehicle. In particular, a computing system of the vehicle may make a determination that quality of image data generated by an image capture device is or is expected to be lower than a threshold quality due to external light encountered or expected to be encountered by the image capture device. In response to the determination, the computing system may make an adjustment to the light-control feature to control the extent of external light encountered or expected to be encountered by the image capture device. This adjustment may ultimately help improve quality of image data generated by the image capture device. As such, the computing system may operate the vehicle based at least on image data generated by the image capture device.

Abstract: Reduction in power consumption is not considered in the prior art documents. Provided is an encoding method for encoding image information and having: a step in which image information is input; an analysis step in which the characteristics of the input image information are analyzed; a bit depth output step in which the bit depth for video encoding is determined and output; and an encoding step in which the bit depth output in the bit depth output step is used and the input image information is encoded. The encoding method is characterized by the output bit depth being switched in the bit depth output step, on the basis of the analysis results from the analysis step.

Abstract: Techniques described herein are directed to the inline switching of video and/or audio codecs for video and/or audio data. A first device encodes data that includes portion(s) that are encoded using a first codec and portion(s) that are encoded using a second codec. The encoder may further encode supplemental information in the data. The supplemental information is used by the decoder to determine a transition between the first and second portion(s). The decoder can thus anticipate the transition and properly switch the codec used to decode the data in real-time. Techniques described herein are also directed to the splicing of locally-stored content into content received from a remotely-located source. For example, targeted advertisements that are stored locally may be played back during commercial breaks of live content. The locally-stored targeted advertisements may replace the commercials provided via the remotely-located source.

In one preferred embodiment, slice level offsets are added making the method particularly well-suited for slice level parallel processing. The extension of Chroma QP enhances functionality, flexibility and friendliness of the High Efficiency Video Coding (HEVC) standard for various applications.

Abstract: Multiple directional filters are applied against lines of pixels associated with a video block to determine filtered noise values. Each directional filter uses a different direction for filtering lines of pixels. For example, for each pixel value of the video block along a line of pixels having a direction corresponding to a directional filter, a difference can be determined between the pixel value and a corresponding pixel value along the line of pixels and outside of the video block. A value for line of pixels is determined as the sum of the absolute values of each of the differences, and a filtered noise value is determined as the sum of the values for the lines of pixels. The directional filter used to determine a lowest one of the filtered noise values for the video block is then selected. The video block is filtered using the selected directional filter.
