  • Publication number: 20200177893
    Abstract: Techniques and tools are described for decoding jointly coded information. For example, a decoder decodes a variable length code [“VLC”] signaled at macroblock level that jointly represents a transform type signal level, transform type, and subblock pattern. The decoder decodes one or more VLCs signaled at block level, each jointly representing a transform type and subblock pattern. The decoder may select between multiple VLC tables for the VLCs signaled macroblock level and/or block level.

  • Publication number: 20200177887
    Abstract: Approaches to selection of motion vector (“MV”) precision during video encoding are presented. These approaches can facilitate compression that is effective in terms of rate-distortion performance and/or computational efficiency. For example, a video encoder determines an MV precision for a unit of video from among multiple MV precisions, which include one or more fractional-sample MV precisions and integer-sample MV precision. The video encoder can identify a set of MV values having a fractional-sample MV precision, then select the MV precision for the unit based at least in part on prevalence of MV values (within the set) having a fractional part of zero. Or, the video encoder can perform rate-distortion analysis, where the rate-distortion analysis is biased towards the integer-sample MV precision. Or, the video encoder can collect information about the video and select the MV precision for the unit based at least in part on the collected information.

  • Publication number: 20200177890
    Abstract: Described tools and techniques relate to signaling for DC coefficients at small quantization step sizes. The techniques and tools can be used in combination or independently. For example, a tool such as a video encoder or decoder processes a VLC that indicates a DC differential for a DC coefficient, a FLC that indicates a value refinement for the DC differential, and a third code that indicates the sign for the DC differential. Even with the small quantization step sizes, the tool uses a VLC table with DC differentials for DC coefficients above the small quantization step sizes. The FLCs for DC differentials have lengths that vary depending on quantization step size.

  • Patent number: 10672880
    Abstract: A conductive layer for a thin film transistor (TFT) array panel includes a multi-layered portion defining a source electrode and a drain electrode of a TFT device, and includes a first sub-layer, a second sub-layer, a third sub-layer, and at least one additional sub-layer. The third and the first sub-layers include indium and zinc oxide materials. An indium to zinc content ratio in the first sub-layer is greater than that in the third sub-layer. An indium to zinc content ratio in the additional sub-layer is formulated between that in the first and the third sub-layers. The content ratio differentiation between the first and the third sub-layers affects a lateral etch profile associated with a gap generated in the second conductive layer between the source and the drain electrodes, where the associated gap width in the third sub-layer is wider than that in the first sub-layer.

  • Patent number: 10674159
    Abstract: Various embodiments of the present technology generally relate to encoding techniques. More specifically, some embodiments relate to encoding techniques for screen data. Intra block copy (IntraBC) using motion compensation within a frame (not between frames) is very useful for encoding data captured from screen. Unfortunately, this tool is not included in most of video coding standards, including the base version of HEVC (i.e., H.265). Various embodiments of the present technology utilize encoding techniques to simulate IntraBC with compliant syntax. For example, embodiments divide a high-resolution frame into smaller areas and then encode these areas independently as if these smaller areas were independent frames.

  • Publication number: 20200169749
    Abstract: Techniques and tools for video coding/decoding with motion resolution switching and sub-block transform coding/decoding are described. For example, a video encoder adaptively switches the resolution of motion estimation and compensation between quarter-pixel and half-pixel resolutions; a corresponding video decoder adaptively switches the resolution of motion compensation between quarter-pixel and half-pixel resolutions. For sub-block transform sizes, for example, a video encoder adaptively switches between 8×8, 8×4, and 4×8 DCTs when encoding 8×8 prediction residual blocks; a corresponding video decoder switches between 8×8, 8×4, and 4×8 inverse DCTs during decoding.
