  • Publication number: 20200287528
    Abstract: A circuit includes a first power node configured to carry a first voltage having a first voltage level, a second power node configured to carry a second voltage having a second voltage level, an output node, and first and second cascode transistors coupled between the first power node and the output node and to each other at a node. A bias circuit uses the first and second cascode transistors to generate an output signal at the output node that transitions between the first voltage level and a third voltage level, and a delay circuit generates a transition in a first signal from one of the first or second voltage levels to the other of the first or second voltage levels, the transition having a time delay based on the output signal. A contending transistor couples the node to the second power node responsive to the first signal.

  • Publication number: 20200252627
    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.

  • Patent number: 10735747
    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.

  • Patent number: 10718332
    Abstract: A water lubrication air compression system disposes an lubricant heat dissipation system at a bearing chamber close to the high pressure end of the compressor for cooling and circulating lubricant due to the rise of temperature during operation of the compressor, hence enhancing the ability and stability of the compressor. On the other hand, a negative pressure system is connected to the air chambers between the oil lubrication and the water lubrication of the compressor in order to provide a negative pressure. If any leak of water vapor at the compressor chamber or oil vapor at the bearing chamber, the negative pressure system is able to produce a negative pressured condition toward the sealing structure so that the oil lubrication can be effectively isolated from the water lubrication and inter-contamination between the lubricant and water can be avoided.

  • Patent number: 10708594
    Abstract: Disclosed herein are exemplary embodiments of innovations in the area of encoding pictures or portions of pictures and determining whether and how certain encoding operations should be performed and flagged for performance by the decoder in the bitstream. In particular examples, various implementations for selectively encoding picture portions (e.g., blocks) in a skip mode (e.g., as in the skip mode of the H.265/HEVC standard) are disclosed. Embodiments of the disclosed techniques can be used to improve encoder efficiency, decrease overall encoder resource usage, and/or improve encoder speed. Such embodiments can be used in encoder modes in which efficient, fast encoder performance is desired (e.g., during encoding of live events, such as video conferencing).

  • Patent number: 10687075
    Abstract: Techniques and tools for sub-block transform coding are described. 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. The video encoder may determine the transform sizes as well as switching levels (e.g., frame, macroblock, or block) in a closed loop evaluation of the different transform sizes and switching levels. The encoder and decoder may use different scan patterns for different transform sizes when scanning values from two-dimensional blocks into one-dimensional arrays, or vice versa. The encoder and decoder may use sub-block pattern codes to indicate the presence or absence of information for the sub-blocks of particular blocks.
