International Classification:

G06F 15/18

US Classification:

706 12

Abstract:

In one embodiment, when executing data compression or decompression for a data set, a particular compression category of the data set is determined, and a corresponding probability table specific to the particular compression category of the data set is accessed. Then, one of either arithmetic coding (e. g. , an encoder device) or decoding (e. g. , a decoder device) may be performed on the data set based on the specific probability table. Specifically, in one or more other embodiments, techniques may statistically generate probability tables specific to particular compression categories.

US Classification:

257415, 438 50, 257E29324, 257E21002

Abstract:

A method and apparatus are disclosed for reducing stiction in MEMS devices. The method comprises patterning a CMOS wafer to expose Titanium-Nitride (TiN) surface for a MEMS stop and patterning the TiN to form a plurality of stop pads on the top metal aluminum surface of the CMOS wafer. The method is applied for a moveable MEMS structure bonded to a CMOS wafer. The TiN surface and/or plurality of stop pads minimize stiction between the MEMS structure and the CMOS wafer. Further, the TiN film on top of aluminum electrode suppresses the formation of aluminum hillocks which effects the MEMS structure movement.

Abstract:

Aspects of the disclosure provide a method, an apparatus, and non-transitory computer-readable storage medium for video decoding. The apparatus includes processing circuitry. The processing circuitry can decode, from a bitstream, pictures associated with views of respective layers in a coded video sequence (CVS). The processing circuitry is configured to determine, based on a first supplemental enhancement information (SEI) message and a second SEI message, positions of the views to be displayed in one dimension. The first SEI message includes scalability dimension information (SDI) and the second SEI message includes multiview view position (MVP) information. The processing circuitry is configured to display the decoded pictures based on the positions of the views in the one dimension.

Abstract:

Aspects of the disclosure provide a method, an apparatus, and non-transitory computer-readable storage medium for video decoding. The apparatus includes processing circuitry that is configured to decode a supplemental enhancement information (SEI) message that indicates independent region output information. The independent region output information indicates an independent region that is independently decodable in a current picture. The processing circuitry determines the independent region in the current picture based on offset information and dimension information of the independent region in the independent region output information. The processing circuitry decodes the determined independent region irrespective of whether the entire current picture is decoded. The processing circuitry outputs the decoded independent region based on a position indicated by the offset information and a size indicated by the dimension information of the independent region.

Abstract:

A method of video decoding performed in a video decoder is disclosed. A syntax element can be received from a bitstream of a coded video indicating that residual blocks of a current coding unit (CU) are processed with a color space conversion. The residual blocks of the current CU can include a luma residual block, a first chroma residual block, and a second chroma residual block. In response to receiving the syntax element indicating that the residual blocks of the current CU are processed with the color space conversion, one of two options of color space conversion equations can be selected based on a transform skip flag and a quantization parameter (QP) corresponding to each of the residual blocks of the current CU. An inverse color space conversion can be applied using the selected option of color space conversion equations to the residual blocks of the current CU.
