Abstract: A method and apparatus for video encoding or decoding used by a video encoder or decoder respectively. In one method, input data associated with a video sequence are received. A current sequence header for a current picture is determined. Whether the current sequence header corresponds to a first sequence header or a second sequence header is determined. If the current sequence header corresponds to the second sequence header, one or more syntax values of a syntax set associated with the first sequence header are assigned to corresponding one or more syntax values of the syntax set associated with the current sequence header. The current picture is then encoded or decoded according to the current sequence header.

Abstract: Aspects of the disclosure provide a video decoding system. The video decoding system can include a decoder core configured to selectively decode independently decodable tiles in a picture, each tile including largest coding units (LCUs) each associated with a pair of picture-based (X, Y) coordinates or tile-based (X, Y) coordinates, and memory management circuitry configured to translate one or two coordinates of a current LCU to generate one or two translated coordinates, and to determine a target memory space storing reference data for decoding the current LCU based on the one or two translated coordinates.

Abstract: A method and apparatus of reusing reference data for video decoding are disclosed. Motion information associated with motion vectors for coded blocks processed after the current block are derived without storing decoded residuals associated with the coded blocks. Reuse information regarding reference data required for Inter prediction or Intra block copy of the coded blocks is determined based on the motion information. If the current block is coded in the Inter prediction mode or the Intra block copy mode, whether required reference data for the current block are in an internal memory is determined and the reference data are fetched from an external memory to the internal memory if the required reference data are not stored in the internal memory. The reference data in the internal memory is managed according to the reuse information to reduce data transferring between the external memory and the internal memory.

Abstract: An abrasive tool having a spray-formed brazing filler layer and a manufacturing process thereof are described, in which drawing and adhering steps performed on a conventional brazing filler layer are simplified through spraying. A solvent, an adhesive, and a powder are sequentially mixed to form a brazing filler slurry; next, the brazing filler is sprayed on a substrate, so as to form a brazing filler layer with an appropriate thickness; and then, abrasive particles are adhered to the brazing filler layer, and then the abrasive particles are combined with the substrate through the brazing filler layer by brazing. The conventional drawing and adhering steps are omitted through spraying, and it is applicable for substrates with complicated shapes.

Abstract: A ceramic polishing pad dresser and the method for fabricating the same are provided. Abrasive particles are adhered onto a ceramic substrate by heating a ceramic powder to be vitrified, thus forming a ceramic diamond disk. Meanwhile, a plastic base is mounted on the bottom of the ceramic diamond disk. As for heating the ceramic powder to be vitrified, the ceramic powder with low melting point is disposed on the ceramic substrate, and to be heated to form a vitrified adhering layer, so as to adhere the abrasive particles disposed thereon to the ceramic substrate. The plastic base mounted on the bottom of the ceramic diamond disk is provided for bearing the ceramic diamond disk and has corresponding screw holes and positioning holes formed thereon for fitting the chemical mechanical polishing table to be mounted and reducing the manufacturing cost.
