| 20080284906 | Devices and Methods for Transforming Coding Coefficients of Video Signals - Disclosed are a device and a method for transforming a first coding coefficients of video signals into a second coding coefficients of the video signals. The device includes a first storing means for storing the first coding coefficients; a second storing means for storing a transform matrix; a multiplication means for multiplying the first coding coefficients by coefficients of the transform matrix; an addition means for adding each of values resulted from the multiplication operation of the multiplication means to form a sum; and a shifting means for shifting the sum to obtain the second coding coefficients. According to the present invention, signals compressed by various transforms may be transformed to each other, so as to make various compression signals compatible. Thus, the signals can be compatible with more standards and are more universal. | 11-20-2008 |
| 20090112958 | Processes and apparatus for deriving order-16 integer transforms - Apparatus, systems and techniques based on an integer transform for encoding and decoding video or image signals, including apparatus, systems and techniques for deriving an order-16 integer transform from an order-8 integer transform in image and video coding. In some implementations, eight additions and eight subtractions are used to assign the data elements to be transformed to an intermediate matrix; and then two fast algorithms for the computation of the order-8 transform may be applied to the first 8 vectors of the intermediate matrix, and the last 8 vectors of the intermediate matrix, respectively. The derived order-16 integer transform tends to produce small magnitude and high frequency transformed coefficients, and thus achieve high compressibility. | 04-30-2009 |
| 20090257504 | Methods and Apparatus for Deriving an Order-16 Integer Transform - Apparatus, systems and techniques based on an integer transform for encoding and decoding video or image signals, including an order-16 integer transform from a Microsoft Media Video order-8 integer transform with a high energy-packing ability and an improved data compression in the field of image and video coding. For example, a method and an apparatus are provided for deriving an order-16 integer transform from an order-8 integer transform in the standard transform of Microsoft Media Video. Eight additions and eight subtractions are used to assign the data elements to be transformed to an intermediate matrix; and then two fast algorithms for the computation of the order-8 transform may be applied to the first 8 vectors of the intermediate matrix, and the last 8 vectors of the intermediate matrix, respectively. The derived order-16 integer transform tends to produce small magnitude and high frequency transformed coefficients, and thus achieve high compressibility. | 10-15-2009 |

| 20100314477 | Multi-Purpose Solid Material Grinder - This utility patent is a multi-purpose solid material grinder. It includes a shell. The interior space of shell is divided into two or more than two chambers. Each chamber has its own container chamber and grinding set. On the shell of each chamber there is inlet hole and outlet hole for each container chamber. In the shell there is also a motion changing set that will drives every grinding unit's grinding driving axis to operate, and a driving set that will drives the motion changing set to pass the motion to the motion units. By separating the interior of the shell into several grinding chambers, and put containing chamber and grinding mechanism inside each grinding chamber separately, the grinder contains several independent grinding system, which can grind different solid materials. And by engaging the motion changing set, different grinding systems share a driving unit that have one power input. Thus it is very convenient. | 12-16-2010 |
