20090143680 | METHOD AND APPARATUS FOR SCAN CONVERSION AND INTERPOLATION OF ULTRASONIC LINEAR ARRAY STEERING IMAGING - A method and apparatus for scan conversion and interpolation of linear array steering imaging in an ultrasonic system are disclosed. The method computes the points that are most related to the point to be interpolated in the principal direction of the point spread function and performs interpolation in the principal direction of the point spread function according to the steering angle of the scan lines so as to obtain a more accurate interpolation result. | 06-04-2009 |
20090313667 | METHOD, DEVICE AND SYSTEM FOR MANAGING CONTENTS OF VOD SERVICES - A method for managing contents of Video On Demand (VOD) services, where a Middle Ware (MW) controls the stored contents on a VOD server according to the VOD service information correlated with a channel is provided. The corresponding device and system are also provided. Therefore, the specific service forms are separated from the stored contents, and the MW controls the contents in a centralized manner according to the service information; the VOD server does not need to store the contents of each service separately, but adds and deletes the stored contents according to the unified control from the MW, thus avoiding repeated storage of the same data for different services. | 12-17-2009 |
