Filed: 2001-11-02
Granted: 2005-07-21
Abstract: The present invention provides an apparatus for slicing pre-pit information, which can dynamically adjust the reference voltage to slice the pre-pit information. The slicing apparatus comprises: a peak-detection unit, for detecting the peak value of the pre-pit information to generate the signal peak; a low-pass filter, for filtering the high frequency component of the pre-pit information to generate the DC signal; a calculating unit, for generating the reference voltage by adding the signal peak with the DC signal and dividing by a default value; and, a comparator, for generating the output signal by comparing the pre-pit signal with the reference voltage. Thus, the reference signal can also be dynamically adjusted even though the amplitude of the pre-pit information changes, so that the comparator can generate the correct output signal.

Title: Video transcoding apparatus and method
Inventor: LIN CHIA-WEN
IPC: H04N7/50
Filed: 2001-11-23
Granted: 2003-08-01
Abstract: A transcoder for transcoding digital video signals includes a decoder and an encoder. In the decoder, an end-of-block (EOB) position of an incoming block received by the decoder is determined and a discrete cosine transform (DCT) block type is determined based on the determined EOB position. A reduced number of DCT coefficients is computed in a subsequent inverse DCT computation based on the DCT block type. In the encoder, if the incoming block is interceded, no DCT computations are required after performing inverse quantization and re-quantization to the incoming DCT blocks. Furthermore, when the incoming block is intercoded in the encoder, an algorithm is applied to predict which DCT coefficients may become zero after a subsequent quantization operation, and only DCT coefficients that may not become zero are computed in performing the DCT computations.

IPC: G06T9/00
Filed: 2002-01-09
Granted: 2006-01-21
Abstract: Digital images have the characteristics being easily tampered. If this problem is not resolved, the popularization of digital images will be influenced. Therefore, a detection and recovery technique for tampered image is invented. The representative diagram of this method is shown in figure one, where the technology adopts a high compression rate random sampling encoding method to generate and divide authentication data. Then, the compressed code is randomly embedded into the middle frequency coefficients of original images after DCT conversion through digital watermark technology. The embedded authentication information is highly compressed, so it can be used to detect and restore the tampered images. Proved by experiment, the tampered images can be effectively detected and restored by the present invention. Also proved by experiment, the method provide remarkably robust, even when the image is cut by 90%, the restored image can still be accepted by human eyes. The tampered image detection method is proven to be effective, robust and restorable.

Abstract: A manufacturing technique for making grating features utilizes the etching characteristics for photoresist to provide desirable geometric shapes in close proximity to each other. This results in a grating for optocoupling, which is manufacturable and provides efficient coupling. A silicon waveguide is conveniently achieved using a SOI substrate so that the insulator underlying the silicon provides one material adjoining the silicon with a lower index of refraction than silicon. The top surface of the silicon has the desirable geometric shapes that result also in a lower index of refraction than silicon above the main body of the silicon substrate.
