Filed:

Oct 20, 2000

Appl. No.:

09/693351

Inventors:

Wei Ding - Fremont CA, US
Andy C. Hung - Los Altos CA, US

Assignee:

Intervideo, Inc. - Fremont CA

International Classification:

H04N005/21

US Classification:

348448

Abstract:

A system and method for processing a video signal to make the corresponding image suitable for display on a progressive display device, i. e. , a computer monitor, is disclosed. The processing system includes a video display module which is capable of processing an image frame based on the content of the frame information itself, or the values of the pixels that comprise the frame.

Abstract:

An array of DCT transform coefficients are converted to a two-dimensional array of spatial data in a video compression or decompression system. The array of DCT transform coefficients are divided into two groups. A regional IDCT algorithm is applied to all coefficients, both non-zero and zero, of the first group, while IDCT computation is applied to only non-zero coefficients of the second group. The results of the operations are then combined and/or mapped to form the output array of spatial data. In one specific implementation wherein an 8. times. 8 array of DCT coefficients are to be transformed, the first region is defined by the first quadrant of coefficients in the 8. times. 8 array. A regional IDCT algorithm is applied to both zero and non-zero coefficients in the first quadrant. The non-zero coefficients in the remaining three quadrants are calculated directly, and the results of the direct calculations are combined with the results of the regional IDCT algorithm applied to the first quadrant coefficients.

Abstract:

Human coronary heart disease susceptibility gene (CHD1), some alleles of which are related to susceptibility to coronary heart disease. Germline mutations in the CHD1 gene and their use in the diagnosis of predisposition to coronary heart disease and to metabolic disorders, including hypoalphalipoproteinemia, familial combined hyperlipidemia, insulin resistant syndrome X or multiple metabolic disorder, obesity, diabetes and dyslipidemic hypertension. Presymptomatic therapy of individuals who carry deleterious alleles of the CHD1 gene (including gene therapy, protein replacement therapy, and administration of protein mimetics and inhibitors). The screening of drugs for dyslipidemic therapy.

Abstract:

Motion vectors and associated errors which are determined in the course of encoding a video signal are used to determine whether respective macroblocks of two or more frames represent the same subject matter albeit displaced by motion represented by the frames. The motion vector errors are compared to a predetermined motion threshold. If a particular motion vector error is less than the motion threshold, the macroblocks corresponding to the motion vector error are determined to represent substantially identical subject matter and the corresponding motion vector represents displacement of the subject matter between the frames due to motion of the subject matter. Accordingly, differences between the macroblocks corresponding to the motion vector error are determined to be due primarily to noise and not to differences in the subject. Therefore, a relatively heavy temporal filter is applied between the macroblocks. Conversely, if a particular motion vector error is not less than the motion threshold, the macroblocks corresponding to the motion vector error are determined to represent different subject matter and only a spatial filter is applied to either macroblock.

Abstract:

The present disclosure describes storage techniques for hybrid transactional and analytical processing. Data captured by a first processing engine may be received. The first processing engine may be configured to perform online transactional processing). Multiple replicas of logical logs generated based on the data may be distributed to a Delta Store by applying a quorum protocol on the multiple replicas. Data in the Delta Store are stored in a row format and are visible to a query for online analytical processing performed by a second processing engine. Data may be flushed from the Delta Store to a Base Store based on one or more predetermined rules. Data in the Base Store are stored in a columnar format and may be accessible by the second processing engine.
