Crc Checking And Error Tagging System And Method For Audio Data

View page
US Patent:
20040194001, Sep 30, 2004
Filed:
Dec 22, 2003
Appl. No.:
10/743847
Inventors:
Yao Ting - Santa Clara CA, US
Christopher Maslyar - San Jose CA, US
Xuyun Chen - San Jose CA, US
International Classification:
H03M013/00
US Classification:
714/776000
Abstract:
A method and apparatus for error detection are presented. The method includes looking for a data packet having a predetermined format and enabling an error-checking hardware module upon detecting an input data packet having the predetermined format. The incoming data frames are checked for errors and, if an error is found, an error flag is inserted in the data packet. The flagged data packets are stored in a memory unit with the error flag so that when the data frames are subsequently decoded, the flagged data frames are processed to fix the errors. The error detection apparatus includes a parsing module that looks for data frames having a predetermined format. When such data frames are located, an error-checking module becomes enabled and an error status flag is inserted in the data stream so that the decoder can decode the according to the error status flag.

Assignee:
Amlogic, Inc. - Santa Clara CA
International Classification:
G06F 17/00
US Classification:
345418
Abstract:
The present invention relates to methods for dynamically displaying an image on a display window of a digital display device, such as a digital picture frame. These methods may include the following steps: identifying one or more objects of interest in a source image; defining a crop area as a function of the one or more objects of interest; decoding the crop area of the source image into a canvas image; and displaying the selected area of the canvas image.

Methods For Dynamically Displaying Digital Images On Digital Display Devices

US Patent:
20090295789, Dec 3, 2009
Filed:
Jun 3, 2008
Appl. No.:
12/132586
Inventors:
Ting Yao - San Jose CA, US
Xuyun Chen - San Jose CA, US
Jiping Zhu - San Jose CA, US
Michael Yip - Los Altos CA, US
Assignee:
Amlogic, Inc. - Santa Clara CA
International Classification:
G06F 17/00
US Classification:
345418
Abstract:
The present invention relates to methods for dynamically displaying images on a display window of a digital display device such as a digital picture frame. These methods include the steps of: processing the source image into a canvas image having canvas pixels as a function of the source image characteristics; upon the canvas image meeting one or more conditions for the panning of an image, selecting a panning velocity for the canvas image; defining a viewing window with respect to the canvas image wherein said viewing window having a viewing image, said viewing image is to have a plurality of viewing pixels; calculating the viewing pixels for said viewing image; displaying said viewing image for said viewing window on said display window; redefining said viewing window with respect to the canvas image as a function of said panning velocity; and repeating the calculating and displaying steps for said viewing window. These methods allow for the dynamic display of images with special effects on a digital display device as a function of the properties of the image (e.g. a panoramic image). They also provide for the smooth panning of digital images at velocities that are accurate up to fractional pixels per unit time.

Decoding System And Method

US Patent:
20040193289, Sep 30, 2004
Filed:
Dec 22, 2003
Appl. No.:
10/743850
Inventors:
Shi Chen - San Jose CA, US
Xuyun Chen - San Jose CA, US
Christopher Maslyar - San Jose CA, US
International Classification:
G05B019/18
US Classification:
700/003000
Abstract:
A cost-effective decoding apparatus that balances the flexibility of the software and performance of the hardware is presented. The decoder includes a bus, hardware modules connected to the bus and configured to execute a decoding process, and a processing unit connected to the bus, wherein the processing unit executes a decoding process by sending programmed signals to the hardware modules and responding to interrupts from the hardware components according to a set of programmed instructions. The instructions are re-programmable. As the hardware modules are configured to execute discrete tasks, the decoding process may be carried out in its entirety by sending signals to the hardware modules in the programmed order. Also presented is a method of decoding data by establishing communication with hardware modules that are each configured to execute a discrete task and activating the hardware modules in an order dictated by a computer program is also presented.
