Model:

CR-V

Year:

2007

US Patent:

7729426, Jun 1, 2010

Filed:

Sep 20, 2005

Appl. No.:

11/230794

Inventors:

Cheng Huang - Irvine CA, US

Assignee:

DIVX, Inc. - San Diego CA

International Classification:

H04N 7/12
G06K 9/40

US Classification:

37524029, 382264

Abstract:

Deblocking filters are disclosed, where the nature of the filter is determined based upon the level of detail of a reconstructed video frame in the region in which the block boundary is located. One embodiment of the method of the invention includes identifying a boundary between two blocks of the reconstructed video frame, determining the level of detail of the reconstructed video frame in a region in which the block boundary is located, wherein the region includes pixels from multiple rows and multiple columns of the reconstructed video frame and includes at least one pixel that is not immediately adjacent the block boundary and selecting a filter to apply to predetermined pixels on either side of the block boundary based upon the determined level of detail.

Abstract:

A device, a circuit, and a method for current bypass are provided. The device includes circuitry detects an overload condition at a switching regulator output, enables a current bypass path including a linear current source in response to detecting the overload condition, and digitizes a difference between a load current and a switching regulator output current. The linear current source generates an active current assist signal based on the digitized difference between the load current and the switching regulator output current.
