Appl. No.:

10/215540

Inventors:

Frederick George Walls - Tustin CA, US
David M. Erickson - San Clemente CA, US
Marcus Kellerman - Aliso Viejo CA, US

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

H04N 7/26

US Classification:

386109, 386110

Abstract:

A method and apparatus are disclosed for facilitating efficient operation of trick modes in a personal video recording (PVR) system. Stream-navigation data from a data stream is captured and pre-processed to generate a frame-correlated NAV table comprising one entry for each frame within the data stream, during recording of the data stream. The stream-navigation data comprises start code data, content rating data, and conditional access data that is embedded in the data stream. During playback of the data stream in a user-selected trick mode, the frame-correlated NAV table is used to generate command packets that are sent to a data decoder along with selected frames of the data stream. The selected frames are decoded based on information in the command packets and certain selected frames may be displayed as part of the trick mode.

US Classification:

375240120, 375240250

Abstract:

A system, method, and apparatus for reducing the video decoder processing requirements are presented herein. During a rewind operation, a reference picture for a group of pictures is decoded and stored into a reference frame buffer. By storing a reference picture for the group, the reference picture need not be decoded to display each picture in the group during the rewind operation.

Inventors:

David Erickson - San Clemente CA, US
Marcus Kellerman - San Diego CA, US
Xuemin Chen - Rancho Santa Fe CA, US
Vladimir Silyaev - Laguna Niguel CA, US

International Classification:

H04N 7/173

US Classification:

725110

Abstract:

A method and/or system are described in which a server communicatively coupled with a set-top-box (STB) may predict a location of a pointer on a web browser running on the STB. The server may render the pointer based on the predicted pointer location. The server may send the rendered pointer to the STB, wherein the STB may composite a web page on the web browser based on the rendered pointer. The server may be synchronized with the STB based on event information received by the server from the STB such as, for example, keystroke events, click event, or other like event. The prediction of the pointer location may be based on actual pointer location information provided by the STB. A predetermined number of pointer locations may be predicted based on an actual pointer location and/or on a latency of a connection between the server and the STB.

International Classification:

G06F 15/16

US Classification:

709202, 709219

Abstract:

Aspects of a method and system for low-latency browsing on a device with limited processing resources are provided. In this regard, content may be retrieved and processed by a server on behalf of a client device, and the server may communicate the processed content to the client device. In processing the content, the server may process a portion of the content that will initially be displayed in a browser window by the client before processing one or more other (e.g., remaining) portion(s) of the content. The processed portion that will initially be displayed in the browser window may be communicated to the client device while a another portion of the content is processed by the server. In this manner, a user does not have to wait for an entire web page to be processed before at least a portion of the web page is viewable in the browser window.

David Erickson - San Clemente CA, US

International Classification:

G06F 15/16

US Classification:

709203

Abstract:

A STB, communicatively coupled to a server, receives a web page request when, for example, a URI, is entered into a web browser running in the STB. In response, the STB sends a processing assistance request to the server for processing the entire web page regardless of processing capability of the STB. The STB receives processed information resources or contents associated with the entire web page from the server. The server retrieves information resources or contents associated with the entire web page from a web server based on the received processing assistance request. The server determines content type such as video and/or graphics of the retrieved information resources or contents for corresponding content processing. The server determines content formats supported by the STB for content encoding. The STB decodes the resulting encoded information resources or contents from the server to render the entire web page in the STB.

US Classification:

709247

Abstract:

Certain aspects of a method and system for compression and decompression for handling web content may include a communication system that comprises a server in a server computing cloud that coordinates operation of one or more set-top boxes. The server may be operable to receive a request to display one or more frames of web content from the one or more set-top boxes. The server may be operable to receive one or more parameters associated with the one or more frames of the requested web content from the one or more set-top boxes. The server may be operable to dynamically encode at least a portion of one or more frames of the requested web content into one or more color spaces based on the received one or more parameters.

Appl. No.:

7/905042

Inventors:

David J. Erickson - Huntington Beach CA

Assignee:

O.C.A. Applied Optics, Inc. - Garden Grove CA

International Classification:

G01B 902

US Classification:

356355

Abstract:

An apparatus and method for testing variations in thicknesses of an optical part comprising an interferometer having a monochromatic light source (laser) which focuses a probe beam into the optical part being tested and detects a standing fringe pattern (Newton Fringes) arising through the interaction of two wavefronts produced by the reflection off the front and back surfaces of the optical part. These fringes may be circular or parallel depending upon the optical power of the probe beam. By observing the expansion and contractions of the interference rings, variations in the thickness of the part can be determined. By counting the number of interference peaks produced at the center of the fringe pattern, during relative movement between the optical part and the beam, a direct measurement of the optical part's thickness variations can be made. The direction of the thickness change is monitored by observing the slope of the intensity variation at the first ring of the interference pattern. A complete mapping of the variations in thickness of the part can be generated.
