Filed:

Aug 5, 2003

Appl. No.:

10/634407

Inventors:

Justin Paul McNew - Santa Monica CA, US
Khaled I. Dessouky - Studio City CA, US
Jun Liu - Sherman Oaks CA, US

Assignee:

TechnoCom Corporation - Encino CA

International Classification:

H04Q 7/20

US Classification:

4554042, 4554561, 4554566, 455445, 455428

Abstract:

In one embodiment, the present invention is a method and system for calibrating a wireless network including a Mobile Switching Center (MSC), and a Position Determination Device (PDD). The wireless network is capable of determining the position of a handset. The method includes receiving a trigger from the MSC; sending a position request message to the PDD in response to the received trigger; receiving a position request response message from the PDD; continuously sending subsequent position request messages to the PDD in response to the same received trigger, until a termination command is received; terminating the sending subsequent position request messages, when the termination command is received; and generating output data including network calibration parameters.

Assignee:

Kapsch Trafficcom Inc. - Carlsbad CA

International Classification:

H04W 4/00

US Classification:

370338, 370350, 455411, 4554141

Abstract:

A system and method for a novel broadcasting scheme (NBS) in a wireless local area network are described, which can operate with or without a network connection. The system permits transmission of application-specific data through a specific field in a beacon frame, the Service Set Identity (SSID). By implementing a NBS Processor in an AP and a NBS Parser in stations, the AP can broadcast application-specific data while the stations can automatically act upon the receipt of the broadcast.

Appl. No.:

11/578904

Inventors:

Mark Johnson - Woodland Hills CA, US
Jun Liu - Burbank CA, US
Joseph Rice - Oakland CA, US

International Classification:

H04N 7/00
H04N 5/91

US Classification:

386096000

Abstract:

Selection of an audio-visual stream from among a plurality of streams occurs by first detecting a navigation packet within at least one stream that provides information concerning the stream, as well as those streams in lie in synchronism therewith. From the navigation packet, a determination is made which other streams lie in synchronism with the one stream, which audio and sub-picture data packets exist in each stream, and as well as which highlight information properties exist for selecting among the synchronized streams. At least one of the audio data packets, sub-picture data packets, or highlight information properties undergoes modification in accordance with information about at least one other synchronized stream to allow display of a viewer selectable button or the like to select among the synchronized streams and/or be presented with differing audio and/or sub-picture contents with each stream.
