Filed:

Jun 29, 2001

Appl. No.:

09/896391

Inventors:

Luis A. Rovira - Atlanta GA

Assignee:

Scientific-Atlanta, Inc. - Lawrenceville GA

International Classification:

H04N 5445

US Classification:

725 40, 725 44, 345706, 345782, 345850

Abstract:

This invention provides a method for a subscriber television system client device to provide a three-dimensional user interface comprising a virtual reality media space. The three-dimensional user interface allows the user to navigate a three dimensional environment, participate in activities, and interact with other users. The three-dimensional user interface enables the user to associate personal characteristics with an avatar which represents the user in the system, such personal characteristics comprising a symbol, a picture, and video.

Assignee:

Scientific-Atlanta, Inc. - Lawrenceville GA

International Classification:

G06F 15/16

US Classification:

709232, 709233, 709234, 709235, 3702301, 370231, 370232, 370235, 704501, 704504

Abstract:

A device in a subscriber television system receives a stream of frames of information, and each frame of information is carried in at least one network packet that is formatted according to a first protocol. Each network packet carries an application packet that is formatted according to a second protocol, which is a protocol for an application. The device includes application awareness that enables the device to selectively modify the application packets.

International Classification:

H04J 3/16
H04N 7/173

US Classification:

370230, 370468, 725 96, 725114

Abstract:

Quality of service management in a switched digital video environment. The devices in a user's home can be given quality of service priority statuses by a system operator. In the event of oversubscription, the quality of service management allows the user to determine which services will have priority over others if more bandwidth is requested than available.

International Classification:

H04N 7/173

US Classification:

725 95, 725 96, 725 93, 725 91, 725 98, 725114, 725115, 725116, 725117, 725118, 709220, 709230, 455427, 455445, 455 121, 370352, 370328

Abstract:

Channel changes between services with differing bandwidth in a switched digital video system. A services map published by the headend and distributed to all of the edge devices, allows a bandwidth requirement to be correlated with each request from a device in the home. The bandwidth requirement is passed upstream along with the request for service and is subject to a system resource management validation.

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

H04L 12/28
H04J 3/16
H04N 7/12

US Classification:

370229, 370431, 370468, 3483901, 3484331

Abstract:

Techniques are provide herein to determine the amount of allocated and unutilized bandwidth for services already provided on each of a plurality of quadrature amplitude modulator (QAM) channels. One of the plurality of QAM channels is selected as a selected QAM channel to maximize capacity for future service requests based on a determination that the selected QAM channel can have bandwidth deallocated to support a service at a second bandwidth greater than a first bandwidth. A sufficient amount of the allocated and unutilized bandwidth is deallocated for services provided at the first bandwidth on the selected QAM channel such that the service at the second bandwidth is thereafter supportable on the selected QAM.

Neilesh R. Patel - Boston MA, US

International Classification:

H04N 7/173

US Classification:

725106, 725109, 370265

Abstract:

The present invention is directed to a videophone system implemented over a cable television network. The instant invention provides a videophone comprising a camera for capturing images associated with a videophone signal, a videophone unit and a set top terminal or cable modem connecting the videophone to a cable television network. Videophone signals created at the call origination site are encoded and transported to a predetermined destination over an existing cable television network. The system uses IP addresses as phone number on the network. Additionally, transport of videophone signals between different cable systems is accomplished via a high-speed long distance data network, such as, for example, a satellite network, that provides communication between the headends of the different cable television systems. The set top terminal may be a conventional subscriber terminal, a cable modem or a subscriber terminal configured to operate as a cable modem. The set top terminal provides the interface between the videophone and the cable television system.
