Appl. No.:

11/138941

Inventors:

Senthil Kumar - Marlboro NJ, US
James William McGowan - Whitehouse Station NJ, US

Assignee:

Alcatel-Lucent USA Inc. - Murray Hill NJ

International Classification:

G06K 9/00
H04L 9/32

US Classification:

382100, 713176

Abstract:

A method for performing recoverable image and video watermarking which survives the use of block-based image and video compression techniques. One or more of the lowest order bits of the first DCT coefficient (the “DC” coefficient) which is to be coded are used as a “data channel” by which information representing a recoverable watermark may be embedded into an image or into a video signal frame. Encoding is performed by replacing one or more low order bits of the luminance value of each pixel in a block with a number of bits of the watermark data, and decoding is performed by averaging one or more low order bits of the decoded luminance values of the pixels in a block to retrieve a corresponding number of bits of the watermark data.

Inventors:

Mauricio Cortes - Scotch Plains NJ, US

Assignee:

Alcatel Lucent - Paris

International Classification:

H04W 36/00

US Classification:

455436, 455437, 455438, 455439

Abstract:

A method and apparatus in which a mobile network advantageously communicates data requests to neighboring data stores so that they may pre-fetch the data. In particular, in accordance with an illustrative embodiment of the present invention, a protocol is advantageously established whereby a local data store in a mobile network notifies neighboring data stores of data requests, and whereby the neighboring data stores advantageously pre-fetch the data that may be required, thereby advantageously avoiding cascading cache misses. Such notifications may advantageously reduce the number of cache misses, which in turn may advantageously reduce the latency to download data as the user moves around within the mobile network and changes data sources. Specifically, in accordance with an illustrative embodiment of the present invention, a protocol for communicating data requests between local storage centers in a network supporting mobile users is provided.

Appl. No.:

11/614371

Inventors:

Mary S. Chan - Chatham NJ, US
James W. McGowan - Whitehouse Station NJ, US
Michael C. Recchione - Nutley NJ, US

International Classification:

H04L 12/58

US Classification:

4554121

Abstract:

Methods and apparatus are provided for delivering content to a mobile terminal in a wireless network. A base station in a wireless network delivers content to a mobile terminal by determining if a packet from the mobile terminal contains a request for content; and delivering the content to the mobile terminal from the base station if the content is stored locally at the base station. The base station can optionally evaluate an authorization of the mobile terminal to receive the content. During a hand-off, the current base station determines if a packet received from the mobile terminal contains a base station change message indicating that the mobile terminal is switching to a new base station; and provides content status information (such as content position) to the new base station.

International Classification:

H04L 12/58

US Classification:

4554121

Abstract:

Methods and apparatus are provided for a virtual content channel structure in a broadband wireless network with location-based content Broadband content is delivered to a mobile terminal in a wireless network by receiving a request for a content channel from the mobile terminal; and translating the requested content channel to a corresponding content item based on the requested content channel and a date and time associated with the request (and optionally, a location of the request), wherein a content source associated with the corresponding content item is transmitted to the mobile terminal using a communication channel associated with the user The content source comprises, for example, the corresponding content item or an address or a link associated with the corresponding content item. The corresponding content item can include content components that ate based on a location of the mobile terminal.

Appl. No.:

11/978817

Inventors:

James William McGowan - Flemington NJ, US

International Classification:

H04N 7/24

US Classification:

37524002, 375E07002

Abstract:

A Multiple Bit Rate (MBR) video encoding system wherein a first video encoding at a first bit rate is performed based on the original video source material, and wherein the first video encoding generates and saves metadata relating to the encoding process. In typical block-based motion-compensated video encoding techniques, this metadata may comprise block motion search information including motion vectors and error information. This saved metadata is then used during one or more subsequent encodings at different bit rates to generate a plurality of video encodings at different bit rates. This approach provides a more efficient MBR video encoding system realization than by encoding at each bit rate independently.
