Adaptive Joint Source And Channel Coding Scheme For H.264 Video Multicasting Over Wireless Networks

US Patent:
8089892, Jan 3, 2012
Filed:
Dec 15, 2005
Appl. No.:
12/086458
Inventors:
Zhengye Liu - Brooklyn NY, US
Hang Liu - Yardley PA, US
Yao Wang - Matawan NJ, US
Assignee:
Thomson Licensing - Boulogne-Billancourt
International Classification:
H04L 1/00
US Classification:
370252, 709224
Abstract:
A method and apparatus for estimating packet loss rate are described including calculating a real packet loss rate in a time slot at the end of the time slot, estimating average packet loss rate for a subsequent time slot, estimating variance of packet loss rate for the subsequent time slot and estimating the packet loss rate for the subsequent time slot. A method and apparatus and also described for dynamically allocating available bandwidth for video multicast including selecting an intra-frame rate, determining a packet loss rate threshold, receiving user topology information, receiving channel conditions for each user, determining an optimal operation point for encoding and transmitting video frames in a subsequent time slot, adapting dynamically quantization parameters and a forward error correction code rate, encoding the video frames using the quantization parameters and applying forward error correction code with the forward error correction code rate to data packets of the video frames to generate forward error correction packets.

Adaptive Joint Source And Channel Coding Scheme For H.264 Video Multicasting Over Wireless Networks

US Patent:
2012009, Apr 19, 2012
Filed:
Nov 16, 2011
Appl. No.:
13/297942
Inventors:
Zhengye LIU - Brooklyn NY, US
Hang LIU - Yardley PA, US
Yao WANG - Matawan NJ, US
International Classification:
H04W 24/00
US Classification:
370252
Abstract:
An invention is described including calculating a real packet loss rate in a time slot at the end of the time slot, estimating average packet loss rate for a subsequent time slot, estimating variance of packet loss rate for the subsequent time slot and estimating the packet loss rate for the subsequent time slot.

Efficient Application-Layer Automatic Repeat Request Retransmission Method For Reliable Real-Time Data Streaming In Networks

US Patent:
2012017, Jul 5, 2012
Filed:
Oct 7, 2009
Appl. No.:
13/395796
Inventors:
Ramkumar Perumanam - Edison NJ, US
Ishan Uday Mandrekar - Monmouth Junction NJ, US
Mingquan Wu - Princeton Juntion NJ, US
Hang Liu - Yardley PA, US
Saurabh Mathur - Monmouth County NJ, US
International Classification:
H04L 12/24
US Classification:
370216
Abstract:
A method and apparatus are described including buffering data to be transmitted, transmitting data retrieved from a buffer via a datagram protocol, receiving a request for retransmission of data, determining if the requested data is in the buffer and retransmitting the requested data via a protocol that provides end-to-end acknowledgement of data and error recovery.

Method And Apparatus For Enabling Access To Applications Integrated With A Visited Network

US Patent:
2013008, Apr 4, 2013
Filed:
Sep 28, 2012
Appl. No.:
13/630523
Inventors:
Xavier De Foy - Kirkland, CA
Yousif Targali - Cliffwood NJ, US
Kamel M. Shaheen - King of Prussia PA, US
Hang Liu - Yardley PA, US
Milan Patel - Harrow, GB
Osama Lotfallah - King of Prussia PA, US
Assignee:
INTERDIGITAL PATENT HOLDINGS, INC. - Wilmington DE
International Classification:
H04W 12/06
US Classification:
455411
Abstract:
A method and apparatus for interworking between a mobile network operator and an application provider are disclosed. A network application function (NAF) may be co-located with an OpenID provider such that an application server may communicate with the NAF to access a home subscriber server (HSS) via a bootstrapping server function (BSF). The interfaces between BSF and HSS, and between BSF and NAF may be enhanced to carry information that is available through Sh interface between the application server and the HSS. When the WTRU is roaming in a visited network, the application server may communicate with the visited network for charging and policing for serving the service request from the WTRU. The application server may be co-located with an NAF, and may authenticate the WTRU using Generic Bootstrapping Architecture, and may communicate with a BSF in a home network via an eZn-proxy function to access an HSS.
