Filed:

Jul 25, 2006

Appl. No.:

11/492383

Inventors:

Shu Lin - Cerritos CA, US

Assignee:

Communications Coding Corporation - Cerritos CA

International Classification:

G06F 11/00
H03M 13/00

US Classification:

714800

Abstract:

The universal forward error-correction coding system provides adjustable code rates and coding gains to greatly benefit the design of many modern digital communications (data storage) systems. The channel encoding and decoding methods are universal such that a single encoder and a single decoder can be used to implement all the forward error-correction codes of different code rates. This universal forward error-correction coding system also includes a novel systematic code generation procedure that has the capability of generating many classes of codes that provide the best balance between coding gain performance and implementation complexity.

US Classification:

482 8, 482 1, 482 9, 463 1, 463 7

Abstract:

A system for encouraging a user to perform substantial physical activity. The system may include sensors that may be worn by the user while the user is performing a substantial physical activity, such as running or playing basketball. The sensors may detect the magnitude of the physical activity and may transmit data regarding the physical activity to a processing system. The processing system may display a reward to encourage the user for participating in physical activity and the reward provided may be based on the physical activity of the user.

International Classification:

G06F 11/00

US Classification:

714758

Abstract:

The Universal Packet Loss Recovery System is capable of recovering end-to-end network packet losses to obtain reliable end-to-end network delivery of multimedia streaming content over Internet Protocol (IP) networks, where packet losses appear above the transport layer. This system incorporates the use of Packet Forward Error Correction Coding (FEC) with packet interleaving processing prior to transport. Packet FEC Coding is an error correction coding method at the packet level which improves link transmission reliability. At the source end of the packet-switching network, the Packet FEC Coding scheme encodes a stream of transport multimedia content packets by including redundant packets to allow for recovery of lost packets by the Packet FEC Coding decoder at the user end of the packet-switching network. Since lost packets appear only above the transport layer in the IP network protocol stack, Packet FEC Coding can be viewed as a transport layer or application layer coding method.
