Louise Elizabeth Moser has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Forward error correction method
    Patent number: 8473833
    Abstract: This invention concerns packet recovery for real-time (live) multi-media communication over packet-switched networks like the Internet. Such communication includes video, audio, data or any combination thereof. The invention comprises forward error correction (FEC) algorithms addressing both random and burst packet loss and errors, and that can be adjusted to tradeoff the recoverability of missing packets and the latency incurred.
    Type: Grant
    Filed: May 22, 2012
    Date of Patent: June 25, 2013
    Assignee: Nevion USA, Inc.
    Inventors: Peter Michael Melliar-Smith, Louise Elizabeth Moser, Chin Chye Koh

  • Forward error correction for burst and random packet loss for real-time multi-media communication
    Patent number: 8230316
    Abstract: This invention relates generally to a packet recovery algorithm for real-time (live) multi-media communication over packet-switched networks, such as the Internet. Such multi-media communication includes video, audio, data or any combination thereof. More specifically, the invention comprises a forward error correction (FEC) algorithm that addresses both random and burst packet loss and errors, and that can be adjusted to tradeoff the recoverability of missing packets and the latency incurred. The transmitter calculates parity packets for the rows, columns and diagonals of a block of multi-media data packets using the exclusive or (XOR) operation and communicates the parity packets along with the multi-media data packets to the receiver. The receiver uses the parity packets to recover missing multi-media data packets in the block. The FEC algorithm is designed to be able to recover long bursts of consecutive missing data packets.
