  • Method and system for digital video broadcast for cable (DVB-C2)
    Patent number: 9380350
    Abstract: Methods and systems for DVB-C2 are disclosed and may include receiving data encoded utilizing variable encoding, variable modulation and outer codes via a physical layer matched to a desired quality of service. An error probability may be determined for said received data and retransmission of portions of said data with error probability above an error threshold may be requested. The variable modulation may include single carrier modulation, orthogonal frequency division modulation, synchronous code division multiple access, and/or from 256 QAM to 2048 QAM or greater. The variable encoding may include forward error correction code, which may include low density parity check code.
    Type: Grant
    Filed: May 6, 2013
    Date of Patent: June 28, 2016
    Assignee: BROADCOM CORPORATION
    Inventors: Thomas J. Kolze, Robbert van der Wal, Bruce J. Currivan
