  • Patent number: 9628832
    Abstract: Systems and methods for combining a plurality of transport streams into a single transport stream for transmission to, e.g., a single frequency network via a satellite. Embodiments provide receiving a plurality of original, e.g., MPEG-compliant, data streams, where each original data stream has its own timing information, combining the plurality of original data streams into a single combined data stream which is also, e.g., MPEG compliant, modulating the single combined data stream for uplink to a satellite, receiving a downlink transmission from the satellite, where the downlink transmission includes the single combined data stream, de-combining the single combined data stream into the plurality of original data streams, and passing respective original data steams to, e.g., one or more DVB-T modulators for broadcast into a single frequency network.

  • Patent number: 8265139
    Abstract: A packet comparator includes a match packet buffer and a first in first out (FIFO) buffer that stores a reference packet stream. Once a packet in the reference stream and a candidate stream are matched to the match packet, the reference stream and the candidate stream are considered synchronized. Thereafter, the two streams are passed through a compare function and a resultant stream is output from the packet comparator. Possible resultant streams include the results of an exclusive OR (XOR) operation between all, or selected parts, of packets in each of the streams.

  • Patent number: 7957423
    Abstract: A method for correcting packet errors in a combined stream including steps of receiving a combined and re-packetized transport stream comprising program information for at least two transport streams (A and B), wherein each transport stream (A and B) comprises program information associated with respective distinctive packet IDs (PIDs), detecting an invader packet associated with the combined and re-packetized transport stream A does not belong in the combined and re-packetized transport stream A, offering the invader packet to combined and re-packetized transport stream B in which a gap is detected, and de-combining combined and re-packetized transport stream B such that information from a de-combined version of the invader packet fills a gap in a de-combined version of combined and re-packetized transport stream B.

  • Publication number: 20070029713
    Abstract: A control circuit for an active engine mount is provided, including an electrical bridge circuit, and a pulse-width modulation (‘PWM’) circuit. The PWM circuit receives an input signal from a controller, and generates first and second PWM output signals. The first PWM signal, derived from the input signal, controls first and third switches of the electrical bridge circuit. The second PWM signal comprises a digitally inverted signal of the first PWM signal, and controls second and fourth switches of the electrical bridge circuit. First and second outputs of the bridge circuit are connectable to first and second terminals of the mount device. The controller receives an input signal from crank and cam sensors, as part of the control scheme.
