Patent number: 9628832Abstract: 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.Type: GrantFiled: January 29, 2016Date of Patent: April 18, 2017Assignee: Cisco Technology, Inc.Inventors: Brian E. Crookes, David Verbrugge, Kenn W. Heinrich, Wayne S. Sheldrick, Keith Gammie

Patent number: 9009518Abstract: Disclosed are methods and systems of conveying and reproducing independent timebases in a network. The methods include distributing a common measurement clock and a common measurement clock counter to a plurality of cards in a master chassis in the network. Distributed master clock counters are locked to an external input signal in each of the plurality of cards. Periodic snapshots of a count value generated by the master clock counter are taken. A counter speed of the master clock counter is analyzed to create a future snapshot of the count value. The future snapshot of the count value is transmitted from the master chassis to at least one receiving chassis in the network. The association between master counters and slave counters is programmable by various means including modifying the routing of the snapshot packets.Type: GrantFiled: July 28, 2011Date of Patent: April 14, 2015Assignee: Cisco Technology, Inc.Inventor: Kenn W.

Patent number: 8432882Abstract: Systems and methods for de-combining a single combined data stream into a plurality of original data streams, where each original data stream has its own timing information, and passing respective original data steams to, e.g., one or more DVB-T modulators for broadcast into, e.g., a single frequency network. The original data streams and the single combined data stream may be, e.g., MPEG-compliant data streams.Type: GrantFiled: November 24, 2008Date of Patent: April 30, 2013Assignee: Cisco Technology, Inc.Inventors: Brian E.
