Patent number: 10015052Abstract: Different data communication architectures receive a wide variety of content, including audio and video content, for consumers. The architectures employ channel bonding to deliver more bandwidth than any single communication channel can carry. In some implementations, the communication architectures receive distributed video programming in the form of MPEG2 TS packets, flagged by marker packets. Channel bonding synchronization information may be present in packets defined above the data-link layer or received in fields within data-link layer frames.Type: GrantFiled: November 24, 2015Date of Patent: July 3, 2018Assignee: AVAGO TECHNOLOGIES GENERAL IP (SINGAPORE) PTE.

Patent number: 9843379Abstract: A method and apparatus is disclosed to restrict the delivery of video, audio, and/or data to unauthorized end users in a satellite communications system. The satellite communications system includes one or more satellite receiving antennas, commonly referred to as a satellite dish, to receive downlink communications signals from one or more satellites. The transmission received by the one or more satellite receiving antennas is converted by an outdoor unit (ODU) for transmission to one or more indoor units (IDUs). The ODU receives control information from one or more satellites from the downlink communications signals, commonly referred to as in-band, and/or from out-of-band communications signals. The ODU may use the control information to restrict access to one or more communications channels embedded within the downlink communications signals to the unauthorized end users.Type: GrantFiled: March 23, 2015Date of Patent: December 12, 2017Assignee: Avago Technologies General IP (Singapore) Pte.

Patent number: 9197366Abstract: FEC (Forward Error Correction) decoder with dynamic parameters. A novel means by which FEC parameters may be encoded into, and subsequently extracted from, a signal stream to allow for adaptive changing of any 1 or more operational parameters that govern communications across a communication channel. FEC parameters are encoded directly into a data frame such that the data frame is treated identical to all other data frames within the signal stream. When the data frame actually includes FEC parameters, it is characterized as a CP (Control Packet) type. For example, when decoding an MPEG stream, an MPEG block that includes FEC parameters, that MPEG block is characterized as a CP MPEG block. The means by which FEC parameters are encoded and extracted from the signal stream allows for much easier adaptive modification of the manner by which signal are encoded, modulated, and processed within a communication system.Type: GrantFiled: July 8, 2013Date of Patent: November 24, 2015Assignee: BROADCOM CORPORATIONInventors: Hiroshi Suzuki, Alan Y.

Patent number: 9032453Abstract: A multiplexed transport interface (MTSIF) may be utilized during communication between a demodulation module and a video processing system-on-chip (SoC). The MTSIF may enable concurrent demodulation of a plurality of input modulated video streams, via a plurality of demodulator chips within the demodulation module, by multiplexing data generated by the demodulator chips via the MTSIF during communication between the demodulator module and the video processing SoC. The MTSIF may also be utilized for communicating control signals, which may be used in controlling and/or managing operations of the demodulation module, the video processing SoC, and/or the MTSIF. Communication via the MTSIF may be synchronized. Packets communicated via the MTSIF may be timestamped. Timestamp counters may be used in the demodulation module and the video processing SoC to generate and/or track timestamps in communicated packets. The timestamp counter may be synchronized, using control signals communicated via the MTSIF.Type: GrantFiled: July 29, 2013Date of Patent: May 12, 2015Assignee: Broadcom CorporationInventors: Rajesh Mamidwar, Stephen Edward Krafft

Patent number: 8520756Abstract: Physical layer (PHY) sub-channel processing. A soft symbol decision stream is arranged into a number of sub-channels to reduce substantially the processing performed within a communication receiver on data that is not intended for that communication receiver. In other embodiments, a predetermined approach is employed to arrange the soft symbol decision stream into one or more frames; each frame may have one or more soft symbol blocks; and each soft symbol block may have one or more symbols. Each of the soft symbol blocks, within a frame, may be assigned to a sub-channel. Only the soft symbol blocks that contain information destined for the communication receiver need be decoded. Only the sub-channel that includes these soft symbol blocks, destined for this communication receiver, need be decoded. The soft symbol blocks not within the sub-channel may be discarded thereby recovering some of the processing capabilities of the communication receiver.Type: GrantFiled: August 22, 2012Date of Patent: August 27, 2013Assignee: Broadcom CorporationInventors: Steven T.
