  • Patent number: 8934833
    Abstract: A fast and efficient automated satellite constellation detection process can be implemented at least in part independent of in-band data in the satellite signal. The automated detection process iterates through a set of various predefined transponder settings to detect one or more accessible satellite constellations through each satellite dish connected directly or through a switch to a satellite receiver. The process determines whether the satellite receiver is able to lock onto a satellite signal at each transponder setting. Based on the combinations of which satellite constellations are available at each transponder setting, the process allocates a specific satellite constellation to each satellite dish. In one implementation, channel information can be used to further refine the detection and identification of accessible satellite constellations for each satellite dish.

Such event trigger data strings may be added to many different digital content streams, and a router or switching component may distribute the streams to systems that disseminate them to the audience. The technique enables interaction with different event sources, and allows command of multiple different operations by these event sources.

  • Patent number: 8689263
    Abstract: A frequency translation module for delivering satellite signals to Integrated Receiver Decoders (IRDs). The module comprises at least one input for receiving polarized satellite signals, wherein at least one input is coupled to at least one low noise block amplifier (LNB), at least one legacy output, the legacy output coupled to the input through a multiswitch, wherein each legacy output selects a polarization of a satellite signal based on a Legacy IRD command directly to the multiswitch, and at least one combined output, the combined output coupled to the multiswitch through an interface, wherein at least one new IRD selectively commands the frequency translation module such that each new IRD receives a portion of a satellite signal based on commands received from each IRD.

  • Patent number: 8683531
    Abstract: According to an exemplary embodiment of the invention, a digital data stream is divided into at least two complementary digital substreams and delayed in time. The first digital substream and the second digital substream are transmitted by the broadcasting systems with a time offset in accordance with the broadcasting principle such that any receiver can use the respectively intact part of the other complementary digital substream in order to ensure a seamless media reception when a break in the transmission or reception occurs.

  • Patent number: 8656436
    Abstract: Various designs of configurable multiswitch or multifeed satellite reception systems comprising switch-over matrices and transponder branches and “one cable solutions” which allow or do not allow subsequent expansion with respect to the subscribers that can be connected thereto are known from the prior art. In general, the costs for such systems comprising frequency converters are primarily determined by the frequency converters and the associated filters. The aim of the invention is to devise inexpensive methods or devices which allow detection of the complete frequency spectrum—even after subsequent expansions—and which therefore do not involve any restrictions with respect to the program range.

  • Publication number: 20130332968
    Abstract: A signal receiver may be configured to determine when signal generation changes affecting signals being received by the signal receiver may cause performance related changes; and to modify its (the signal receiver) configuration to handle the performance related changes. In this regard, the modifying of configuration may comprise determining characteristics of performance related changes, and controlling operations of the signal receiver based on the determined characteristics of the performance related changes. The performance related changes may comprise amplitude glitches, phase glitches, and/or bit or packet errors. The signal generation changes may comprise channel-to-frequency re-assignment. Controlling operations of the signal receiver based on determined characteristics of the performance related changes may comprise adjusting such parameters as amplification gain and/or tracking loop bandwidth, and/or determining whether (or not) to ignore bit/packet errors—i.e. not reacquire (e.g.

  • Publication number: 20130318557
    Abstract: An apparatus for detecting spectrum inversion includes a different correlator and a determining module. The differential correlator performs an odd-order differential correlation on an input signal and a known signal to generate a differential correlation result. When the input signal is determined as corresponding to a target signal of the known signal, the determining module detects spectrum inversion in the input signal according to the phase of the differential correlation result.
