    摘要: Light Emitting Diodes (LEDs) are increasingly used in illumination applications. To control multiple Light Emitting Diodes (LEDs), or any other controllable light source, this document introduces a single-wire multiple-LED power and control system. Specifically, individually controlled LED units are arranged in a series configuration that is driven by a control unit located at the head of the series. Each of the individually controlled LED units may comprise more than one LED that is also individually controllable. The head-end control unit provides both electrical power and control signals down a single wire to drive all of the LED units in the series in a manner that allows each LED unit to be controlled individually or in assigned groups.

    摘要: A system and method are described for providing drift compensation for a multimedia receiver which processes multimedia streams from a plurality of satellite transponders and/or cable/broadcast carriers. In one embodiment, the average drift amount for all multimedia signals in a first group of multimedia signals is calculated and, based on the calculation, the drift of the entire group is corrected. This drift is referred to as system drift. In addition, the difference in drift between each individual multimedia signal and the system drift amount is used to correct the individual drift for each multimedia signal.

    摘要: A broadband data broadcast system that allows rich multimedia content to be delivered to a plurality of subscribers is disclosed. The broadband data broadcast system operates by multiplexing a plurality of rich multimedia digital information streams together at a centralized data broadcast center. The data broadcast center then broadcasts the multiplexed digital information stream on a broadcast medium such as satellite broadcasts, radio frequency broadcasts, or digital television broadcasts. A large number of receiver systems receive the broadcast signal and demodulate the broadcast signal to retrieve the multiplexed digital stream. The receiver system extracts a subset of digital information streams that the particular receiver system's owner has designated are of interest. The receiver system caches the interesting digital information stream for later access. The receiver system outputs the interesting digital information streams to a client system upon demand. The receiver system may also stream an incoming digital information stream to a client as the stream is received.

    摘要: A satellite ground station to receive signals with different polarization modes is described. In one example, the system includes a method of receiving a signal from a satellite at a feed, producing a first signal having a first polarization and a second signal having a second orthogonal polarization from the feed signal, and synthesizing a third signal having a third polarization different from the first and second signal and a fourth signal having fourth polarization orthogonal to the third polarization.

    摘要: Data may be encoded onto a direct current power line by modulating the current on that direct current power line. One method of modulating the current is by placing an inductor on the power line and then using a controlled transistor that turns on and turns off. The inductor will ensure that current keeps flowing but the transistor will induce changes in the current pattern. The excess current from when transistor is turned off must be diverted. Furthermore, to create symmetrical current changes, the inductor should be reverse biased. Thus, a circuit is created that sinks the excess current from when the transistor is turned off and used to reverse bias the inductor.

    摘要: An controlled LED lighting system that operates using a single conductor to power and control LED nodes is disclosed. The controlled LED lighting system modulates control data onto a nominally constant DC signal transmitted down a single conductor serial line. Nodes coupled the serial line draw power into a local capacitor and demodulate the data signal. Each node shunts the serial line when additional power is not required such that the data signal is received by every node on the serial line.
