摘要： A system, method and computer program product are provided for fast channel change between logical channels within a transport multiplex. By reducing the amount of time it takes to acquire and display a tuned channel, fast channel change can improve a viewer's experience. In exemplary embodiments of the present invention, a fast channel change system can simultaneously decode channel data for each channel in a transport multiplex, reconstruct all access units for each channel and send them out on their respective channel stream in the order that each access unit completes to a streamer, store and maintain a minimum amount of channel data in a buffer in each streamer, and output channel data from a streamer corresponding to a tuned channel to a media player.

摘要： A system and method for assigning received channels to preset tuning keys of a receiver. A series of preset keys are sequentially labeled and one preset key, such as the preset key marked "0," is a pre-defined preset key. An elongated pressing of the pre-defined key causes the currently tuned channel, if it is not assigned to a preset key, to be assigned to an unassigned preset key. If the currently tuned channel is already assigned to a preset key, pressing the predefined key instead causes the currently selected channel to be un-assigned from that preset key. Radios with two tuners that each process different sets of radio signals assign channels for a particular tuner to alternating preset keys, allowing acceleration of sequentially selecting channels assigned to pre-set keys by pre-tuning another tuner to the next channel in the sequence.
摘要翻译：一种用于将接收到的频道分配给接收机的预设调谐键的系统和方法。依次标记一系列预设键，并且一个预设键（例如标有“0”的预设键）是预定义的预设键。预先定义的键的细长按压使得当前调谐的通道（如果未被分配到预设键）被分配给未分配的预设键。如果当前调谐的频道已经被分配到预设键，则按预定义的键而不是使用预设键取消分配当前选择的频道。具有两个调谐器的无线电设备，每个调谐器每个处理不同的无线电信号组，为特定的调谐器分配通道以交替预置键，允许通过将另一个调谐器预编程到下一个频道中来顺序地选择分配给预设键的频道。

摘要： Satellite earth Sensors (ES) generate scan lines, areas of detected infrared information gathered across the view of the earth by the satellite. The length of these scan lines is utilized by the satellite Attitude Control Subsystem (ACS) to determine the satellite pointing in roll and pitch. There are areas on the earth during particular periods of the year that can cause earth radiance gradient disturbance effects, satellite attitude errors caused by the ACS-calculated length of the scan lines becoming faulted. This invention includes methods and systems for minimizing disturbances to the satellite attitude for satellites in inclined, elliptical orbits that use infrared earth sensors to determine pitch and roll angles. These include identifying areas where earth radiance gradient events cause such disturbances and the prediction of times of such occurrences and methods for mitigating the effect of such events.

摘要： Systems and methods for wireless transmission of a modulated audio signal to a receiver using near-field or proximity transmission are presented. In exemplary embodiments of the present invention, such systems and methods can receive a broadcast signal with a first receiver, generate an audio signal therefrom, and then use a modulation device to convert the audio signal into a modulated signal. The modulated signal can be retransmitted wirelessly via a radiating element. The radiating element can, for example, be placed in close proximity to a second receiver, thereby enhancing the wireless link from the modulation device to the second receiver, and allowing the radiating element to operate at a relatively low power. In exemplary embodiments of the present invention, the broadcast signal can be, for example, a satellite radio signal, and the retransmission can occur within a vehicle, the second receiver being, for example, an in-vehicle conventional AM/FM radio system. In exemplary embodiments of the present invention, the radiating element can be remote from the first receiver, and can be co-located or integrated with the modulating device in a remote location. In exemplary embodiments of the present invention, a digital to analog converter can also be collocated, in-line with, or integrated with the modulating device and radiating element in the remote location.

摘要： Methods and apparatus are presented for the joint synchronization of legacy signals with overlay modulation signals in a communications system utilizing a hierarchical modulation scheme. A synchronization signal can be sent in each of the legacy and overlay bit streams, each using a different approach to frame synchronization, and the two synchronization signals can be used in a complementary manner to synchronize both bit streams. A legacy physical frame and an overlay physical frame can be aligned in time. A key synchronization signal in a legacy bit stream can be time distributed throughout a legacy transmission frame and can be utilized to assist in both the synchronization of such legacy bit stream and of an overlay bit stream. A key synchronization signal in an overlay bit stream can be sent in one fixed physical frame of an overlay transmission frame.

摘要： Systems and methods are presented for digital antenna diversity combining. In exemplary embodiments of the present invention, at least two antenna signal paths can be communicably connected to a receiver. Each antenna signal path can be provided with an RF tuner communicably connected to a demodulator, which can estimate the signal to noise ratio (SNR) and time of arrival of its respective antenna signal. In exemplary embodiments of the present invention, a time alignment circuit can be communicably connected to each antenna signal path, and a maximum ratio combiner can be communicably connected to the time alignment circuit. In operation, the time alignment circuit can use the time of arrival estimate to align the multiple signals and the maximum ratio combiner can use the SNR estimate obtained for each antenna signal to respectively weight each signal and thereby generate a combined output signal. In exemplary embodiments of the present invention, a switch diversity combiner can be further provided, and can quickly detect when an antenna signal is entering a fade, allowing the maximum ratio combiner to set that signal's weight to zero. In exemplary embodiments of the present invention, a digital diversity combiner can be provided in a stand alone integrated circuit, or can be integrated in a larger integrated circuit, such as, for example, a satellite radio overlay processor.

摘要： A modular patch antenna includes a first module and a second module. The first module comprises a first metal or metal plated radiating layer, a second, middle dielectric layer, and a third metal or metal plated ground layer; the second module comprises a frame that attaches to or fits onto the periphery of the first module and comprises a dielectric layer, or the same three layers as the first module. The first module provides favorable satellite signal reception. By superimposing the second module around the first module, the antenna provides improved terrestrial signal reception. This capability could apply to Satellite Digital Audio Radio Systems systems. This provides capability of changing the antenna gain beam direction towards the desired signals at a user's location. Users of such systems can perform this function manually.
