    摘要： This disclosure relates to a devices and methods related to satellite information broadcasting. Example embodiments may include frequency shifting an intermediate frequency (IF) signal down-conversion from the microwave-band. As an example, down-conversion involving local oscillators may lead to frequency drift due to varying temperature and/or humidity conditions. Correcting for the frequency drift may provide an opportunity to remove or filter excess bandwidth. Further embodiments may include receiving, in a tuning request, information about a transponder type. A frequency translation module may be adjusted based, at least in part, on the transponder type related to the IF signal being input into the frequency translation module. Such frequency-shifting and transponder-specific filtering may allow Single-Wire Multiswitch (SWM) devices to provide output signals with narrower bandwidth, which may improve signal quality, cable run length, reduce power demands, etc.

    摘要： Embodiments disclose systems and methods for variable speed playback with bi-directionality. One example implementation may comprise a computing device receiving a request to modify a playback speed of a recorded program. In response, the computing device may provide an interactive menu that enables the selection of a new playback speed for the computing device to provide the recorded program to a graphical interface (e.g., television). The computing device may further receive a selection of a given playback speed for the computing device to provide the recorded program to the graphical interface and process the video component and the corresponding audio component of the program for playout at the given playback speed. The computing device may provide the processed video component and the processed corresponding audio component in a combination for playout at the given playback speed.

    摘要： A system and method for aligning an outdoor antenna reflector unit (ODU) with multiple satellites is disclosed. The method may rely on multiple satellites as alignment anchor points to reduce ODU alignment pointing error. The method may require at least three measurements of signal power at different angles for each satellite link to determine the ODU antenna pattern for each satellite link. A peak angle is then calculated for each satellite link based on the determined satellite link ODU antenna pattern. Once the satellite link peak angles are determined, the average peak angle can be calculated and used for aligning the ODU to the multiple satellites. The method may further reduce pointing error by using satellites transmitting within the Ka frequency band as alignment anchor points. The method may simplify ODU alignment by merely requiring an installer to adjust an ODU alignment screw based on the calculated average peak angle.
