    • A system and method for receiving services is presented. The system comprises a first splitter having an input, a first output and a slaved output receiving a first signal at the input having a single polarization including a first service and a slaved service, wherein the first signal is directed to the first output and the slaved output and selected by a first control signal applied at the input, a first tuner receiving the first output and tuning the first service and a slaved tuner receiving the slaved output and tuning the slaved service.. The method comprises generating a first control signal to select a first signal, receiving a first signal including a first service and a slaved service, wherein the first service and the slaved service are at the same polarization, splitting the first signal with a first splitter to a first output and a first slaved output, tuning the first service from the first output with a first tuner and tuning the slaved service from the slaved output with a slaved tuner.
    • 提出了一种接收服务的系统和方法。 该系统包括具有输入,第一输出和从输出的第一分离器,其在输入处接收具有包括第一服务和从属服务的单一极化的第一信号,其中第一信号被引导到第一输出和从属 输出并通过在输入端施加的第一控制信号选择,第一调谐器接收第一输出并调谐第一服务;以及从属调谐器,接收从属输出并调整从属服务。该方法包括生成第一控制信号以选择 第一信号,接收包括第一服务和从服务的第一信号,其中第一服务和从服务处于相同的极化,将第一信号与第一分离器分离成第一输出和第一从动输出,调谐 从第一个输出的第一个服务与第一个调谐器,并从奴隶的输出调整奴隶服务与奴隶的调谐器。

    • A method and system for detecting satellite signal lock in a satellite receiver system is disclosed. The system may include a first filter that isolates a noise frequency from the satellite signal, and/or a second filter that isolates a service frequency from the satellite signal. A comparator may then determine whether the output of the first and/or second filters is greater than a threshold level associated with an incipient loss of lock on the broadcast signal. The method includes the steps of filtering a received broadcast satellite signal to generate a service signal having a center frequency between a first transponder center frequency of a first transponder band and a second transponder center frequency of a second transponder band that overlaps the first transponder band, and comparing the output of the filter to a threshold value. In either the method or the apparatus, a command may be issued if the signal value is below the threshold value, thereby informing the user of the loss of signal lock.
    • 公开了一种在卫星接收机系统中检测卫星信号锁定的方法和系统。 该系统可以包括将噪声频率与卫星信号隔离的第一滤波器和/或将卫星信号隔离服务频率的第二滤波器。 然后,比较器可以确定第一和/或第二滤波器的输出是否大于与广播信号上的锁定的初始丢失相关联的阈值电平。 该方法包括以下步骤:过滤所接收的广播卫星信号以产生具有第一应答器频带的第一应答器中心频率和与第一应答器频带重叠的第二应答器频带的第二转发器中心频率之间的中心频率的服务信号, 以及将所述滤波器的输出与阈值进行比较。 在方法或装置中,如果信号值低于阈值,则可以发出命令,从而向用户通知信号锁定的丢失。
