    • 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。
