Abstract: Systems and methods are disclosed for enabling a switched digital video (SDV) client to intelligently generate and transmit reverse request in a SDV system. In this manner, reverse channel traffic is reduced. During rapid channel changes using the up and down keys on a remote control, the SDV client waits a predetermined amount of time before generating a reverse request that is subsequently transmitted upstream to a headend server. By way of example, changing broadcasted channels quickly will not generate a reverse request until the predetermined amount of time is over. In the event that a changed channel is an SDV session, a program select request is immediately generated in order to begin receiving the SDV session.

Abstract: Disclosed is a receiver system, capable of receiving RF signals on television channels of multiple bandwidths. The receiver system includes a tuner, an analog IF filter, an ADC, a mixer module, one or more digital filters, an AGC module and a controller. The tuner converts an RF signal into an IF signal using a mixer frequency. The analog IF filter filters out a fixed band signal from the IF signal. The ADC module converts the fixed band signal into a digital signal, which is filtered by digital filters. The output of the digital filters is converted to a base band signal and the power level of the base band signal is controlled by the AGC module. The controller selects a mixer frequency from a group of mixer frequencies based on a function of power of the output of the AGC module by applying each mixer frequency to the tuner.
