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.
