Abstract
An access point of a wireless network broadcasts directory information including a schedule on a first broadcast channel about media programs being broadcast on other channels by the access point. The broadcast on the first channel provides for sleep-mode clients to receive the broadcast. A client receives the schedule, and in order to receive a particular media program at a scheduled time switches to a particular one of the other channels and to wakeup state to receive a particular program.
