Abstract
A system for scheduling caching of in-band data operates as part of a computerized system to receive and store data broadcast in-band in a channel at a scheduled time. The scheduled caching system determines the scheduled time and channel for the in-band data broadcast and causes a real-time clock in the computerized system to schedule a subsequent execution of the scheduled caching system at approximately the scheduled time. When the scheduled caching system subsequently executes, the scheduled caching system instructs tuning circuitry in the computerized-system to tune to the scheduled channel, receives the in-band data from the tuning circuitry and stores the in-band data on mass storage for subsequent processing. The scheduled caching system also powers on the tuning circuitry and parses the in-band data from other content broadcast in the channel if necessary.
