Abstract: A television receives a command to power up from a standby mode. This causes the TV to start a boot process, and while the boot process proceeds. At a point in the boot process when the tuner input switch is operative, the process simultaneously determines a current time from a real time clock and retrieves a channel and a switch setting from a usage pattern database corresponding to the current time. The tuner is tuned to the channel and the input switch is set. At completion of the boot process the tuner is already tuned to the channel and the input switch is set to the switch setting corresponding the current time so that time to viewing a desired channel is often minimized. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

Abstract: The present invention is a television that executes a process for transitioning between multiple power modes. Both the transition events and the power states may be factory-defined, or they may be user-configurable. The TV may have two sleep modes. In a quick-start mode, the screen is powered down but the operating system is spun-up, and possibly other major functional subsystems are user-enabled. In an energy-saving mode, fewer subsystems than quick-start mode, and possibly only components required to recognize a tactile control requesting a return to a power-on mode, may be enabled. Quick-start is less efficient than energy-saving mode, but results in much faster return to power-in mode. In some embodiments, power modes and transition events between them power modes may be automated, and either user defined or factory defined.
