ABSTRACT:
A method for transitioning a video system is disclosed. The method generally includes a first step for (A) executing in a processing circuit a standby code stored in a nonvolatile memory while the video system is in an off state, the off state defining a low power configuration for the processing circuit and a power off condition for the video system, the standby code being responsive to a plurality of wake up conditions to wake up the video system. In a second step, the method may (B) store an application code in a volatile memory while in the off state, the application code configured to operate the video system while in an on state of the video system. The method generally includes a third step for (C) transitioning from the off state to the on state upon detection of at least one of the wake up conditions. A step for (D) executing in the processing circuit the application code while in the on state to decode video may also exist in the method.
