Abstract
A boot-up method for a digital television device is disclosed which significantly reduces the boot-up time when the power is turned on. At power-on, the control processor first loads a first subset of all the required registers, and start to perform a display function using the first subset of the register values. While the user is viewing the displaying images, the processor loads the remaining registers and completes the boot-up process. The first subset of registers to load may be determined based on information about the last state of the television device before it was last turned off, e.g., what input source a viewer was viewing. Alternatively, it maybe a predetermined subset of registers corresponding to a predetermined initial function.
Claims6
A method for booting up a digital television device, the digital television devices comprising a processor having a plurality of registers, and a memory connected to the processor and storing values for the plurality of registers, the method comprising:
- (a) loading values into a first subset of the plurality of registers from the memory;
- (b) performing a first function of the television device using values of the first subset of registers;
- and
- (c) loading values into a second subset of the plurality of registers from the memory while performing the first function.
