Embodiment Construction

[0011] As shown in FIG. 3, the digital television device has a control processor 31 that controls various functions of the TV. The processor 31 includes a plurality of registers 31a for storing register values ​​which are used by the processor to control the functions of the various sub-components of the digital television device. One reason existing digital TV equipment takes a long time (e.g., 10 seconds or more) to turn on is that when the TV is turned on (powered up), the control processor 31 must be started, and as part of this start-up process, the processor Register 31a is loaded from memory 32 (non-volatile memory or battery backed memory). A modern digital TV has typically a number of registers on the order of 1000, and according to a traditional start-up procedure, all registers are loaded before an image is displayed on the screen.

[0012] However, not all registers are required to perform TV-specific functions. The registers belong to different categories and ar...

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.

Description

technical field [0001] The present invention relates to digital television equipment, in particular to the control of the start-up process of digital television equipment. Background technique [0002] Traditional (analog) TV equipment can be turned on almost instantly, while existing digital TV equipment usually takes a long time to turn on, with a turn-on time of 10 seconds or more. For the convenience of viewers, the turn-on time of digital television equipment needs to be reduced. Contents of the invention [0003] The present invention is directed to circuits and / or firmware for controlling switching on of a digitally controllable SD or HD television device and associated methods, which substantially obviate one or more problems due to limitations or disadvantages of the prior art. [0004] The object of the present invention is to provide a control circuit and / or firmware and method capable of reducing the turn-on time of digital television equipment. [0005] Addi...
