Abstract

Embodiments of the disclosure provide a method and apparatus for controlling a startup bootstrap program of an intelligent TV set, and relate to the field of an embedded system so as to shorten a period of time for startup boot while initializing a screen normally. In the disclosure, after a system is powered on, a first task of initializing a screen in a startup bootstrap program is executed, and the length of preset time required for executing the first task is obtained, wherein the startup bootstrap program is a bootstrap program for initializing pieces of software/hardware of the system; executing a second initialization task unrelated to initializing the screen in the startup bootstrap program is executed while the first task is being executed, thus addressing the problem in the related art.

First claim

The invention claimed is:

1. A method for controlling a startup bootstrap program of an intelligent TV set, the method comprising:
upon power-on of the intelligent TV set, executing a first task of initializing a screen of the intelligent TV set in a startup bootstrap program, and determining a length of preset time required for executing the first task, wherein the startup bootstrap program is a bootstrap program for initializing pieces of software/hardware of the intelligent TV set; and
executing a second initialization task which is not associated with operations involved in initializing the screen in the startup bootstrap program while the first task is being executed.

2. The method according to claim 1 , wherein the first task of initializing the screen of the intelligent TV set comprises: a task of initializing a panel, a task of transmitting a panel signal carrying image data of an initialization of the intelligent TV set, a task of initializing an Inter-Integrated Circuit, I 2 C, interface of the screen and a task of initializing a backlight board.

3. The method according to claim 2 , wherein executing the second initialization task which is not associated with operations involved in initializing the screen in the startup bootstrap program while the first task is being executed, comprises:
after executing the task of initializing the panel, executing the task of transmitting the panel signal; and starting a preset timer while starting executing the task of transmitting the panel signal, and executing the second initialization task which is not associated with operations involved in initializing the screen;
after the timer counts to an obtained length of time required for executing the task of transmitting the panel signal, executing the task of initializing the I 2 C interface of the screen and the task of initializing the backlight board sequentially.

4. The method according to claim 2 , wherein executing the second initialization task which is not associated with operations involved in initializing the screen in the startup bootstrap program while the first task is being executed, comprises:
after executing the task of initializing the panel and the task of transmitting the panel signal sequentially, executing the task of initializing the I 2 C interface of the screen; and starting a preset timer while starting executing the task of initializing the I 2 C interface of the screen, and executing the second initialization task which is not associated with operations involved in initializing the screen; and
after the timer counts to an obtained length of time required for executing the task of initializing the I 2 C interface of the screen, executing the task of initializing the backlight board.

5. The method according to claim 2 , wherein executing the second initialization task which is not associated with operations involved in initializing the screen in the startup bootstrap program while the first task is being executed, comprises:
after executing the task of initializing the panel, executing the task of transmitting the panel signal; and starting a preset timer while starting executing the task of transmitting the panel signal, and executing the second initialization task which is not associated with operations involved in initializing the screen;
after the timer counts to an obtained length of time required for executing the task of transmitting the panel signal, executing the task of initializing the I 2 C interface of the screen; restarting the preset timer while starting executing the task of initializing the I 2 C interface of the screen, and executing the second initialization task which is not associated with operations involved in initializing the screen continually if the second initialization task still comprises a task which has not been executed; and
after the timer counts to an obtained length of time required for executing the task of initializing the I 2 C interface of the screen, executing the task of initializing the backlight board.

6. The method according to claim 2 , wherein executing the second initialization task which is not associated with operations involved in initializing the screen in the startup bootstrap program while the first task is being executed, comprises:
after executing the task of initializing the panel, executing the task of transmitting the panel signal; and starting a preset timer while starting executing the task of transmitting the panel signal, and executing the second initialization task which is not associated with operations involved in initializing the screen; and
after the timer counts to an obtained length of time required for executing the task of transmitting the panel signal, executing the task of initializing the backlight board.

7. The method according to claim 1 , wherein a total length of time for executing the second initialization task is no less than a total length of time required for executing the first task.

8. An apparatus for controlling a startup bootstrap program of an intelligent TV set, the apparatus comprising: at least one processor; and a memory, wherein the memory stores therein instructions executable by the at least one processor, and the instructions are executed by the at least one processor to enable the at least one processor:
upon power-on of the intelligent TV set, to execute a first task of initializing a screen of the intelligent TV set in a startup bootstrap program, and to determine a length of preset time required for executing the first task, wherein the startup bootstrap program is a bootstrap program for initializing pieces of software/hardware of the intelligent TV set; and
to execute a second initialization task which is not associated with operations involved in initializing the screen in the startup bootstrap program while the first task is being executed.

9. The apparatus according to claim 8 , wherein the first task of initializing the screen of the intelligent TV set comprises: a task of initializing a panel, a task of transmitting a panel signal carrying image data of an initialization of the intelligent TV set, a task of initializing an Inter-Integrated Circuit, I 2 C, interface of the screen and a task of initializing a backlight board.

10. The apparatus according to claim 9 , wherein the at least one processor is configured:
after executing the task of initializing the panel, to execute the task of transmitting the panel signal; and
to start a preset timer while starting executing the task of transmitting the panel signal, and to execute the second initialization task which is not associated with operations involved in initializing the screen; and
after the timer counts to an obtained length of time required for executing the task of transmitting the panel signal, to execute the task of initializing the I 2 C interface of the screen and the task of initializing the backlight board sequentially.

11. The apparatus according to claim 9 , wherein the at least one processor is configured:
