Description

Method for quickly starting computer multimedia playback from standby mode

technical field

The invention relates to a method for starting and executing computer multimedia playing, in particular to a method for quickly starting and executing computer multimedia playing from a standby mode.

Background technique

In computer technology, the traditional method is to install an operating system (Operating System) in the same computer device. When the computer is started, after completing the basic startup procedure of the system, the operating system in the hard disk will be loaded and executed, and the operating system will be loaded. Import and execute device drivers and specified applications.

And as the functions of computers are getting stronger and stronger, and the application fields of computers are also increasing, computer manufacturers just design different computer functions to meet actual needs. For example, a typical application is to combine a computer with a home appliance or a multimedia player to design a multimedia computer system with better functions.

And because different operating systems have their own advantages, so the industry has designed a multimedia computer with dual operating systems. Its general practice is to divide the hard disk into two hard disk partitions, one of which is installed with the first operating system, and the other A second operating system is installed in the partition, the first operating system is responsible for the control of the normal computer operation mode, and the second operating system is responsible for the control of the multimedia playing mode.

In terms of power saving technology, after the computer system completes the boot process, all connected components are driven to work, so the entire computer system will consume rated power. In order to achieve the purpose of saving energy and prolonging the service life of the computer system, the Windows operating system (such as Windows XP, Windows 2000, Windows Me) widely used in the current computer installation has generally integrated the advanced architecture power interface standard ACPI (Advanced Configuration and Power Interface) power management function, with the help of the ACPI interface standard can control the power management operation of related hardware in the computer system.

The Advanced Architecture Power Interface standard, ACPI, manages the power usage of peripheral devices. The power management functions regulated by the ACPI interface standard include functions such as power on (Active), hibernation (Hibernation), standby (Standby), and power off (Shutdown). Under the typical ACPI architecture, the state of the power supply is defined as five different power states, which are:

S0 - normal power supply state.

S1 - first stage standby state, in this state, power to the monitor and disk drives is stopped, but power to the CPU, memory and fans remains.

S2—the second-stage standby state. In this state, in addition to stopping the power supply to the monitor and the disk drive, the power supply to the central processing unit and the cache memory is also stopped.

S3—the third-stage standby state. In this state, the power supply to devices such as monitors, disk drives, CPUs, and caches is stopped, and only the minimum power supply to random access memory (RAM) is maintained.

S4-Sleep state, in this state, the power supply to all devices and components is stopped, but the operating system can store the data and program execution state when the power is turned off before the power is turned off.

S5 - Turn off all power supplies.

According to the user's settings, the computer system can enter the standby or hibernation state. In the standby state, the computer system can be in a low power consumption (Low-power State), and in the hibernation state, the computer system can be in a more power-saving state. .

However, due to the differences in hardware architecture design and functions between computer devices and home appliances or multimedia playback devices, it is difficult to start the computer system in a computer system integrated with home appliances or multimedia playback devices. It can be turned on and off instantly, just like the operation mode of general household appliances or general multimedia playback equipment (such as music CD drive, audio-visual CD drive, etc.).

Although the operators use different operating systems to control the computer operation mode and the multimedia playback mode, when executing the multimedia playback function, the application program of the audio-visual device needs to be activated through the computer system to be executed, and the user must wait for a lengthy boot process. That is to say, the user must start the computer system first, and only after the computer system completes all procedures such as basic input and output system program startup, system self-test, peripheral device detection and drive, operating system startup, and system configuration settings, can the multimedia program be executed. Video playback function. This method does not conform to the habit of common users in operating multimedia playback.

Regardless of the multimedia computer system architecture using a single operating system or dual operating systems, if the user does not want to wait for a lengthy boot process, one of the methods is to turn on the power of the computer first, so that the computer is always on. But this approach will cause the computer to consume unnecessary power.
