Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computer system, and more particularly to a computer that can process a multimedia file without being turned on. [Prior Art] In the prior art, the playback of multimedia files such as video, music, etc. by a user through a computer has become a fairly common application. However, when a user wants to play a multimedia file through a computer, it is often necessary to turn on the main power of the computer to start the computer's operating system. After that, the user still needs to execute a program suitable for the multimedia file he wants to play, so as to play more and more files. The above boot process, in the average personal computer fee for one to two minutes. In addition, after entering the operation surface of the operating system, the data stored in different bits according to different applications and peripheral devices = the player must repeatedly operate the mouse button to complete the operation of the multimedia broadcast operation. The time will vary depending on when the user is looking for multimedia. The above-mentioned booting procedure and operation process, ^ λ said that there is a considerable degree of inconvenience, so that the user's intention to play the multimedia application is lowered, causing the computer resources to be insufficiently profitable. The main scope of the present invention is to provide a computer system to solve the above problem. Under the condition of the present invention, the invention provides a computer system capable of processing a multimedia file (Main_p_r_). Referring to 5 1297452, the user makes a wish for the (4) physical touch application, thereby making the computer resources fully utilized. According to a preferred embodiment, the computer system of the present invention includes a backup power supply ( Standby power supply), a storage device (St〇rage (10)(3)), a control (C=tr〇ller), a decoder (Dec〇der), and at least—output unit (〇帅 says unit). Standby power supply It is used to provide a backup power supply. The storage device is used to store the multi-ship county, and in the unpowered state τ, the power supply provides a backup power dump device. Control||Response-request (4) coffee, call The multimedia file is accessed from the cache device, and in the unpowered state, the backup power supply provides backup power to the controller. The decoder responds to the request signal for use in the system. Receiving a multimedia file, and interpreting the multimedia file into a plurality of output signals, and in an unpowered state, the standby power supply provides a backup power supply to the decoder. At least one output unit responds to the request signal for receiving and outputting the same. The output signal is provided, and in the unpowered state, the backup power supply provides backup power to the transmission unit. In this way, with the computer system of the present invention, the backup power supply provides backup power to the playback state in the unpowered state. The related devices required for the multimedia file enable the corpse user to play the multimedia 梓^ without turning on the main power of the computer system, thereby improving the convenience and efficiency of playing the multimedia file. Since it is not necessary to start the entire computer system, the multimedia file can be played, and the energy required for the same application is also reduced. The advantages and spirit of the present invention can be further understood by the following detailed description of the invention. [Embodiment] Please refer to FIG. 1. FIG. 1 is a schematic diagram of a system 10 according to a first preferred embodiment of the present invention. The function of the ab block. The computer system (C〇mputer SyStem) can be used in the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The multimedia file can be an audio file (Audi〇flle) or a video file. As shown in Figure 1, the computer system 1 includes a main power supply 12 and a standby power supply (standby p〇). Wer suPPly)14, power selector (power seiect〇r) i6, data selector 18, storage device 20, controller 22, mainboard controller (Motherboard controller) 24 A decoder (Dec) 26, an output unit 28, and a console 30. The storage device 20 is used to store multimedia files. In this embodiment, the data selectors 18, 22, the motherboard controller 24, and the storage device 2G may be: SCSI, USB, IEEE 1394, etc. Switch to the motherboard controller 24, which provides the data to the motherboard controller

In the first preferred embodiment described above, when the main power source 12 of the computer system 10 is in the on state, the power selector 16 selects the main power supply 12 as a source of power supply, and the data selector 18 will path

The computer system 14 serves as a power supply. The data selector 18, i.e., the power supply 14, provides backup power to the data selection, controller 22, decoder 26, and output unit 28. At this time, the company will transfer the poor material route to the library storage 1 20, and store the storage 2 (^, supply controller 22. Then, the controller will set two 20 will be set to 20 access use The specified multimedia slot case. After the code is stored, the request signal is received from the controller 22, and the horse state 26 returns f to the plurality of output signals. The output unit 28 includes the solution to the ^utput control device. ) 280 ^(Output devi^gl ΪΪ = and play the playback signal, and then complete the multimedia slot case, because the backup power supply will provide backup power to the device: the relevant device required for the media file, therefore, use , the main power of the eve of the night, riding the multimedia _ case _ put. Ή computer system ^ (Speaker), ^ format, and the output control device is the audio codec please refer to the second 'Figure 2 is according to the present invention The functional block diagram of the computer system 50 of the second preferred embodiment. The main difference between the computer system 5 and the computer system 1 is that the output unit 28 of the power system 50 additionally includes a wire transmission kdess transmitter. Shown. Wireless transmitter 284 is used The line receives and transmits the interpreted output signal to the remote_distribution device (not shown) for multimedia viewing. For example, when the user wants to play the audio file away from the computer system (if the help When the signal is transmitted to the speaker of the user's location by the wireless transmitter m, the audio file can be played. Thus, the user can fully utilize the computer resources without the constraints of the space. The other functional principle of the system 5G is the same as that of the computer system 1() in the figure--, and will not be described here. 8 1297452 Power supply: The field computer system is not powered on, and the backup power supply is required for playing multimedia files. Device, "No" • When the main power of the computer system is turned on, the multimedia ί 3 i will improve the convenience and effectiveness of playing the multimedia file. The energy required to broadcast the same application will also be reduced. What's more, Wireless Jay's configuration allows users to be free from space constraints. The detailed description of the preferred embodiments is intended to provide a clear description of the features and spirit of the present invention, and is not intended to limit the scope of the present invention. The various modifications and equivalent arrangements are intended to be within the scope of the claimed invention. 1297452 [FIG. 1] FIG. 1 is a functional block diagram of a computer system in accordance with a first preferred embodiment of the present invention. 2 is a functional block diagram of a computer system in accordance with a second preferred embodiment of the present invention.
