The invention relates to a computer system for accessing multimedia materials and an access method thereof, in particular to a computer system and method for accessing multimedia materials in a non-activated state.

The development of hardware production technology and software services for computer products has been continuously improving. The providers of computer products and services are also focused on providing better and faster equipment and programs to meet the needs of users. . However, the higher the hardware performance of the computer system or the more powerful the application service, the higher the power demand required for its operation. Each time the computer system is started, the power supply source of the computer system needs to be output. Electricity to support the overall operation of the computer system.

But in many cases, users often start a computer system only to perform one or two simple tasks, such as browsing photos and playing videos, but even if only one application service is executed, the computer system is supplied with full operational efficiency and power. Overall operation. In such cases, the power and power consumed by the computer system creates unnecessary waste. Especially users who use portable computer products may often carry their computers outdoors. If you want to share short films with friends at any time, or view photos without power outlets, the battery can be powered for a limited number of hours. Users can't use the portable computer to play multimedia files for a long time with peace of mind. In addition, if the user only wants to perform simple operations such as browsing electronic photos and playing interesting videos, it is still necessary to maintain all the components of the computer system to work, which will undoubtedly cause more power waste. Trouble with this, for electricity Manufacturers and consumers of brain systems have not been effectively addressed.

The computer system for accessing multimedia data in the embodiment of the invention comprises a power supply unit for supplying a computer system, a logic operation module for processing logic operations of the computer system, and a multimedia control module for processing multimedia materials. The operating state of the computer system includes a working state and a non-starting state. When the operating state of the computer system is in a non-starting state, the multimedia control module receives the operating voltage output by the power supply unit, and reads and processes the multimedia data, and then processes the data. The multimedia data is output and played.

The method for accessing the multimedia data by the computer system in the non-activated state according to the embodiment of the present invention includes the following steps: when the operating state of the computer system is a non-starting state, the multimedia control module starts to receive the operating voltage provided by the power supply unit. After obtaining the operating voltage, the multimedia control module begins to accept and process the multimedia data including the image data; and outputs the processed multimedia material for playback.

According to the technical means provided by the present invention, the user can view the photo or watch the movie without starting the computer system, and the power supply of the computer system can be avoided because the power supply is not required to be provided to the device unrelated to the operation of playing the multimedia data. For a more detailed description and implementation, please refer to the following drawings and further description of the embodiments.

The first figure shows a first embodiment of a computer system for accessing multimedia materials provided by the present invention, which includes at least a computer system 10 and a power supply unit 100. The computer system 10 of this embodiment takes a portable computer as an example. Such as a notebook, a smaller mini-notebook (Netbook), or similar handheld electronic devices. The power supply unit 100 can be a battery or AC power source of the portable computer for supplying power required by the entire computer system 10 under various operating conditions. The operational state of computer system 10 includes an operational state and a non-operation state. The non-boot state referred to in this embodiment refers to the sleep state (Hibernation, S4) or shutdown state (Software) defined by the system power state according to the advanced configuration and power interface (ACPI) specifications. Off, S5); The working state refers to the state other than the sleep and shutdown states in the system power state. Since the power supply unit 100 of the computer system 10 does not provide power only when the computer system 10 is in an operating state, unless the power supply unit 100 is completely separated or removed from the computer system 10, when the computer system 10 is in a non-activated state, There are still some system components that are partially operational. For example, in a general computer system, an embedded controller (EC) continues to obtain the standby power of the power supply unit 100 and detects the power supply state of the computer system, but the first embodiment of the present invention The embedded controller is used as the state monitoring unit of the required computer system 10. It should be noted that the state monitoring unit in the first embodiment may be any device in the computer system 10 that can detect the power supply status of the computer system 10. Those skilled in the art can replace the embedded device with other devices according to actual needs. Controller.

The computer system 10 shown in the first figure includes a state monitoring unit 102, a multimedia control module 104, a display screen 106, a data access unit 110, an audio output unit 112, a data switching unit 122, and a logic. The operation module 134 and the power switching units 136 and 138. Logic The computing module 134 is a component of the computer system 10 that processes the logical operations, and includes a central processing unit 116, a logic controller 118, and a system memory 120. In addition, the multimedia control module 104 can be connected to the power supply unit 100 through a voltage voltage stabilizing unit 114. Furthermore, the data switching unit 122 is connected between the logic controller 118, the multimedia control module 104, the data access unit 110, the audio output unit 112, and the display screen 106 including the control panel 108.

As described above, since the state monitoring unit 102 continuously receives the power provided by the power supply unit 100, the state monitoring unit 102 can continuously monitor the condition that the power supply unit 100 provides to the computer system 10, for example, monitors the output of the voltage supply unit 100. The magnitude of the current is used to determine whether to assert the output state switching signal 102_S. Therefore, when the state monitoring unit 102 determines that the computer system 10 is in a non-activated state, for example, when the current value output by the voltage supply unit 100 is lower than a predetermined threshold, the state monitoring unit 102 sets the state switching signal 102_S, and then the power source. The switching unit 138 will be closed according to the indication of the state switching signal 102_S, so that the power supply unit 100 can input the operating voltage required by the multimedia control module 104 therein. In addition, the set state switching signal 102_S also controls the data switching unit 122 to pass the multimedia material to the output end of the data access unit 110 (becoming the output data 110_SO of the data access unit 110), the data switching unit 122, and finally to be regarded as multimedia. The input data 104_SI of the control module 104 is fed to the multimedia control module 104 for further processing. On the other hand, the set state switching signal 102_S also transmits the multimedia data processed by the multimedia control module 104 as the output data 104_SO to the data switching unit 122, and then sent to the display device 106 (video/image/drawing, etc.). The data is played back with the audio output unit 112 (audio data). For the actual implementation, the audio output unit 112 of the embodiment can be further coupled to an earphone output, a speaker, and the like. In addition, the audio output unit 112 can also output a Bluetooth transmission module or a FM transmission module (FM) that transmits audio to the Bluetooth headset. Moreover, when the multimedia data includes both image data and audio data (for example, playing a picture containing background music), in addition to displaying the image screen by the display screen 106, the sound is outputted by the audio output unit 112.

The multimedia control module 104 of the present embodiment can be a codec, such as an MP4 player module, which can read a storage unit (such as a hard disk) built in the computer system 10 or an external storage unit through the data bus (for example) Multimedia file stored on the USB external hard drive). Then, through a processor (such as a digital signal processor (DSP) or a microprocessor) built in the multimedia control module 104 and a converter (such as a DAC) and the like (not shown in the figure) , to compile, interpret or format conversion and other processing procedures. The above multimedia data is audio data, image data, or audio and video data combined with sound and video; image data includes still picture, graphic information, and continuous picture (a The series of pictures constitute an animation or a video; and the multimedia material of the embodiment has at least image data.

The data access unit 110 is, for example, a card reading device on the computer system 10, which can be connected to a storage unit, such as a memory card such as Flash, CF or SD, and reads one or more stored in the storage unit. The multimedia material is transmitted to the multimedia control module 104 for processing. It should be noted that since the multimedia control module 104 is activated when the computer system 10 is in a non-activated state, then the multimedia control module 104 wants to pass the funds. When the material access unit 110 reads a device such as a hard disk or a USB external hard disk of the computer system 10, the multimedia control module 104 must add some drivers or software modules to become a master device to read the slaves. The data in the slave device. For example, the multimedia control module 104 must have an IDE/SATA driver or a software module built in to be an active device to read data on the hard disk. Similarly, the multimedia control module 104 must have a built-in USB driver or The software module can be used as an active device to read multimedia data from a USB external hard drive. Those skilled in the art can increase the driver of the multimedia control module 104 to read the required multimedia materials according to actual needs. Moreover, the control panel 108 of the display screen 106 can include a plurality of operation units (such as a play button and a volume button). The user can control the operation units to generate control commands for controlling the multimedia control module 104 to perform corresponding operations. Multimedia processing

The second figure depicts the internal structure of the data switching unit 122, which includes a multimedia data exchange unit 1222, a video/image/drawing data switching unit 1224, and an audio data switching unit 1226. The multimedia data exchange unit 1222 includes a switching unit 12222 that performs switching according to the indication of the state switching signal 102_S output by the state monitoring unit 102. Since the state switching signal 102_S is set when the computer system 10 is in the non-activated state, it switches the control switching unit 12222 to the Close state, and then the multimedia material 110_SO (taken out by the data access unit 110) becomes multimedia control. The input data 104_SI of the module 104. In addition, the video/image/drawing data switching unit 1224 also includes a switching unit 12242, which is also controlled by the state switching signal 102_S, and switches to the output of the multimedia control module 104 when the computer system 10 is in the non-activated state. To receive the video/image/drawing data 104_SV output by the multimedia control module 104 (for output data) The video/image/drawing data 104_SV is then played back as input data 106_SI transmitted to the display screen 106. Similarly, the audio data switching unit 1226 includes a switching unit 12262, which is also controlled by the command 102_S, and switches to the output of the multimedia control module 104 when the computer system 10 is in the non-activated state to receive the multimedia control module. 104 transmits the audio data 104_SA (also part of the output data 104_SO), and then plays the audio data 104_SA as the input data 112_SI transmitted to the audio output unit 112. It should be noted that, in practical applications, a switch circuit can be provided on a motherboard of a computer system to construct the above-described switching units 12222, 12242, and 12262, so that the manufacturing cost of the entire computer system does not increase too much. And the overall system complexity is not too complicated.

When the computer system 10 is in the active state, the state monitoring unit 102 detects that the current value currently supplied to the computer system 10 is above a predetermined threshold, and the state monitoring unit 102 will de-assert the state switching signal 102_S. Therefore, the switching unit 12242 will switch to the output of the logic controller 118, so that the logic controller 118 can display the display data 118_SV such as video/image/plot as the input data 106_SI of the display screen 106, and then send it to the display screen 106. And output the image screen. On the other hand, the de-asserted state switching signal 102_S also instructs the switching unit 12262 to switch to the output of the logic controller 118, so that the logic controller 118 can use the audio material 118_SA as the input data 112_SI of the audio output unit 112. Then play the game again. In the non-activated state, the display switching unit 122 also switches the connection path because the logic controller 118 does not obtain the power required for the operation, so that the display screen 106 receives the multimedia data processed by the multimedia control module 104 and plays it. It should be noted that this is The multimedia control module 104 of the embodiment uses the original display screen 106 of the computer system 10, so that no additional display screen is required. In addition, the control panel 108 of the display screen 106 includes a plurality of operation units (such as a play button and a volume button), and the user can control the operation unit to generate a control command to control the multimedia control module 104 to execute a corresponding multimedia processing job.

As for the actual implementation of the state switching signal 102_S, one of the general-purpose input and output (GPIO) pins of the embedded controller can be connected to the multimedia control module 104, and a high-potential signal is sent through the general-purpose output pin. The multimedia control module 104 is provided to notify the multimedia control module 104 and initiate subsequent multimedia processing operations. Therefore, the state switching signal 102_S can be switched when the state monitoring unit 102 detects that the computer system 10 is in the startup state (for example, when the current value is higher than a predetermined threshold), and then cancels the setting state switching signal 102_S ( For example, when the state monitoring unit 102 detects that the computer system 10 is in a non-activated state (for example, when the current value is lower than a predetermined threshold), the state switching signal can be The potential value of 102_S is switched to a low potential.

The third figure depicts a power switching state diagram of the first embodiment of the present invention. When the set state switching signal 102_S closes the power switching unit 138 so that the multimedia control module 104 starts to obtain the required operating voltage, the power switching unit 136 is simultaneously turned on, and then the cutoff is provided. The power of the logic operation module 134. In addition, since the data access unit 110, the display screen 106, the audio output unit 112, and the data switching unit 122 in the present invention need to work regardless of whether the computer system 10 is in the activated state or the non-activated state, The power supply unit 100 will continue to provide their required operating voltage without being subject to state switching signals. The status of 102_S (that is, set or not) is affected. It should be noted that the operating voltages of the units of the computer system 10 are not necessarily the same, and the power state diagrams depicted in the third diagram are simplified for convenience of explanation. Those skilled in the art should be aware that in actual implementation, The operating voltage required by the unit is used for circuit layout.

It should be noted that when the computer system 10 enters the working state, the system components (such as the network connection device, the logic operation module 134, etc.) other than the multimedia control module 104 in the computer system 10 are received by the power supply unit 100. electric power. If the user wants to play the multimedia material in the working state, the computer system 10 will use the central processing unit 116 to read the multimedia file stored in the hard disk through the control of the logic controller 118 (such as the south and north bridge chips). After the file conversion or codec processing, it is output to the display screen 106 and/or the audio output unit 112. Obviously, all components except the multimedia control module 104 must enter a working state, that is, the computer system 10 must not be in a non-activated state, so that it is impossible to achieve power saving effects. However, in the embodiment of the present invention, the components that are not used when playing the multimedia material can be turned off (for example, no power is supplied to them), so that the power saving requirement can be achieved.

Since the computer system 10 is in the working state, it is necessary to supply the operating voltage to the various system components, so that the central processing unit 114 performs data processing, hard disk rotation and reading, control of the light number, etc., so as to provide the user through the computer system 10 at any time. For activities such as file editing, Internet access, drawing, or watching movies, power consumption is large under working conditions. In the case of a general notebook computer, the average power supply time of the power supply unit 100 is only about six to eight hours. However, according to the habits of many users, the computer system 10 is often fully activated and consumes a large amount of power, but it is not complicated. The computing operation, but only wants to browse electronic photos, play interesting movies and other simple tasks (for example, as a digital photo frame). At this time, by means of the method provided in this embodiment, a multimedia control module 104 capable of independently processing data can be started in a state where the computer system 10 is turned off or in standby, and only the unit that is indispensable for playing multimedia data is started. Play multimedia files, which not only eliminates the user's expensive program to boot, but also does not need to supply power to other system components that do not work (such as network connection device, logic operation module 134, etc.), so the same power supply The provisioning unit 100 can cause the multimedia control module 104 to operate for a longer period of time.

In the embodiment, the multimedia control module 104 receives the power, and directly connects the multimedia control module 104 to the power supply unit 100, but the voltage voltage stabilization unit 114 can be disposed between the power supply unit 100. The output voltage is reduced to be suitable for use by the operating voltage of the multimedia control module 104; or the standby power source (Standby power) is directly used as the power source, and is sufficient to support the voltage required for the operation of the multimedia control module 104.

In addition, in addition to operating the control panel 108 to input control commands to the multimedia control module 104, the user can also control the output of the display screen 106 by remotely controlling the remote control. Furthermore, the state monitoring unit 102 of the embodiment may include an infrared receiving module 1020. Therefore, the user can send a control command through a remote control device (ie, a remote controller), and the state monitoring is received by the infrared receiving module 1020. The unit 102 then transmits the control command received by the infrared receiving module 1020 to the multimedia control module 104. In the actual implementation, the embedded controller can also be used to achieve the above remote control, because the embedded controller contains consumer infrared (CIR), which is used in the remote control mechanism of the electronic product. . Should pay attention Any module that can be built in the state monitoring unit 102 to respond to the remote control and activate the related operation in the non-activated state can be applied to the embodiment.

The fourth figure is a block diagram of a second embodiment of a computer system for accessing multimedia data provided by the present invention. The second embodiment is different from the first embodiment in that the computer system 10a is further provided with a data access unit 110a directly connected to the multimedia control module 104a, and the multimedia control module 104a is further provided with a storage device. The access interface 1040 does not need to share the original data access unit of the computer system 10a. Specifically, the multimedia control module 104a in the second embodiment is directly connected to the dedicated card reading device (ie, the data access unit 110a), so that the data switching unit 122 does not need to perform data switching, and the device can be stored through the storage device. The interface 1040 directly accesses the data placed by the user into the data access unit 110a, which is relatively easy to manufacture.

In addition, even if the computer system 10a is in the non-activated state, the user does not necessarily want the multimedia control module 104a to perform the processing of processing and outputting the multimedia material. Therefore, the computer system 10a of the second embodiment may include the connection multimedia control mode. The control button 128 of the group 104a, and the user can use the control button 128 to control whether the multimedia control module 104a starts to operate or not.

When the computer system 10a is in the non-activated state, the multimedia control module 104a has obtained the power supplied by the power supply unit 100, but before the user presses the control button 128 to activate the multimedia control module 104a, the multimedia control module 104a The data access unit 110a is not accessed or the multimedia material is processed, and only the standby power supply is used to continuously detect whether the control button 128 is pressed or not (ie, the closed or open state). Until the control button 128 is When the user wants to view the multimedia data processed and output by the multimedia control module 104a on the display screen 106, the multimedia control module 104a starts the operation of processing the multimedia data according to the pressing of the control button 128.

For the connection and function between other components in the second embodiment, please refer to the description of the first embodiment.

The fifth and sixth figures respectively show schematic diagrams of embodiments of a computer system for accessing multimedia data provided by the present invention.

The computer system 10b shown in the fifth figure is a pure tablet tablet (Tablet), which is a type of portable computer. The computer system 10b has a body 132. The display screen 106, the control panel 108, and the audio output unit 112 (such as a speaker) are disposed on the surface of the body 132. The side of the body 132 further includes a data access unit 110 for inserting a memory card (for example, Card reader device). The multimedia control module 104 is disposed in the main body 132. When the computer system 10b is in the non-activated state, the image data may be processed and played according to the requirements of the user according to the first or second embodiment. Multimedia material. As shown in the schematic diagram, after the body 132 of the computer system 10b is placed on a carrier 20 (such as a tripod), the computer system 10b also has the function of a digital photo frame (E-frame) in a non-activated state. It can be used to play multimedia materials such as photos and movies.

The computer system 10c of the sixth figure is a folding tablet computer, and the appearance is similar to a general notebook computer. The body 132a includes a display screen 106 and a keyboard portion. The display screen 106 can be rotated to face the keyboard portion. The function of the carrier 20 in the fifth figure is replaced by the computer system 10c for playing a photo or a movie in a non-activated state.

The seventh figure is a computer system for accessing multimedia provided by the present invention A flowchart of an embodiment of the data method, and please refer to the first figure at the same time. In this embodiment, the state monitoring unit 102 is first used to detect whether the operating state of the computer system 10 is in an active state or a non-activated state (S301). When the computer system 10 is in the non-activated state, the state monitoring unit 102 sets the state switching signal 102_S to notify the multimedia control module 104 to start receiving the operating voltage required for the power supply unit 100 to supply (S303). On the other hand, if the computer system 10 is in the working state, the state monitoring unit 102 will notify the multimedia control module 104 to stop receiving the operating voltage (S315).

After obtaining the voltage required for the operation, the multimedia control module 104 can be started according to the user pressing the control button 128 (refer to the fourth figure) (S305); when the multimedia control module 10 is started, the control panel can be started to be received. 108 or a control command input by the remote control device (S307), for example, browsing multimedia data, playing, stopping playing, etc.; and then performing corresponding processing on the multimedia data according to the received control command (S309), in this embodiment The multimedia data includes at least the image data; the processed multimedia data is output by the multimedia control module 104 to the display screen 106 through the data switching unit 122, and is presented as an image image (S311), and the sound is further output to the audio output unit 112. . In the above process, the state monitoring unit 102 still detects the power state of the computer system 10, and therefore further determines whether the operating state of the computer system 10 has changed (S311). Here, the computer system is judged. 10 has entered the working state. If the operating state of the computer system 10 has not changed, the multimedia control module 104 can return to step S309 and continue to execute the processing of the multimedia data and the output, for example, continuously playing the photo on the display screen 106. However, if it is determined in step S313 that the computer system 10 is in the working state according to the power state change of the computer system 10, then according to the work of the computer system 10 The status performs the following procedure.

After detecting and judging in step S301 or step S313, after the computer system 10 enters the working state, the state monitoring unit 102 cancels the setting state switching signal 102_S to notify the multimedia control module 104 to stop receiving the power supply unit according to the working state. 100 supplied operating voltages (S315); and then power is obtained from the power supply unit 100 by other system components (such as central processing unit 116, logic controller 118, hard disk, etc.) in computer system 10 (S317), thereby The computer system 10 can perform operations and processing through the central processing unit 116 (S319) to provide various service functions provided by the general computer device. At this time, the data switching unit 122 switches the display path of the display screen 106 to connect the display screen 106. At the data output end of the logic controller 118, the data to be displayed is sent to the display screen 106 as an output image screen. As in step S313, the state monitoring unit 102 continues to determine whether the operating state of the computer system 10 changes from the working state to the non-starting state according to the power state of the computer system 10 (S321): if the working state is unchanged, the computer system 10 continues to be The central processing unit 116 and the like provide services (S319); and when the computer system 10 is turned off or in the standby state, the steps S303 and the following are executed again. Thereby, in order to achieve the general operation of the computer system 10 in the working state, the effect of accessing the multimedia material and displaying it can be provided in the non-activated state.

Therefore, combining the above-described illustrated contents and drawings, it can be seen that the computer system and the method for accessing multimedia data provided by the present invention can be used in cooperation with the original system device of the computer system. Taking the example illustrated in the above embodiment as an example, the embedded controller only needs to use a general-purpose output input pin to implement the transmission of the switching signal, and the card reading device can read the memory card. Picture or video files, display screens and audio output units are essential components in general computer systems; computer system producers do not need to adjust the computer system architecture to avoid the increase in cost in order to provide multimedia services when they are not turned on.

In addition, after the power is turned off, the original power supply unit is used for power supply. Even if the multimedia data control mechanism is provided, there is no need to separately configure an external power supply or a backup power supply plus the original power supply unit of the computer system to avoid the manufacturing cost of the computer system. Or the device volume increases. In the non-activated state, the power supply unit only needs to provide the power needed to process and play multimedia data. It saves a lot of power compared to the traditional way of making the entire computer system fully operational, and the playback time can be extended.

In addition, the method of providing multimedia data control in the non-activated state is also in line with the user's preference to watch pictures or audio and video for a long time, combining the advantages of low production cost and power saving; taking portable computers as an example, using The computer system that can access the multimedia can also access the multimedia file at any time outdoors, thereby increasing the convenience of use and improving the use value of the computer system.

However, the items and elements of the above-described embodiments are merely illustrative of the invention and are not intended to limit the scope of the claimed invention. It is also within the scope of the present invention to modify or modify the micro-frames in accordance with the spirit of the present invention and the technical means disclosed herein.
