Since the above remote control methods are executed only in the operating system, the above remote control methods are only allowed to execute In-Band control, and the access authorities thereof are strict restricted by the operating system. This is inconvenient to users. For example, the display screen of the local computer may not be obtained when the local computer is shut down, or the operating system is not loaded.

The present invention may retrieve the video signal directly from the processor to prevent the strict restrictions of access authorities from the operating system, and the out-of-band remote mirror display is implemented.

The features of the present invention are believed to be novel are set forth with particularity in the appended claims. The present invention itself, however, may be best understood by reference to the following detailed description of the present invention which describes an exemplary embodiment of the present invention, taken in conjunction with the accompanying drawings, in which:.

The technical contents of this invention will become apparent with the detailed description of embodiments accompanied with the illustration of related drawings as follows. It is intended that the embodiments and drawings disclosed herein are to be considered illustrative rather than restrictive.

Please refer to <FIG> illustrates an architecture diagram of the remote monitoring system. In the remote monitoring system, a Baseboard Management Controller (BMC) <NUM> is arranged in a local computer <NUM>.

The BMC <NUM> is connected to the network module <NUM>, and is used to implement the Out-Of-Band management of the local computer <NUM>. For example, a remote computer <NUM> may control the local computer <NUM> to be booted, shut down, or obtain status information of peripheral device <NUM> or chipset <NUM> through the network <NUM> and the BMC <NUM>. The remote computer <NUM> may further control the peripheral device <NUM> or the chipset <NUM> of the local computer <NUM> through the network <NUM> and the BMC <NUM>.

However, under the architecture of this remote monitoring system, due to the restrictions of access authorities, the BMC <NUM> is unable to directly receive the video signal (namely, the display screens of the local display <NUM>) generated by the processor, and is unable to implement the remote mirror display. Namely, the BMC <NUM> does not have the ability to provide the display screens of the local display <NUM> to the remote computer <NUM> for mirror display. Besides, the BMC <NUM> may be further connected to another local display <NUM>, and display the related information on the local display <NUM>.

Please refer to <FIG> illustrates an architecture diagram of another remote control system. The remote control system uses the Intel Active Management Technology (AMT) provided by Intel® to implement the remote mirror display.

More specifically, inside the local computer <NUM>, AMT <NUM> is deployed inside the processor <NUM>, and the AMT <NUM> is deployed inside the chipset <NUM>. AMT <NUM> of the processor <NUM> has the ability to transmit the display screens (video signal) to the local display <NUM> for displaying. Besides, AMT <NUM> has the ability to transmit the same display screens to the AMT <NUM> of the chipset <NUM>, and transmit the display screens to the remote computer <NUM> through the chipset <NUM> (connected to the above-mentioned network module <NUM>) and network <NUM>, so as to display the mirror display screens of the local display <NUM> on the remote display <NUM> and achieve the remote mirror display.

However, the AMT function is deployed only inside the Intel® high-level processor, and must collocate with designated Intel® chips, such that the cost of remote mirror display is high. Namely, the disadvantages of the AMT function are significantly increasing hardware costs and significantly reducing the deployment flexibility of hardware. Moreover, the above-mentioned AMT <NUM> and AMT <NUM> are like a black box that no internal architecture is allowed to be inspected. The general deployers are unable to know the specific structure of AMT, and unable to modify or customize the AMT.

To solve the above-mentioned problems, the present invention discloses a computer system, a remote control monitoring system, and a remote control monitoring method with remote control monitoring function, the computer system, the remote control monitoring system, and the remote control monitoring method may achieve the Out-Of-Band management and remote mirror display. A detailed explaining is below.

Please refer to <FIG> illustrates an architecture diagram of the computer system of one embodiment of the present invention. The computer system (hereinafter as local computer <NUM>) with remote control monitoring function of the present invention, such as desktop computer, laptop, workstation, server, etc., mainly includes a processor <NUM>, a chipset <NUM>, a network module <NUM>, a local display <NUM>, and a remote control monitoring system <NUM>.

The processor <NUM>, such as CPU (Central Processing Unit), is used to execute the main computation (or calculation) and control. The chipset <NUM> is electrically connected to the processor <NUM> and the other devices, such as the network module <NUM> or the peripheral devices <NUM> recited below, and used to be controlled by the processor <NUM> to drive the other devices. The network module <NUM>, such as Ethernet card, Wi-Fi network card, cellular network module, or the other network modules with networking capability, is used to connect to the network <NUM> (such as the Internet), and communicate with the remote computer <NUM> through the network <NUM>. The local display <NUM>, such as touchscreen, LCD screen, projector, plasma screen or the other types of displays, is used to display information.

The remote control monitoring system <NUM> is mainly used to instantly (in real-time) provide the local display screens (namely, the display screen of the local display <NUM>) of the local computer <NUM> to the remote computer <NUM>, such as the desktop computer, laptop, workstation, server, etc., for remote real-time display.

More specifically, the remote control monitoring system <NUM> includes a signal receiver <NUM> and a remote controller <NUM>. The signal receiver <NUM> may be obtained by modifying the display adapter. The signal receiver <NUM> is directly connected to the processor <NUM>, and is able to receive the video signal corresponding to the local display screens from the processor <NUM>. The remote controller <NUM> may be obtained by modifying the BMC or the single-chip controller. The remote controller <NUM> is used to transmit the received video signal to the remote computer <NUM> to achieve the remote mirror display.

More specifically, please also refer to <FIG> illustrates a flowchart of the remote control monitoring method of one embodiment of the present invention.

In this exemplary embodiment, when the local computer <NUM> is operated (such as booting is done), the processor <NUM> continuously transmits the video signal V1 to the local display <NUM> to display the local display screens on the local display <NUM>.

Moreover, when the remote mirror display is started, the step S10 is executed, the processor <NUM> provides the video signal compatible with a first standard (namely, the first video signal S1, such as DisplayPort standard or the other output standard supported by processor <NUM>), and the signal receiver <NUM> continuously receives the first video signal S1 from the processor <NUM>.

Then, the step S11 is executed, since the remote controller <NUM> is usually configured to be unable to access the output standard (first standard) of the processor <NUM>, in the present invention, the signal receiver <NUM> is configured to execute a signal transforming process (such as the video standard transformation) on the first video signal S1 to convert the first standard of the first video signal S1 into the input standard (the second standard, such as HDMI standard, VGA standard, DVI standard, TTL standard, LVDS standard, CVBS standard, S-Video standard, YPbPr standard, etc.) supported by the remote controller <NUM>. Thus, the second video signal S2 in a different standard from the first standard can be obtained.

Then, the step S12 is executed, the signal receiver <NUM> transmits the second video signal S2 to the remote controller <NUM>.

Next, the step S13 is executed, since the general video standards are unable to be transmitted through the network, in the present invention, the remote controller <NUM> executes a network compressing process (such as the streaming transformation) on the second video signal S2 to generate the video data S3 compatible to a network-transportable standard, such as Real Time Streaming Protocol (RTSP).

Next, the step S14 is executed, the remote controller <NUM> transmits the generated video data S3 to the network module <NUM>, the network module <NUM> transforms the video data S3 into the network-transportable video data S4, such as data packets, and transmits the video data S4 through the network <NUM> to the remote computer <NUM>. The remote computer <NUM> may execute a decoding process which may include the decapsulation, the video standard conversion, etc., on the received video data S4 to obtain the video signal V2, and transmit the video signal V2 to the remote display <NUM>. Thus, the remote display <NUM> is able to display the remote display screens corresponding to the local display screens.

In one of the exemplary embodiments, the remote display screens are the mirror screens of the local display screens. In other words, the remote display screens have the same framework, typesetting, and displayed content as the local display screens, but the remote display screens shown on the remote display <NUM> may be configured to different display parameters, such as resolution or aspect ratio, from the local display screens shown on the local display <NUM>.

In one of the exemplary embodiments, a part of each remote display screen may render a display window, this display window is used to show each received local display screen, and another part (display zones) of each remote display screen may be still used to perform the operation to the remote computer <NUM> or display the information of the remote computer <NUM>.

The present invention is able to obtain the video signal directly from the processor <NUM> to prevent the strict restrictions of access authorities from the operating system, and the out-of-band remote mirror display may be implemented. For example, when the present invention is used, the out-of-band remote mirror display, such as the BIOS configuration screen, operating system selection screen, etc., may be achieved.

Please refer to <FIG> illustrates an architecture diagram of the video components of one embodiment of the present invention. <FIG> is used to exemplarily explain how the signal receiver <NUM> of the present invention receives the above-mentioned first video signal S1 directly from the processor <NUM>.

In this example, the processor <NUM> includes a DDI <NUM>, the DDI <NUM> is a module to implement the Data Direct Input (DDI) technology. A main purpose of DDI is to make the processor <NUM> be able to output the video signal directly to the other device (<FIG> uses the display adapters <NUM>-<NUM> and the signal receiver <NUM> for example) without transmitting through the main memory (such as RAM), so as to achieve high-speed signal transmission.

In this example, the processor <NUM> includes four video signal ports <NUM>-<NUM>, each of the video signal ports <NUM>-<NUM> is configured to output the video signal compatible with the above-mentioned first standard. For example, the video signal ports may be the signal output ports of DisplayPort, and the number of the video signal ports may be modified arbitrarily.

The video signal ports <NUM>-<NUM> are respectively connected to the display adapters <NUM>-<NUM>, each display adapter <NUM>-<NUM> are respectively connected to the corresponding display connectors <NUM>-<NUM>. Each display adapter <NUM>-<NUM> is used to transform the video signal of the first standard into the video standard supported by the connected display connector <NUM>-<NUM>.

For example, the display adapter <NUM> is configured to transform the video signal from the DisplayPort standard into the HDMI standard, and transmit the HDMI video signal to the display connector <NUM>, such as HDMI connector. Then, the display connector <NUM> transmits the HDMI video signal to the local display <NUM> for displaying.

In the present invention, one video signal port <NUM> of the processor <NUM> is modified to be connected to the signal receiver <NUM>, and the video signal ports <NUM> and <NUM> are configured to a mirror display mode. Namely, the video signal outputted by the video signal port <NUM> is the same as the video signal outputted by the video signal port <NUM>. Thus, the signal receiver <NUM> may directly receive the mirror video signal through the DDI <NUM> from the processor <NUM>, execute the signal standard transformation, and provide the transformed video signal through the remote controller <NUM> and network <NUM> to the remote computer <NUM> for displaying.

Please refer to <FIG> illustrates an architecture diagram of the video components of one embodiment of the present invention. In the example shown in <FIG>, the remote control monitoring system may include a high-speed hub <NUM>. The high-speed hub <NUM> may include one or more input interfaces and multiple output interfaces.

When the display connector <NUM> and the remote controller <NUM> are compatible with the same video standard (such as HDMI standard or VGA standard), the present invention may directly connect single channel (the signal video signal port <NUM>) separately into multiple channels (the local display <NUM> and the remote controller <NUM>), so as to omit the configuration related to the above-mentioned mirror display mode.

More specifically, in the present invention, the video signal port <NUM> is connected to the signal receiver <NUM>, one input interface of the high-speed hub <NUM> is connected to the signal receiver <NUM>, and two output interfaces of the high-speed hub <NUM> are respectively connected to the display connector <NUM> (connected to the local display <NUM>) and the remote controller <NUM>. Thus, the first video signal in the first standard provided by the processor <NUM> is inputted to the signal receiver <NUM> through the video signal port <NUM>, the signal receiver <NUM> transforms the first video signal in the first standard into the second video signal in the second standard (such as HDMI standard or VGA standard). Then the second video signal is inputted to the high-speed hub <NUM>, and broadcasted to the display connector <NUM> and the remote controller <NUM>. Thus, the local display <NUM> is able to show the local display screens, and the remote display <NUM> is able to show the mirror remote display screens.

Please refer to <FIG> and <FIG> simultaneously, <FIG> illustrates an architecture diagram of the computer system of one embodiment of the present invention, and <FIG> illustrates an architecture diagram and a flowchart of the remote control monitoring method of one embodiment of the present invention.

In this example, the local computer <NUM> may include one or more peripheral devices <NUM>, such as a cooling fan device, power supply, hard disk, keyboard, mouse, etc. Each peripheral device <NUM> is connected to the chipset <NUM> for being locally monitored and controlled. Each peripheral device <NUM> may be further connected to the remote controller <NUM> (not shown in the figures) for being remotely monitored and controlled. The remote controller <NUM> is connected to the chipset <NUM> and the processor <NUM>.

The remote control monitoring may include the Basic Input/Output System (BIOS) <NUM>. The BIOS <NUM> is installed in the local computer <NUM> (such as being installed in the EEPROM). The BIOS <NUM> is loaded and executed after the local computer <NUM> is booted, so as to execute the hardware initialization of the local computer <NUM>.

In one of the exemplary embodiments, when the local computer <NUM> loads and executes the BIOS <NUM>, the BIOS <NUM> may set the first video signal port (such as the video signal port <NUM> as shown in <FIG>) and the second video signal port (such as the video signal port <NUM> as shown in <FIG>) connected to the processor <NUM> to be a mirror display mode to make the two video signal ports be configured to transmit the same first video signal.

The execution flow of the remote control monitoring method of this embodiment is below.

In the step S200, the processor <NUM> continuously transmits the video signal of the local display screens to the local display <NUM> for displaying after being booted.

When the remote mirror display is executed, the step S201 is executed, the remote user may operate the input device <NUM> of the remote computer <NUM> to send a remote switch request through the network <NUM> to the remote controller <NUM>. The above-mentioned remote switch request may include the login data, such as any combination of the account name, password, IP address of remote computer <NUM>, MAC address of remote computer <NUM>, and the other verifiable information.

In the step S202, the remote controller <NUM> may execute an authentication on the login data of the remote switch request after the remote switch request is received. For example, the remote controller <NUM> may determine whether the login data is consistent with the predefined registration data.

In one of the exemplary embodiments, the remote computer <NUM> may further send an operation command or a check request of the peripheral device <NUM> to the remote controller <NUM>, the remote controller <NUM> may execute the corresponding control (such as direct controlling or controlling through the chipset <NUM>) based on these requests. For example, the remote controller <NUM> may control the peripheral device <NUM> based on the operation command, or return the status information of the peripheral device <NUM> as the step S210.

For example, the operation command may be the mouse input operation and/or the keyboard input operation from the remote end to the local end. The remote computer <NUM> may control the local end to trigger the corresponding mouse event and/or the corresponding keyboard event based on the control request.

In the step S203, the remote controller <NUM> transmits an enabling display notification to the signal receiver <NUM> after the remote switch request is verified.

In the step S204, the signal receiver <NUM> may be connected to the chipset <NUM>, such as the pins of General-purpose input/output (GPIO), and transmit the enabling display notification to the chipset <NUM>.

In the step S205, the chipset <NUM> notifies the processor <NUM> to enable the video signal port (such as the video signal port <NUM> shown in <FIG>) connected to the signal receiver <NUM>.

In the step S206, the processor <NUM> starts to transmit the first video signal corresponding to the local display screens to the signal receiver <NUM>.

In the step S207, the signal receiver <NUM> transforms the first video signal into the second video signal supported by the remote controller <NUM>.

In the step S208, the signal receiver <NUM> inputs the second video signal to the remote controller <NUM>.

In the step S209, the remote controller <NUM> transforms the second video signal into the network-transportable video data.

In one of the exemplary embodiments, step S210, the remote controller <NUM> may obtain the status information of the components, such as the peripheral device <NUM>, the network module <NUM>, the devices connected to the chipset <NUM>, etc., of the local computer <NUM> by the chipset <NUM> or direct connection, and transmit the obtained status information to the remote computer <NUM>.

In the step S211, the remote controller <NUM> transmits the video data through the network module <NUM> to the remote computer <NUM>, the remote computer <NUM> processes the video data and starts to display the remote display screens mirroring the local display screens on the remote display <NUM>.

Thus, the present invention may make the remote display <NUM> be switched to display the local display screens, make the remote input devices <NUM> be able to control the local computer <NUM>, and achieve the remote KVM switch function.

Please be noted that the present invention may further provide a display screen refresh function and a disconnection control function during the execution of remote mirror display.

More specifically, please refer to <FIG> illustrates a partial flowchart of the remote control monitoring method of one embodiment of the present invention.

In the step S30, during executing the remote mirror display, at least one of the signal receiver <NUM>, the remote controller <NUM>, and the processor <NUM> continuously detects whether a preset refresh condition is met. The refresh condition may include the local display screen being changed or a preset time interval (such as <NUM>/<NUM> seconds) being elapsed.

In the step S31, the signal receiver <NUM> (and the remote controller <NUM>) executes the above-mentioned steps S10-S14 (or the steps S206-S211) again to obtain the new (current) first video signal the new (current) local display screens from the processor <NUM>, executes the signal transforming process on the new first video signal to generate the new second video signal, executes the network compressing process on the new second video signal to generate the new video data, and transmits the new video data through the network module <NUM> to the remote computer <NUM>. Then, the remote display <NUM> refreshes its screen to display the new remote display screens corresponding to new local display screens.

Thus, the present invention may achieve the display screen refresh function of remote display screen.

In the step S32, at least one of the signal receiver <NUM> and the remote controller <NUM> detects whether the remote control is terminated (discontinued), such as the remote user disconnects the connection, or connection timed out, etc..

In the step S32, when termination of the remote control is detected, the remote controller <NUM> sends a disabling display notification through the signal receiver <NUM> to the chipset <NUM>, and the chipset <NUM> notifies the processor <NUM> to stop providing the first video signal to the signal receiver <NUM> to stop providing the mirror display screens.

Please be noted that, when the remote mirror display is started, the processor <NUM> may configure the video signal port <NUM> (as shown in <FIG>) connected to the signal receiver <NUM> to be "display connected". In other words, the local user may watch through the local computer <NUM> that the local computer is connected to two displays simultaneously, one is the local display <NUM>, another is the remote display <NUM>.

If the connection between the remote controller <NUM> and the remote computer <NUM> is disconnected without changing the above configuration of the video signal port <NUM>, the local user continuously sees that the local computer <NUM> is connected to two displays even if the remote control is terminated. This situation may cause confusion to the local user.

In this regard, the present invention notifies the processor <NUM> to stop proving the video signal to the signal receiver <NUM> through the chipset <NUM> when the remote control is terminated. The above feature enables the processor <NUM> to automatically configure the video signal port <NUM> (as shown in <FIG>) connected to the signal receiver <NUM> to be "display removed" after the termination of the remote mirror display. The local user may see that the local computer <NUM> is connected to only one display (local display <NUM>), and the confusion to the local user is avoided. The present invention can improve the user experience.

Please refer to <FIG> illustrates an architecture diagram of the signal receiver of one embodiment of the present invention. In this exemplary embodiment, the signal receiver <NUM> may include a signal input module <NUM>, a signal output module <NUM>, a memory <NUM>, and a signal processing module <NUM> electronically connected to the above components.

The signal input module <NUM>, such as DisplayPort signal input, is used to receive the first video signal. The signal output module <NUM>, such as TTL <NUM> bits signal output, is used to output the transformed second video signal. The memory <NUM>, such as flash memory or cache memory, is used to store data. The signal processing module <NUM> is used to execute the above-mentioned signal transforming process.

In one of the exemplary embodiments, the signal processing module <NUM> is connected to a set of pins <NUM>, such as GPIO pins, of the chipset <NUM>, and executes the signal transmission with a hot plugging controller <NUM> of the processor <NUM>. By the above architecture, the signal processing module <NUM> may control the processor <NUM> to change the status of the video signal port <NUM> (shown in <FIG>), such as configuring the video signal port <NUM> to be "display connected" or "display removed". The signal processing module <NUM> may control the processor <NUM> to start to provide the first video signal and/or stop providing the first video signal.

Please refer to <FIG> illustrates an architecture diagram of the remote controller of one embodiment of the present invention. In this exemplary embodiment, the remote controller <NUM> may include a signal input module <NUM>, a network processing module <NUM>, a connection module <NUM>, a storage module <NUM>, and a control module <NUM> electrically connected to the above components.

The signal input module <NUM>, such as TTL <NUM> bits signal output, is used to receive the second video signal. The network processing module <NUM> is used to execute the above-mentioned network compressing process. The storage module <NUM>, such as flash memory or cache memory, is used to store data. The control module <NUM> is used to execute the above-mentioned remote monitoring and control function.

In one of the exemplary embodiments, the remote controller <NUM> may be obtained by modifying the BMC, such as AST2400, AST2500, AST <NUM> of ASPEED® or the other System on Chip (SoC). More specifically, the BMC may include signal output module (such as TTL 24bits signal output), the present invention may modify this signal output module to connect to the signal receiver <NUM> as the signal input module.

The present invention may be implemented by modifying the existing chips, thereby the present invention may significantly save the cost to developed and produce the new functional chips.
