Description

  The present invention relates to an information processing apparatus such as a personal computer and an error detection method applied to the apparatus.

  In recent years, personal computers having the same AV function as audio / video (AV) devices such as DVD (Digital Versatile Disc) players and TV devices have been developed.

  In such a personal computer, an application program (AV application program) for executing the AV function is installed. This AV application program is usually configured to operate in cooperation with various other programs such as a service program and a driver program in order to efficiently execute various processes.

  A personal computer capable of performing scheduled recording of broadcast program data is also provided with a function for automatically executing an application program for executing recording processing slightly before the recording start time of the broadcast program data arrives. ing.

A communication terminal device having the function is disclosed.
JP 2002-190847 A

  By the way, in the personal computer, not only application programs but also many other service programs, driver programs, and the like are executed. These programs are automatically started sequentially by the operating system when the personal computer is started. For this reason, there are service programs and driver programs that are not in an execution state immediately after the personal computer is started, and in an execution state after a while.

  Therefore, it may be assumed that a service program that can be used without any problem when the personal computer is in a normal operating state cannot be used immediately after the personal computer is started.

  Normally, an application program that operates in cooperation with a service program waits for the service program to start executing for a certain timeout period. If the service program does not enter the execution state even after the timeout period elapses, the application program It is determined that the application program is not in an environment where normal operation is possible, and occurrence of a timeout error is detected.

  Therefore, if the application program is started immediately after the personal computer is started up, a situation may occur in which the service program will be treated as a timeout error even if it waits for a while, even though the service program enters the running state. is there.

  In addition, the application program for executing the recording process is not only activated by a user operation, but may be automatically activated according to the recording start time of the broadcast program reserved for recording. At the time of automatic startup, the personal computer is started slightly before the recording start time, and immediately after that, the application program is started. For this reason, the above-described timeout error is likely to occur due to the application program being started during the execution preparation period of the program to be operated in cooperation.

  The present invention has been made in consideration of the above-described circumstances, and can efficiently prevent the occurrence of a timeout error due to the application program being started during the execution preparation period of a program to be operated in cooperation. An object is to provide a possible information processing apparatus and an error detection method.

  In order to solve the above-described problem, an information processing apparatus according to the present invention includes a detection unit that detects an elapsed time since the operating system was last started when a predetermined application program is started, and the detected progress When the time exceeds the predetermined time, the first time-out time is selected, and when the detected elapsed time is within the predetermined time, the second time-out time longer than the first time-out time is selected. Executing a state check process for checking a state of a predetermined program to be operated in cooperation with the predetermined application program, and starting the state check process, and then selecting the selected The predetermined program is executed during the period until the first or second timeout time elapses If it is state is not confirmed, characterized by comprising an error output means for outputting a message indicating the occurrence of an error.

  According to the present invention, it is possible to efficiently prevent the occurrence of a time-out error due to the application program being started during the execution preparation period of a program that should operate in cooperation.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
First, with reference to FIG. 1 and FIG. 2, the structure of the information processing apparatus which concerns on one Embodiment of this invention is demonstrated. This information processing apparatus is realized by, for example, a notebook portable personal computer 10.

  The computer 10 has a TV function for executing reproduction and recording of broadcast program data broadcast by a broadcast signal. This TV function also includes a reserved recording function for recording broadcast program data in accordance with a recording reservation set by the user. The computer 10 has an AV data library function for managing and reproducing AV contents such as video and audio stored in a storage medium such as a DVD medium or a hard disk. For example, it is realized by an AV application program installed in the computer 10 in advance.

  FIG. 1 is a perspective view of the computer 10 with the display unit opened. The computer 10 includes a computer main body 11 and a display unit 12.

  The display unit 12 incorporates a display device including a TFT-LCD (Thin Film Transistor Liquid Crystal Display) 17. The display unit 12 is attached to the computer main body 11 so as to be rotatable between an open position and a closed position.

  The computer main body 11 has a thin box-shaped casing, and a keyboard 13, a power button 14 for turning on / off the computer 10, an input operation panel 15, a touch pad 16, and the like are arranged on the upper surface thereof. Has been.

  In addition, a remote control unit interface unit 20 for executing communication with an external remote control unit for remotely controlling the TV function of the computer 10 is provided on the front surface of the computer main body 11. The remote control unit interface unit 20 includes, for example, an infrared signal receiving unit.

  Next, the system configuration of the computer 10 will be described with reference to FIG.

  As shown in FIG. 2, the computer 10 includes a CPU 111, a north bridge 112, a main memory 113, a graphics controller 114, a south bridge 119, a BIOS-ROM 120, a hard disk drive (HDD) 121, and an optical disk drive (ODD) 122. , Tuner devices (receiving devices) 123A and 123B, an embedded controller / keyboard controller IC (EC / KBC) 124, a network controller 125, and the like.

  The CPU 111 is a processor provided to control the operation of the computer 10, and stores various application programs such as the operating system 102 and the AV application program 101 that are loaded from the hard disk drive (HDD) 121 to the main memory 113. Execute. The CPU 111 also executes various service programs, device driver programs, database service programs, and the like. These service program, device driver program, database service program, and the like are automatically activated by the operating system 102 when the operating system 102 is activated.

  The AV application program 101 executes a TV function for controlling reproduction and recording of broadcast program data, an AV data library function for managing and reproducing AV contents such as video and audio stored in a storage medium, and the like. It is an application program.

  At the time of executing the TV function, the AV application program 101 controls the tuner devices 123A and 123B to execute reproduction and recording (including reservation recording) of broadcast program data (TV broadcast program) broadcast by the broadcast signal. To do. The AV application program 101 is configured to operate on the operating system 102. The AV application program 101 is configured to operate in cooperation with various service programs, SQL database service programs, and the like, and further uses various device driver programs. For this reason, in order for the AV application program 101 to operate normally, it is necessary that the above-mentioned various programs to be linked with the AV application program 101 are in an execution state.

  Various programs to be linked with the AV application program 101 are registered in advance in the operating system 102. This registration processing is executed, for example, by the installer of the AV application program 101 when the AV application program 101 is installed. When the operating system 102 is activated, the operating system 102 sequentially activates various programs (service program, device driver program, SQL database service program, etc.) necessary for executing each installed application.

  When the computer 10 is in a normal operation state, normally, the service program, the device driver program, and the like should be in an execution state, so that the execution of the AV application program 101 is not affected. However, since there are cases where the service program, device driver program, and the like are stopped by a user operation, the AV application program 101 is a service program that should operate in cooperation with the AV application program 101 at the time of activation. A status check process is executed to check the status of the correct program. If it cannot be confirmed that the specific program is in an execution state immediately after starting the state check process, the AV application program 101 confirms that the specific program is in an execution state. For example, it waits for a predetermined time-out period that does not stress the user. If it is not confirmed that the specific program is in the running state even after waiting for this timeout period, that is, the specific program is executed during the period from the start of the status check process until the timeout period elapses. If the AV application program 101 is not confirmed to be in the state, the AV application program 101 determines that the operating environment necessary for the AV application program 101 to operate normally is not prepared, and displays a message indicating an error (error message). Output.

  The time-out time (waiting time) that does not give stress to the user is at most about several seconds. Therefore, the AV application program 101 can wait only about several seconds for the start of execution of a specific program such as a service program. When the AV application program 101 is started immediately after the computer 10 is started, that is, immediately after the operating system 102 is started, a specific program such as a service program or a device driver that cooperates with the AV application program 101 for a period of about several seconds. May not be ready in time. In this case, there is a phenomenon in which a specific program such as a service program or a device driver is treated as an error even if it waits for a while, even though it enters an execution state.

  Note that if the timeout time is set to be uniquely long, it takes a lot of time to display the error message in a situation where there is a real problem and timeout occurs.

  Therefore, in the present embodiment, the AV application program 101 is provided with a function for automatically adjusting the length of the timeout time. That is, when the AV application program 101 is activated, the AV application program 101 determines whether or not the operating system 102 has already completed environment startup processing for activating a program group such as a service program and a device driver. According to the determination result, the length of the timeout time is automatically adjusted. To determine whether or not the environment startup processing has been completed, an elapsed time from when the operating system 102 is activated until the AV application program 101 is activated is used. If this elapsed time exceeds a certain time, the AV application program 101 determines that the environment startup processing has been completed, and performs state check processing using a normal timeout time. On the other hand, if the elapsed time is within a certain time, the AV application program 101 determines that the environment startup processing has not been completed, and performs state check processing using a timeout time longer than the normal timeout time.

  Thus, in the present embodiment, the timeout time is automatically adjusted according to the elapsed time since the operating system 102 is started. Therefore, even when the AV application program 101 is started immediately after the operating system 102 is started, it is possible to suppress the occurrence of an error due to insufficient waiting time as described above.

  Further, the CPU 111 also executes a basic input / output system (BIOS) stored in the BIOS-ROM 120. The BIOS is a program for hardware control.

  The north bridge 112 is a bridge device that connects the local bus of the CPU 111 and the south bridge 119. The north bridge 112 also includes a memory controller that controls access to the main memory 113. The north bridge 112 also has a function of executing communication with the graphics controller 114.

  The graphics controller 114 is a display controller that controls the LCD 17 used as a display monitor of the computer 10. The graphics controller 114 displays the image data written in the video memory (VRAM) 114 A by the operating system 102 or the AV application program 101 on the LCD 17. The south bridge 119 controls each device on an LPC (Low Pin Count) bus and each device on a PCI (Peripheral Component Interconnect) bus. The south bridge 119 incorporates an IDE (Integrated Drive Electronics) controller for controlling the HDD 121 and the ODD 122.

  Further, the south bridge 119 includes a real time clock (RTC) 119A. The real-time clock (RTC) 119A functions as a clock module that measures the current date and time (year, month, day, hour, minute, second). In a register (RTC register) in the real-time clock (RTC) 119A, an alarm time for designating the time (year, month, day, hour, minute, second) at which the computer 10 should be turned on can be set. A real-time clock (RTC) 119A is a power-on event indicating that the computer 10 should be powered on when the current time reaches the alarm time set in the RTC register by the TV application program 101 via BIOS or the like. Is notified to the EC / KBC 124. In response to the occurrence of this power-on event, the EC / KBC 124 powers on the computer 10.

  The tuner devices 123A and 123B are receiving devices that receive broadcast program data broadcast by broadcast signals. In the present embodiment, for example, the tuner device 123A is composed of an analog TV tuner that receives broadcast program data broadcast by an analog broadcast signal, and the tuner device 123A receives broadcast program data broadcast by a terrestrial digital broadcast signal. It consists of a receiving digital TV tuner.

  The EC / KBC 124 is a one-chip microcomputer in which an embedded controller for power management and a keyboard controller for controlling the keyboard (KB) 13 and the touch pad 16 are integrated. The EC / KBC 124 has a function of powering on / off the computer 10 in accordance with the operation of the power button 14 by the user. The operation power supplied to each component of the computer 10 is generated from a battery 126 built in the computer 10 or an external power supply supplied from the outside via the AC adapter 127. The EC / KBC 124 is also connected to the remote control unit interface unit 20.

  The AV application program 101 can be controlled not only by the user operating the input device such as the keyboard (KB) 13 and the touch pad (mouse) 16 but also by operating an external remote control unit.

  The network controller 125 is a communication device for connecting to a wired or wireless network, and is used to execute communication with an external network such as the Internet.

  Next, the functional configuration of the AV application program 101 will be described with reference to FIG.

  The AV application program 101 has a program module group for executing the above-described TV function and AV data library function. These program module groups operate in cooperation with a service program, an SQL database service program, a device driver program, etc., and receive necessary services from the service program by, for example, performing message communication with a certain service program. .

  The AV application program 101 includes an elapsed time detection unit 201, a timeout time selection unit 202, and an error output unit 203 as program modules for executing the above-described automatic timeout time adjustment function.

  When the AV application program 101 is activated by a user operation or by automatic activation for the above-described reservation recording, the elapsed time detection unit 201 detects an elapsed time from when the operating system 102 was last activated to the present. When the operating system 102 is started by a cold boot or restart, the operating system 102 starts counting elapsed time. The elapsed time detection unit 201 can acquire, from the operating system 102, the elapsed time since the operating system 102 was last activated through an API such as GetTickCount prepared in the operating system 102.

  The timeout time selection unit 202 compares the elapsed time detected by the elapsed time detection unit 201 with a predetermined environment startup time. The environment startup time is an estimated value of the time required from the start of the operating system 102 to the completion of the environment startup processing. This value is determined in advance according to, for example, the system performance, the type of the operating system 102, and the like. It has been. When the elapsed time exceeds the environment startup time, the timeout time selection unit 202 selects a normal timeout time (first timeout time) as a timeout time to be used. On the other hand, if the elapsed time is within the environment startup time, the timeout time selection unit 202 selects a timeout time (second timeout time) longer than the normal timeout time as the timeout time to be used.

  The error output unit 203 executes a state check process of a predetermined program such as a service program that should operate in cooperation with the AV application program 101. If it is not confirmed that the predetermined program is in the execution state during the period from the start of the state check process until the selected timeout time elapses, the error output unit 203 generates an error or In order to notify the user of the error content and the like, a message (error message) indicating the occurrence of the error is output. The error message is displayed on the display screen of the LCD 17, for example.

  Next, a processing procedure executed when the AV application program 101 is started will be described with reference to the flowchart of FIG.

  When the AV application program 101 is activated, the AV application program 101 first acquires an elapsed time from when the operating system 102 is activated to the present time (step S11). In this step S11, an acquisition request message such as GetTickCount is transmitted from the AV application program 101 to the operating system 102, and a value indicating the elapsed time managed by the operating system 102 is returned to the AV application program 101.

  Next, the AV application program 101 determines whether or not the elapsed time acquired from the operating system 102 is within the above-described environment startup time (step S12). The environment startup time is set to about 5 minutes, for example.

  If the elapsed time exceeds the environment startup time (NO in step S12), the AV application program 101 selects a normal timeout time (first timeout time) and should be used in the status check process. Is set to the first timeout time (step S13). The first time-out time is a waiting time on the assumption that a necessary service program or the like is already in an execution state, and this value takes into consideration that the user is not stressed and a delay due to message communication or the like. For example, it is set to about 5 seconds.

  On the other hand, if the elapsed time is within the environment startup time (YES in step S12), the AV application program 101 sets the timeout time (second timeout time) longer than the normal timeout time (first timeout time). Is selected, and the timeout time to be used in the state check process is set as the second timeout time (step S14). The second timeout time is a waiting time on the assumption that processing for starting a required service program or the like is not completed, and this value is, for example, 1 to 1, considering the time required for starting the service program or the like. It is set to about 2 minutes.

  Next, the AV application program 101 executes a status check process for checking the status of a predetermined program such as a necessary service program (step S15). Then, when it is not confirmed that the predetermined program is in an execution state during the period from the start of the state check process until the set timeout time elapses (YES in step S15), the AV application program 101 determines that the operating environment necessary for the operation of the AV application program 101 is not prepared, and displays an error message (step S16).

  For example, whether or not a certain service program is in an execution state is determined by, for example, transmitting a request such as a processing request from the AV application program 101 to the service program as shown in FIG. This can be done by counting the waiting time T until a response is returned to the application program 101. If this waiting time T exceeds the set timeout period, that is, if a response is not returned during the period from when a request is sent to the service program until the timeout period elapses, a timeout error will occur. Detected.

  Further, it is possible to determine whether or not a certain service program is in an execution state by inquiring about the state of the service program as shown in FIG. In this case, the AV application program 101 repeatedly inquires the service manager, which is a service management program operating on the operating system 102, about the state of a predetermined service program until it is confirmed that the service program is in an execution state. Then, the AV application program 101 counts a waiting time T from when the inquiry is started until it is confirmed that the predetermined service program is in an execution state. If this waiting time T exceeds the set time-out period, that is, if it is not possible to confirm that the service program is in an execution state during the period from the start of inquiry until the time-out period elapses, time-out will occur. The occurrence of an error is detected.

  The service manager manages the state of each service program (execution state, stop state, state during transition processing to execution state, state during transition processing to stop state, etc.) In response to the status inquiry, the application program is notified of the current status of the service program designated by the inquiry. The execution state of the service program means that the service program service is started and the service program can be used from the application program.

  Even if there are a plurality of service programs that should operate in cooperation with the AV application program 101, if the association between the plurality of service programs is registered in the operating system 102 in advance, It is sufficient to check only the status of one service program. This is because, basically, all the associated service program groups are activated by the operating system 102, only one service program is activated, and no other service program is activated.

  Next, processing for adaptively adjusting the value of the second timeout period described above will be described with reference to the flowchart of FIG.

  In the processing described with reference to FIG. 4, it is assumed that the value of the second timeout time is determined in advance, but in this example, the elapsed time after the operating system 102 is started is within the environment startup time. If there is, the value of the second timeout time is calculated based on the remaining time until the environment startup time.

  In other words, if the elapsed time acquired from the operating system 102 is within the environment startup time, the AV application program 101 first subtracts the elapsed time from the environment startup time and remains until the environment startup time is reached. Time is calculated (step S21). Next, the AV application program 101 calculates the total time of the calculated remaining time and the normal timeout time (first timeout time) (step S22), and sets the total time as the second timeout time (step S22). S23).

  With this process, since the final error determination is not performed at least until the time when the environment startup time elapses after the operating system 102 is started, the AV application program 101 is started during the service program execution preparation period. It is possible to more efficiently reduce the occurrence of a timeout error due to being performed.

  Next, a series of processes from when the computer 10 is powered off until the TV application program 101 is automatically started will be described with reference to the flowchart of FIG.

  The TV application program 101 manages a database that stores recording reservation information for designating broadcast program data reserved for recording. This database is stored in a predetermined storage area in the HDD 121, for example. For example, the TV application program 101 sets, for example, about 15 minutes before the recording start time of broadcast program data to be reserved and recorded in the RTC 119A as the next power-on time through the BIOS.

  When the computer 10 is powered off, the EC / KBC 124 automatically powers the computer 10 in response to a power-on event from the RTC 119A when a predetermined time (for example, 15 minutes) before the recording start time. Turn on. Then, under the control of the BIOS, an automatic power-on process (step S31) including a process for initializing each device of the computer 10 is executed. In response to the computer 10 being powered on, the BIOS starts an OS activation process for activating (booting) the operating system 102 (step S32).

  When the operating system 102 is started, processing for starting various service programs (steps S33 and 34), processing for starting the AV application program 101 (step S35), and the like under the control of a scheduling program in the operating system 102, etc. Is executed.

  As described above, when the AV application program 101 is automatically activated, the AV application program 101 is activated immediately after the operating system 102 is activated. When the AV application program 101 is activated, the AV application program 101 starts the processing described in the flowchart of FIG.

  If the timing at which the AV application program 101 is activated is before completion of the environment startup process, the second timeout time is selected. If it is not confirmed within the second time-out period that the required service program is in the running state, the AV application program 101 generates an error message and terminates in error. On the other hand, if it is confirmed within the second time-out period that the necessary service program is being executed, the AV application program 101 starts preparation for recording processing of broadcast program data reserved for recording.

  As described above, according to the present embodiment, when the AV application program 101 is started during the normal operation period by automatically adjusting the timeout time according to the elapsed time from the startup of the operating system. When the AV application program 101 is started immediately after the operating system is started using a normal timeout time, a timeout time longer than the normal timeout time can be used. Therefore, it is possible to efficiently prevent the occurrence of a timeout error due to the activation of the application program during the execution preparation period of the program that should operate in cooperation.

  In particular, when the computer 10 is automatically started according to the recording start time of broadcast program data reserved for recording, the AV application program 101 is likely to be started immediately after the operating system 102 is started. The time-out time automatic adjustment function can efficiently prevent the occurrence of a time-out error. Therefore, it is possible to greatly reduce the possibility that the reservation recording process will fail.

  Since all functions of the AV application program 101 of the present embodiment can be realized by software, the same effects as those of the present embodiment can be obtained simply by installing this software into a normal computer through a computer-readable storage medium. Can be easily realized.

  Further, the control of the present embodiment can be applied not only to AV application programs but also to all application programs that operate in cooperation with other programs.

  Further, the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, you may combine a component suitably in different embodiment.
