<2. About the configuration of the function section>

  Here, the relationship of each functional unit for the HDD recorder 1 according to an embodiment of the present invention to perform the failure detection processing of the present invention will be described with reference to the block diagram of FIG. In addition, the broken-line arrow line in FIG. 1 has shown the flow of the control signal.

  As shown in FIG. 1, the failure detection process of the present invention is performed by the activation processing unit 11a, the failure detection unit 11b, the activation control unit 11c, the communication control unit 11d, and the setting unit 11e included in the control unit 11.

  The activation processing unit 11a controls each unit of the HDD recorder 1 so that the activation process is performed in a predetermined activation sequence (= activation procedure) when the main power supply of the HDD recorder 1 is activated.

  For example, the activation processing unit 11a performs inspection / activation for each module (= device group) in which the devices included in the HDD recorder 1 are grouped in units of functions. Accordingly, each processing step of the activation sequence includes in advance identification information indicating a module to be inspected / activated.

  As a module unit, for example, a device group corresponding to each function such as a reproduction function and a network function is defined as one module. In the example of FIG. 2, the optical disk drive 16 and the communication I / F 20 are one module. However, the method of determining a module is not limited to this, and a module may be formed in units smaller or larger as long as it is a functional unit that can use a predetermined service.

  The failure detection unit 11b monitors whether or not a failure has occurred in each unit of the HDD recorder 1. Specifically, the failure detection unit 11b inspects each module when the HDD recorder 1 is activated. When a failure is detected, a counter that counts the number of failure detections for each module is counted up. When a module is generated in which the number of times counted up exceeds a predetermined number, failure detection information indicating the module is recorded in the flash memory 14 or the like.

  When the activation processing is started by the activation processing unit 11a, the activation control unit 11c reads and refers to the failure detection information, and determines a module in which a failure has occurred. Then, the activation processing unit 11a is controlled so as to perform the activation process by excluding the processing steps for the module from the activation sequence.

  The communication control unit 11d performs communication control for performing mutual communication with an external device connected by the communication I / F 20, such as a mail server or an information distribution server. Thereby, it is possible to send and receive e-mails and acquire various information contents. Further, when the communication I / F 20 includes a wireless antenna, it also has a role of controlling wireless communication via the wireless communication network.

  The setting unit 11e receives various settings regarding processing performed by each functional unit from the user. For example, it accepts whether or not the activation process by the activation control unit 11c as a target of the failed module, the setting of a communication destination with which the communication control unit 11d performs communication, and the like. The setting information indicating the setting contents is recorded in the flash memory 14 or the HDD 15.

  Specifically, the setting unit 11e controls the OSD processing unit 19 so as to generate, for example, an image signal for displaying the setting screen 200 shown in FIG. Then, the generated image signal is output to the display 2 via the external connection terminal 21. Thereby, the setting screen 200 is displayed on the display 2.

  As shown in FIG. 4, the setting screen 200 includes a message window 201 and a cursor 202. The user can select the “Yes” button or the “No” button included in the message window 201 by moving the cursor 202 using the operation unit 13 or the remote controller 100.

When a determination button (not shown) included in the operation unit 13 is pressed while the cursor 202 is positioned on the “Yes” button, the setting unit 11e causes a failure to perform failure detection processing described below. The detection unit 11b and the activation control unit 11c are instructed.
<3. About failure detection processing>

  Here, the failure detection processing of the present invention performed by the HDD recorder 1 according to an embodiment of the present invention will be described with reference to the flowchart of FIG. The process shown in FIG. 3 is started when the power source of the HDD recorder 1 is activated.

  After the start of this process, the failure detection unit 11b performs inspection and activation confirmation of each device included in the HDD recorder 1 in step S110.

  Next, in step S120, the failure detection unit 11b branches the process depending on whether or not a device having a failure as a result of the above is detected. When no failure device is detected, the activation processing unit 11a performs activation processing according to a normal activation procedure, and ends this processing. When a failure device is detected, the failure detection unit 11b counts up the number of failure detections of a module (hereinafter referred to as “failure detection module”) including the device that has detected the failure in step S130.

  Next, in step S140, the activation control unit 11c checks whether or not the failure detection frequency of the failure detection module has exceeded a predetermined threshold value. Specifically, a failure detection report indicating the number of past failure detections is read from the flash memory 14 and checked by comparing it with a threshold value. When there are a plurality of failure detection modules, individual confirmation is performed for all failure detection modules.

  Next, in step S150, the activation control unit 11c branches the process depending on whether there is a failure detection module whose failure detection count exceeds the threshold. If there is no failure detection module exceeding the threshold value, the activation control unit 11c instructs the activation processing unit 11a to perform activation processing for the activation target pair only for the current activation in step S151. To do. As a result, the functions performed by the corresponding failure detection module cannot be used by the user until the next power-on.

  If there is a failure detection module exceeding the threshold, the activation control unit 11c instructs the activation processing unit 11a to continuously exclude the module from being activated in step S160. Accordingly, the activation processing unit 11a does not activate the corresponding module in the subsequent activation processing.

  More specifically, each step of the activation sequence includes in advance identification information indicating a module to be inspected / activated by each step. When executing each step, the activation processing unit 11a confirms the failure state of the module indicated by the identification information, thereby determining whether to skip the corresponding step and executing the activation sequence.

  In addition, the activation control unit 11c instructs the failure detection unit 11b to continuously exclude the module from the inspection target. Thereby, the failure detection unit 11b does not inspect the corresponding module when performing step S110.

  Next, in step S170, the activation processing unit 11a controls the OSD processing unit 19 so as to generate an image signal for displaying the notification screen 300 shown in FIG. Then, the generated image signal is output to the display 2 via the external connection terminal 21. Thereby, the notification screen 300 is displayed on the display 2.

  As shown in FIG. 5, the notification screen 300 includes a message window 301 and a cursor 302. The message window 301 displays a message indicating that a failure has been detected and that the function has been started with a restriction on functions related to the failure location. Further, when the same failure as this time is detected at the next start-up, a message prompting the user to select whether or not to display the same notification screen 300 is displayed.

  The user can select the “Yes” button or the “No” button included in the message window 301 by moving the cursor 302 using the operation unit 13 or the remote controller 100.

  When a determination button (not shown) included in the operation unit 13 is pressed while the cursor 302 is positioned on the “Yes” button, the same notification screen will be displayed at the next startup unless the failure location is restored from the failure state. 300 is displayed. If the determination button included in the operation unit 13 is pressed while the cursor 302 is positioned on the “No” button, the knowledge screen 300 is not displayed at the next activation. However, when a new failure location is detected, a notification screen 300 is displayed.

According to the present embodiment described above, a module in which a failure has been detected more than a predetermined number at the time of activation is excluded from inspection / activation from the next activation. As a result, it is possible to avoid a situation in which the startup time is long due to a retry to the device included in the failure detection module. In addition, it is possible to avoid a situation where a load is applied to the failure device due to the retry and causes a new failure.
