For example, the control unit 11 includes a plurality of microprocessors. Moreover, the control part 11 is provided with the several function part shown in FIG. 1 mentioned later as a function part implement | achieved by running a program on the arithmetic processing apparatus with which the control part 11 is provided.

  The memory 12 is a medium for temporarily recording various data held by the BD recorder 1, and is composed of, for example, a writable RAM (Random Access Memory). The memory 12 has a role as a buffer memory for temporarily recording, for example, processing data when various kinds of information processing are performed by the control unit 11 and instruction commands received from the user.

In the case of a digital system, a digital tuner, an error correction unit, and the like are included.

  For example, when receiving a digital broadcast, a digital tuner included in the broadcast receiving unit 17 performs amplification and detection of the intermediate frequency signal. Thereby, TS (= Transport Stream) which is a digital signal of the MPEG2 system is acquired. Note that the TS is an audio PES (Packetized Elementary Stream), an image PES, and additional information of a plurality of programs divided into fixed-length TS packets and connected. The signal is supplied to the signal processing unit 18 and converted into an image / audio signal. It is also possible to record the TS in the HDD 14 without converting it.

The details of the internal structure of the server 3 are the same as those of the prior art, and thus the description thereof is omitted.
<2. About the configuration of the function section>

  Here, the relationship of each function part for the BD recorder 1 which concerns on one Embodiment of this invention to implement a log transmission process is demonstrated, using 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 log transmission processing of the present invention is performed by the Linux (registered trademark) kernel 11a, the application group 11b, and the log control unit 11c (= history generation unit) included in the control unit 11.

  The Linux kernel 11a creates a log buffer (buffer area) that is a log storage buffer shared by the Linux kernel and the application in the memory 12 or the HDD. And the application log which the application group 11b mentioned later produces | generates is copied to a log buffer. The Linux kernel 11a performs communication control for mutual communication with an external device connected via the external connection terminal 20, such as the server 3.

  The application group 11b includes a plurality of applications. Each application is realized by an arithmetic processing device included in the control unit 11 executing an application program recorded in advance in the ROM 15. Each application individually generates an application log and transmits it to the Linux kernel 11a. For example, a recording application for performing a recording process generates an application log related to the recording process, for example, an application log indicating a recording start time.

  Note that the applications included in the application group 11b of the present embodiment do not have individual functions related to application log accumulation and application log transmission via the network. For this reason, the transmission destination of the application log is only the Linux kernel 11a.

  The log control unit 11c acquires log data from the log buffer. In addition, the log control unit 11c instructs the Linux kernel 11a to transmit log data to an arbitrary transmission destination. Receiving this instruction, the Linux kernel 11a transmits log data to an external device designated by the log control unit 11c, for example, the personal computer 2 or the server 3.

  Further, the log control unit 11c performs authentication with the log receiving tool installed in the personal computer 2 or the server 3, and transmits the log only to the permitted log receiving tool. The log transmission destination is not necessarily limited to the information processing apparatus. For example, the log may be output to a USB memory connected to a USB terminal included in the external connection terminal 20.

  In addition, the log control unit 11c receives designation of a transmission destination for transmitting the application log (= first history information) and the kernel log (= second history information) in a predetermined unit from the user. In addition, designation of permission / prohibition of log transmission is accepted from the user in units of logs. As a method for accepting the designation, for example, a setting screen for accepting the designation is displayed by the OSD processing unit 19 and a user operation is accepted by the operation unit 13.

  Next, details of the log data generated in the log buffer by the log control unit 11c will be described with reference to FIGS. FIG. 5 is an example of an application log generated by the application A included in the application group 11b. FIG. 6 is an example of an application log generated by the application B included in the application group 11b. FIG. 7 is an example of a kernel log generated by the Linux kernel 11a. FIG. 8 is an example of log data stored in the log buffer.

As shown in FIG. 8, the log data stored in the log buffer is stored in the time series in which a plurality of logs are generated. In FIG. 8, the application log generated by application A corresponds to (A), the application log generated by application B corresponds to (B), and the kernel log corresponds to (C). The log control unit 11c instructs the Linux kernel 11a to transmit log data according to the accumulation order.
<3. About log transmission processing>

  Here, log transmission processing performed by the BD recorder 1 according to an embodiment of the present invention will be described with reference to the flowcharts of FIGS. 3 and 4. FIG. 3 shows a processing flow in which log data in the log buffer is transmitted in a batch. FIG. 4 shows a processing flow in which the log data in the log buffer is sorted and transmitted. In FIG. 3 and FIG. 4, description of the same processing is omitted by assigning the same step number.

  Up to this point, the processing flow of the form in which log data in the log buffer shown in FIG. After the start of this process, the control unit 11 activates the Linux kernel 11a in step S110.

  Next, in step S120, the control unit 11 activates the log control unit 11c. Next, the Linux kernel 11a initializes the log buffer in step S130.

  In step S140, the log control unit 11c performs log data transmission setting. Next, the Linux kernel 11a activates the application group 11b in step S150. Thereby, the recorder application etc. which are contained in the application group 11b are started.

  Next, in step S160, a predetermined application (recorder application in the present embodiment) included in the application group 11b starts transmitting application logs to the Linux kernel 11a. In response to this, the Linux kernel 11a accumulates the received application log in the log buffer in step S170. At the same time, the kernel log generated inside the kernel is accumulated in the log buffer.

  In step S180, the log control unit 11c reads log data from the log buffer. In step S190, it is determined whether or not the read log data exceeds a predetermined data amount.

  If it does not exceed the predetermined amount of data, the process proceeds to step S170 again. If the predetermined amount of data is exceeded, then in step S200, the log control unit 11c instructs the Linux kernel 11a to transmit the log data read from the log buffer by TCP / IP communication. The destination is specified by, for example, an IP address.

  Next, in step S210, the Linux kernel 11a transmits a log to the transmission destination specified above. As a result, log data is transmitted to the personal computer 2 or the server 3 or the like. When the transmission is completed, this process is terminated.

  Next, a description will be given of the processing flow of the form shown in FIG. 4 in which logs are sorted and transmitted in the log buffer. Steps S110 to S130 are the same as those in FIG. After step S130, the log control unit 11c performs log data transmission setting in units of process IDs in step S141.

  Steps S150 to S170 are the same as those in FIG. After step S170, in step S171, the log control unit 11c determines, for each log data, the ID of the process that generated the log data, and stores these in the log buffer in association with each other.

  Next, in step S181, the log control unit 11c reads log data and a process ID associated with the log data from the log buffer. In step S190, if the read log data exceeds a predetermined amount of data, the log control unit 11c selects a plurality of log data read from the log buffer in step S201 according to the associated process ID. The Linux kernel 11a is instructed to transmit to the destination. When the Linux kernel 11a that has received the message transmits a log in step S210, the process ends.

  According to the present embodiment described above, even if the BD recorder 1 is mounted with an application that does not have a function of accumulating application logs or a function of transmitting application logs, the kernel of the OS (Linux in this embodiment) A log and a plurality of application logs can be transmitted to the personal computer 2 and the server 3 at once. For this reason, there is no need to implement a log transmission function for each application.

  Further, according to the present embodiment, log output destinations can be switched at once. Further, log data can be classified into a plurality of pieces based on the process ID and the like, and individually transmitted to a plurality of destinations. In addition, since a log is output using a communication network such as a LAN, a special jig is not required unlike serial communication.

  In the above two embodiments, transmission is performed mainly by the BD recorder 1, but conversely, a request from the personal computer 2 may be waited and log data may be transmitted only when the request is received.

  In the case of this embodiment, when the log control unit 11c is activated in step S120, the log control unit 11c functions as a log distribution server. Thereafter, a predetermined amount of log data is accumulated in the log buffer in steps S130 to S190.

  In step S200, when the log reception tool (client tool) installed in the personal computer 2 is activated and receives a log transmission request from the log reception tool, authentication is performed between the log control unit 11c and the log reception tool. Process. If the authentication is successful, the process proceeds to step S210, and the log data is transmitted to the personal computer 2 that is the transmission source of the request.

If the log is sorted by process ID as in the embodiment shown in FIG. 4, the log data to be transmitted when a request is received from the personal computer 2 is determined based on the process ID associated with the log data. Alternatively, only the determined log data may be transmitted to the personal computer 2.
