  Next, how the TV recording device 1 performs the recording operation in cooperation with the mobile terminal device 2 will be described in an embodiment. Here, the case where the mobile terminal device 2 is a smartphone 2a and a smart watch 2b will be described separately.

  Example 1 demonstrates the case where the smart phone 2a is used as the portable terminal device 2. FIG. The television recording apparatus 1 determines that the user is paying attention to the viewing program based on information from the smartphone 2a carried by the user as follows, and starts recording. Conversely, if it is determined that the user is not paying attention, the recording is stopped.

The basic rule in this case is as follows.
(A) When the effective viewing time Δt during which the user continues to watch the same program (CH) exceeds a predetermined time Δt1 (for example, 5 minutes), it is determined that the user likes the program and recording is performed. To start.
(B) If the user starts using the smartphone while watching a program, it is determined that the user is not interested in the program, and recording is stopped.
(C) However, in (b), when information related to a program is acquired by a smartphone, it is determined that the program is interested and recording is continued or resumed. In this case, since there is a possibility that program viewing has been missed, the recording may be resumed retroactively by a predetermined time Δt2 (referred to as time-shift recording).

  A specific example of the above (c) will be described. Suppose you are watching a "Le Mans 24 Hours Auto Racing" on a TV program. At that time, when accessing the broadcasting station site, the official race site, and other motor sports such as the F1 site, or operating the Le Mans 24 Hours official app on the smartphone 2a, Acquire. At this time, the smartphone 2a transmits the accessed site and application information to the TV recording device 1, and the TV recording device 1 determines that “the smartphone is used but is related to the program”, and the recording is performed. Continue.

  FIG. 4 is a diagram illustrating an example of a recording operation in cooperation with the smartphone 2a. FIG. 4 is a time chart showing the relationship between the TV viewing period, the operation period of the smartphone (hereinafter abbreviated as “smartphone”), and the recording operation. As the recording operation, three patterns (A) to (C) will be described. The user's television viewing channel is switched from CH1 (period 301) to CH2 (period 302) and again to CH1 (period 303). On the other hand, the user operates the smartphone intermittently during periods 311, 312, and 313. During these periods, the user is not watching the program. Among these, the operation in the period 313 is for acquiring the program related information of CH1.

  In this embodiment, a period in which the same CH is continuously viewed and a smartphone operation (except for acquisition of program related information of CH1) is not performed is defined as an “effective viewing period”. In FIG. 4, during the CH1 viewing period 303, periods 321 and 322 excluding the smartphone operation periods 311 and 312 are effective viewing periods. The length of the effective viewing period is set to “effective viewing time” and is measured by the timer 111. The length of the effective viewing time is compared with a predetermined time Δt1, and a plurality of timing positions P1 to P7 are determined.

  As examples of the recording operation, three patterns (A), (B), and (C) will be described. (A) is basic, and (B) and (C) are variations thereof.

<Recording operation (A)>
(P2): After stopping the smartphone operation (311), since the effective viewing time (321) of CH1 exceeds the predetermined time Δt1, recording (331) of CH1 is started.
(P3): Since the smartphone operation (312) is started again, the recording (331) is stopped. At this time, the recorded part may be erased.
(P5): After the operation (312) of the smartphone is stopped, the effective viewing time (322) of CH1 exceeds the predetermined time Δt1, so the recording (332) of CH1 is resumed.
(P6-P7): A smartphone operation (313) is performed, but since the operation content is acquisition of program-related information of CH1, recording (332) is continued.
According to this method, since the recording operation is performed according to the length of the effective viewing time, recording can be resumed many times during the program.

<Recording operation (B)>
(P2-P3): Similar to the recording operation (A), the recording (331) of CH1 is started / stopped.
(P5): The effective viewing time (322) of CH1 has exceeded the predetermined time Δt1, but recording is not resumed at this point. That is, if the smartphone operation (312) is performed during recording, it is determined that the program is not interested and the subsequent recording is not resumed.
(P7): Since the smartphone operation (313) is for acquiring the program related information of CH1, it is determined that the user is interested in the program, and the recording (333) of CH1 is resumed.
According to this method, the fact that CH1 has been recorded as a favorite once (period 331) is stored, so that recording can be resumed triggered by a related smartphone operation.

<Recording operation (C)>
(P2-P3): Similar to the recording operation (B), the recording (331) of CH1 is started / stopped. In (P5), recording is not resumed.
(P7): Since the smartphone operation (313) is for acquiring the program related information of CH1, it is determined that the program is interested in the same manner as the recording operation (B), and the recording of CH1 (334) is resumed. However, in this case, the recording is resumed by going back a predetermined time Δt2 from the time point (P7) (time shift recording). Although this time Δt2 depends on the recording capacity of the ring buffer, it is desirable to record using this to the maximum.
This method is effective in the case of all program recording by the ring buffer method, and by starting recording after a predetermined time, it is possible to view without missing a favorite program.

  FIG. 5 is a flowchart showing the recording control of FIG. Here, the case of the recording operation (A) in FIG. 4 will be described. The following processing is controlled by the CPU 101 of the television recording apparatus 1.

  In S401, the time measuring unit 111 starts measuring the effective viewing time Δt of the user. The effective viewing time Δt is a time during which the user continuously views the same CH (same program) and the user is not performing a smartphone operation.

  In S402, it is determined whether or not the user continuously views the same CH (same program). This is determined by whether or not the same CH (same program) is continuously output from the video processing unit 109. If the same CH is viewed, the process proceeds to S403. If there has been a CH change since the previous determination, the process proceeds to S405.

  In S403, it is determined whether or not the user is performing a smartphone operation. As for the presence / absence of the user's smartphone operation, the operation status of the mobile terminal device (smart phone 2a) can be known via the communication unit 106 (particularly, the short-range wireless communication unit 106b). If the smartphone is being operated, the process proceeds to S404, and if not, the process proceeds to S406.

In S404, it is determined whether or not the smartphone operation content is related to the currently viewed program. Therefore, the program information stored in the RAM 103 is referred to and compared with the operation content of the smartphone (such as a search keyword). If a keyword or the like matches or is similar, it is determined to be related. If related, the process proceeds to S406, and if not related, the process proceeds to S405.
In S405, the effective viewing time Δt = 0 is reset, and the process proceeds to S408.

  In S406, the current effective viewing time Δt is read, and it is determined whether or not the predetermined time Δt1 is exceeded. The predetermined time Δt1 can be appropriately set by the user, and is set to 5 minutes, for example. If the effective viewing time Δt exceeds the predetermined time Δt1, the process proceeds to S407, and if it does not exceed the predetermined time Δt1, the process proceeds to S408.

In step S407, the recording unit 104 is instructed to start viewing CH recording. If recording is already in progress, recording continues.
In step S408, the recording unit 104 is caused to stop the recording operation. Moreover, you may delete the recorded part as needed.

In S409, the program information is referred to and it is determined whether or not the viewing program end time has been reached. If the end time has been reached, the process proceeds to S410 and the recording operation of the viewing program ends. If the end time has not been reached, the process returns to S402 and the above-described series of processing is repeated.
By executing the processing loop described above at a predetermined time interval (for example, every 1 minute), the recording control shown in the recording operation (A) of FIG. 4 can be realized.

  Note that the recording operation (B) in FIG. 4 is stored so that the number of recording operations of the same program is stored, and the second and subsequent recording restart operations are changed to be executed when a program-related smartphone operation is performed. . As for the recording operation (C) of FIG. 4, when all programs are recorded in the ring buffer method in advance and the recording resuming operation associated with the program-related smartphone operation is performed, the time-shift recording is performed retroactively by a predetermined time Δt2. Just change it to do.

Here, as to whether or not the smartphone operation is related to the viewing program (S404), the smartphone operation may be performed for e-mail or SNS (Social Network Service). It is preferable to do this.
(1) When an external interruption such as e-mail or SNS is received, it is determined that “there is a program related” because the smartphone is not operated because the user gets tired of the program. This determination includes a reply to e-mail and SNS, does not detect whether the contents are unrelated to the program, and does not use it as a determination material. Further, even if this operation is accompanied by browsing or replying to other e-mails or SNSs that are not related to the program, it is not detected whether it is unrelated to the program, and is not used as a judgment material.

(2) When writing an e-mail or SNS voluntarily, it is determined that the program is not related in principle. However, if the content written to the e-mail or SNS is related to a program, it may be determined that “the program is related”.
(3) Even when the mail or SNS is voluntarily written, if the contents of the mail or SNS are related to the viewing program (when the description of the title, actor, etc. matches) It is determined that it is liked and “program related”.
(4) When performing a smartphone operation such as voluntarily viewing a program-related site, it is determined that “program related”.

  According to the first embodiment, it is possible to easily determine the degree of attention of the user with respect to the viewing program via the smartphone and efficiently perform automatic recording.

  In the second embodiment, a case where a smart watch 2b is used as the mobile terminal device 2 will be described. The television recording apparatus 1 determines that the user is paying attention to the viewed program based on information from the smart watch 2b worn on the hand as follows, and starts recording. Conversely, if it is determined that the user is not paying attention, the recording is stopped. If it is determined that the user is sleeping while viewing, the recording is started retroactively.

The basic rule in this case is as follows.
(A) The pulse of the user who is watching the program is measured by the smart watch, and when the pulse increases or irregularly increases / decreases, it is determined that the user likes the program and recording is started.
(B) When it is detected that the user's pulse is low and stable and the acceleration sensor detects no movement of the user, the user is determined to be sleeping. In this case, since there is a possibility that program viewing has been missed, recording is started retroactively for a predetermined time (time shift recording).
(C) When it is determined that the user's pulse is low and stable and the user is waking up by the acceleration sensor, the user determines that he / she does not like the program so much and stops recording.
Next, an example of a recording operation in cooperation with the smart watch 2b will be described.

  FIG. 6 is a flowchart showing a recording operation in cooperation with the smart watch. The following processing is controlled by the CPU 101 of the television recording apparatus 1.

  In S501, the user's pulse M is measured and acquired by the smart watch 2b worn by the user. This operates the pulse sensor 207g of the smart watch 2b via the communication unit 106 (particularly, the short-range wireless communication unit 106b) to acquire the user's pulse M.

In S502, the acquired pulse M is compared with the normal pulse M0. Here, the normal pulse M0 of the user may be acquired from the smart watch 2b, or may be stored in advance in the RAM 103 of the television recording device 1. The determination result of the pulse M is divided into the following three types.
(1) When the pulse M is higher than the normal pulse M0 (M> M0), it is determined that the user is excited to see the program, that is, the user likes the program, and the process proceeds to S504.
(2) If the pulse M is irregularly increasing / decreasing, it is determined that the user is excited to see the program, that is, the user likes the program, and the process proceeds to S504. At this time, if the upper and lower patterns of the pulse are compared with the scene switching of the program and the strength of the sound, and it is confirmed or determined that there is a correlation, it can be determined whether or not the program is favorably or accurately determined. It becomes possible.
(3) If the pulse M is low and stable (M = M0), either the user does not like the program very much or is sleeping, and the process proceeds to S503.

  In S503, it is determined whether the user is sleeping. For example, the movement of the user's hand can be detected and determined by the acceleration sensor 207b attached to the smart watch 2b. Alternatively, information from other devices such as a camera may be combined and determined. If the result of determination is that the user is asleep, the user may have missed watching the program, and the process proceeds to S505. If the user is not sleeping (wakes up), it is determined that the program is not liked so much, and the process proceeds to S506.

In step S504, the recording unit 104 is instructed to start viewing CH recording. If recording is already in progress, recording continues.
In step S505, the recording unit 104 is instructed to start recording the viewing channel, and if recording is in progress, the recording is continued. However, when recording is started, time-shift recording is performed retroactively by a predetermined time Δt2.
In step S506, the recording unit 104 stops the recording operation. Moreover, you may delete the recorded part as needed.

In S507, the program information is referenced to determine whether or not the viewing program end time has been reached. If the end time has been reached, the process proceeds to S508 and the recording operation of the viewing program ends. If the end time has not been reached, the process returns to S501 to repeat the series of processes described above.
By executing the processing loop described above at a predetermined time interval (for example, every 1 minute), it is possible to realize a recording operation that reflects the degree of attention based on the user's pulse. In this flow, the viewing time of the same CH (program) is irrelevant. However, in the same way as in the first embodiment, the effective viewing time Δt is taken into consideration, and the recording may be started when the time Δt exceeds the predetermined time Δt1. Good.

  According to the second embodiment, it is possible to easily determine the degree of attention of the user with respect to the viewing program via the smart watch and efficiently perform automatic recording. Further, when it is determined that the user is sleeping, automatic recording is performed retroactively, so that even if the program viewing is missed, it can be reproduced and viewed later.
