Also good.

  The control unit 24 is configured to control each component of the recording device 100.

  Next, with reference to FIGS. 2 to 4, control by the control unit 24 relating to a function of reserving a broadcast program broadcast as the next round of a predetermined broadcast program will be described. The operation by the user is performed using the operation unit 19.

  First, as shown in FIG. 2, when a predetermined broadcast program in the electronic program guide displayed on the display unit 18 is reserved by the user, the control unit 24 selects a predetermined broadcast program that has been reserved. It is configured to perform control for acquiring program information. As shown in FIG. 2, the program information of the predetermined broadcast program includes information on the channel on which the predetermined broadcast program is broadcast (4CH), information on the broadcast start time of the predetermined broadcast program (Tuesday, March 18, 2014) 21:00), information on the broadcast end time of the predetermined broadcast program (Tuesday, March 18, 2014, 22:00), and the program name of the predetermined broadcast program ("Aikata") are included.

  In addition, the control unit 24 reserves a broadcast program to be broadcast as the next round of the predetermined broadcast program from the electronic program table based on the acquired program name of the predetermined broadcast program ("Companion" in FIG. 2). Therefore, it is configured to perform control for searching for and detecting as the next reserved program.

  Specifically, first, the control unit 24 sets the degree of coincidence between the acquired program name of the predetermined broadcast program and the program name of the broadcast program to be searched for the next reserved program in the electronic program guide to a predetermined algorithm. It is comprised so that the control acquired based on may be performed. As a broadcast program to be searched, for example, when a broadcast program that is broadcast every week is continuously reserved, it is the day after one week of the predetermined broadcast program and the time at which the predetermined broadcast program is broadcast. It is possible to set a broadcast program included in the same channel as the predetermined broadcast program is broadcast for one hour before and after. In this case, in the example of the predetermined broadcast program shown in FIG. 2, “broadcast program broadcast on 4CH between 20:00 to 23:00 on Tuesday, March 25, 2014” is the search target of the next reserved program. Set as a broadcast program.

  Then, the control unit 24 determines whether or not the degree of coincidence acquired based on a predetermined algorithm in each of the search target broadcast programs is larger than a threshold value for determining whether or not it is a next reserved program. In the case where it is larger than the threshold value, the broadcast program to be searched is controlled to be detected as the next reserved program. If the degree of coincidence acquired is equal to or less than the threshold value, the search target broadcast program is not detected as the next reserved program.

  Here, as shown in FIG. 3, in relation to a special program that is broadcast over a long period of time such as 24 hours (55 hours in FIG. 3), the program name of the broadcast program broadcast every week or every day is written. A column may be added. In FIG. 3, a character string “55 hours television” is added to a program name that is originally “mother” in relation to a special program or the like. In this case, the degree of coincidence between the program name of the predetermined broadcast program (“Aikata”) and the program name of the broadcast program with the character string added (“55 hours TV companion”) decreases. A broadcast program that is supposed to be detected as the next reserved program may not be detected as the next reserved program.

Therefore, in the first embodiment, the control unit 24 performs control for searching for and acquiring a common character string other than the program name of a predetermined broadcast program from the program names of a plurality of broadcast programs in the electronic program guide. When the character string is acquired, the next reserved program is searched with the acquired common character string excluded from at least the program name of the broadcast program to be searched for the next reserved program (state in FIG. 4). Configured to detect. Thereby, it is possible to detect the next reserved program in a state in which the character string added to the program name of the broadcast program in relation to the special program is excluded.

Further, in the first embodiment, when the control unit 24 searches for and acquires a common character string, the control unit 24 sets each broadcast program included in the electronic program guide as one broadcast program next time. The program name of one broadcast program broadcast in the time zone corresponding to the broadcast program to be searched for the reserved program, and other broadcast programs broadcast continuously before and after the time when the one broadcast program is broadcast It is configured to search for and acquire a common character string other than the program name of a predetermined broadcast program from the program names of a plurality of broadcast programs in the electronic program guide consisting of the program names of the program names.

Next, an example of control for acquiring a common character string will be described with reference to FIG. Here, an example in which a predetermined broadcast program shown in FIG. 2 is reserved is described.

  For example, as shown in FIG. 3, when “55 hours TV companion” started broadcasting from 21:00 is one broadcast program, the time before and after the time when “55 hours TV companion” is broadcasted. “Δ Day Suspense” and “55 Hour Television The News” broadcast continuously are other broadcast programs. In addition, as other broadcast programs broadcast before and after the time, not only the broadcast program broadcast just before or just after the time when one broadcast program is broadcast, but before the broadcast program broadcast immediately before, or A broadcast program subsequent to the broadcast program broadcast immediately after may be included.

In this case, a common character string other than the program name of the predetermined broadcast program (“companion”) is searched from “55-hour television companion”, “Δ day suspense”, and “55-hour television THE news”. That is, “55 hours television” from “55 hours television partner” is extracted as a character string other than the program name of a predetermined broadcast program. Since “55 hours television” is included in “55 hours television the news”, “55 hours television” is acquired as a common character string other than the program name of a predetermined broadcast program. If there is no common character string other than the program name of the predetermined broadcast program, the excluded character string is not acquired. In the recording apparatus 100, such control for acquiring the character string to be excluded is executed for each of all broadcast programs included in the electronic program guide.

Next, an example of control for searching for and detecting the next reserved program in a state where the acquired common character string is excluded will be described with reference to FIGS. 3 and 4. Here, the predetermined broadcast program shown in FIG. 2 is reserved, and “the broadcast program broadcast on 4CH between Tuesday, March 25, 2014, 20:00 to 23:00” is the next reserved program. An example set as a broadcast program to be searched will be described. Further, the degree of coincidence is converted into any value in the range of 0 to 200 based on a predetermined algorithm. Note that the higher the numerical value, the greater the degree of matching. Further, the threshold value for determining whether or not it is the next reserved program is set to 60.

FIG. 3 shows a state before the acquired common character string is excluded in “a broadcast program broadcast on 4CH between Tuesday, March 25, 2014, 19:00 to 24:00”. Therefore, “Δ Day Suspense Theater”, “55 Hours Television Partner”, and “55 Hours Television The News” are broadcast programs to be searched for the next reserved program.

In a state where the acquired common character string is not excluded, the degree of coincidence between the program names of these broadcast programs and the program name of the predetermined broadcast program (“companion”) is based on a predetermined algorithm. 24. In this case, since “Δ Day Suspense Theater” and “55 Hour Television The News” do not include a character string in common with “Aikata”, the degree of coincidence is zero. In addition, the degree of coincidence based on a predetermined algorithm between the “companion” and the “55-hour television companion” is 28. Accordingly, since the degree of matching (28) acquired is equal to or less than the threshold value (60), in the state where the acquired common character string is not excluded, “55 hours that should be originally detected as the next reserved program” “TV partner” is not detected as the next reserved program.

On the other hand, in FIG. 4, the acquired common character string (“55 hours TV”) is excluded from “broadcast program broadcast on 4CH between 19: 00 to 24:00 on Tuesday, March 25, 2014”. The later state is shown. Therefore, “Δ Day Suspense Theater”, “Companion”, and “THE News” are broadcast programs to be searched for the next reserved program.

Then, the degree of coincidence of the program names of these broadcast programs with the program name of the predetermined broadcast program (“mother”) is acquired by the control unit 24 based on a predetermined algorithm. Also in this case, since “Δ Day Suspense Theater” and “THE NEWS” do not include a character string that is common to “COMPONENT”, the degree of coincidence is zero.

In addition, the degree of coincidence based on a predetermined algorithm between “akata” as a program name of a predetermined broadcast program and “akata” as a program name of a broadcast program to be searched for the next reserved program is 200 (maximum value). It is. Therefore, since the degree of coincidence (200) obtained is greater than the threshold (60), the broadcast whose original program name was “55 hours TV companion” when the obtained common character string is excluded. The program can be detected as the next reserved program. The numerical values described above are merely examples, and the present invention is not limited to these.

  Next, the next reserved program search process in the recording apparatus 100 will be described with reference to the flowchart with reference to FIG.

First, as shown in FIG. 5, in step S1, control for searching for a common character string from each of all broadcast programs included in the electronic program guide is performed by the control unit 24 (see FIG. 1). Specifically, control for searching for a common character string other than the program name of a predetermined broadcast program is performed by the control unit 24 for each of all broadcast programs included in the electronic program guide.

In step S2, the control unit 24 performs control for determining whether there is a common character string. That is, the control unit 24 performs control for determining whether or not a common character string other than the program name of the predetermined broadcast program is found in each of all broadcast programs included in the electronic program guide. If it is determined that the character string has not been found, the process proceeds to step S5 without acquiring the character string to be excluded. If it is determined that it has been found, the process proceeds to step S3.

In step S <b> 3, control for acquiring a common character string is performed by the control unit 24. Specifically, the control unit 24 performs control to acquire a common character string other than the program name of a predetermined broadcast program found in all broadcast programs included in the electronic program guide.

In step S4, the control unit 24 performs control to exclude the acquired common character string from each of all broadcast programs included in the electronic program guide. Specifically, if one common character string is acquired, to exclude one common character string, in a case where a plurality of common character string is acquired, a plurality of common character string The control to be excluded is performed by the control unit 24. As a result, the electronic program guide is in a state in which the acquired common character string is excluded from the program names of broadcast programs to be searched for the next reserved program.

  In step S5, the control unit 24 performs control for searching for the next reserved program. Specifically, the control unit 24 controls the search for the next reserved program based on the degree of coincidence between the program name of the predetermined broadcast program and the program name of the broadcast program to be searched for the next reserved program in the electronic program guide. Is done.

  In step S6, the control unit 24 performs control for determining whether or not a next reserved program is detected. That is, the control unit 24 performs control for determining whether or not a program having a degree of coincidence greater than a threshold value has been found. If a program with a matching degree greater than the threshold is found, the process proceeds to step S7. On the other hand, if no program having a matching degree greater than the threshold value is found, the process proceeds to step S8.

  When the next reserved program is detected, control for presenting the detected next reserved program is performed by the control unit 24 in step S7. Specifically, the control unit 24 performs control to display the detected next reserved program on the display unit 18 (see FIG. 1). Then, the next reserved program search process in the recording apparatus 100 is ended.

  If the next reserved program is not detected, the control unit 24 performs control indicating that the next reserved program is not detected in step S8. Specifically, the control unit 24 controls the display unit 18 to display that the next reserved program is not detected. Then, the next reserved program search process in the recording apparatus 100 is ended.

  In the first embodiment, the following effects can be obtained.

In the first embodiment, as described above, the control unit 24 is configured to perform control for acquiring a common character string from the program names of a plurality of broadcast programs in the electronic program guide, so that a normal special program, etc. A character string (for example, “55 hours television”) added to the program name in relation to the program name is added as a common character string common to the program names of a plurality of broadcast programs. It can be acquired as a character string excluding the character string added to the program name in relation. Then, by excluding the acquired common character string, the control unit 24 is configured to perform control for detecting the next reserved program, whereby a character string ( That is, the next reserved program can be detected in a state where the acquired common character string) is excluded. As a result, the next reserved program can be detected even when a character string is added to the program name in relation to a special program.

In the first embodiment, as described above, the program name of one broadcast program in the electronic program guide and other broadcasts continuously broadcast before and after the time when the one broadcast program is broadcast. The control unit 24 is configured to perform control for acquiring a common character string from the program names of a plurality of broadcast programs in the electronic program guide including the program name of the program. As a result, a character string added to a program name related to a special program or the like is added to program names of a plurality of broadcast programs that are broadcast continuously in time, so that a special program or the like can be obtained. The character string added to the program name in relation can be easily obtained.

In the first embodiment, as described above, the program name of one broadcast program broadcast in the time slot corresponding to the broadcast time of the broadcast program to be searched for the next reserved program and the one broadcast program are as follows. Control to acquire a common character string from the program names of a plurality of broadcast programs in the electronic program guide consisting of program names of other broadcast programs broadcast continuously before and after the broadcast time. The control unit 24 is configured as follows. As a result, a common character string can be acquired from a broadcast program in a time zone in which there is a high possibility that the next reserved program exists, and broadcast programs before and after the broadcast program, so that the next reserved program can be detected more effectively. it can.

In the first embodiment, as described above, when a common character string is acquired, each of all broadcast programs included in the electronic program guide is acquired as a single broadcast program, and the common character string is acquired. The control unit 24 is configured to perform control.

  The remaining effects of the third embodiment are similar to those of the aforementioned first embodiment.

(Fourth embodiment)
Next, a fourth embodiment will be described with reference to FIGS. 1 and 8. In the fourth embodiment, unlike the first and third embodiments, control for detecting a next reserved program is performed in a state where control for acquiring a common character string is not performed, and the next reserved program is not detected. Next, an example of performing control for acquiring a common character string will be described.

As shown in FIG. 1, the recording apparatus 400 according to the fourth embodiment of the present invention searches for a next reserved program without performing control for acquiring a common character string other than the program name of a predetermined broadcast program. A control unit 324 that performs control to detect and performs control to acquire a common character string when the next reserved program is not detected is provided. In addition, about the same structure as the said 1st-3rd embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  As in the first embodiment, the control unit 324 determines whether the degree of matching of the program name with the program name of the predetermined broadcast program acquired based on the predetermined algorithm is the next reserved program. It is determined whether or not the broadcast program is larger than the threshold value, and when it is larger than the threshold value, the broadcast program is controlled to be detected as the next reserved program.

Here, in the fourth embodiment, the control unit 324 performs control for searching for and detecting the next reserved program without performing control for acquiring a common character string other than the program name of the predetermined broadcast program. It is configured. Further, the control unit 324 broadcasts a program having a program name partially including a program name of a predetermined broadcast program when the next reserved program is not detected (when the degree of matching acquired is equal to or less than a threshold value). When a program is detected (for example, the program name of a predetermined broadcast program is “Aikata”, and “55 hours TV companion” is detected as a broadcast program having a program name partially including the program name of the predetermined broadcast program) In a state where a common character string other than the program name of the predetermined broadcast program is acquired, and the acquired common character string is excluded from the program name of the broadcast program to be searched for the next reserved program, Control is performed to search and detect the next reserved program.

In addition, when a broadcast program having a program name partially including the program name of the predetermined broadcast program is detected, the control unit 324 has a broadcast program having a program name partially including the program name of the predetermined broadcast program. Is set as one broadcast program, the program name of one broadcast program broadcast in the time zone corresponding to the broadcast program to be searched for the next reserved program, and the time before and after the time when the one broadcast program is broadcast Control to acquire a common character string other than the program name of a predetermined broadcast program from the program names of a plurality of broadcast programs in the electronic program guide consisting of program names of other broadcast programs broadcast continuously in time Configured to do.

  Next, referring to FIG. 8, the next reserved program search process in the recording apparatus 400 will be described based on a flowchart.

First, as shown in FIG. 8, in step S11, control for searching for the next reserved program is performed by the control unit 324 (see FIG. 1). Specifically, in a state where control for acquiring a common character string other than the program name of the predetermined broadcast program is not performed, the program name of the predetermined broadcast program and the broadcast program to be searched for the next reserved program in the electronic program guide Based on the degree of coincidence with the program name, the control unit 324 performs control to search for the next reserved program.

  In step S12, the control unit 324 determines whether or not the next reserved program is detected. In other words, the control unit 324 determines whether or not a program having a degree of matching greater than a threshold value has been found. If a program having a matching degree greater than the threshold is found, the process proceeds to step S20. On the other hand, if no program having a matching degree greater than the threshold value is found, the process proceeds to step S13.

  In step S13, the control unit 324 determines whether there is a broadcast program having a program name including a part of the program name of the predetermined broadcast program. If it is determined that there is no broadcast program having a program name including a part of the program name of the predetermined broadcast program, the next reserved program is not detected, and the process proceeds to step S21. If it is determined that there is a broadcast program having a program name including a part of the program name of the predetermined broadcast program, there is a possibility that the character string to be excluded is included, and the process proceeds to step S14.

In step S14, the control unit 324 performs control for searching for a common character string from broadcast programs having a program name including a part of the program name of a predetermined broadcast program. Specifically, control for searching for a common character string other than the program name of the predetermined broadcast program is controlled for each of one or a plurality of broadcast programs having a program name partially including the program name of the predetermined broadcast program. Performed by the unit 324.

In step S15, the control unit 324 determines whether there is a common character string. That is, control for determining whether or not a common character string other than the program name of the predetermined broadcast program is found in each of one or a plurality of broadcast programs having a program name partially including the program name of the predetermined broadcast program Is performed by the control unit 324. If it is determined that the character string has not been found, the process proceeds to step S21 without acquiring the character string. If it is determined that it has been found, the process proceeds to step S16.

In step S <b> 16, the control unit 324 performs control for acquiring a common character string. Specifically, control for acquiring a common character string other than the program name of the predetermined broadcast program found in each of one or a plurality of broadcast programs having a program name partially including the program name of the predetermined broadcast program is performed. This is performed by the control unit 324.

In step S17, the control unit 324 performs control to exclude a common character string from each of all broadcast programs included in the electronic program guide. Specifically, if one common character string is acquired, to exclude one common character string, in a case where a plurality of common character string is acquired, a plurality of common character string The control to be excluded is performed by the control unit 324. As a result, the electronic program guide is in a state in which the acquired common character string is excluded from the program names of broadcast programs to be searched for the next reserved program.

In step S18, the control unit 324 performs control to re-search for the next reserved program. Specifically, separately from step S11, a control for searching for and detecting the next reserved program in a state where the common character string acquired in step S16 is excluded from the program names of broadcast programs to be searched for the next reserved program. Is again performed by the control unit 324.

In step S19, separately from step S12, control for determining whether or not the next reserved program is detected is performed again by the control unit 324. In other words, the control unit 324 determines whether or not a program having a degree of matching greater than a threshold value has been found. If a program whose degree of matching is greater than the threshold is found, it is considered that the next reserved program has been detected by excluding the acquired common character string, and the process proceeds to step S20. If no program having a matching degree greater than the threshold value is found, it is considered that the next reserved program is not detected even if the acquired common character string is excluded, and the process proceeds to step S21.

  When the next reserved program is detected, the control unit 324 performs control to present the detected next reserved program in step S20. Specifically, the control unit 324 controls the display unit 18 to display the next reserved program detected in the process of step S12 or the process of step S19. Then, the next reserved program search process in the recording apparatus 400 is ended.

  If the next reserved program is not detected, the control unit 324 performs control indicating that the next reserved program is not detected in step S21. Specifically, the control unit 324 controls to display on the display unit 18 (see FIG. 1) that the next reserved program is not detected. Then, the next reserved program search process in the recording apparatus 400 is ended.

  The remaining configuration of the fourth embodiment is similar to that of the aforementioned third embodiment.

  In the fourth embodiment, the following effects can be obtained.

In the fourth embodiment, by configuring the control unit 324 to perform control for acquiring a common character string from program names of a plurality of broadcast programs in the electronic program guide, as in the first embodiment, The next reserved program can also be detected when a character string is added to the program name in relation to a special program.

Further, in the fourth embodiment, as described above, control is performed to search for and detect a broadcast program having a program name partially including the program name of the predetermined broadcast program, and the program name of the predetermined broadcast program is determined. When a broadcast program having a program name included in a part is detected, a common character string is acquired using the broadcast program having a program name including a part of the program name of the predetermined broadcast program as one broadcast program. The control unit 324 is configured as described above. Accordingly, it is highly possible that the broadcast program having a program name including a part of the program name of the predetermined broadcast program is a broadcast program that is highly likely to be the next reserved program. When a broadcast program is detected, a common character string other than the program name of the predetermined broadcast program is acquired from the program name of the broadcast program that is likely to be the next reserved program and the program name of the corresponding other broadcast program. Can do. As a result, it is possible to reduce the processing load related to the process of acquiring the common character string by acquiring only a part of the electronic program guide as the detection target while acquiring the common character string more effectively.

Further, in the fourth embodiment, as described above, the next reserved program is performed based on the program name of the predetermined broadcast program without performing control for acquiring a common character string other than the program name of the predetermined broadcast program. performs control for detecting, when the next reserved program is not detected, it performs control to acquire the common strings, while excluding the common character string acquired, performs control to detect the next reserved program The control unit 324 is configured as described above. Thus, when the next scheduled program without excluding the common character string is detected, the control to get a common string is not performed, in this case, the control to get a common string Can reduce the processing load. On the other hand, when the next reserved program is not detected, a common character string can be acquired by performing control to acquire a common character string, so that the next reserved program can be detected.

  The remaining effects of the fourth embodiment are similar to those of the aforementioned third embodiment.
