Necessary. As a method of selecting a TV program to be deleted, (1) a method of selecting TV programs in order from the oldest recording time, and (2) a TV program having a lower degree of coincidence (score) with the user's preference. There is a way to choose.

FIG. 23 is a flowchart showing a flow of a method of selecting in order from the television program with the oldest recording time in the conventional automatic recording.
First, in step S2301, a TV program candidate to be automatically recorded is selected.

Next, in step S2302, it is determined whether a recording medium such as an HDD has enough free space for recording the television program selected in step S2301.
If there is any (step S2302: Y), in step S2303, the recording reservation of the television program selected in step S2301 is set.

  On the other hand, when there is no free space (step S2302: N), in step S2304, among the already recorded television programs, the oldest television program is deleted from the HDD or the like, and free space is secured in the recording medium. .

Then, the process returns to step S2302, and it is determined again whether there is free space, and the above-described processing is repeated until the free space can be secured.
FIG. 24 is a flowchart showing a flow of a method of selecting in order from a television program having a low degree of coincidence with the user's preference in conventional automatic recording.

First, in step S2401, a TV program candidate to be automatically recorded is selected.
Next, in step S2402, it is determined whether or not the recording medium such as the HDD has enough free space for recording the television program selected in step S2401.

If there is any (step S2402: Y), in step S2403, a recording reservation is set for the television program selected in step S2401.
On the other hand, if there is no free space (step S2402: N), in step S2404, the degree of coincidence (score) with the user preference of the TV program selected in step S2401 and the score of the already recorded TV program Compare with the lowest score. As a result, if the score of the television program selected in step S2401 is higher (step SS2404: Y), the television program with the lowest score among the already recorded television programs is deleted from the HDD or the like in step S2405. And free space is secured on the recording medium. Then, the process returns to step S2402, and it is determined again whether or not there is free space, and the above-described processing is repeated until free space can be secured.

On the other hand, if the score of the television program selected in step S2401 is not higher (step SS2404: N), this process ends.
In the flowcharts shown in FIGS. 23 and 24, the free space is ensured at the time of recording setting. However, only the recording setting may be performed first and the free space may be ensured before the recording is started.

When receiving a television program, the storage device 105 A “television viewing program” is loaded onto the memory 102 and the TV broadcast signal input from the TV tuner 107 is decoded. The decoded video and audio are output to an output device 104 such as a television monitor or a speaker.
Is output. In addition, the user uses the input device 103 such as a keyboard, a mouse, or a remote controller to perform setting input operations such as a TV program viewing instruction, a recording instruction, or a recording reservation instruction. In the first embodiment, a television program processing apparatus which is an information processing apparatus integrated with a television function will be described as an example. However, even a television program processing apparatus as a dedicated apparatus such as a so-called video recorder may be used. There is no difference in operation.

FIG. 2 is a diagram for explaining the basic principle of a television program processing apparatus to which the present invention is applied.
First, the television program processing apparatus 100 described with reference to FIG. 1 selects an automatic recording candidate program that matches the user's preference (S201). Here, a basic process of selecting an automatic recording candidate program that matches the user's preference will be described. Methods for extracting user preferences and selecting a favorite television program include manual setting of preference information by the user and automatic extraction by the television program processing apparatus 100. The automatic recording candidate program is generally selected from television programs that match the user's preference.

  In the manual setting, for example, there is a method of inputting a keyword, a genre, a broadcast channel, etc. relating to a favorite television program from a setting screen. Then, the television program processing apparatus 100 extracts a television program that matches the keyword, genre, and broadcast channel as a user's favorite television program based on EPG information.

  In the automatic extraction by the TV program processing apparatus 100, the TV operation history of the user such as the recording history and the EPG information are recorded in association with each other, and the TV includes the same information as the keyword and the like commonly included in the operation history. By extracting the program, the user's favorite television program is extracted.

In general, the television program selected by the manual setting or the automatic setting as described above is given a score corresponding to the degree of coincidence with the user's preference.
When the automatic recording candidate program is selected in this way, the priority order of the automatic recording candidate program and the automatically recorded program in accordance with the viewing tendency of the user is calculated (S202).

Next, an automatically recorded program and an automatically deleted program are set based on the calculated priority result (S203).
Then, an operation for the recording target program (program reserved for automatic recording, program recorded automatically) is acquired, and the history is stored in the operation history unit 201 as needed (S204). These processes (S201 to S204) are repeatedly executed, for example, once a day.

  As described above, the television program processing apparatus 100 to which the present invention is applied is viewing a television program with an emphasis on the score (the degree of coincidence with the preference) from the recorded program operation history of the user. It automatically detects whether new TV programs are valued or whether the viewers are watching in a balanced manner, and is used to select automatically recorded programs and automatically deleted programs. Then, the operation contents for the recorded program, the score, the elapsed time from the broadcast date and time to the operation time are recorded in association with each other, a weight is given to the operation contents, and the weight is added every time an operation occurs, so that the score and the broadcast The priority according to the elapsed time from the date and time can be obtained. Further, by selecting an automatically recorded program or an automatically deleted program according to the priority, automatic recording according to the viewing tendency of the user can be performed.

Thus, since the user's viewing tendency is automatically detected and the automatically recorded program and the automatically deleted program are determined, automatic recording that meets the viewing request of the user can be realized.
FIG. 3 is a functional block diagram of a television program processing apparatus to which the present invention is applied.

  In FIG. 3, a television program processing apparatus 100 includes a television program instruction input unit 301, a television program output control unit 302, a recording reservation information recording unit 303, a television program recording unit 304, a high preference television program extraction unit 305, a recording priority. A determination unit 306, a recording reservation information rewriting unit 307, a high priority television program recommendation unit 308, an electronic program guide data 309, a display device 310, a first recording medium 311, a second recording medium 312 and a priority table 313 are provided. .

  The TV program instruction input unit 301 is a viewing instruction that is an instruction for viewing a TV program at the present time, a recording instruction that is an instruction for recording a TV program at the present time, or a recording that is an instruction for recording a TV program later. Each instruction from the user, such as a reservation instruction, is input. As an instruction method, for example, an electronic program guide 309 carried by a television broadcast signal or published on the Internet is acquired, and a broadcast start time and a broadcast end time of a television program included in the electronic program guide 309 are acquired. Specify the broadcast channel.

  The television program output control unit 302 controls to output the television program specified by the viewing instruction to the display device 310 based on the viewing instruction input by the television program instruction input unit 301. The recording reservation information recording unit 303 records the recording start time, the recording end time, the broadcast channel, etc. of the TV program specified by the recording reservation instruction based on the recording reservation instruction input by the TV program instruction input unit 301. The reservation information is recorded on the first recording medium 311. The TV program recording unit 304 records the TV program specified and broadcast by the recording instruction on the second recording medium 312 based on the recording instruction input by the TV program instruction input unit 301. Further, the television program recording unit 304 specifies the broadcasted television program identified and broadcasted by the recording reservation instruction based on the recording reservation information recorded on the first recording medium 311 by the recording reservation information recording unit 303. Recording medium 312. As will be described later, the recording reservation information recorded on the first recording medium 311 may be rewritten by the recording reservation information rewriting unit 307.

  The high-preference TV program extraction unit 305 determines a user's preference level from the electronic program guide data 309 based on an operation history including a viewing instruction, a recording instruction, or a recording reservation instruction input by the TV program instruction input unit 301. Extract high-quality TV programs. For example, a television program with a high user preference is extracted using the method described above with reference to FIG. As the operation history, in addition to the viewing instruction, the recording instruction, and the recording reservation instruction described above, protection for preventing the recording reserved television program recorded in the first recording medium 311 as the recording reservation information from being deleted. Instruction, conversely, a deletion instruction for deleting a scheduled recording TV program, a viewing instruction for viewing a recorded TV program recorded on the second recording medium 312, and recording on the second recording medium 312 For example, there are a protection instruction for preventing a recorded TV program from being deleted, and a deletion instruction for deleting a recorded TV program.

  The recording priority determining unit 306 is based on the preference of the television program extracted by the high preference television program extraction unit 305 and the elapsed time from the current time of the broadcast start time or broadcast end time of the television program, The priority of the television program to be recorded on the second recording medium 312 is determined. More specifically, the recording priority determination unit 306 includes a priority table 312 in which the priority is defined in correspondence with a matrix composed of the preference level and the elapsed time as described later, for example. Prepare. The priority value defined in the priority table 312 may increase or decrease in accordance with the operation history input by the TV program instruction input unit 301. The operation input by the TV program instruction input unit 301 The magnitude of the increase / decrease may be different based on the operation contents of the history. Further, as will be described later, the amount of change over time of the priority determined by the recording priority determination unit 306, for example, the amount of change in units of one month is calculated, and the amount of change seems to be extremely large. In this case, for example, when the amount of change is equal to or greater than a predetermined value, the increase / decrease range may be increased.

  The recording reservation information rewriting unit 307 records the priority of the recording target television program extracted by the high preference television program extraction unit 305 determined by the recording priority determination unit 306 and the second recording medium 312. The recording capacity of the recorded TV program is higher than the priority of the recorded TV program, and the recording target TV program can be recorded on the second recording medium 312. If not, the recorded TV program is deleted from the second recording medium 312 and the recording target TV program is recorded on the first recording medium 311 as the recording reservation information. Alternatively, the recording reservation information rewriting unit 307 determines the priority of the recording target television program extracted by the high preference television program extraction unit 305 and the first recording medium 311 determined by the recording priority determination unit 306. Is compared with the priority level of the scheduled recording TV program included in the scheduled recording information recorded in the recording priority information, the priority level of the recording target television program is high, and the recording target television program is stored in the second recording medium 312. If there is no recording capacity that can be recorded, the recording-reserved television program is deleted from the first recording medium 311, and the recording target television program is recorded as the recording reservation information on the first recording medium 311. To do.

  In addition, the recording reservation information rewriting unit 307 does not delete the recorded television program from the second recording medium 312 or deletes the recording reserved television program from the first recording medium 311. If the recording medium 312 has no recording capacity capable of recording the recording target TV program, the recorded TV program with the next lowest priority is deleted from the second recording medium 312 or the next lowest priority The scheduled recording TV program is deleted from the first recording medium 311 and the recording target TV program is recorded in the first recording medium 311 as the recording reservation information. In this case, the TV program to be recorded can be recorded by deleting only the recorded TV program having the second lowest priority (the above-mentioned “next lowest priority”) or the reserved TV program. In such a case, only the recorded TV program having the second lowest priority may be deleted. However, if the recorded TV program cannot be recorded by this alone, the recorded TV program having the lowest priority is recorded. Delete both the recorded TV program with the second lowest priority. Of course, the same applies to the third and subsequent items.

  The high priority television program recommendation unit 308 determines the priority of the recording target television program extracted by the high preference television program extraction unit 305 and the second recording medium 312 determined by the recording priority determination unit 306. And when the priority of the recording target TV program is high, the recording target TV program is recorded on the first recording medium 311 as the recording reservation information. Recommendation to. Alternatively, the high priority television program recommendation unit 308 determines the priority of the recording target television program extracted by the high preference television program extraction unit 305 and the first recording determined by the recording priority determination unit 306. When the priority of the scheduled recording TV program included in the scheduled recording information recorded on the medium 311 is compared, and the priority of the recording target TV program is high, the recording target TV program is used as the scheduled recording information. 1 recording medium 311 is recommended.

  The electronic program guide data 309, the display device 310, the first recording medium 311, the second recording medium 312 or the priority table 313 are not included in the television program processing apparatus 100, but are provided by other external devices. And the above-mentioned functions may be realized by the television program processing apparatus 100 accessing them.

Next, a description will be given of a mechanism for automatically determining the order of high priority to be recorded from among TV programs that match the user's preference.
FIG. 4 is a diagram showing a priority table in which priorities are defined corresponding to a matrix composed of user preference levels and elapsed times.

  The example of the priority table 313 shown in FIG. 4 shows the user's preference levels shown in three stages of “score 3”, “score 2”, and “score 1”, “7 days ago”, “3 days ago”, “today ”,“ 3 days later ”,“ 7 days later ”, and a matrix format with elapsed time shown in five stages. The user's preference level indicates the preference level of the television program extracted by the high preference level television program extraction unit 305, and “score 3” is determined to have the highest preference level. The elapsed time indicates the elapsed time from the present, and “3 days ago” indicates 3 days before the present (today). The priority is shown in parentheses. For example, the priority of the preference level “score 3” elapsed time “7 days ago” is “60”. As will be described later, this priority increases or decreases based on an operation history performed on a television program to be recorded, but an appropriate value is given in advance as a default value. The TV program to be recorded is presented to the user on the reservation list screen when the recording reservation is set, and when the recording is completed, the program content is presented on the recorded TV program list screen. The

  The operation history performed on the TV program to be recorded includes (1) watching operation of the automatically recorded TV program, (2) protection operation for preventing the automatically recorded TV program from being automatically deleted, (3 ) Delete operation of automatically recorded TV program, (4) Protect operation of TV program reserved for automatic recording (operation to switch to manual recording so as not to be deleted from the recording reservation list), (5) Delete TV program reserved for automatic recording Operation is assumed. When each of the operations (1), (2), and (4) occurs, it is an operation that suits the user's preference. Therefore, a score of +1 is given to the priority value, and (3), ( When each operation of 5) occurs, since it is an operation that does not meet the preference for the user, a score of −1 is given to the priority value. Thus, each time each operation occurs, the priority is increased or decreased by adding the score to the priority of each matrix area shown in FIG. Further, the priority order of the matrix areas is determined according to the priority value of each matrix area. For example, in the example shown in FIG. 4, the preference level “score 3” elapsed time “today”, which is an underlined matrix area indicating the priority level “150”, has the priority “1”. .

Next, processing for determining a television program to be recorded or deleted based on the priority or priority determined as described above will be described.
FIG. 5 is a diagram illustrating an example of a list of candidate television programs to be recorded, and FIG. 6 is a diagram illustrating an example of a list of recorded television programs.

  The list shown in FIG. 5 is a list of television programs extracted by the high preference television program extraction unit 305 as television programs with a high user preference. The list shown in FIG. 6 is a list of TV programs included in the recording reservation information set for recording reservation based on the recording reservation instruction of the user or the recording reservation information rewritten by the recording reservation information rewriting unit 307. is there. These lists are given “preference”, “elapsed time”, and “priority” based on the priority table shown in FIG. 4, and are sorted in descending order of the “priority”. For example, a television program whose “program name” is “program A”, “program B”, “program C”, and “program D” is extracted as a television program with a high user preference by the high preference television program extraction unit 305. If so, the priority table in FIG. 4 is referred to. Since “program name” is “program A” and “preference” is “score 1” and “elapsed time” is “today”, “priority” is “8”.

  Then, when there is no free space in the storage capacity of the second recording medium 312 for recording the TV program, some TV programs are deleted from the TV programs shown in FIG. 6, and the TV shown in FIG. Recording reservations for several television programs are set from the programs.

FIG. 7 is a flowchart showing the flow of the automatic recording reservation process.
First, in step S701, a TV program having the highest “priority” is selected from among the TV programs that are candidates for automatic recording. In step S702, the TV program that has been recorded on the second recording medium 312 is selected. Among them, the TV program having the lowest “priority” is selected. In step S703, the "priority order" of the highest television program of the selected automatic recording candidate is compared with the "priority order" of the lowest television program that has been automatically recorded.

  If the “priority” of the automatic recording candidate television program is not higher than the “priority” of the automatically recorded television program (step S703: No), the processing ends. On the other hand, if the “priority” of the automatic recording candidate TV program is higher than the “priority” of the automatically recorded television program (step S703: Yes), the automatically recorded television program is selected in step S704. The program is deleted from the recorded second recording medium 312, and in step S705, a TV program that is a candidate for automatic recording is reserved and set.

  Then, in step S706, it is determined whether or not it is the last candidate TV program in the list in the order of "priority" among the automatic recording candidate TV programs. If it is the last (step S706: Yes), the processing is performed. Exit. On the other hand, if it is not the last (step S706: No), in step S707, the next highest priority TV program is selected from among the automatic recording candidate TV programs. In step S708, the second recording is performed. Among the automatically recorded television programs recorded on the medium 312, the television program having the next lower “priority” is selected, and the steps after step S 703 are repeated.

FIG. 8 is a diagram showing a priority table after execution of the automatic recording reservation process.
When the process shown in FIG. 7 is executed on the automatic recording candidate TV program shown in FIG. 5 and the automatically recorded TV program shown in FIG. 6, the second recording medium 312 is shown in FIG. The TV programs “program G” and “program H” recorded in the above are deleted, and the TV programs “program B” and “program C” are reserved. In the case of using a conventional technique that prioritizes a TV program having a high “preference”, “program E” and “program G” are deleted, and TV programs “program EC” and “program D” are reserved. End up. Moreover, in the above example, it is assumed that two programs are replaced. However, in practice, it is not possible to determine how many programs should be replaced. In the present invention, it is possible to automatically determine which television program is to be deleted and which television program is to be recorded based on the viewing tendency of the user.

FIG. 9 is a diagram illustrating an example of weights added to priority values.
As described with reference to FIG. 4, the operation content is classified into an operation that suits the preference or an operation that does not match the preference, an operation that suits the preference has a score of “+1”, and an operation that does not match the preference is “−1”. Although the score is added to the priority, in order to manage the relationship between the operation content and the preference more precisely, as shown in FIG. 9, the priority is more accurately managed by specifying the weight according to the operation content. can do.

  The above description has been made on the assumption that an appropriate priority table is given as a default value in advance. However, when the use of the television program processing apparatus or the television program processing program to which the present invention is applied is started, an operation history is stored. There is a possibility that the priority determination function cannot be used because it is not accumulated. Therefore, it is possible to set the degree of coincidence with the user's preference or the priority regarding the elapsed time from the broadcast date and time according to the user's instruction.

FIG. 10 is a diagram illustrating an example in which priority is given to the degree of match with preference or the elapsed time from the broadcast date and time, and FIG. 11 is a diagram illustrating an example of a set priority table.
For example, on the screen as shown in FIG. 10, the user uses the instruction cursor 1001 to instruct which priority is given to the degree of coincidence with the user's preference or the elapsed time from the broadcast date and time. In the example shown in FIG. 10, the degree of coincidence with the user's preference is instructed to have priority over the elapsed time from the broadcast date and time. Based on such an instruction, operation events can be added as shown in FIG. 11 to determine the priority. When processing is started using the values in the priority table, the priority can be changed little by little according to the viewing tendency of the user. In addition, when the use of this process is started, the use should be started based on a value set in advance by the provider of the TV program processing apparatus or the TV program processing program to which the present invention is applied even if there is no instruction from the user. Is also possible.

  However, when the television program processing apparatus or the television program processing program to which the present invention is applied is used for a long time, the viewing tendency may change. Since the event addition values shown in FIG. 4 are cumulatively added after the start of use, even if the viewing tendency changes after a long period of time, it takes time for the change to be reflected in the priority order.

FIG. 12 is a diagram for explaining detection of a change in viewing tendency.
As shown in FIG. 12, the priority order is managed for a predetermined period, for example, every month, and the change amount of the viewing tendency can be obtained by calculating the sum of the difference in priority order with respect to the previous period. it can. In the example shown in FIG. 12, it can be seen that the trend does not change at all from January to February in a certain year, changes slightly from February to March, and changes significantly from March to April. Therefore, when the amount of change exceeds a certain value, the change in the viewing tendency is reflected by adding the score of the latest period, for example, by multiplying several times, or by not adding the score of the month that is too old Automatic recording is possible.

  As described above, in the method for determining the TV program to be reserved for automatic recording and the TV program to be automatically deleted described with reference to FIGS. 5, 6, and 7, it is assumed that the broadcast time (the length of the program) of each TV program is constant. Explained. However, there is no problem if the sum of the broadcast time of the TV program to be deleted and the free time (available time for recording) is longer than the broadcast time of the TV program reserved for automatic recording, but the broadcast time of the TV program to be deleted If the sum of the free time is shorter, it is necessary to delete the next TV program.

An example for solving this will be described as a second embodiment with reference to FIG. 13, FIG. 14, and FIG.
FIG. 13 is a diagram showing an example of a list of candidate TV programs to be recorded in the second embodiment, and FIG. 14 is a list of recorded TV programs in the second embodiment. FIG. 15 is a flowchart showing the flow of automatic recording reservation processing in the second embodiment.

FIGS. 13 and 14 are obtained by adding broadcast times to FIGS. 5 and 6, respectively, and FIG. 15 is a processing flow of automatic recording reservation in consideration of the broadcast times.
Only parts different from the flow shown in FIG. 7 will be described with reference to FIG.

  That is, in step S703, as a result of comparing the highest television program of the automatic recording candidate with the lowest television program that has been automatically recorded, the “priority” of the automatic recording candidate of the television program has been automatically recorded. If it is higher than the “priority” of the program (step S703: Yes), in step S1501, the “broadcast time” of the highest television program of the selected automatic recording candidate and the lowest television that has been automatically recorded are selected. Compare with the “broadcast time” of the program.

If the “broadcasting time” of the automatic recording candidate television program is not shorter than the “broadcasting time” of the automatically recorded television program (step S1501: No), the process proceeds to step S708, and the second recording medium Among the automatically recorded television programs recorded in 312, the television program having the next lower “priority” is selected, and the steps after step S 703 are repeated. On the other hand, if the “broadcast time” of the automatic recording candidate TV program is shorter than the “broadcast time” of the automatically recorded television program (step S1501: Yes), the automatic recording candidate television program is selected in step S1502. A second recording medium 31 that records an automatically recorded television program for a capacity that can be recorded.
2, and in step S <b> 705, the automatic recording candidate TV program is reserved and set.

  For example, if there is no free space in the second recording medium 312, the automatic recording reservation for the TV program “Program B” having the highest “priority” for 2 hours of broadcast time is more effective than “Program B”. The TV programs “program G” and “program H” having a low “priority” are deleted to secure two hours of broadcast time. Next, in order to automatically record the TV program “program C” having a one-hour broadcast time, the 30-minute free time remaining in the previous process and “program E” having a lower priority than “program C” To secure 1 hour of broadcast time.

  In the first and second embodiments described above, the selection of the TV program to be automatically recorded and deleted has been determined based on the priority. However, in the program recommendation function that prompts the user to view and set the TV program. The program recommendation according to the viewing tendency of the user can be performed by the same principle.

Hereinafter, a television program processing apparatus and a television program processing program for recommending a television program will be described as a third embodiment to which the present invention is applied.
FIG. 16 is a diagram illustrating an example in which a user's viewing tendency is extracted from manual recording reservation and manual viewing reservation.

  The difference between the example shown in FIG. 16 and the automatic recording shown in FIG. 4 is that the operation content to be acquired is (1) manual recording reservation or (2) manual viewing reservation, and a broadcast scheduled (future) TV. It is an operation for the program.

  Basically, as in the first and second embodiments, each operation history is acquired and the priority is determined. Then, based on the determined priority, the priority order of the recommended TV program among the TV programs scheduled to be broadcast is determined.

FIG. 17 is a diagram illustrating an example of a recommended television program.
As shown in FIG. 17, the recommended TV programs are presented to the user in a list format, and are displayed in order by using a part of the TV screen being viewed. May be.

FIG. 18 is a diagram illustrating an example in which a weight is designated according to the operation content.
Similarly to the method of designating weights according to the contents of the operation history related to automatic recording described with reference to FIG. 9, the weights can be designated according to the contents of operations as shown in FIG.

  In addition, since the operation history is not accumulated at the start of use of the television program processing apparatus or television program processing program applied to the television program recommendation function, the priority determination function cannot be used. Therefore, as in the case of automatic recording, the user's instruction as shown in FIG. 10 can set the degree of coincidence with the preference and the priority regarding the time until the broadcast date (new program).

FIG. 19 is a diagram illustrating an example in which the initial priority is determined by the user's designation in the third embodiment.
The example shown in FIG. 19 is an example in which the user prioritizes the degree of coincidence with the preference and the time until the start of broadcasting at the same ratio.

It should be noted that the television program processing device or the television program processing program to which the present invention is applied can be used even when the use of the television program processing device or the television program processing program applied to the television program recommendation function is started or without the user's instruction. It is also possible to start use based on a value preset by the provider.

However, even when a TV program processing apparatus or a TV program processing program applied to the TV program recommendation function is used for a long time, the viewing tendency may change.
FIG. 20 is a diagram illustrating an example of a change in viewing tendency according to the third embodiment.

  Therefore, as shown in FIG. 20, it is possible to obtain the amount of change in viewing tendency and perform adjustment according to the change in the same manner as in FIG. 12 shown in the example of automatic recording. In the example shown in FIG. 20, it can be seen that the trend does not change at all from January to February in a certain year, changes slightly from February to March, and changes significantly from March to April. Therefore, when the amount of change exceeds a certain value, the change in the viewing tendency is reflected by adding the score of the latest period, for example, by multiplying several times, or by not adding the score of the month that is too old Program recommendation is possible.
