Description

  The present invention relates to a recording apparatus, an information processing method, a recording medium, and a program, and more particularly, to a recording apparatus, an information processing method, a recording medium, and a program that can record a program that seems to be a user's preference more efficiently.

  2. Description of the Related Art In recent years, recording apparatuses that search for a program that is considered to be a user's preference (a program broadcast on television) based on a keyword set (input) by a user and record the searched program have become widespread.

  This recording device searches for a program that seems to be a user's preference from electronic information (electronic program information) indicating a broadcast schedule of a program, corresponding to a radio / TV column of a so-called newspaper, based on a keyword. Schedule recording for. The recording device receives the program reserved for recording, and records the received program.

  By the way, in the conventional recording apparatus, there are restrictions by hardware and software, and the number of recording reservations is determined in advance. Therefore, the recording apparatus needs to select a program to be recorded from the searched programs so as not to exceed a predetermined number of recording reservations that can be reserved. There are restrictions. In other words, the recording apparatus can make a recording reservation only for a predetermined number of programs among the programs broadcast on a day.

  For example, in the case where 80 programs to be recorded are selected from programs broadcasted for 8 days on the basis of the day when recording is reserved, the recording apparatus records the selected program as shown in FIG. Depending on the day, the number of programs that can be scheduled to be recorded for the program broadcast on that day (hereinafter also referred to as the maximum number of programs that can be reserved) is predetermined.

  That is, in the recording apparatus, a total of 80 recordings can be reserved during the 8 days from the first day to the eighth day. In addition, recording of up to 80 programs can be reserved on the first and second days respectively, and recording of up to seven programs can be reserved on the third to eighth days. can do.

  At this time, the recording device searches for a program that seems to be a user's preference based on the keyword, and reserves recording of the searched program in order from the first day.

  Therefore, if 80 programs are searched on the first day as a result of searching for a program that seems to be a user's preference based on the keyword, the recording device selects the searched 80 programs and selects the first day. Schedule recording of 80 programs. At this time, from the second day to the eighth day, even if a program that seems to be a user's preference is searched, it will exceed 80, which is a predetermined number of recordings that can be reserved, The recording device does not reserve recording of the searched program.

  In addition, as a conventional recording apparatus, there is a recording apparatus that reserves recording of a program based on preference information designated by a user (see, for example, Patent Document 1). In this recording apparatus, preference information designated by the user transmitted from the server is received, and a program recording reservation is executed based on the received preference information.

JP 2004-80620 A

  However, in the above-described technique, the possibility that a program will be recorded becomes lower as the date after the reference date is based on the date when recording is reserved, so that programs of various genres can be recorded. As a result, there is a problem in that the types of program genres that can be provided to the user are reduced, and the merchantability of the recording apparatus is lowered.

  Moreover, since the possibility that a program will be recorded becomes lower as the date after the reference date (the far day) is based on the date on which the recording is reserved, the user will not be able to record on the date close to the reference date. Even a program that is not so popular is recorded, and on a day far from the reference date, there is a problem that a program that the user seems to prefer more than the recorded program is not recorded.

  Furthermore, the number of programs that can be reserved in one day can be limited so that a predetermined number of programs can be recorded on all the days that are searched for the programs to be recorded. Since there are fewer days than the number of programs that can be reserved per day, only a smaller number of programs can be recorded than the number that can be reserved for recording. There was a problem that it could not be used as much as possible.

  Furthermore, the number of programs that seem to be user's preference is not the same depending on the day, and even if the number of programs that are found to be the user's preference is the same depending on the day, The searched programs include programs that the user wants to watch and programs that the user does not want to watch (does not want to watch), and therefore the number of programs that the user wants to watch is not always the same depending on the day.

  Hereinafter, an embodiment to which the present invention is applied will be described with reference to the drawings.

  FIG. 2 is a diagram for explaining a program distribution system according to the present invention.

  The program distribution system includes a transmission station 11, a satellite 12, a recording device 13, and a server 14, and the recording device 13 is connected to the server 14 via a communication network 15.

  The transmission station 11 of the broadcast station emits an analog broadcast signal or a digital broadcast signal that is a terrestrial wave (radio wave), thereby program distribution information that is information indicating a broadcast schedule of a program broadcast by the transmission station 11 (broadcast station). Is sent to the recording device 13.

  Here, the program distribution information includes, for example, the title of the program to be broadcast, the broadcast date and time, the genre of the program, meta information indicating the contents of the program such as performers, and the name of the broadcast station that broadcasts the program. . The user can record the program with reference to the program distribution information in the recording device 11.

  The transmitting station 11 transmits program distribution information to the satellite 12 by radiating analog broadcast signals or digital broadcast signals that are radio waves.

  The satellite 12 receives the program distribution information transmitted from the transmitting station 11, and radiates an analog broadcast signal or a digital broadcast signal that is a radio wave (hereinafter referred to as a satellite wave), thereby receiving the received program distribution information. Immediately send to the recording device 13.

  The recording device 13 receives the program distribution information transmitted from the transmitting station 11 or the satellite 12 and holds the received program distribution information.

  The server 14 generates program distribution information, and transmits the generated program distribution information to the recording device 13 via the communication network 15.

  The recording device 13 receives the program distribution information transmitted from the server 14 and holds the received program distribution information. The recording device 13 is selected and recorded by the recording device 13 by referring to the stored program distribution information based on the setting information including the keyword input by the user, that is, the program that seems to be the user's preference. A program to be a candidate for a program (hereinafter referred to as an automatic recording candidate) is selected.

  Here, the setting information includes, for example, information indicating a keyword for selecting a program, the number of programs (contents) to be recorded, a date on which to select a program to be recorded, and the like. Set by the user. In addition, the recording device 13 can automatically select a program in which, for example, a keyword included in the setting information among the programs indicated by the program distribution information is included in the program distribution information as a word indicating the content of the program. Select as.

  Therefore, for example, when the keyword “sports” is included in the setting information, the recording device 13 selects from the program distribution information, for example, a program including the word “sports” in the meta information as an automatic recording candidate. Select as a program.

  The recording device 13 calculates the score of each program selected as an automatic recording candidate based on the preference value and meta information of the recorded content and the program distribution information. Here, the content preference value is a value indicating the degree of user preference for the content. For example, when content is reproduced, the content preference value is similar to the content and the content of the reproduced content. Will increase. The content meta-information includes information such as a word indicating the content content, a genre, and a content title.

  The score of the program selected as the automatic recording candidate indicates the degree to which the user seems to like the program. For example, the automatic recording candidate is based on the preference value and meta information of the recorded content and the program distribution information. It is calculated by adding the preference value of the content similar to the content of the program.

  The recording device 13 generates a recording reservation table based on the calculated score of a program that is a candidate for automatic recording, and holds the generated recording reservation table. Here, the recording reservation table includes, for example, the broadcast date, broadcast start time, broadcast end time, and the like of the program reserved for recording. For example, when the recording device 13 can reserve up to 80 recordings of programs, the recording device 13 reserves recordings of 80 programs in descending order of scores of programs that are automatic recording candidates.

  In this case, the recording reservation table includes information indicating that recording of a program is reserved for each reserved program. That is, the recording reservation table includes information indicating that recording of 80 programs is reserved.

  In addition, the transmission station 11 transmits a program broadcast by the transmission station 11 to the recording device 13 by radiating an analog broadcast signal or a digital broadcast signal that is a terrestrial wave. More specifically, the transmission station 11 transmits the moving image data and audio data for reproducing the program broadcast by the transmission station 11 to the recording device 13 by radiating terrestrial waves. Hereinafter, moving image data and audio data for reproducing a program are referred to as content data.

  The transmitting station 11 transmits a program broadcast by the transmitting station 11 to the satellite 12 by radiating an analog broadcast signal or a digital broadcast signal that is a radio wave. More specifically, the transmitting station 11 transmits content data of a program broadcast by the transmitting station 11 to the satellite 12 by radiating radio waves.

  The satellite 12 receives the program transmitted from the transmitting station 11 and radiates an analog broadcast signal or a digital broadcast signal that is a satellite wave, thereby immediately transmitting the received program to the recording device 13.

  The recording device 13 receives a program transmitted from the transmission station 11 or the satellite 12. The recording device 13 refers to the recording reservation table, extracts content data of the program reserved for recording from the received program, and records the program by recording the extracted content data.

  At this time, for example, the number of programs reserved for recording included in the recording reservation table held by the recording device 13 varies depending on the day. That is, since the recording device 13 reserves recording of programs in descending order of score, the number of programs recorded per day is determined by the score of programs that are automatic recording candidates.

  Therefore, for example, when the recording device 13 can reserve up to 80 recordings of a program, as shown in FIG. 3, on the first day (the recording reservation date) with reference to the recording reservation date. Are reserved for recording 10 programs. On the second day, recording of three programs is reserved, and on the third day, recording of seven programs is reserved.

  Similarly, recording of 15 programs is reserved on the 4th day, recording of 20 programs is reserved on the 5th day, and recording of 12 programs is scheduled on the 6th day. Recording is scheduled. Furthermore, recording of 8 programs is reserved on the 7th day, and recording of 15 programs is reserved on the 8th day. The total number of programs reserved for recording from the first day to the eighth day is 80.

  In addition, when the recording device 13 uses the program distribution information distributed at a predetermined time, the recording device 13 generates the recording reservation table every time the recording device 13 receives the program distribution information. Thus, by calculating the score of a program that is a candidate for automatic recording and reserving recording of the program in descending order of the calculated score, it is possible to efficiently record a program that seems to be a user's preference. Furthermore, by generating a recording reservation table each time program distribution information is received, it is possible to always select a program that the user seems to prefer in response to changes in the program distribution information. It is possible to efficiently record programs that seem to be favorite.

  In more detail, the process in which the recording device 13 generates the recording reservation table is performed every time the distributed program distribution information is updated.

For example, when the recording device 13 can reserve up to 80 recordings of programs, the automatic recording control unit 73 reserves recording of 80 programs in descending order of scores of programs that are automatic recording candidates. Reservation information is generated as follows.

  More specifically, when the recording of the program instructed by the user is reserved, the automatic recording control unit 73 determines the number of programs instructed by the user from the number of records that can be reserved by the recording device 13. Reservation information is generated so as to reserve the recording of a program that is the number of automatic recording candidates obtained by subtracting the number of recording reservations.

  Therefore, for example, the recording device 13 can reserve up to 80 recordings of a program, and the recording reservation table held in the recording reservation table holding unit 74 records 3 recordings of the program instructed by the user. When reserved, the automatic recording control unit 73 reserves recording of programs so that recording of 77 (80-3) programs is reserved in descending order of the scores of programs that are automatic recording candidates. Generate reservation information for.

  The recording reservation table holding unit 74 holds a recording reservation table. The recording reservation table holding unit 74 generates a recording reservation table based on the reservation information supplied from the manual recording control unit 72 or the automatic recording control unit 73 to reserve the recording of the program, and the generated recording reservation table Hold.

  The recording reservation table holding unit 74 supplies the held recording reservation table to the recording control unit 75. When the recording of the program ends, the recording reservation table holding unit 74 deletes the recording reservation of the program for which recording has ended from the recording reservation table under the control of the recording control unit 75. That is, the recording reservation table holding unit 74, when the recording of the program is completed, is included in the information indicating that the recording of the program is reserved included in the recording reservation table under the control of the recording control unit 75. The information indicating that the recording of the program that has been recorded is reserved is deleted.

  The recording control unit 75 refers to the recording reservation table held in the recording reservation table holding unit 74 and records the program reserved for recording. That is, the recording control unit 75 refers to the recording reservation table held in the recording reservation table holding unit 74 and acquires the content data of the program reserved for recording from the digital tuner 33 or the CODEC 34. The recording control unit 75 supplies the acquired content data to the recording unit 41 and controls the recording unit 41 to record the supplied content data. The recording control unit 75 causes the recording unit 41 to record the content data, and then controls the recording reservation table holding unit 74 to include information indicating that the program recording is reserved, which is included in the recording reservation table. Among them, the information indicating that the recording of the recorded program is reserved is deleted.

  When an input signal for erasing content data is supplied from the operation input unit 39, the recording control unit 75 controls the recording unit 41, and information indicating content data specified by the user included in the input signal Based on this, the specified content data is deleted.

  The preference value calculation unit 76 calculates the preference value of the content recorded in the recording unit 41 and supplies the calculated preference value to the recording unit 41.

  For example, when the content that is music is reproduced based on the content data recorded in the recording unit 41, the preference value calculation unit 76, the content that is the reproduced music, and the content of the reproduced content, The content preference value is calculated so that the preference value of content having similar contents increases.

  At this time, the preference value calculation process and the content determination process are performed, for example, based on the content meta information recorded in the recording unit 41 together with the content data. .

  Here, in the meta information of the program content, for example, a word indicating the content of the program including information indicating whether or not the program recording reservation is instructed by the user, the program title, the performer, and the like , The genre of the program, the channel, the number of times the content is played, the date and time when the content was last played, and the like. The meta information of the music content data includes information indicating the characteristics of the music such as the title, genre, artist name, and music tempo.

  Therefore, in this case, for example, the preference value calculation unit 76 calculates the content preference value so that the content preference value of the audio data content similar to the content of the reproduced music content increases. In this case, for example, the preference value is calculated so that the preference value of the content of a program that is a music program increases. For example, if the meta information of the reproduced music content includes information indicating that the genre of the content is “jazz”, the preference value calculation unit 76 includes the meta information of the recorded content. The content preference value is calculated so that the content preference value including the word “jazz” in the information increases.

  Further, for example, when the content data recorded in the recording unit 41 is deleted, the preference value calculation unit 76 is configured so that the preference value of the content having the content similar to the content content of the deleted content data is decreased. The content preference value is calculated.

  Furthermore, a preference value may be calculated from a preference-related prediction. For example, when content of a still image is reproduced (displayed), image analysis processing is performed on the displayed still image, and as a result, when the displayed still image is a dark-feeling still image, the preference value The calculation unit 76 calculates the content preference value so that the content preference value of the suspense program is increased, and information indicating that the music is fast-tempo is included in the meta information of the content. It is also possible to calculate the content preference value so that the preference value of the content of the sports program increases when the music content is played.

  When calculating the content preference value, a preference value may be calculated by adding a weight to information such as a word included in the meta information. In this case, for example, the preference value of the content having the same genre as the reproduced content genre is increased by 2 points, and the word indicating the reproduced content genre is added to the meta information as the word indicating the content content. The preference value of the contained content can be increased by 1 point.

  Further, the preference value calculation unit 76 may calculate the content preference value when recording of a program is reserved.

  The score calculation unit 77 is an automatic selected by the automatic recording control unit 73 based on the program distribution information supplied from the program distribution information holding unit 71 and the preference value and meta information of the content recorded in the recording unit 41. The score of a program that is a recording candidate is calculated. The score calculation unit 77 supplies the calculated score of the program that is the automatic recording candidate to the automatic recording control unit 73.

  Next, the recording reservation table update processing by the control unit 37 will be described with reference to the flowchart of FIG.

  In step S <b> 11, the manual recording control unit 72 determines whether or not a program recording is instructed based on the input signal supplied from the operation input unit 39.

  If it is determined in step S11 that the recording of the program has been instructed, the process proceeds to step S12, and the manual recording control unit 72 includes the program instructed to be recorded, which is included in the input signal supplied from the operation input unit 39. Reservation information for reserving recording of a program is generated, and the generated reservation information is supplied to the recording reservation table holding unit 74 based on the information indicating the above and the program distribution information supplied from the program distribution information holding unit 71. .

  Here, the program distribution information includes, for example, as shown in FIG. 7, the title of the program, the name of the broadcasting station that broadcasts the program, the broadcast date of the program, the broadcast start time of the program, the broadcast end time of the program, the genre, And meta information (words) indicating the contents of the program.

  In this case, the program distribution information includes the title of the program “Baseball Relay A”, the name of the broadcasting station that broadcasts the program “Broadcasting Station A”, the broadcasting date of the program “September 1, 2004”, and the broadcast start time of the program “16:00”, broadcast end time of the program “16:30”, genre “sports”, and the word “baseball” indicating the contents of the program are included.

  Note that the program distribution information may include only information on one program, or may include information on all programs broadcast during a predetermined number of days (for example, 8 days). Good.

  Therefore, for example, the program distribution information holding unit 71 holds the program distribution information shown in FIG. 7 and is broadcast from the operation input unit 39 from “16:00” on “September 1, 2004”. When an input signal indicating that the program title is “baseball broadcast A” and that the program is to be recorded is supplied, in step S12, the manual recording control unit 72 refers to the program distribution information shown in FIG. The program title is “Baseball Relay A”, the program broadcast date is “September 1, 2004”, and the program start time is “16:00”. Reservation information is generated, and the generated reservation information is supplied to the recording reservation table holding unit 74.

  In step S <b> 13, the recording reservation table holding unit 74 generates a recording reservation table based on the reservation information supplied from the manual recording control unit 72. The recording reservation table holding unit 74 updates the recording reservation table by holding the generated recording reservation table, and returns to step S11.

  Here, FIG. 8 is a diagram showing an example of the recording reservation table.

  The recording reservation table includes a reservation number indicating the order in which the recording of the program is reserved, the title of the program to be recorded, the broadcast date of the program to be recorded, the name of the broadcast station that broadcasts the program to be recorded, the broadcast start time of the program, And a manual recording flag indicating whether the program to be recorded is a program instructed to be recorded by the user.

  Here, the manual recording flag indicates whether or not the program to be recorded is a program instructed to be recorded by the user. The manual recording flag that is set (for example, set to “1”) indicates that the program reserved for recording is a program instructed to be recorded by the user, and has been reset. The manual recording flag (for example, set to “0”) indicates that the program reserved for recording is a program that is not instructed to be recorded by the user.

  That is, in the recording reservation table, the reservation number is “1”, the title is “baseball broadcast A”, the broadcast date is “September 1, 2004”, and the broadcast station is “broadcast station A”. Yes, the broadcast start time is “16:00”, the broadcast end time is “16:30”, and the recording of the program whose manual recording flag is set to “1” is reserved. include.

  In the recording reservation table, the reservation number is “2”, the title is “Drama D”, the broadcast date is “September 1, 2004”, and the broadcast station is “Broadcast station A”. , Includes information that is reserved for recording a program whose broadcast start time is “20:30”, broadcast end time is “21:30”, and manual recording flag is set to “0” The reservation number is “3”, the title is “Movie E”, the broadcast date is “September 3, 2004”, the broadcast station is “Broadcast station B”, and the broadcast start time Is “13:00”, the broadcast end time is “14:00”, and the manual recording flag is set to “1”.

  Similarly, in the recording reservation table, the reservation number is “4”, the title is “Sport A”, the broadcast date is “September 5, 2004”, and the broadcast station is “Broadcast Station C”. Yes, the broadcast start time is “11:00”, the broadcast end time is “12:00”, and the recording of the program whose manual recording flag is set to “0” is reserved. Included, reservation number is “5”, title is “Variety G”, broadcast date is “September 6, 2004”, broadcast station is “Broadcast station D”, and broadcast starts It includes information that is reserved for recording a program whose time is “13:00”, broadcast end time is “14:00”, and the manual recording flag is set to “1”. .

  Further, for example, a program whose reservation number is “1”, a program whose reservation number is “3”, and a program whose reservation number is “5” indicate that the recording is instructed by the user. The program having the reservation number “2” and the program having the reservation number “4” indicate that the recording is not instructed by the user.

  Returning to the description of the flowchart of FIG. 6, if it is determined in step S <b> 11 that the recording of the program has not been instructed, the user has not instructed the recording of the program, so the process proceeds to step S <b> 14 and the automatic recording control unit 73. Determines whether the recording device 13 has received the program distribution information. For example, in step S14, the automatic recording control unit 73 determines whether or not the program distribution information held by the program distribution information holding unit 71 has been updated, so that the recording device 13 has received the program distribution information. It is determined whether or not.

  If it is determined in step S14 that the program distribution information has been received, the program distribution information is supplied from the analog tuner 31, the digital tuner 33, or the communication unit 40 to the program distribution information holding unit 71, and the process proceeds to step S15. The automatic recording control unit 73 acquires the program distribution information from the program distribution information holding unit 71.

  In step S16, the recording candidate selection unit 92 of the automatic recording control unit 73 includes the program distribution information acquired from the program distribution information holding unit 71 by the automatic recording control unit 73 and the setting information holding unit 91 of the automatic recording control unit 73. Based on the stored setting information, a program to be an automatic recording candidate is selected from the programs indicated in the program distribution information.

  For example, the recording candidate selection unit 92 of the automatic recording control unit 73 indicates in the program distribution information when a keyword included in the setting information is included as a word indicating the content of the program indicated in the program distribution information. If a program is selected as an automatic recording candidate and the keyword included in the setting information is not included as a word indicating the content of the program indicated in the program distribution information, the program indicated in the program distribution information is automatically recorded. Do not select as a candidate.

  In step S <b> 17, the score calculation unit 77 selects the automatic recording candidate based on the meta information and the preference value of the content recorded in the recording unit 41 and the program distribution information supplied from the program distribution information holding unit 71. The calculated program score is calculated, and the calculated program score is supplied to the automatic recording control unit 73.

  Here, the recording unit 41 records, for example, content data, content meta information, and content preference values shown in FIG.

  That is, the recording unit 41 performs “content data A”, “meta information A” that is meta information of content reproduced by “content data A”, and a preference value “50” of content reproduced by “content data A”. "Is recorded.

  Similarly, the recording unit 41 selects “content data B”, “meta information B” that is meta information of content reproduced by “content data B”, and “preference value of content reproduced by“ content data B ””. 10 "is recorded, and" content data C "," meta information C "that is meta information of content reproduced by" content data C ", and a preference value" of content reproduced by "content data C" " 60 "is recorded.

  Further, for example, the score calculation unit 77 is included in the program distribution information based on the meta information and preference value of the content recorded in the recording unit 41 and the program distribution information supplied from the program distribution information holding unit 71. The score of the program that is the automatic recording candidate is calculated by adding the preference value of the content in which the word indicating the content of the program that is the automatic recording candidate is included in the meta information as the word indicating the content of the content To do.

  Therefore, for example, words indicating the contents of “program A” that is an automatic recording candidate included in the program distribution information are words indicating the contents of the contents in “meta information A” and “meta information C” illustrated in FIG. 9. Are included, the score of “program A” is a preference value “50” of content reproduced by “content data A” and a preference value “60” of content reproduced by “content data C”. It becomes "110 (50 + 60)" which is a value obtained by adding.

  Returning to the description of the flowchart of FIG. 6, in step S <b> 18, the automatic recording control unit 73 displays the program distribution information supplied from the program distribution information holding unit 71 and the score of the program that is the automatic recording candidate supplied from the score calculation unit 77. Based on the setting information, reservation information for reserving recording of the program is generated, and the generated reservation information is supplied to the recording reservation table holding unit 74.

  For example, if the recording device 13 can reserve up to five program recordings and the recording reservation table holding unit 74 holds the recording reservation table shown in FIG. 8, the reservation number is “1”. Since the program, the program with the reservation number “3”, and the program with the reservation number “5” indicate that the recording is instructed by the user, the automatic recording control unit 73 sets the reservation number. The recording reservations of the program with “1”, the program with the reservation number “3”, and the program with the reservation number “5” are not updated.

  That is, the automatic recording control unit 73 is a candidate for automatic recording and recording of each of the program with the reservation number “1”, the program with the reservation number “3”, and the program with the reservation number “5”. Reservation information for reserving recording of programs is generated so that recording of two programs is reserved in descending order of program scores.

  In step S 19, the recording reservation table holding unit 74 generates a recording reservation table based on the reservation information supplied from the automatic recording control unit 73. The recording reservation table holding unit 74 updates the recording reservation table by holding the generated recording reservation table, and returns to step S11.

  On the other hand, if it is determined in step S14 that the program distribution information has not been received, the control unit 37 does not update the recording reservation table, so the process returns to step S11 and the above-described processing is repeated.

  In this way, the recording device 13 calculates the score of the program that is an automatic recording candidate, and reserves recording of the program in descending order of score. The recording device 13 updates the recording reservation table every time the program distribution information is updated.

  As described above, the recording device 13 calculates the score of the program that is an automatic recording candidate and reserves recording of the program in descending order of score, so that the recording device 13 can reserve recording. The number of reservations can be maximized.

  Further, since the recording device 13 updates the recording reservation table every time the program distribution information is updated, the program that the user seems to prefer is always selected in response to changes in the program distribution information. This makes it possible to more efficiently record a program that seems to be a user's preference.

  Next, program recording processing by the recording device 13 will be described with reference to the flowchart of FIG.

  In step S51, the recording control unit 75 refers to the recording reservation table held in the recording reservation table holding unit 74 and determines whether there is a program whose broadcast start time is among the programs reserved for recording. Determine whether or not.

  For example, if the recording reservation table holding unit 74 holds the recording reservation table shown in FIG. 8 and the current time is 16:00 on September 1, 2004, the reservation number is “1”. Since the broadcast date of a certain program is “September 1, 2004” and the broadcast start time is “16:00”, the recording control unit 75 determines that there is a program at the broadcast start time.

  If it is determined in step S51 that there is no program that has reached the broadcast start time, there is no program to start recording, so the process returns to step S51, and the recording control unit 75 determines that there is a program that has reached the broadcast start time. The determination process is repeated until it is determined.

  On the other hand, if it is determined in step S51 that there is a program whose broadcast start time is reached, the process proceeds to step S52, where the analog tuner 31 or the digital tuner 33 receives the content data transmitted from the transmission station 11 or the satellite 12. To do.

  More specifically, when the analog tuner 31 receives an analog broadcast signal transmitted from the transmission station 11 or the satellite 12, the analog tuner 31 demodulates the received analog broadcast signal, and a moving image signal obtained by the demodulation. And the audio signal is supplied to the A / D converter 32. The A / D conversion unit 32 converts the moving image signal and the audio signal supplied from the analog tuner 31 from an analog signal to a digital signal, and converts the content data obtained by converting the moving image signal and the audio signal into the CODEC 34. To supply. Then, the CODEC 34 encodes the content data supplied from the A / D conversion unit 32 by a predetermined method such as MPEG2, and supplies the encoded content data to the recording control unit 75.

  When the digital tuner 33 receives a digital broadcast signal transmitted from the transmission station 11 or the satellite 12, the digital tuner 33 demodulates the received digital broadcast signal and obtains moving image data and audio data obtained by demodulation. Is supplied to the recording control unit 75.

  In step S <b> 53, the recording control unit 75 supplies the content data supplied from the digital tuner 33 or the CODEC 34 to the recording unit 41.

  In step S <b> 54, the recording unit 41 records the content data supplied from the recording control unit 75 under the control of the recording control unit 75. In more detail, the processing from step S52 to step S54 is repeated until the broadcast end time of the recorded program is reached.

  Since the recording of the program ends when the broadcast end time comes, the recording reservation table holding unit 74 is included in the held recording reservation table under the control of the recording control unit 75 in step S55. Among the information indicating that the recording is reserved, the information indicating that the recording of the program that has been recorded is reserved is deleted from the recording reservation table, the process returns to step S51, and the above-described processing is repeated.

  For example, when the recording device 13 records a program with the reservation number “1” shown in FIG. 8, the recording reservation table holding unit 74 controls the reservation number under the control of the recording control unit 75 in step S55. The information indicating that the recording of the program with “1” is reserved is deleted from the recording reservation table. That is, in this case, for example, broadcast date “September 1, 2004”, broadcast station “Broadcast station A”, broadcast start time “16:00”, broadcast end time “16” included in the recording reservation table. “30:30” is deleted, and the manual recording flag in the row of the reservation number “1” in the figure is reset (for example, set to “0”).

  In this way, the recording device 13 receives a program reserved for recording and records the received program.

  As described above, the recording device calculates the score of a program that is a candidate for automatic recording and reserves recording of the program in descending order of score, so that the number of reservations that the recording device can reserve recording is as follows. Can be used to the maximum.

  Further, since the recording apparatus updates the recording reservation table every time the program distribution information is updated, the program that the user seems to prefer is always selected in response to changes in the program distribution information. As a result, a program that seems to be a user's preference can be recorded more efficiently.

  According to the present invention, since the program is received, the program can be recorded. In addition, according to the present invention, since the score of a program that is a candidate for automatic recording is calculated and the recording of the program is reserved in descending order of the score, the number of reservations that the recording apparatus can make a reservation for recording is determined. It can be used to the fullest.

  Furthermore, according to the present invention, since the recording reservation table is updated every time the program distribution information is updated, the program that the user seems to prefer is always selected in response to changes in the program distribution information. This makes it possible to more efficiently record a program that seems to be a user's preference.

  Although it has been described that the score of a program that is a candidate for automatic recording is calculated based on the preference value of the recorded content, the preference of a predetermined word determined in advance based on the meta information of the recorded content A value may be calculated, and a score of content that is an automatic recording candidate may be calculated based on the calculated preference value.

  In this case, for example, the preference value calculation unit 76 holds in advance words that seem to indicate the content of the content that the user likes, such as “baseball”, “comed”, and “drama”. Then, the preference value calculation unit 76 calculates the preference value of the word held in advance by the preference calculation unit 76 based on the meta information of the content recorded by the recording unit 41.

  For example, when the preference value calculation unit 76 holds the word “baseball”, when the word “baseball” is included as a word indicating the content of the content recorded by the recording unit 41, the content of the content For each content including the word “baseball”, the preference value of the word “baseball” is increased by 1 point, and the title of the content recorded by the recording unit 41 includes the word “baseball”. When the content title includes the word “baseball” in the content title, the word preference value is calculated so that the preference value of the word “baseball” increases by 2 points.

  Therefore, in this case, for example, when the recording unit 41 records two contents including the word “baseball” as a word indicating the content, the word is set so that the preference value increases by 2 points. The preference value for “baseball” is calculated.

  The score calculation unit 77 calculates the score of the content that is an automatic recording candidate based on the word preference value calculated by the preference value calculation unit 76. For example, when the word held by the preference value calculation unit 76 is included as a word indicating the content of a program that is an automatic recording candidate, the score calculation unit 77 adds the preference value of the word as the program score. As shown, the program score is calculated.

  Therefore, for example, when the preference value of the word “sports” held by the preference value calculation unit 76 is “10” and the preference value of the word “baseball” is “30”, the program that is a candidate for automatic recording is recorded. The score of a program that includes the words “sports” and “baseball” as words indicating the contents is “40 (10 + 30)”.

  Further, for example, when the preference value of the word held by the preference value calculation unit 76 is calculated, the point of the content instructed to be recorded by the user may be calculated twice. Therefore, for example, when the preference value calculation unit 76 holds the word “baseball”, the word “baseball” is included as a word indicating the content of the content recorded by the recording unit 41, and the content Is not the content instructed by the user, the preference value is calculated so that the preference value of the word “baseball” is increased by 1 point, the word “baseball” is included, and the recording of the content is For the content instructed by the user, the preference value is calculated so that the preference value of the word “baseball” is increased by 2 points.

  Further, it has been described that the recording device generates a recording reservation table and records a program based on the recording reservation table. However, in a predetermined device, the recording reservation table or reservation information is generated, and the generated recording reservation table or reservation information is generated. May be transmitted to the recording apparatus by wired or wireless communication. In this case, the recording device receives the recorded recording reservation table or reservation information, and records the program based on the received recording reservation table or reservation information.

  Furthermore, it has been described that the recording device receives a program by receiving a terrestrial wave or a satellite wave. However, the recording device may receive a cable television broadcast program or the like by wired or wireless communication. The receiving method does not limit the present invention.

  The series of processes described above can be executed by hardware, but can also be executed by software. When a series of processing is executed by software, a program constituting the software may execute various functions by installing a computer incorporated in dedicated hardware or various programs. For example, it is installed from a recording medium in a general-purpose personal computer.

  A program for causing such a computer to execute the series of processes described above is supplied to the computer in a state of being stored in a recording medium, and loaded into a RAM or the like for execution.

  The program for executing the series of processes described above is installed in a computer via a wired or wireless communication medium such as a local area network, the Internet, or digital satellite broadcasting via an interface such as a router or a modem as necessary. You may be made to do.

  Further, in the present specification, the step of describing the program stored in the recording medium is not limited to the processing performed in chronological order according to the described order, but is not necessarily performed in chronological order. It also includes processes that are executed individually.
