Description

  The present invention relates to a recording apparatus that receives a broadcast signal and records a program included in the broadcast signal on a recording medium. Further, the present invention relates to a recording apparatus having a reservation recording function for recording a program by setting a recording start time and an end time in advance.

  Conventionally, recording devices such as a video deck and a hard disk recorder that record a TV program record the TV program while the user is away by setting the recording start time and end time in advance. It has a reservation recording function. In recent years, a program guide is displayed using electronic program guide information (hereinafter referred to as EPG (Electronic Program Guide)) transmitted together with a program, and a program to be recorded is selected from the program guide. Recording apparatuses capable of making reservations have been put into practical use.

  Patent Document 1 proposes a program search apparatus that can search a program including a keyword input by a user from an EPG and automatically record the searched program. As a result, for example, when the user inputs “soccer” as a keyword, all football relays are automatically recorded, so there is no need for the user to make a reservation for each program and there is less possibility of missing a desired program. There is an advantage of becoming.

  However, for sports programs such as baseball or soccer, the game may not end within the scheduled time, and the broadcast time of the program may be extended. Even when the broadcast time is extended, the scheduled recording ends at the set end time, so that there is a problem that the sports program cannot be recorded to the end. Moreover, even if the program itself is a program such as a drama or a movie that is not extended, when it is broadcast after a sports program, the program start time and end time are delayed, so the program cannot be recorded to the end. There is a problem.

  In digital broadcasting, when an extension of a program occurs, the EPG is automatically updated. Therefore, the recording apparatus that receives the updated EPG records the program by changing the start time and end time of the recording reservation. be able to. However, in the case of analog broadcasting, the EPG is not updated even if the program is extended. Therefore, since the recording device that records the analog broadcast program cannot determine the extension of the program, the recording reservation cannot be automatically changed, and the user ends the recording reservation in consideration of the possibility of the extension. The problem was solved by setting the time later.

In Patent Document 2, a keyword including the possibility of extending broadcast time, for example, a program including “maximum extension” is searched from the EPG, and time information indicating the maximum extension time associated with this keyword is read and read. A recording / playback apparatus that changes the end time of a recording reservation according to time information has been proposed. As a result, it is possible to record a program whose broadcast time may be extended or a program whose broadcast start time and end time may be delayed to the end.

The broadcast time of the program related to the recording reservation can be changed depending on whether the program includes the keyword stored by the keyword storage means and the broadcast time of the program is longer than a predetermined reference time. It is characterized by comprising determination means for determining whether or not there is a property.

  In the present invention, when a program related to recording reservation includes a predetermined keyword and the broadcast time is longer than a predetermined reference time, it is determined that the program may change the broadcast time. In many cases, programs such as baseball or soccer that may be extended in broadcast time are about 2 hours in broadcast time. On the other hand, programs such as sports news that may include keywords such as baseball or soccer are not extended in broadcast time, and the broadcast time is often about one hour. For this reason, when the determination is performed, the accuracy of the determination is improved by comparing the reference time with the broadcast time. As a result, when a program such as baseball or soccer is reserved and recorded, the program such as baseball or soccer can be determined as a program whose broadcasting time may be extended, so the recording time of the recording reservation is changed.

To.

  In the present invention, when a program broadcast in the previous time zone on the same channel as a program related to recording reservation includes a predetermined keyword and the broadcast time is longer than a predetermined reference time, the program related to recording reservation is It is determined that the program may have a longer broadcast time. In many cases, programs such as baseball or soccer that may be extended in broadcast time are about 2 hours in broadcast time. On the other hand, programs such as sports news that may include keywords such as baseball or soccer are not extended in broadcast time, and the broadcast time is often about one hour. For this reason, when the determination is performed, the accuracy of the determination is improved by comparing the reference time with the broadcast time. Thereby, since a program such as a drama or a movie broadcast after baseball or soccer can be determined as a program whose broadcast time may be changed, the recording time of the recording reservation can be changed.

  The recording apparatus according to the present invention further includes a reference time receiving unit that receives a reference time for the determination unit to make a determination.

  In the present invention, the input of the reference time from the user is accepted, and the received reference time is used for comparison with the broadcast time of the program.

Since the user can input the extension time, the optimum extension time can be determined according to the broadcast status of the program or the content of the EPG, and the end time of the recording reservation can be delayed.

  According to the present invention, when the program related to the recording reservation is longer than the predetermined reference time and includes the predetermined keyword, the program related to the recording reservation is determined to be a program whose broadcasting time may be changed. By adopting such a configuration, it is possible to more reliably determine a program whose broadcast time may be extended, and to reduce the possibility of erroneous determination of a program that is not actually extended. Thus, the program can be determined as a program whose broadcasting time may be extended, and the recording time of the recording reservation can be changed by the user, thereby reducing the possibility of missing a desired program.

  In addition, according to the present invention, when a program broadcast in the previous time zone on the same channel as the program related to the recording reservation includes a predetermined keyword, the broadcasting time of the program related to the recording reservation may be changed. By adopting a configuration that determines that there is a certain program, it is possible to more reliably determine a program whose broadcast time may be extended, and to reduce the possibility of erroneously determining a program that is not actually extended. Therefore, a program such as a drama or a movie that is broadcast after a program that may be broadcast in an extended manner, such as baseball or soccer, can be determined as a program whose broadcasting time may be changed, and the user reserves a recording reservation. Recording time can be changed, and the possibility of missing a desired program can be reduced.

  Further, in the case of the present invention, by accepting the input of the reference time from the user and comparing with the broadcast time of the program using the received reference time, the broadcast status of the program, the contents of the EPG, etc. Accordingly, since a more accurate reference time can be set, it is possible to more reliably determine a program whose broadcast time may be extended, and erroneously determine a program that is not actually extended The risk of doing so can be reduced.

  Further, according to the present invention, by receiving a keyword input from a user and adding or changing a keyword used for determining a program that may change the broadcast time, Since a keyword with higher accuracy of determination can be set according to the content of the EPG, etc., it is possible to more reliably determine a program whose broadcast time may be changed, and the user can select a desired program. The possibility of overlooking can be reduced.

  Further, according to the present invention, when there is a possibility that the broadcast time of a program related to a recording reservation may be changed, the recording time of the recording reservation is changed, so that a desired program can be reliably recorded to the end. Therefore, the possibility that the user misses the desired program can be reduced.

  Further, in the case of the present invention, an extension time is received from the user, and the recording reservation end time is delayed according to the received extension time, so that the user can respond according to the broadcast status of the program or the content of the EPG. Since the optimum extension time can be determined and the recording reservation end time can be delayed, the usability of the recording apparatus can be improved.

If the setting has not been completed (S33: NO), the process returns to step S32 to continue displaying the extension setting screen. When the setting of the extension time is completed (S33: YES), the recording reservation end time is extended (step S34).

  When the program broadcast in the time zone before the program related to the recording reservation in step S31 does not match the program searched for the possibility that the broadcast time is extended (S31: NO), and step S34 After extending the recording reservation end time, a reservation confirmation screen display command is given to the selection unit 16 to display the reservation confirmation screen (step S35).

  FIG. 11 is a display example of a reservation confirmation screen displayed by the hard disk recorder 1 according to the present invention. On the reservation confirmation screen, the recording date of the program, the recording start time, the recording end time, the broadcast channel, the image quality when recording, and the extended time of the end time are displayed for the program selected from the EPG. Further, the remaining time that can be recorded on the hard disk 19 and the recording time of the program reserved for recording are displayed together. For example, FIG. 11 shows a setting for recording a program broadcast on 6 channels from 9 pm to 10 pm on December 25 with standard image quality. Since the extension time is set to 30 minutes, the recording time is 1 hour and 30 minutes.

  At the bottom of the reservation confirmation screen, two rectangular boxes are arranged side by side. In the box on the left side, the word “complete” is written to complete the recording reservation setting. In the box on the right, the text “To detailed settings” is written, and a screen for changing the recording image quality, setting the start time and end time in 1 minute units, and setting the extended time in detail (illustrated) Is omitted). The rectangular cursor 36 surrounding the box is moved to the left and right by the cursor keys provided on the operation unit 22 or the remote controller 52, and the “OK” button is pressed to complete the setting or display the detailed setting screen. be able to.

  After the reservation confirmation screen is displayed in step S35, it is checked whether or not the reservation setting is completed (step S36). If the reservation setting is not completed (S36: NO), the process returns to step S35 and the display of the reservation confirmation screen is continued. When the reservation setting is completed (S36: YES), the reservation content is stored in the recording reservation storage unit 21b of the memory 21 (step S37), and the process is terminated.

  In the hard disk recorder 1 having the above configuration, a program including five keywords stored in the extension condition storage unit 21c is searched from the EPG, and a program whose broadcast time is longer than the reference time is searched from among the programs. Therefore, it is possible to search for a program whose broadcast time may be extended more reliably, and from this search result, it is possible to more reliably determine whether or not the broadcast time of the program related to the recording reservation is changed. Therefore, the possibility of erroneous determination of a program that is not actually extended can be reduced.

  In the present embodiment, the configuration in which the memory 21 is provided with the EPG storage unit 21a, the recording reservation storage unit 21b, and the extension condition storage unit 21c is shown, but the present invention is not limited to this. A configuration in which part or all of the hard disk 19 is provided may be employed. Further, although five keywords are stored in the extension condition storage unit 21c, the number of keywords is not limited to this, and may be four or less or six or more. Moreover, although the structure which a user can add or change the keyword used for determination of the program which may be extended was shown, it is not restricted to this, A user cannot add or change, Only a predetermined keyword is shown. The structure to be used may be used. In addition, the recording reservation is set by selecting a program from the EPG program guide. However, the present invention is not limited to this, and the user sets the recording reservation by directly inputting the start time and the end time. It may be a configuration.

  In the flowcharts shown in FIG. 7 and FIG. 8, the search performed in steps S25 and S26 is a program related to a recording reservation, a program broadcast in a time zone before this program, and broadcast on the same channel. However, the present invention is not limited to this, and only programs related to recording reservations or only programs broadcast on the same channel that are broadcast in the time zone before the programs related to recording reservations are searched. It may be a target. Further, not only programs broadcast on the same channel but also programs broadcast on all channels may be searched. In addition, a search for a program that may be extended is performed when a recording reservation is set. However, the present invention is not limited to this. For example, when an EPG is acquired, the EPG is searched. The configuration may be performed in advance for all included programs.

  Moreover, the display example shown in this embodiment is an example, and the present invention is not limited to this. In this embodiment, the hard disk recorder 1 has been described as an example of the recording device. However, the present invention is not limited to this, and other recording devices such as a video tape recorder, a DVD recorder, or a Blu-ray recorder may be used. Alternatively, the recording apparatus may include a plurality of recording media.
