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.

Furthermore, you can display detailed information about the program by pressing the “blue” button, search for the program by pressing the “red” button, and press the “green” button. The date and time of the program guide to be displayed can be selected.

  After displaying the program guide in step S13, it is checked whether or not a program for recording reservation has been selected from the program guide (step S14). If no program is selected (S14: NO), the process returns to step S13, and the display of the program table is continued. When a program is selected (S14: YES), a program whose broadcast time may be extended from the EPG is searched using the keyword stored in the keyword storage unit 21c (step S15). The search target to be searched at this time is a program related to recording reservation and a program broadcast in the time zone before this program and broadcast on the same channel.

  Next, it is checked whether or not the program searched for the possibility that the broadcast time may be extended matches the program related to the recording reservation (step S16). In addition, the case where it corresponds is a case where the program which concerns on a recording reservation is a program, such as baseball or soccer, and the case where the recording reservation program itself is extended. If they match in step S16 (S16: YES), the possibility of extension of the program searched in step S15 is calculated (step S17).

  The calculation of the possibility of extension performed in step S17 is performed using the following equation (1). In the equation (1), P is a possibility that the program is actually extended. Ki (i = 1 to 5) is whether or not a keyword is included in the program information of the program. If it is included, 1 is substituted as a value, and 0 is substituted if it is not included. Wi (i = 1 to 5) is a weight of each keyword. Wa is the sum of the weights of the five keywords.

  For example, as shown in Table 1, when keywords and the weight of each keyword are set, if the program information of the program includes two keywords “extension” and “baseball”, this program is actually The possibility of being extended to 53% is calculated as shown below.

  After calculating the possibility of extension in step S17, the user gives an instruction to display an extension setting screen for extending the recording reservation end time to the selection unit 16 to display the extension setting screen (step S18). .

  FIG. 9 is a display example of an extension setting screen displayed by the hard disk recorder 1 according to the present invention. The extension setting screen is an extension setting window 35 superimposed on a later-described reservation confirmation screen. In the extension setting window 35, a message is displayed informing the user that the broadcast time of the program related to the recording reservation may be changed. In this message, the possibility of extension calculated in step S17 is displayed. Under the message display, five rectangular boxes are arranged side by side. The extension time is described in each box, and is “not extended”, “30 minutes extended”, “60 minutes extended”, “90 minutes extended” and “120 minutes extended” in order from the left. The rectangular cursor 36 surrounding the box is moved left and right by the cursor keys provided on the operation unit 22 or the remote controller 52, and the “determine” button is pressed to set the extension time of the recording reservation end time. be able to.

  After the extension setting screen is displayed in step S18, it is checked whether or not the setting is completed (step S19). If the setting has not been completed (S19: NO), the process returns to step S18 to continue displaying the extension setting screen. When the setting of the extension time is completed (S19: YES), the recording reservation end time is extended (step S20).

  In step S16, if the program searched that the broadcast time may be extended does not match the program related to the recording reservation (S16: NO), and after extending the recording reservation end time in step S20 Then, it is checked whether or not the program broadcast in the time zone before the program related to the recording reservation matches the program searched if the broadcast time may be extended (step S21). If they match (S21: YES), that is, if the program related to the recording reservation is a drama or a movie broadcast after a program such as baseball or soccer, the possibility of extending the program searched in step S15 is displayed. Calculate (step S22). The calculation method is the same as in step S17.

  After calculating the possibility of extension, the extension setting screen shown in FIG. 9 is displayed (step S23). Next, it is checked whether or not the setting of the extension time by the user has been completed (step S24). If the setting has not been completed (S24: NO), the process returns to step S23 and the display of the extension setting screen is continued. When the setting of the extension time is completed (S24: YES), the recording reservation end time is extended (step S25).

  If it is determined in step S21 that the program broadcast in the time zone before the program related to the recording reservation does not match the searched program if there is a possibility that the broadcast time is extended (S21: NO), and step S25 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 S26).

  FIG. 10 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. 10 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 S26, it is checked whether or not the reservation setting is completed (step S27). If the reservation setting is not completed (S27: NO), the process returns to step S26 and the display of the reservation confirmation screen is continued. When the reservation setting is completed (S27: YES), the reservation content is stored in the recording reservation storage unit 21b of the memory 21 (step S28), and the process is terminated.

  In the hard disk recorder 1 having the above configuration, since the user can add or change a keyword for searching the EPG for a program whose broadcasting time is extended from the keyword setting screen shown in FIG. It is possible to set keywords according to the contents and the broadcast status of the program, etc., to improve the search efficiency. Further, the keyword content rate of the searched program, that is, how many of the five keywords are included in the program information of the program is displayed to the user as the possibility of extension, so that the user can make a recording reservation. It becomes easier to determine whether or not to extend the end time. When calculating the possibility of extension by weighting each keyword, by calculating the keyword content rate, that is, the possibility of extension, considering the weight of each keyword, using the calculation formula shown in equation (1) The possibility of extension according to the contents of the EPG and the broadcast status of the program can be calculated.
