Japanese Patent Laid-Open No. 10-42247 JP 2004-208204 A JP-A-8-329558

  By the way, in a conventional information recording / reproducing apparatus, a user can watch a recorded program at any time by recording a TV program and recording it on a recording medium (such as a hard disk or a DVD). If the number of recorded programs such as news and weather forecasts that are broadcast many times increases, the recording medium area will be used for recording programs, and it will be used more and more, so the old recorded programs will be deleted. However, when deleting an old recorded program, the user has to select and delete the recorded program to be deleted one by one by remote control operation. Also, programs that are broadcast many times a day, such as news and weather forecasts, are meaningful for viewing the latest program, so when viewing, you must search for the latest program, There was a problem that the remote control operation was troublesome.

  In the prior art of Patent Document 1, there is a key screen designating unit for selecting and designating a key screen that appears as a similar pattern each time in a program to be recorded from video information based on a received television signal. The key screen storage means for storing the key screen designated by the key screen designation means, and the moving picture information based on the received television signal is monitored and the key screen appears in the moving picture information. Key screen detecting means for detecting, and moving picture storing means for storing the moving picture information for a preset time when the key screen is detected by the key screen detecting means are provided.

  However, in this prior art, in order to perform an operation of selecting a key screen that appears as a similar pattern each time in a program to be recorded from moving image information based on a received television signal, the power of the apparatus is always turned on. Since it must be turned on, power consumption is wasted and the life of the apparatus is shortened. Further, the process of monitoring the moving picture information based on the received television signal and detecting that the key screen appears in the moving picture information handles the moving picture information, and thus the process becomes complicated.

  In the prior art of Patent Document 2, content whose number of playbacks is one or more based on the recording date and time and the number of playbacks of the content managed by the content management means from among the content not set for automatic deletion prevention On the other hand, the content with the smallest number of reproductions and the oldest recorded date and time is deleted. This prevents the recording capacity of the hard disk from becoming insufficient, but programs that are broadcast many times a day, such as news and weather forecasts, are meaningful for viewing the latest programs. In addition, as described above, based on the recording date and time of the content and the number of times of reproduction, the processing for deleting the content with the smallest number of reproductions and the oldest recorded date and time may be applied to the content with the number of times of reproduction of one or more. , It doesn't make much sense because you don't watch news and weather forecasts of the same date many times.

  In the prior art of Patent Document 3, for example, only the news is recorded on a specific magnetic tape, and a new program is recorded while erasing a program whose recording date is earlier, so that the latest news can be reproduced at any time. Although the recording medium in this case is a magnetic tape, the configuration in the case where the recording medium is a hard disk or a DVD is fundamentally different. This information recording / reproducing apparatus cannot be applied.

  The present invention has been made to solve the above-described problems, and is an information record that allows the latest information of programs broadcast many times a day, such as news and weather forecasts, to be viewed at any time. An object is to provide a playback device.

As described above, when the areas E1, E2, E3 allocated in advance in the DVD 13 or HD 14 are filled with the data of the weather forecast program, the data of the oldest weather forecast recorded program is automatically deleted, so that the user can The operation eliminates the need to select and delete the recorded programs to be deleted one by one, and it is also easy to search for the latest information on programs that are broadcast many times a day, such as news and weather forecasts.

  FIG. 3 is a diagram showing the contents of the recording information in this embodiment. In FIG. 3, “category” indicates a program name in which a plurality of programs such as news broadcasted several times a day and weather forecast are classified for each similar program. In this example, the weather forecast The weather forecast program classified by is shown. “Recording date and time” shows the date and time when the weather forecast program was reserved for recording, and “Channel” shows the channel of the television broadcast station on which the weather forecast program was broadcast. The “assigned area” indicates an area name (corresponding to address information) of an assigned area in which the weather forecast program is recorded (recorded) among areas previously assigned to the recording medium (DVD 13 or HD 14).

  In the case of the example in FIG. 3, the weather forecast program T1 is broadcast on the channel CH2 and is recorded at 7:00 on January 5, 2006, and is recorded in the allocation area E1. The weather forecast program T2 is broadcast on the channel CH4 and recorded at 9:00 on January 5, 2006, and is recorded in the allocation area E2. The weather forecast program T3 is broadcast on the channel CH2 and is recorded at 13:00 on January 5, 2006, and is recorded in the allocation area E3. The weather forecast program T4 is broadcast on the channel CH6, is recorded at 15:00 on January 5, 2006, and is recorded in the allocation area E1. The weather forecast program T5 is broadcast on the channel CH2 and is recorded at 18:00 on January 5, 2006, and is recorded in the allocation area E2. The weather forecast program T6 is broadcast on the channel CH8 and recorded at 20:00 on January 5, 2006, and is recorded in the allocation area E3.

  On the next day, the weather forecast program T1 is broadcast on the channel CH2 and recorded at 7:00 on January 6, 2006, and is recorded in the allocation area E1. The weather forecast program T2 is broadcast on the channel CH4, recorded at 9:00 on January 6, 2006, and is recorded in the allocation area E2. The weather forecast program T3 is broadcast on the channel CH2 and is recorded at 13:00 on January 6, 2006, and is recorded in the allocation area E3. The weather forecast program T4 is broadcast on the channel CH6, is recorded at 15:00 on January 6, 2006, and is recorded in the allocation area E1. The weather forecast program T5 is broadcast on the channel CH2 and is recorded at 18:00 on January 6, 2006, and is recorded in the allocation area E2. The weather forecast program T6 is broadcast on the channel CH8, is recorded on January 6, 2006 at 20:00, and is recorded in the allocation area E3.

  Similarly, every day a new weather forecast program is recorded. Note that if the unnecessary information in the recording information of the weather forecast program as shown in FIG. 3 is deleted, the area of the recording medium on which the recording information is recorded can be used effectively. In this example, the weather forecast program has been described, but the same processing can be performed for news and the like.

  FIG. 4 is a flowchart for explaining the processing when, for example, a weather forecast program is recorded in this embodiment. A process for recording a weather forecast program will be described with reference to this flowchart and FIGS. Here, the weather forecast program is described as being recorded (recorded) on the HD 14.

  First, when the remote controller 11 is operated to display an EPG (electronic program guide) received by the tuner 4 on the display device 131 of the monitor device 13 and an operation for making a reservation for recording one day of the weather forecast program is performed, the system controller The recording reservation setting means of the 10 recording processing units 101 sets the recording reservation contents of the weather forecast program in the flash memory 6 (step S1). In this case, the contents of the recording reservation are, for example, the weather forecast program T1 from the EPG on the channel CH2 at the broadcast start time of 7:00, the weather forecast program T2 at the channel CH4 at the broadcast start time of 9:00, and the broadcast start time on the channel CH2. Is the weather forecast program T3 at 13:00, the weather forecast program T4 at 15:00 on the channel CH6 and the broadcast start time at 15:00, the weather forecast program T5 at the broadcast start time at 18:00 on the channel CH2, and the weather at 20:00 on the channel CH8. If each forecast program T6 is reserved for recording, the weather forecast program is automatically recorded every day if the date is updated the next day and the same recording reservation information is used. For recording reservation, a G code may be used instead of EPG.

  After the weather forecast program is reserved for recording in this way, when the current time becomes the recording start time by a timer (not shown) (step S2), the recording determination unit of the recording processing unit 101 uses the set recording reservation. Is determined based on the recording reservation information as to whether or not it is a recording reservation of a program (a weather forecast program in this example) classified into a plurality of programs of the same kind as a plurality of programs broadcasted several times a day ( Step S3). If it is determined that the recording reservation is for a program (weather forecast program) classified for each similar program, the area determination means of the recording processing unit 101 drives the hard disk device 3 and is the HD 14 allocated area insufficient? Determine whether or not. That is, the area determination means determines whether or not the allocated area E1, E2, E3 shown in FIG. 2 is recorded (recorded) in the weather forecast recording program (recorded program data) and the allocated area is insufficient. Determine (step S4).

  When it is determined that the allocated area is insufficient, the recorded program erasing unit of the recording processing unit 101 drives the hard disk device 3 to record the old recorded program recorded in the allocated area (see FIG. 2) of the HD 14. Erasing (step S5). That is, for example, as shown in FIG. 2, when the weather forecast programs T1, T2, and T3 are recorded in the allocated areas E1, E2, and E3, respectively, the recorded program erase means erases the oldest weather forecast program T1. The Then, the recording processing unit 101 starts recording the next weather forecast program T4 in the allocation area E1 (step S7). If the data of the weather forecast program T4 in the assignment area E1 is overwritten with the data of the weather forecast program T4, the new weather forecast program T4 is recorded (recorded) in the assignment area E1.

  On the other hand, if it is determined in step S3 that the program is not scheduled to be recorded for the same type of program (weather forecast program), the system controller 10 refers to the recording reservation information stored in the flash memory 6 and reads the normal recording reservation information. It is determined whether or not there is a recording reservation for a program (a program other than a plurality of programs such as news and weather forecasts broadcasted several times a day) (step S6). The apparatus 3 is driven to start recording the program on the HD 14 (step S7).

  When the current time is the recording end time (step S8) and the recording is stopped (step S9), the recording processing unit 101 records the recording information as shown in FIG. It is stored in the HD 14 via the device 3 (step S10). After this, if there is a recording reservation (step S11), the process returns to step S2 and the same processing is performed. When there is no recording reservation, the recording process ends. Note that the recording reservation of the weather forecast program does not need to be recorded every day, and the processing from step S2 to step S11 is repeated until the recording reservation is canceled by the user's remote control operation.

  In the flowchart of FIG. 4, the recording process of the weather forecast program has been described. However, any news program that is broadcast many times every day or any program that wants to view the latest information in a program that is broadcast many times every day can be used. The same effect can be obtained by similar processing. Further, here, the weather forecast program or the like has been described as being recorded (recorded) on the HD 14, but the same recording process can be performed when the weather forecast program or the like is recorded (recorded) on the DVD 13.

  FIG. 5 is a flowchart for explaining a process when, for example, a weather forecast program is reproduced in the present embodiment. Processing for reproducing a weather forecast program will be described with reference to this flowchart and FIGS.

  First, since the user wants to watch the latest weather forecast, when the playlist is displayed on the display device 131 of the monitor device 13 by remote control operation and the weather forecast is selected from the playlist, the playback processing unit 102 of the system controller 10 is selected. The program selection operation determining means detects that the weather forecast has been selected and operated (step N1), and the latest recorded program search means of the reproduction processing unit 102 drives the hard disk device 3, and the selected weather forecast is selected. The recorded program of the latest weather forecast from the recording information (see FIG. 3) is searched from the allocation area (see FIG. 2) of the HD 14 based on the recording date and time information (step N2).

  When the latest program determination unit of the reproduction processing unit 102 determines that there is no recorded program for the weather forecast by the search (step N3), the message display unit of the reproduction processing unit 102 is stored in the flash memory 6. The message data is read out, OSD-processed by the OSD circuit 12, and a message “Weather forecast is not recorded” is displayed on the display device 131 of the monitor device 13 via the video output unit 7 (step N4).

  On the other hand, when the latest program determination unit of the reproduction processing unit 102 determines that the latest weather forecast recorded program is in the allocation area of the HD 14 (step N3), the reproduction start unit of the reproduction processing unit 102 includes the hard disk device 3 Is read out from the assigned area of the HD 14 based on the recording date and time of the recording information, and playback is started (step N5), and the latest weather forecast recorded program is read from the video output unit 7. The video signal is supplied to the display device 131 of the monitor device 13, and the audio signal of the latest weather forecast recording program is supplied from the audio output unit 8 to the speaker 132 of the monitor device 13. As a result, the latest weather forecast is displayed on the display device 131, and the sound related to the latest weather forecast is output from the speaker 132. When the reproduction is finished (step N6), the reproduction process is finished.

  As described above, according to the present embodiment, since a program is recorded (recorded) in the allocation area of the recording medium such as news broadcasted many times or weather forecast, the area of the recording medium Can be used effectively, and the latest information of the program can be viewed at any time. Also, if you want to watch the latest information on multiple programs that are broadcast many times a day, such as news and weather forecasts, the user only has to select and play back news and weather forecasts. You can always watch the latest information.
