Description

  The present invention relates to a recording / reproducing apparatus for recording / reproducing a television program and the like, and particularly to a technique effective when applied to management of a recorded program.

  Increase in capacity and cost of main recording media built into devices such as HDDs (hard disk drives), increase in recording / reproducing access speed to main recording medium, increase in recording / reproducing transmission speed, and image signals including moving images As the speed of the process of compressing and encoding audio signals has advanced, these technologies can be used to compress and record image signals and audio signals of TV programs, and to decode and reproduce them. In addition, a recording / reproducing apparatus capable of dubbing a recorded program in the main recording medium HDD to a second recording medium that can be attached to and detached from the apparatus such as a DVD-R for long-term storage has been commercialized. .

  According to such a recording / playback apparatus, it is possible to record image signals and audio signals of a plurality of television programs on a large-capacity main recording medium represented by an HDD. For example, a recording / playback device equipped with a 400 GB large-capacity HDD can record video data of a huge program in a long time of about 360 hours in the LP recording mode and about 180 hours in the SP recording mode. A DVD-R that is a possible second recording medium is a DVD-R medium having a capacity of 4.7 GB per image, and the video is about 4 hours in the LP recording mode and about 2 hours in the SP recording mode. Data can be recorded.

  For this reason, in such a recording / playback apparatus, a function for setting a program to be recorded so that a plurality of programs can be reserved and a program broadcasted multiple times such as a daily weather forecast and a continuous drama It is desirable to have a function that can be set with one recording reservation. It is also desirable to have a function for displaying a list of recorded programs and a function for erasing already viewed programs.

  However, as the capacity of the HDD increases, the number of programs recorded and stored in the HDD becomes enormous. Therefore, it is possible to view programs that are no longer required to be stored after viewing, such as a weather forecast program two days ago. Since it is necessary for the user to delete a large number of programs that are no longer required to be stored by an erasing operation whenever necessary, the burden on the user increases and the risk of the user erroneously deleting the recorded program increases.

  Therefore, in the past, when a program that is broadcast multiple times is recorded with one recording reservation, the program recorded at the time of the previous broadcast is automatically recorded immediately before the recording is performed at the time of the current broadcast (such as one minute before). In some cases, it is possible to reduce the burden of the user's erasing operation by erasing (see, for example, Patent Document 1).

In addition, when a program that is broadcast multiple times is recorded with one recording reservation, the user sets an automatic deletion interval and automatically deletes it at that interval, reducing the burden of the user's deletion operation Some have made it possible (see, for example, Patent Document 2).

  Patent Documents 1 and 2 alleviate the burden of the user's erasure operation only when a program that is broadcast multiple times is recorded with a single recording reservation. On the other hand, there is still a problem to be improved that the burden of the user's erasing operation and the risk of erroneous erasing cannot be reduced.

  Further, as the capacity of the HDD is increased, the number of programs recorded and stored in the HDD becomes enormous, and the following problems become prominent.

  The first problem is that the program recorded and stored in the HDD is not only an unwatched program that the user wants to watch, but also a news program or a weather forecast recorded program several days ago even if it is not watched. Stored for the purpose of permanent storage regardless of whether it has not been viewed or watched, such as programs that have lost value, recorded programs of continuous drama every morning, etc. Since there are a huge number of programs that have already disappeared and programs that have not been watched yet, but the user has not deleted them, This means that it is difficult for users to find the essential recording program they want to watch.

  The second problem is that when a recorded program in the HDD is dubbed to a second recording medium that can be attached to and detached from the apparatus such as a DVD-R for long-term storage, the program recorded and stored in the HDD Is enormous, and the user cannot easily determine which program is stored on the second recording medium for the purpose of dubbing. Another problem is that the user cannot easily determine whether or not a recorded program to be dubbed on the DVD-R has been stored in the HDD in a necessary and sufficient capacity.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to make it easier for a user to search for a recorded program to be reproduced in a recording / reproducing apparatus having a main recording medium capable of recording a large number of recorded programs. It is an object of the present invention to provide a recording / reproducing apparatus that can easily discriminate a program and can reduce the burden of a user's erasing operation and the risk of erroneous erasure of a large number of recorded programs.

  A recording / playback apparatus according to the present invention includes a recording medium for recording content including encoded video data, a recording reservation setting unit for setting a recording reservation, and a program on the recording medium based on the recording reservation setting by the recording reservation setting unit. A recording / playback apparatus for recording and playing back video data, an expiration date setting means for setting an expiration date for a program reserved for recording, and an expiration date of the program And a list display means for classifying programs based on the current time and displaying a list of recorded programs for each classified program.

  According to the present invention, only new recorded programs whose expiration date is after the current time are displayed as a normal program list, and only recorded programs whose expiration date is permanently stored are displayed as a permanently stored program list. It becomes easy for the user to find a recorded program to be played.

  In addition, according to the present invention, only a recorded program stored in the hard disk for the purpose of dubbing to a second recording medium removable from the apparatus such as a DVD-R for long-term storage is displayed as a list of permanently stored programs. Therefore, the user can easily determine the permanently stored program.

  Further, according to the present invention, since a user is informed when a program for permanent storage is stored in a necessary and sufficient capacity in the HDD, the user can perform an operation of dubbing a recorded program onto a second recording medium such as a DVD-R. You can do it efficiently.

<Example of recorded management data and expiration date initial value table of recording / playback apparatus>
Next, an example of the recorded program management data 207 and the expiration date initial value table 20 of the recording / playback apparatus according to the embodiment of the present invention will be described with reference to FIGS. FIG. 2 is a diagram showing an example of a recorded program table stored as recorded program management data of the recording / playback apparatus according to the embodiment of the present invention, and FIG. 3 is a diagram of the recording / playback apparatus according to the embodiment of the present invention. FIG. 4 is a diagram showing an example of a capacity table stored as recorded program management data, and FIG. 4 is a diagram showing an example of an expiration date initial value table of the recording / playback apparatus according to an embodiment of the present invention.

  In FIG. 2, the recorded program table 207a stores information relating to recorded programs. For example, information on recording date, channel, start time, recording time, program name, image quality, video data name, capacity, and expiration date is stored. Stored. In the expiration date information, the date and time until the recorded program is no longer worth saving is set. In this embodiment, the recorded programs are grouped based on the expiration date information. The recorded program is managed.

  In FIG. 3, the capacity table 207b stores information related to the total capacity of recorded data of recorded programs. For example, the automatic deletion target recording data capacity and the permanent storage target grouped according to the expiration date information. The total capacity of the recording data capacity and other normal recording data capacity is stored.

  In FIG. 4, the expiration date initial value table 20 stores information on the expiration date set as an initial value when a program is reserved. For example, a combination of words and phrases included in a continuous reservation and a program name The expiration date by is stored.

  Here, the term of validity is not necessarily saved in the main storage medium HDD103 because the value of viewing from the group A, which is worth the viewing of the recorded program and needs to be saved in the main storage medium HDD103, is low. It is defined as the date and time to be changed to the group B that may not be set.

  In addition, the term “permanent storage” means that the expiration date is not reached indefinitely, that is, it belongs to the group C in which the value of viewing the recorded program is always maintained and stored in the main storage medium HDD103. It is defined as letting

<Operation and display example of recording / playback apparatus>
Next, the operation and display example of the recording / playback apparatus according to an embodiment of the present invention will be described with reference to FIGS. FIG. 5 is a flowchart showing the operation of the recording / playback apparatus according to the embodiment of the present invention, FIG. 6 is a flowchart showing the operation of the automatic erasure processing routine of the recording / playback apparatus according to the embodiment of the present invention, and FIG. FIG. 8 is a flowchart showing the operation of the recording reservation processing routine of the recording / playback apparatus according to the embodiment of the present invention. FIG. 8 is a flowchart showing the operation of the list display processing routine of the recording / playback apparatus according to the embodiment of the present invention. 9 is a flowchart showing the operation of the expiration date changing process routine of the recording / playback apparatus according to the embodiment of the present invention, and FIGS. 10 to 19 are screen displays during operation of the recording / playback apparatus according to the embodiment of the present invention. It is a figure which shows an example.

  First, the CPU 112 determines whether or not the initial setting has not been completed after purchase. If the initial setting has not been completed, the CPU 112 executes an initial processing routine.

  In this initial processing routine, the CPU 112 displays, for example, a date and time setting screen for setting date and time on the monitor 102, and the user sets the current date and time on the screen. The CPU 112 writes the date and time set by the user in the RTC 116. Next, the CPU 112 displays a capacity setting screen for setting information on the storage limit capacity 202 a of the automatic erasure target recording data and the notification setting capacity 202 b of the permanent storage target recording data, and is stored in the set capacity value 202. The initial values of the storage limit capacity 202a of the automatic erasure target recording data and the notification setting capacity 202b of the permanent storage target recording data are displayed.

  It should be noted that the storage limit capacity 202a for the automatic erasure target recording data and the notification setting capacity 202b for the permanent storage target recording data do not have an initial value as a fixed value as a recording / playback device, but are set by the user at the initial setting by the user. It may be.

  The CPU 112 does not change these capacity values on the capacity setting screen. For example, when the user selects “decision”, the initial value is changed. When the user changes and selects “decision”, the changed capacity is obtained. The value is written as the set capacity value 202 (202a, 202b).

  The setting value of the notification setting capacity 202b of the recording data to be permanently stored is preferably set to about 2 to 4 times the capacity of the second recording medium that can be attached to and detached from the apparatus such as a DVD-R, from the viewpoint of user convenience. . Here, it is assumed that 120 GB is set as the storage limit capacity 202a of the automatic erasure target recording data, and 20 GB is set as the notification setting capacity 202b of the permanent storage target recording data. This process is performed by the capacity setting means 201.

  Next, in accordance with an instruction from the user, the CPU 112 performs initial settings such as a television broadcast reception area, a reception channel, and an electronic program guide reception channel, and ends the initial processing routine.

  Then, after the processing of the initial routine is completed, normal processing is performed. As shown in FIG. 5, first, the CPU 112 executes an automatic erasing processing routine (step S1), and then the CPU 112 is turned on. It is determined whether it is by the user or by the RTC 116 (step S2). When the power is turned on by the RTC 116, the recording processing routine is executed (step S3), and the processing is terminated when the recording processing routine is completed.

  When the user powers on in step S2, a menu screen as shown in FIG. 10 is displayed (step S4). Then, on the menu screen as shown in FIG. 10, an operation process by the user from the menu screen is performed (step S5).

  In the example shown in FIG. 10, the recording reservation processing routine is executed when “recording reservation” is instructed, the program list display routine is executed when “program list” is instructed, and “TV” is instructed. When the “auxiliary function” is instructed, the video data recorded on the main recording medium HDD 103 is transferred to the second recording medium (DVD-). R) and other various auxiliary processes such as a dubbing process are performed. When “Power off” is instructed, the apparatus is turned off to put the apparatus in a standby state and the process is terminated.

  Next, the operation of the automatic erasure processing routine in step S1 in FIG. 5 will be described.

  In the automatic deletion process routine, as shown in FIG. 6, first, the capacity table 207b in the recorded program management data 207 area shown in FIG. 1 is calculated and updated (step S41). Specifically, in step S41, the total capacity of the recorded programs whose expiration date is earlier than the current time is calculated as the automatically deleted target recording data capacity 301 in the capacity table 207b, and the recorded program whose expiration date is “permanent storage”. Is calculated as the permanent storage target recording data capacity 302, and the total capacity of the recorded programs whose expiration date is after the current time is calculated as the other normal recording data capacity 303.

  In the next step S42, it is determined whether or not the automatic erasure target recording data capacity 301 has exceeded the storage limit capacity 202a of the automatic erasure target recording data. If not, nothing is done and the process proceeds to step S45. In this case, after deleting the oldest program from the recorded program table 207a and deleting the corresponding video data from the recorded program video data 208 (step S43), the automatic deletion target recording data capacity 301 is recalculated ( Step S44) and the process returns to Step S42.

  In the next step S45, it is determined whether or not the permanent storage target recording data capacity 302 has exceeded the notification setting capacity 202b of the permanent storage target recording data. If not, the automatic erasure processing routine is terminated. Displays an alarm screen as shown in FIG. 11, for example (step S46). In the next step S47 and step S48, the CPU 112 waits until the user instructs “hold” or “dubbing” on the alarm screen. If the user instructs “hold”, the CPU 112 ends the automatic deletion processing routine. When “dubbing” is instructed, after the dubbing process (step S49) is performed on the permanently stored target recording data recorded on the main recording medium HDD103 to the second recording medium (DVD-R, etc.), the automatic erasing process is performed. End the routine. Here, the processing of step S41, step S42, and step S45 is processed by the capacity determination means 209 of FIG. 1, the processing from step S42 to step S44 is processed by the automatic erasure means 210 of FIG. Processing is performed by the user notification means 211 of FIG.

  Next, the operation of the recording reservation processing routine according to the user instruction in step S5 in FIG. 5 will be described.

  In the recording reservation processing routine, as shown in FIG. 7, the CPU 112 displays a recording reservation screen as shown in FIG. 12 (step S81), and the user uses the electronic program guide EPG (Electronic Program Guide) to reserve the program. Is input on the screen (step S82).

  Next, the CPU 112 refers to the expiration date column corresponding to the reserved program input by the user, and refers to the expiration date initial value table 20 stored in the main recording medium HDD 103, and is appropriate for the nature of the program to be recorded. Set the initial expiration date.

  When the expiration date is changed to a value other than the initial value due to the user's preference or lifestyle habits for the reserved program, the user inputs on the screen (step S83).

  Next, the CPU 112 determines whether or not the “CANCEL” button has been pressed (step S84). If pressed, the CPU 112 ends the recording reservation process and returns to the menu screen display. If not, the process of step S85 is performed. Move on. In step S85, the CPU 112 determines whether or not the “reserve” button has been pressed. If not, the process returns to step S84, and if it is pressed, the screen information is saved as the recording reservation data 205 ( Step S86), the recording reservation process is terminated, and the screen returns to the menu screen display.

  Here, it is assumed that the program illustrated in FIG. 12 is reserved for recording and an expiration date is set. The series of processing flow shown in FIG. 7 is processed by the recording reservation setting unit 203 in FIG. 1, and the processing in step S83 is processed by the expiration date setting unit 204 in FIG.

  Here, the expiration date initial value table 20 is for setting an initial value of an appropriate expiration date according to the nature of the program reserved for recording, which is a feature of the present embodiment. In this table, a daily continuous reserved program in which the word “weather forecast” or “news” is included in the program name of the electronic program guide EPG is worth watching even if it has not been viewed for two days after recording. Since it almost disappears, the expiration date is defined as “2 days later”.

  In addition, there are users who have a habit of watching daily scheduled reservation programs and weekly scheduled reservation programs that include the phrase “continuous drama” in the program name, so the expiration date is “8 days later”. Is defined. Furthermore, since other single-programmed reserved programs that are not continuously reserved will be almost viewable within half a month, the expiration date is defined as “15 days later”.

  This expiration date initial value table 20 may be fixedly set in the recording / playback apparatus 1 or the user uses a setting screen (not shown) during initial processing of the recording / playback apparatus 1 to reserve the preference of the reserved program. You may make initial settings according to your lifestyle and lifestyle.

  Next, the recording operation of the scheduled recording program will be described.

  The recording start time of the program is managed by recording time management means (not shown), and is managed by the RTC 116 so that the recording / playback apparatus 1 is powered on several minutes before the recording start time. When the recording / playback apparatus 1 is turned on by the RTC 116 a few minutes before the recording start time, the CPU 112 executes the automatic erasure processing routine (step S1) as described above in the operation of the main processing, and then in step S2. If it is determined, the process proceeds to the recording process routine (step S3).

  In the recording process routine (step S3), the CPU 112 first confirms the recorded program with the recording reservation data 205 and waits until the recording start time comes. Thereafter, when the recording start time comes, the CPU 112 records the video data of the program and records it in the area of the recorded program video data 208.

  Next, the CPU 112 calculates a specific expiration date and records the recorded program in the area of the recorded program management data 207 in the format of the recorded program table 207a.

  Then, the power is turned off to put the apparatus in a standby state, and the recording processing routine is ended. A series of these processing flows is processed by the recording execution means 206 of FIG.

  The contents of the recorded program table 207a shown in FIG. 2 are recorded on the recording / playback apparatus 1 from 14:37 on July 4, 2004 (Sunday) according to the scheduled recording data 205 in FIG. The content after operating until 19:41 is shown. The calculated expiration date is stored in the expiration date column of the recorded program table 207a. That is, “permanent storage” is stored as the “permanent storage” program in FIG. 12, and “n days later” is stored as the “date and time after recording date” expiration date in the program set as “n days later”. The

  Next, the operation of the program list display processing routine according to the user instruction in step S5 in FIG. 5 will be described.

  In the program list display processing routine, as shown in FIG. 8, first, a recorded program is extracted from the recorded program table 207a and a program list is displayed (step S91).

  In step S91, in the first screen display, the normal program list shown in FIG. 13 is displayed. Thereafter, when the user selects a tab on the screen, the CPU 112 selects a “normal” program that becomes “group A that needs to be stored in the main storage medium HDD” shown in FIG. 13 according to the selected tab. List, “Permanent Storage” program list that becomes “Group C to be kept in the main storage medium HDD” shown in FIG. 14, “Group B not necessarily saved in the HDD” shown in FIG. "After the deadline" program list, and "All" program list "Group A, B, C" shown in FIG.

  The relationship between the tab selected by the user, the program list name to be displayed, and the program display conditions is shown in steps S91a to S91d in FIG.

  This step S91 is processed by the list display means 212 of FIG.

  In the “normal” program list shown in FIG. 13 in step S91, only the minimum number of recorded programs whose expiration date is after the current time out of the enormous number of recorded programs recorded on the main recording medium HDD 103 is the expiration date. Are displayed in ascending order of date and time, so that the user can easily find the program he / she wants to watch at the beginning of the program list.

  In the “permanent storage” program list shown in FIG. 14, only recorded programs stored in the main recording medium HDD 103 for the purpose of dubbing to the second recording medium 104 that can be attached to and detached from the apparatus such as a DVD-R are displayed. Therefore, the user can easily determine the program.

  In the list of programs after “expiration date” shown in FIG. 15, recorded programs whose expiration date is earlier than the current time are displayed in descending order of the expiration date and time, so that the user can view the program within the expiration date. Even if it is not, the user can easily find the program he / she wants to play at the beginning of the program list.

  FIG. 17 shows a screen in a state where the user has selected a magic show program with a recording date of 7/20 on the normal program list screen shown in FIG. The program selected by the user is displayed in reverse video. When the “change” button is pressed on the screen of FIG. 17, the CPU 112 executes an expiration date changing process routine for the selected program. When the “play” button is pressed, the CPU 112 selects the selected program. When the “return” button is pressed, the program screen display process routine is terminated.

  Next, the operation of the expiration date changing process routine when the “change” button is pressed on the screen of FIG. 17 will be described.

  In the expiration date changing process routine, first, as shown in FIG. 9, the CPU 112 displays the expiration date changing screen shown in FIG. 18 for the selected program (step S211). Thereafter, for example, when the program of the magic show on the recording date 7/20 is changed to “permanent storage”, the user sets the changed expiration date as “permanent storage” on the screen shown in FIG.

  In the next step S212, the CPU 112 determines whether or not the “Cancel” button has been pressed. If it has been pressed, the process proceeds to step S215. If not, the process proceeds to step S213. In step S213, the CPU 112 determines whether or not the “OK” button has been pressed. If not, the CPU 112 returns to step S212. If it has been pressed, the CPU 112 changes the expiration date of the program in the recorded program table 207a (step S213). S214), the program list is displayed again (step S215), and the expiration date changing process routine is terminated.

  The series of processing flow shown in FIG. 18 is performed by the expiration date changing means 213 in FIG.

  Next, the operation of the program playback processing routine when the “play” button is pressed on the screen of FIG. 17 will be described.

  In the program playback processing routine, first, the CPU 112 plays back the recorded program selected by the user. Next, the CPU 112 waits until the recorded program is played back to the end or the playback is interrupted by the user operation. When the recorded program is played back to the end or the playback is interrupted by the user operation, The program playback process ends.

  In this playback processing routine, when the recorded program is played back to the end or when playback is interrupted by a user operation, for example, a confirmation screen shown in FIG. 19 is displayed, and the expiration date is displayed to the user by the confirmation screen. You may be made to confirm whether to change.

  As the operation on the confirmation screen shown in FIG. 19, if the “No” button is pressed, the reproduction process is terminated, and if the “Yes” button is pressed, the expiration date changing process routine shown in FIG. 9 is executed. To do.

  As a result, if the program is played to the end, it is highly likely that the program will be changed to permanent storage depending on the contents of the program, and if the playback is interrupted in the middle, the expiration date should be shortened so that it can be deleted Since the program is highly likely to be a program, the user can easily change the expiration date on this confirmation screen.

  As described above, in this embodiment, an expiration date is set for each program to be recorded, and “standard”, “after expiration”, and “permanent storage” are based on the expiration date based on the current time. Are grouped into group A, group B, and group C, and the list of recorded programs is displayed. Group A, B, and C are classified based on the current time on the time axis. The group to which the recorded program belongs is automatically changed as time passes, and the user does not have to change the group.

  Furthermore, as a list of normal recorded programs to be shown to the user as a standard, the list of recorded programs belonging to Group A is displayed in ascending order of the expiration date and time, so it is limited to recorded programs that continue to be worth watching. The recorded program list is displayed in the order in which the expiration date expires, and the essential program that the user wants to watch is displayed at the beginning of the normal recorded program list, making it easy to find.

  In addition, as a list of recorded programs after the expiration date to be shown to the user, the recorded programs belonging to group B are displayed in descending order of the expiration date and time, so the recorded program list is displayed in order of late expiration date. In the unlikely event that the essential program that the user wants to watch cannot be viewed within the expiration date, the essential program that the user wants to view is displayed at the beginning of the list of recorded programs after the expiration date, It becomes easy to search.

  In addition, since the program is scheduled for recording, an appropriate expiration date (for example, two days in the case of weather forecasts and news programs) is set for each scheduled program. Even if it is a program that has been recorded, since only the recorded program with the elapsed time from the recording date less than 2 days belongs to the group A, the number of programs displayed in the normal recorded program list to be shown to the user as a standard is required The minimum number makes it easier for users to find the programs they want to watch.

  In addition, it is configured to display only recorded programs whose expiration date is permanently stored as a list of recorded programs that are permanently stored, and to notify the user when the capacity of the program exceeds a certain set capacity. Therefore, a list of recorded programs of the group C, which is always worth watching and is always stored in the HDD, is displayed, and the user can be notified when a certain amount of such programs are stored.

  As mentioned above, the invention made by the present inventor has been specifically described based on the embodiment. However, the present invention is not limited to the embodiment, and various modifications can be made without departing from the scope of the invention. Needless to say.

  For example, in the present embodiment, the recorded program is “normal” that is “group A that needs to be stored in the HDD”, and “group B that is not necessarily stored in the HDD”. In order to display a list of programs in “Permanent storage”, which is “Group C to be stored all the time in the HDD”, and to display a list of programs, the comparison was made between the expiration date of the recorded program and the current time. The configuration is not limited to the configuration, and a recorded program may be provided with codes and attributes corresponding to the groups A, B, and C, and the program list may be displayed according to the codes and attributes.

  In the present embodiment, the tuner 105 is built in the recording / playback apparatus 1. However, the tuner 105 may have a configuration external to the recording / playback apparatus 1.

  In the present embodiment, the recording / playback apparatus 1 includes the second recording medium 104. However, the second recording medium 104 may be externally attached to the recording / playback apparatus 1. Further, the second recording medium 104 may not be configured.

  The present invention can be used not only for a so-called HDD built-in DVD recorder but also for an external TV tuner or a built-in TV personal computer.
