A recording reservation list 218 is created on the basis of the information recorded in.
[0018]
As shown in FIG. 3, the remote controller 113 includes a numeric button 301, an arrow button 302, a decision button 303, a user authentication button 304, a recorded program list display button 305, a recording reservation list display button 306, and a recording A button 307, a play button 308, and a stop button 309 are provided. The user inputs an operation to the video recording / playback apparatus using these buttons, and the remote controller 113 outputs it as an operation signal. The video recording / playback apparatus receives the operation signal using the remote control receiver 112 and processes the operation input from the user.
[0019]
The user information recording unit 212 records user information for identifying individual users. User information is unique to each user. FIG. 4 shows the configuration of user information. The user information includes a user ID 401 and a password 402. A user ID 401 included in the user information is an integer for identifying the user and has a unique value for each user. The user authentication processing unit 201 performs user authentication processing using this user information, and an unauthenticated user cannot use the video recording / playback apparatus. The user needs to register his / her user information in the video recording / playback apparatus in advance.
[0020]
When the value of the user ID 401 is 0, it indicates that the user does not exist and is not used as a value for identifying an actual user. The same applies to other IDs described later.
[0021]
User authentication processing will be described. When the user turns on the video recording / playback apparatus or presses the user authentication button 304 provided on the remote controller 113, the user authentication processing unit 201 displays a user authentication screen on the display 114. FIG. 5 shows an example of a user authentication screen. The user authentication screen is provided with a user ID input form and a password input form. The user inputs a user ID 401 and a password 402 using the remote controller 113. When the input by the user is completed, the user authentication processing unit 201 starts a user authentication process. FIG. 6 shows a flowchart of the user authentication process. First, the user authentication processing unit 201 searches whether user information having a user ID 401 that matches the user ID 401 input by the user is recorded in the user information recording unit 211 (S101). If the corresponding user information is found, the process proceeds to the next step (S102), and if not found, the user authentication process is considered to have failed and the process ends. In step S102, it is confirmed whether or not the input password matches the password included in the corresponding user information. If they match, the user is authenticated and the user authentication process ends, and if they do not match, the user authentication process is considered to have failed and the process ends. The authenticated user is subsequently identified by the user ID 401.
[0022]
An authenticated user is given a recorded program list 217 and a recording reservation list 218 dedicated to the user. In the recorded program list 217, only information related to the programs that can be played back by the user among the recorded programs recorded in the HDD 107 is displayed, and in the recording reservation list 218, only information related to the recording reservation set by the user is displayed. The Information necessary for creating the recorded program list 217 is recorded in the recorded program list recording unit 213 provided in the flash memory 115, and information necessary for creating the scheduled recording list 218 is stored in the flash memory 115. Is recorded in the recording reservation list recording unit 215 provided in The recorded program list recording unit 213 is given a dedicated area for each user. The same applies to the recording reservation list recording unit 215. The recorded program list recording unit 213 and the recording reservation list recording unit 215 have been described as being provided in the flash memory 115, but may be a ROM or a RAM as long as the information can be stored. It may be provided. Further, although the ROM 110 and the flash memory 115 are configured separately, they may be configured as a single unit.
[0023]
Hereinafter, recording processing and playback processing in the embodiment of the present invention will be described, and sharing processing, deletion processing, dubbing processing, and editing processing will be described in order as functions for handling a recorded program.
[0024]
First, the recording process will be described. When the user presses the recording button 307, the recording processing unit 204 starts the recording process. FIG. 7 shows a flowchart of the recording process. Hereinafter, a user who has performed a recording operation is referred to as a recording operation user. First, the recording processing means 204 creates recorded program list registration information. FIG. 8 shows the configuration of the recorded program list registration information. The recording operation user ID 801 is written in the recording program list registration information as the recording operation user ID 801, the recording operation time 802 is the recording operation start time, and an integer for identifying the recording program to be recorded in the HDD is recorded in the recorded program list registration information. The recorded program list registration information is recorded in the recorded program list recording unit 213 of the recording operation user (S201). In addition to this, the recorded program list registration information includes a sharing operation user ID 803, a last access time 804, and an editing information ID 806. Here, the sharing operation user ID is 0, and the last access time is the recording operation time. 0 is written in the edit information ID at the same time. These will be described later.
[0025]
Further, the recorded program list management information shown in FIG. 9 is created, the same value as the recorded program ID 805 written in the recorded program list registration information is written in the recorded program ID 901, and the user ID 401 of the recording operation user is recorded in the recorded program owning user ID list 902. Are recorded in the recorded program list management information recording unit 214 (S202). Thereafter, the recording processing means 204 converts the analog video / audio signal of the TV channel received by the TV tuner 102 into a digital video / audio signal by the A / D converter 103 (S203), and the digital video / audio signal is converted into an MPEG-2 encoder. The information is converted into compressed information in the MPEG-2 format by 104 (S204).
The compressed information is recorded in the HDD 107 as a recorded program (S205). This operation is repeated until the recording operation user presses the stop button 309 (S206). When the stop button 309 is pressed, the recording processing unit 204 ends the recording process.
[0026]
The recording reservation setting process will be described. When the recording reservation list display button 306 is pressed by the user, the recording reservation list display processing unit 203 creates the recording reservation list 218 for the user and displays the recording reservation list screen on the display 114. FIG. 10 shows an example of the recording reservation list screen. Each row of the recording reservation list 218 describes the time for starting the recording reservation, the time for ending the recording reservation, and the TV channel for recording. When the user selects a new reservation row using the remote controller 113 and presses the enter button, a recording reservation setting screen is displayed on the display. While watching this, the user inputs the start time and end time of the recording reservation and the TV channel to be recorded using the remote controller 113. When the user completes input of each item on the recording reservation setting screen, the recording reservation setting processing unit 205 starts the reserved recording setting process.
[0027]
A flowchart of the recording reservation setting process is shown in FIG. Hereinafter, a user who has performed a recording reservation operation is referred to as a recording reservation user. First, the recording reservation setting processing unit 205 newly creates recording reservation information. FIG. 12 shows the configuration of the recording reservation information. An integer for identifying the recording reservation is written in the recording reservation information as a recording reservation ID 1201, a recording reservation start time input by the recording reservation user as a start time 1202, an end time as an end time 1203, and a TV channel to be recorded as a TV channel 1204. Then, the user ID 401 of the recording reservation user is written at the head of the recording reservation user ID list 1205 (S301). In the recording reservation information recording unit 216, recording reservation information related to a recording reservation that has been set so far and has not yet been executed is recorded. The recording reservation setting processing means 205 confirms whether or not the execution time of the recording reservation information recorded in the recording reservation information recording unit 216 overlaps with that of the recording reservation information newly set by the recording reservation user. (S302).
[0028]
If there is an overlap, a message indicating that the recording reservation cannot be set is displayed on the display 114 to the recording reservation user, and the recording reservation information is discarded (S305). Thereafter, the recording reservation setting process is terminated. If there is no overlap, the recording reservation information is recorded in the recording reservation information recording unit 216, and the process proceeds to the next step (S304) (S303). However, even if there is an overlap, if the start time 1202 and the end time 1203 coincide with each other and the TV channel 1204 is the same, it is interpreted as recording reservation information for the same TV program. In this case, the recording reservation processing information is discarded, and the user ID 401 of the recording operation user is added to the recording reservation user ID list 1205 of the recording reservation information recorded in the recording reservation information recording unit. Transition is made (S306, S307).
[0029]
In step S304, recording reservation list registration information is newly created. FIG. 13 shows the configuration of the recording reservation list registration information. The same value as the recording reservation ID 1201 written in the recording reservation ID 1303 is written in the recording reservation list registration information as the recording reservation user ID 1301 as the user ID of the recording reservation user, the current recording time as the reservation recording time 1302, and the recording reservation information. This recording reservation list registration information is recorded in the recording reservation list recording unit 215 of the recording reservation user, and the recording reservation setting process is terminated.
[0030]
The recording reservation execution process will be described. The recording reservation execution processing means 206 monitors the recording reservation information recorded in the recording reservation information recording unit 216, and starts the recording reservation execution process when it detects that the start time 1202 coincides with the current time. FIG. 14 shows a flowchart of the recording reservation execution process. First, the recording reservation information is read, and the user indicated by the user ID 401 recorded at the top of the recording reservation user ID list 1205 is set as a recording reservation user (S401, S402). The recording reservation list registration information corresponding to the recording reservation information is read from the recording reservation list recording unit 215 of the recording reservation user (S403). Recording program list registration information is newly created, recording reservation user ID is written in recording operation user ID 801, recording reservation time 1302 is written in recording operation time 802, and this recording program list registration information is recorded in the recording program list of the recording reservation user. Then, the read recording reservation list registration information is deleted from the recording reservation list recording unit 215 (S404, S405). When a plurality of user IDs 401 are recorded in the recording reservation user ID list 1205 included in the recording reservation information, the same processing is performed for all the users indicated by them (S406, S409). Thereafter, a recording process is executed and recorded as a recorded program in the HDD 107 in the same manner as normal recording (S407). When the recording process ends, the corresponding recording reservation information is deleted from the recording reservation information recording unit 216, and the recording reservation execution process ends (S408).
[0031]
The recording reservation list display process will be described. When the recording reservation list display button 306 is pressed by the user, the recording reservation list display processing unit 203 starts a recording reservation list display process. FIG. 15 shows a flowchart of the recording reservation list display process. The recording reservation list display processing means reads all the recording reservation list registration information from the recording reservation list recording unit 215 of the user, and creates the recording reservation list 218 based on them (S501, S502). This is displayed on the display 114, and the recording reservation list display process is terminated (S503).
[0032]
The recorded program list display process will be described. When the user presses the recorded program list display button 305, the recorded program list display processing means 202 starts a recorded program list display process. FIG. 16 shows a flowchart of the recorded program list display process. The recorded program list display processing means reads all recorded program list registration information from the recorded program list recording unit 213 of the user, and creates a recorded program list 217 based on them (S601, S602). This is displayed on the display 114, and the recorded program list display process is terminated (S603).
[0033]
Each line of the recorded program list displays the title of the recorded program, the date and time when the recorded program was recorded, and the user name corresponding to the user who performed the recording operation. FIG. 17 shows an example of a recorded program list screen. The user selects a recorded program to be played back using the remote controller 113 and instructs the start of playback when the playback button is pressed. When the playback button is pressed, the playback processing means 207 starts playback processing.
[0034]
Next, the reproduction process will be described. FIG. 18 shows a flowchart of the reproduction process.
First, the reproduction processing means records the current time at the last access time 804 of the recorded program list registration information corresponding to the recorded program, which is recorded in the recorded program list recording unit 213 of the user who executed the reproduction process (S701). ). Thereafter, the corresponding recorded program recorded as compressed information in the MPEG-2 format is read from the HDD 107, and the compressed information is expanded into a digital video / audio signal using the MPEG-2 decoder 105 (S702). The digital video / audio signal is converted into an analog signal using the D / A converter 106 (S703), and the analog video / audio signal is drawn and displayed on the display 114 (S704). The processes from step S701 to step S704 are repeated until the user presses the stop button 309 or the corresponding recorded program is reproduced to the end (S705, S706). When either one of these conditions is satisfied, the reproduction processing means ends the reproduction process.
[0035]
Since only the information recorded in the recorded program list recording unit 213 of the currently authenticated user is displayed in the recorded program list 217, in principle, the user has recorded a recorded program recorded by another user in the HDD 107. But I can't know its existence. On the other hand, since the existence of a recorded program that the user has recorded is not known from other users, the user's playbasis is protected with respect to the recorded program. In addition, it is possible to prevent playback or deletion without permission.
[0036]
However, this alone is inconvenient when a recorded program that does not require protection, for example, when a user wants other users to watch a recorded program. Therefore, the present invention provides a mechanism that allows a recorded program recorded by a user to be shared with other users.
[0037]
The sharing process will be described. When the user selects a recorded program to be shared with other users from the recorded program list 217 using the remote controller 113 and presses the enter button 303, the menu shown in FIG. 19 is displayed on the display. When sharing 1901 is selected from the menu items, a message asking a user who wants to permit sharing of the recorded program is displayed on the display 114. The user selects some of the users other than himself and presses the enter button 303. When the determination button 303 is pressed here, the sharing processing unit 208 starts sharing processing. FIG. 20 shows a flowchart of the sharing process. Hereinafter, the user who has executed the sharing process will be referred to as a sharing operation user, and the recorded program for which sharing is set will be referred to as a shared recorded program.
[0038]
First, the sharing processing unit 208 reads recorded program list registration information corresponding to the recorded program from the recorded program list recording unit 213 of the sharing operation user (S801). It is confirmed whether or not the recording operation user ID 801 included in the recorded program list registration information matches the user ID 401 of the sharing operation user (S802). If they do not match, it is determined that the sharing operation user is not the user who performed the recording operation of the corresponding program, and the sharing process ends. By doing so, only the user who performed the recording operation can perform the sharing operation, and it becomes impossible for other users to set the shared recording program without permission. If they match, the sharing operation user ID 401 is written in the sharing operation user ID 803 of the recorded program list registration information, and the current time is written in the last access time 804, which is overwritten and recorded in the recording program list recording unit 213 of the sharing operation user (S803). , S804). The recorded program list registration information is duplicated and recorded in the recorded program list recording unit 213 of all users who are permitted to share the recorded program (S805). Further, the user ID 401 (shared user ID) of all users who are allowed to share is added to the recorded program owning user ID list 902 included in the recorded program list management information corresponding to the recorded program, and the sharing process is terminated. (S806).
[0039]
The recorded program list registration information corresponding to the recorded program is recorded not only in the recorded program list recording unit 213 of the recording operation user but also in the recorded program list recording unit 213 of the user permitted to share. Therefore, the recorded program list display process 202 also displays them on the recorded program list of those users. The user can operate the shared recording program in the same manner as the non-shared recording program, and the playback process 207 can play back the same.
[0040]
When the shared operation user ID 803 included in the recorded program list registration information is 0, the corresponding recorded program is a non-shared recorded program, and when it is not 0, it is a shared recorded program. Thereafter, the sharing operation user ID 803 is used to determine whether the program is a shared recording program.
[0041]
Since the non-shared recorded program is displayed only in the recorded program list 217 of the recording operation user, other users cannot delete the non-shared recorded program, and there is no need to consider the deletion. Since the shared recorded program is displayed in the recorded program list 217 of all users permitted to share, it is necessary to allow the user permitted to share to be deleted. However, if all the shared users can freely delete the shared recorded program, if the shared recorded program is played back, it has already been deleted from the HDD 107 by another user and cannot be played back. There is also a possibility. This situation must be prevented. The same can be said for editing and dubbing.
[0042]
Deletion processing in the present invention will be described. When the user selects a recorded program to be deleted from the recorded program list 217, selects a delete 1902 from the menu and presses the enter button 303, the delete processing unit 209 starts the delete process. FIG. 21 shows a flowchart of the deletion process. Hereinafter, the user who has performed the deletion operation is referred to as a deletion operation user.
[0043]
First, the recorded program list registration information is deleted from the recorded program list recording unit 213 of the deletion operation user (S901). Thereafter, the deletion processing means deletes the user ID 401 of the deletion operation user from the recorded program owning user ID list 902 included in the recorded program list management information corresponding to the corresponding recorded program, and another user ID 401 is added to the recorded program owning user ID list 902. Is checked (S902, S903). Only when no other user ID 401 is recorded, the corresponding recorded program is deleted from the HDD 107, and the corresponding recorded program list management information is deleted from the recorded program list management information recording unit 214 (S904, S905). Thereafter, the deletion process is terminated.
By doing so, the recorded program is deleted from the HDD 107 only after it is deleted from the recorded program list 217 of all users.
[0044]
If a recorded program that is allowed to be shared by another user is not of interest to the user, the user feels that it is cumbersome to delete the shared recorded program, and deletes the shared recorded program. It is possible to leave it without doing it. In such a situation, the recorded program list 217 of the user becomes complicated, and since the user does not execute the deletion process, the corresponding recorded program is not deleted from the HDD 107 indefinitely.
[0045]
In order to prevent such a situation, the deletion processing unit 209 searches the user's recorded program list 217 for recorded programs that have not been played, dubbed, or edited by the user for a predetermined period. If found, the recorded program is regarded as having no interest for the user, and the recorded program list registration information corresponding to the recorded program is deleted from the recorded program list recording unit 213 of the user. At this time, the last access time 804 included in the recorded program list registration information is used to find out the corresponding recorded program.
[0046]
The dubbing process will be described. There are two types of dubbing methods: moving to delete a dubbing source recorded program after dubbing and copying without deleting. Further, there are an HDD 107 and a DVD-RAM drive 108 as recording devices that can be dubbing destinations and dubbing sources. These are specified by the user's operation. Also, some recorded programs are prohibited from being copied. If the recorded program of the dubbing source is copy-prohibited, only moving can be executed. The dubbing process considers the above.
[0047]
When the user selects a recorded program to be dubbed from the recorded program list 217, selects dubbing 1903 from the menu and presses the enter button 303, the dubbing processing means 210 starts the dubbing process. FIG. 22 shows a flowchart of the dubbing process when the corresponding recorded program is prohibited from being copied, and FIG. 23 shows a flowchart of the dubbing process when the recorded program is not prohibited from being copied. Hereinafter, the user who has performed the dubbing operation is referred to as a dubbing operation user.
[0048]
If the recorded program is prohibited from being copied, first, the dubbing processing unit 210 reads the recorded program list registration information corresponding to the recorded program from the recorded program list recording unit 213 of the dubbing operation user, and uses the recorded program list registration information as the recorded program list registration information. It is confirmed whether or not the recording operation user ID 801 included and the user ID 401 of the dubbing operation user match. If they do not match, the dubbing process is terminated. If they match, the recorded program management information corresponding to the recorded program is read from the recorded program list management information recording unit 214.

Next, a process for dubbing a recorded program when the recorded program is not copy-prohibited will be described. In this case, the recorded program dubbing processing means reads the recorded program from the dubbing source recording device and records it on the dubbing destination recording medium (S1101). Thereafter, the processing procedure changes depending on whether the dubbing destination recording device is the HDD 107 or the DVD-RAM drive 108 (S1102).
[0050]
A recorded program dubbing process when the dubbing destination recording apparatus is the HDD 107 will be described. In this case, new recorded program list registration information is created, the recording operation user ID 801 is the dubbing operation user ID 401, the recording operation time 802 and the last access time 804 are the current time, and the sharing operation user ID 803 is 0. An integer for identifying the recorded program dubbed in the HDD 107 is written in the program ID 805 and recorded in the recorded program list recording unit 213 of the dubbing operation user (S1103). Furthermore, the newly recorded program list management information is created, and the same value as the recorded program ID 901 is recorded in the recorded program ID 902 of the recorded program list registration information. The ID 401 is written and recorded in the recorded program list management information recording unit 214 (S1104). It is confirmed whether or not the dubbing method is duplication. Only when the dubbing method is duplication, the dubbing processing means 210 deletes the corresponding recorded program as the dubbing source from the DVD-RAM drive 108 (S1105, S1108). Thereafter, the dubbing process is terminated.
[0051]
A dubbing process when the dubbing destination recording apparatus is the DVD-RAM drive 108 will be described. In this case, it is confirmed whether the dubbing method is movement (S1106). Only in the case of movement, the corresponding recorded program as the dubbing source must be deleted from the HDD 107. At this time, the corresponding recorded program is deleted by the deletion processing means 209 in the same manner as the normal recorded program deletion process (S1107). Thereafter, the dubbing process is terminated.
[0052]
When the dubbing destination is the DVD-RAM drive 108 and the dubbing method is duplication, the duplication is from the HDD 107 to the DVD-RAM drive 108. At this time, the dubbing processing means 210 does nothing and ends the dubbing process as it is.
[0053]
The editing of the recorded program will be described. If the user can freely edit the shared recorded program, when one user plays the shared recorded program, it was edited by another user and the content was completely different. It can happen. In order to prevent this, in the editing process of the present invention, when editing a shared recorded program, the recorded program recorded in the HDD 107 is not directly edited, but the contents of the user's editing operation are recorded in the HDD 107 as editing information. To do.
[0054]
The editing process in the present invention will be described. When a recorded program to be edited is selected from the recorded program list 217, an edit 1904 is selected from the menu and the enter button 303 is pressed, the edit processing means 211 starts the editing process. FIG. 24 shows a flowchart of the editing process. Hereinafter, a user who has performed an editing operation is referred to as an editing operation user.

First, the recorded program list management information corresponding to the corresponding recorded program is read from the recorded program list management information recording unit 214, and it is confirmed whether or not the user ID 401 other than the editing operation user is recorded in the recorded program owning user ID list 902. (S1201, S1202). If not recorded, the corresponding recorded program is edited in accordance with the operation of the editing user and the editing process is terminated (S1205). If recorded, the editing information is created without directly editing the recorded program recorded in the HDD 107, the contents of the editing operation performed on the recorded program by the user are written and recorded in the HDD 107 ( S1203). Thereafter, the recorded program list registration information corresponding to the corresponding recorded program recorded in the recorded program list recording unit 213 of the editing user is read. An integer for identifying the editing information is written in the editing information ID 806, the recorded program list registration information is overwritten and recorded in the recorded program list recording unit 213 of the editing user, and the editing process ends (S1204).
[0056]
When the reproduction processing unit 207 reproduces a recorded program, if the editing information ID 806 included in the recorded program list registration information corresponding to the corresponding recorded program is not 0, the editing content recorded in the editing information indicated by the editing information ID 806 is added. Play the recorded program along the line. The same applies when the dubbing processing unit 210 performs dubbing. When deleting the recorded program list registration information, the deletion processing unit 209 also deletes the editing information indicated by the editing information ID 806 from the HDD 107 at the same time.
