Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a recording apparatus and method, a recording medium, and a program, and more particularly to a recording apparatus and method, a recording medium, and a program capable of reliably recording a reserved broadcast program.
[0002]
[Prior art]
When performing scheduled recording in a television receiver, channel numbers and broadcast times are mainly used to identify reserved programs. The television receiver receives and records the broadcast channel signal of the reserved program at the reserved broadcast time.
[0003]
[Problems to be solved by the invention]
By the way, in the stationary television receiver, if the channel number and the broadcast time are set at the time of recording reservation, the program reserved at the reserved broadcast time is broadcast unless the program broadcast time is changed. The program can be recorded reliably. However, in portable portable television receivers, the channel number on which the reserved program is broadcast may differ depending on the area after the move, because the broadcast tower to which the program is transmitted differs. When a portable television receiver moves beyond a prefecture, the broadcasting station that organizes the program is different, so the program that is scheduled to be recorded differs from the program that is actually recorded, and the user can select the desired program. There was a problem that could not be scheduled recording.
[0004]
The present invention has been made in view of such a situation, and makes it possible to reliably record a reserved program even when a portable television receiver is moved.

The scheduled recording setting program 174 generates AV content for executing scheduled recording based on the setting. This AV content corresponds to the setting (recording time and recording mode for determining image quality), and reserves a storage area of the HDD 158 in advance.
[0087]
The reservation monitoring program 175 always operates (so-called resident) when the portable television receiver 1 is operating (when the OS is operating), and the reservation recording program 174 generates Scheduled recording is executed based on the AV content to be recorded and the time supplied from the clock 132. In addition, the reservation monitoring program 175 changes the setting of AV content for executing reservation recording.
[0088]
The reception program 176 supplies the program ID obtained from the program information server 111 to the recording / playback program 171 via the public line 101 and the Internet 102 from the communication unit 66.
[0089]
For example, the reception program 176 may be executed by an unillustrated I / O (Input / Output) controller including an embedded computer that is operating even in the sleep mode.
[0090]
Next, with reference to FIG. 12, the recording reservation processing of the program by the reserved recording setting program 174 will be described.
[0091]
In step S11, based on the input from the user, the scheduled recording setting program 174 acquires the broadcast start time and recording time of the program. The recording time represents the time for actually recording a program desired by the user, but may be broadcast time (time for broadcasting the program).
[0092]
In step S12, based on the input from the user, the scheduled recording setting program 174 acquires the broadcast channel of the program.
[0093]
In step S13, the scheduled recording setting program 174 acquires current position information. The current position information is acquired from the extension module 11 attached to the portable television receiver 1 via the module interface (I / F) 54.
[0094]
In step S <b> 14, the reserved recording setting program 174 stores the program broadcast start time, recording time, broadcast channel, and current position information in the reservation database 62.
[0095]
In step S15, the timer recording setting program 174 accesses the program information server 111 from the communication unit 66 via the public line 101 and the Internet 102, and starts the broadcast channel and broadcast acquired in the processes of steps S11, S12, and S13. The time and current position information (further broadcast time if necessary) are transmitted, and a search for the corresponding program ID is requested. Based on this request, the program information server 111 refers to the registration list shown in FIG. 8 and searches for the channel number of the broadcast channel in the area including the current location and the program ID of the program broadcast at the broadcast start time. To do.
[0096]
For example, when data of current location “a1”, channel number “6”, and broadcast start time “May 10, 2002 08:50:00” is transmitted, the current location “a1” is included in the region “A”. As a program ID of a program whose broadcast start time is “May 10, 2002, 08:50:00” in the channel “6” in the program broadcast in the region “A”, “0001 "Is searched.
[0097]
The program information server 111 transmits the searched program ID to the portable television receiver 1 via the Internet 102 and the public line 101. The scheduled recording setting program 174 stores this program ID in the reserved database 62 (FIG. 6).
[0098]
As described above, in the reservation database 62, as shown in FIG. 6, the channel number, recording time, broadcast start time, program ID, and current location (reserved location) of the program reserved by the user are registered.
[0099]
As described above, at the time of reservation, the user operates the display unit 2 to input the channel number, the broadcast start time, and the recording time. The input operation at this time will be further described with reference to FIG.
[0100]
When a reservation is instructed by the user, the scheduled recording setting program 174 causes the display unit 2 to display a reservation screen as shown in FIG. On this reservation screen, a recording reservation channel, broadcast start time, program contents, and the like are displayed.
[0101]
In the example of FIG. 13, the channel reserved for recording is “6”, and the broadcast start time is “05/10/2002 08:50:00”. In this example, it is further displayed that the title of the program is “morning news”. This title is transmitted from the program information server 111 together with the program ID.
[0102]
When the recording reservation window 211 is selected by the user and is active, the channel selection button 217 and the determination button 212 are active and can be operated. The channel selection button 217 is a button operated when selecting a channel of a program to be reserved for recording. When the determination button 212 is clicked, the input reservation information is confirmed.
[0103]
On the other hand, when the recording reservation window 211 is selected and active, the stop button 213, the playback button 214, and the pause button 215 are inactive, and the recording / playback program 171 is clicked on the playback button 214 or the pause button 215. Even it does not work.
[0104]
As will be described later with reference to FIG. 18, the program selection button 217 is a button for selecting a program to be reproduced when the recorded program is reproduced.
[0105]
Next, program recording processing by the recording / reproducing program 171 will be described with reference to FIG. This process is periodically performed at predetermined time intervals, for example, every 5 minutes or every 10 minutes.
[0106]
In step S21, the recording / playback program 171 determines whether or not there is a program reserved for recording in the reservation database 62 (FIG. 6). If there is no program reserved for recording, the recording process ends. To do.
[0107]
If it is determined in step S21 that there is a program reserved for recording, the process proceeds to step S22, and the recording / reproducing program 171 selects one program reserved for recording from the list in the reservation database 62.
[0108]
In step S23, the recording / reproducing program 171 reads the broadcast start time of the selected program recorded in the reservation database 62.
[0109]
In step S24, the recording / reproducing program 171 acquires the current time from the clock 132 of the extension module 11.
[0110]
In step S25, the recording / reproducing program 171 determines whether or not the difference between the current time acquired in step S24 and the broadcast start time read out in the process of step S23 is equal to or less than a predetermined time. If it is determined as follows, in step S26, the recording / reproducing program 171 controls the tuner 64 to receive the program of the designated channel, and causes the HDD 158 of the recording / reproducing unit 63 to record the program. At this time, when the program is not encoded, it is recorded after being encoded by the MPEG encoder 156, and when it is encoded, it is recorded as it is.
[0111]
The predetermined time is preset and stored in the Flash ROM 52 in advance. For example, consider the case where the predetermined time is set to 30 seconds. If the program ID “0001” in FIG. 6 is selected in step S22, the broadcast start time is “08:50:00 on May 10, 2002”, so the current time is “May 10, 2002”. When "08:49:30" is passed, the difference is determined to be equal to or less than the predetermined time in step S25, and the program is recorded in the recording / playback unit 63 in step S26. Of course, this time can also be set to 10 seconds, 15 seconds, or 20 seconds, for example.
[0112]
Next, in step S27, the recording / reproducing program 171 deletes the program recorded in the recording / reproducing unit 63 from the reservation list recorded in the reservation database 62 (turns on the recorded flag).
[0113]
If it is determined in step S25 that the difference is longer than the predetermined time, or after the processing in step S27 is completed, the recording / playback program 171 selects all the programs reserved in the reservation database 62 in step S28. If there is a program that has not yet been selected, the process returns to step S22, and the subsequent processing is repeated. If it is determined in step S28 that all programs have been selected, the process ends.
[0114]
Next, with reference to FIG. 15, a process for updating the recording reservation of a program by the reserved recording setting program 174 will be described.
[0115]
The process of updating the recording reservation of the program is also periodically performed at predetermined time intervals (for example, every 30 minutes). The setting time is also stored in the Flash ROM 52, and the setting can be changed at any time as necessary.
[0116]
In step S41, the scheduled recording setting program 174 determines whether or not there is a program reserved for recording in the reservation database 62 (FIG. 6), and when it is determined that there is no program reserved for recording. Then, the process of updating the recording reservation is finished.
[0117]
If it is determined in step S41 that there is a program reserved for recording, the process proceeds to step S42, and the reserved recording setting program 174 acquires current position information. The current position information is acquired from the extension module 11 attached to the portable television receiver 1 via the module interface (I / F) 54.
[0118]
In step S43, the scheduled recording setting program 174 selects one program that is scheduled to be recorded in the reserved database 62.
[0119]
In step S44, the scheduled recording setting program 174 reads the position where the recording of the program is reserved.
[0120]
Specifically, in step S13 in FIG. 12, the position information (current location in FIG. 6) acquired from the extension module 11 and stored in the reservation database 62 is read as a reserved position.
[0121]
In step S45, the scheduled recording setting program 174 determines whether or not the current position is within the same broadcast tower range as the reserved position.
[0122]
If it is determined in step S45 that the current position is within the same broadcast tower range as the position where recording is reserved, for example, the current position is within the broadcast range R1 of the broadcast tower T1 and the reserved position When a1 is also within the broadcast range R1 (when the user has not moved too far from the reserved position), the process proceeds to step S54, and the reserved recording setting program 174 determines whether all the programs have been selected. . If all the programs have not been selected, the process returns to step S43, the next one program is selected, and the same process is executed.
[0123]
If it is determined in step S45 that the current position is not within the same broadcast tower range as the reserved position, for example, if the user has moved to a position considerably away from the reserved position, the reservation is made in step S46. The recording setting program 174 accesses the program information server 111 from the communication unit 66 via the public line 101 and the Internet 102, transmits the current position and the program ID, and the currently selected program is broadcast at the current position. Request a search to see if there are plans. Based on this request, the program information server 111 executes a search from the registration list of FIG. 8 and transmits the search result to the portable television receiver 1.
[0124]
In step S47, the scheduled recording setting program 174 determines whether or not the program is scheduled to be broadcast at the current position based on the search result received from the program information server 111.
[0125]
If it is determined in step S47 that the program is scheduled to be broadcast at the current position, the process proceeds to step S48, and the broadcast start time and broadcast channel at the current position of the program are read from the search result of the program information server 111. .
[0126]
In step S49, the scheduled recording setting program 174 determines whether or not the broadcast start time or broadcast channel at the current position is different from the broadcast start time or broadcast channel at the time of reservation based on the information read out in step S48. judge.
[0127]
If it is determined in step S49 that the broadcast start time or broadcast channel at the current position is different from that at the time of reservation, the process proceeds to step S50, and the reservation recording setting program 174 updates the reservation information in the reservation database 62.
[0128]
For example, a case will be described in which when the portable television receiver 1 is in the position a1 of the area “A”, the program with the program ID “0001” is reserved for recording and then moved to the area “B”. As shown in FIG. 8, in the area “A”, the channel number on which the program with the program ID “0001” is broadcast and the broadcast start time are “6” and “08:50:00 on May 10, 2002” However, in the region “B”, the channel number on which the program with the program ID “0001” is broadcast and the broadcast start time are “7” and “13:50:00 on May 10, 2002”. Therefore, in this case, as shown in FIG. 6, the CPU 51 displays the program channel number, the broadcast start time, and the current location as the reservation information of the program ID “0001” stored in the reservation database 62 so far. As shown in FIG. 16, it is updated to “7”, “May 10, 2002, 13:50:00” and “b1”, respectively. Here, the current location “b1” represents a position included in the region “B”.
[0129]
If it is determined in step S49 that the broadcast start time or broadcast channel at the current position is not different from the reservation time (when update processing is not required), or if the update processing in step S50 is completed, in step S51. The reserved recording setting program 174 determines whether or not the selected program is a program that has requested alternative recording (a program that has been subjected to processing in steps S55 and S56 described later).
[0130]
If it is determined in step S51 that the selected program is a program that has requested alternative recording, in step S52, the scheduled recording setting program 174 performs the alternative recording for the other device requested in the process of step S55. Since it is no longer necessary (because the portable television receiver 1 has returned to a position where it can be recorded by itself), it is canceled.
[0131]
In step S53, the scheduled recording setting program 174 deletes the alternative recording information (flag) in the reserved list recorded in the reserved database 62. If it is determined in step S51 that the selected program is not a program for which alternative recording is requested, the processing in steps S52 and S53 is skipped because it is not necessary.
[0132]
Next, in step S54, the scheduled recording setting program 174 determines whether or not all programs have been selected. If it is determined in step S54 that all programs have not yet been selected, the process returns to step S43, and the subsequent processing is repeated.
[0133]
If it is determined in step S47 that the program is not scheduled to be broadcast at the current position, the process proceeds to step S55, and the scheduled recording setting program 174 determines that another device specified by the user (in the case of the example in FIG. 4). Request alternative recording to VTR 112). That is, in this case, since the user has moved to an area where the reserved program is not broadcasted, reserved recording is performed by another device in the area where the broadcast is performed.
[0134]
In step S56, the timer recording setting program 174 records alternative recording information (flag) in the timer list of the timer database 62. As described above, this alternative recording information is used to determine whether or not the program has requested alternative recording in the process of step S51.
[0135]
The above process is repeated, and if it is determined in step S54 that all programs have been selected, the process ends.
[0136]
Next, with reference to FIG. 17, a process for playing back a recorded program will be described. This process is started when reproduction is instructed by the user.
[0137]
In step S71, the recording / playback program 171 displays a playback menu on the display unit 2.
[0138]
In step S72, the recording / playback program 171 specifies a program to be played back based on an input from the user.
[0139]
In step S <b> 73, the recording / playback program 171 causes the designated program to be read from the HDD 158, decoded by the MPEG decoder 157, and output from the display unit 2.
[0140]
FIG. 18 shows an example of a playback menu screen displayed on the display unit 2 by the recording / playback program 171 in step S71.
[0141]
In this example, every time the channel selection button 217 is clicked, the recording / reproducing program 171 sequentially changes and displays programs to be reproduced one by one.
[0142]
In this example, a program whose recording channel is “6”, recording time is “9 minutes”, and whose program title is “Morning News” is displayed as a program to be reproduced.
[0143]
When the enter button 212 is clicked, the program to be played is determined.
[0144]
The recording / playback program 171 starts playback when the playback button 214 is clicked, pauses playback when the pause button 215 is clicked, and stops playback when the stop button 213 is clicked.
[0145]
In the above, an example in which the present invention is applied to the portable television receiver 1 has been described. However, the present invention is not limited to this, and for example, a mobile phone, a PHS (Personal Handyphone System), a PDA (Personal Digital Assistant) or The present invention can be widely applied to all devices having a position detection function, such as a terminal device such as a notebook personal computer.
[0146]
Further, although the position detection function is realized by the GPS function, it goes without saying that the position detection function of the PHS or the mobile phone can be used.
[0147]
The series of processes described above can be executed by hardware, but can also be executed by software. When a series of processing is executed by software, a program constituting the software may execute various functions by installing a computer incorporated in dedicated hardware or various programs. For example, it is installed from a recording medium in a general-purpose personal computer or the like.
[0148]
