The scheduled recording is executed based on the AV content to be recorded and the time supplied from the clock 132. Further, the reservation monitoring program 175 changes the setting of the AV content for executing the reservation recording.
[0088]
The receiving program 176 supplies the program ID obtained from the program information server 111 to the recording / reproducing program 171 from the communication unit 66 via the public line 101 and the Internet 102.
[0089]
For example, the receiving program 176 may be executed by an I / O (Input / Output) controller including an embedded computer that is also operating in the sleep mode, not shown.
[0090]
Next, with reference to FIG. 12, a description will be given of a process of programming recording of a program by the programmed recording setting program 174.
[0091]
In step S11, based on the input from the user, the reserved recording setting program 174 acquires the broadcast start time and the recording time of the program. The recording time indicates a time for actually recording a program desired by the user, but may be a broadcast time (a time when the program is broadcast).
[0092]
In step S12, the scheduled recording setting program 174 acquires a broadcast channel of the program based on the input from the user.
[0093]
In step S13, the scheduled recording setting program 174 acquires the current position information. The current position information is obtained from the extension module 11 mounted on the portable television receiver 1 via the module interface (I / F) 54.
[0094]
In step S14, the reservation recording setting program 174 causes the reservation database 62 to store the broadcast start time, recording time, broadcast channel, and current position information of the program.
[0095]
In step S15, the scheduled 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 acquires the broadcast channel and the broadcast start acquired in the processing in steps S11, S12, and S13. The time and the current position information (and the broadcast time as 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 to search for the channel number of the broadcast channel in the area including the current location and the program ID of the program being broadcast at the broadcast start time. I do.
[0096]
For example, when data of the current location “a1”, the channel number “6”, and the broadcast start time “08:55:00 on May 10, 2002” are transmitted, the current location “a1” is included in the area “A”. Therefore, among the programs broadcast in the area “A”, the program ID of the program whose broadcast start time is “08:55:00 on May 10, 2002” on channel “6” is “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 reservation recording setting program 174 stores the program ID in the reservation database 62 (FIG. 6).
[0098]
As described above, the channel number, recording time, broadcast start time, program ID, and current location (reserved location) of the program reserved by the user are registered in the reservation database 62 as shown in FIG.
[0099]
As described above, the user operates the display unit 2 to input the channel number, the broadcast start time, and the recording time at the time of reservation. The input operation at this time will be further described with reference to FIG.
[0100]
When a reservation is instructed by the user, the reservation recording setting program 174 causes the display unit 2 to display a reservation screen as shown in FIG. On this reservation screen, a channel to be reserved for recording, a broadcast start time, a program content, 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 “08:55:00 on May 10, 2002”. 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 and active by the user, the channel selection button 217 and the determination button 212 become 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 decision button 212 is clicked, the inputted reservation information is confirmed.
[0103]
On the other hand, when the recording reservation window 211 is selected and active, the stop button 213, the play button 214, and the pause button 215 become inactive, and the recording / playback program 171 clicks the play button 214 or the pause button 215. Does not work.
[0104]
The program selection button 217, which will be described later with reference to FIG. 18, is a button for selecting a program to be played when playing a recorded program.
[0105]
Next, a process of recording a program by the recording / playback 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 / reproducing 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. I 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 of the reservation database 62.
[0108]
In step S23, the recording / playback program 171 reads the broadcast start time of the selected program recorded in the reservation database 62.
[0109]
In step S24, the recording / playback program 171 acquires the current time from the clock 132 of the extension module 11.
[0110]
In step S25, the recording / playback program 171 determines whether the difference between the current time acquired in step S24 and the broadcast start time read in the processing in step S23 is equal to or less than a predetermined time, and 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 record the program on the HDD 158 of the recording / reproducing unit 63. At this time, when the program is not encoded, the program is recorded after being encoded by the MPEG encoder 156, and when the program is encoded, the program is recorded as it is.
[0111]
The predetermined time is set in advance and stored in the flash ROM 52 in advance. For example, consider a 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 “08:55:00 on May 10, 2002”, and the current time is “May 10, 2002”. After 08:49:30, the difference is determined to be less than or equal to the predetermined time in step S25, and the program is recorded in the recording / reproducing unit 63 in step S26. Of course, this time can be set to, for example, 10 seconds, 15 seconds, or 20 seconds.
[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]
In step S25, when it is determined that the difference is longer than the predetermined time, or after the processing in step S27 is completed, in step S28, the recording / playback program 171 selects all the programs reserved in the reservation database 62. It is determined whether or not the program has not been selected. If there is a program not yet 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 description will be given of a process of updating the recording reservation of a program by the reservation recording setting program 174.
[0115]
The process of updating the recording reservation of this program is also periodically performed at predetermined time intervals (for example, every 30 minutes). The set time is also stored in the Flash ROM 52, and the setting can be changed to an arbitrary time as needed.
[0116]
In step S41, the reservation 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 ends.
[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 obtained from the extension module 11 mounted on the portable television receiver 1 via the module interface (I / F) 54.
[0118]
In step S43, the reservation recording setting program 174 selects one program reserved for recording in the reservation database 62.
[0119]
In step S44, the reserved recording setting program 174 reads out the position where the recording of the program is reserved.
[0120]
Specifically, in step S13 in FIG. 12, the position information (current position in FIG. 6) acquired from the extension module 11 and stored in the reservation database 62 is read as the reservation position.
[0121]
In step S45, the scheduled recording setting program 174 determines whether the current position is within the same broadcast tower as the reserved position.
[0122]
In step S45, when it is determined that the current position is within the same range of the broadcast tower as the position where the 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 to a position far from the reserved position), the process proceeds to step S54, and the reserved recording setting program 174 determines whether or not all programs have been selected. . If all the programs have not been selected yet, the process returns to step S43, the next one program is selected, and the same processing is executed.
[0123]
If it is determined in step S45 that the current position is not within the same range of the broadcast tower as the reserved position, for example, if the user has moved to a position far away from the reserved position, 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 broadcasts the currently selected program at the current position. Request a search for a schedule. Based on this request, the program information server 111 executes a search from the registration list in 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, where the broadcast start time and the 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 the broadcast start time or the broadcast channel at the current position is different from the broadcast start time or the broadcast channel at the time of the reservation based on the information read in the processing in step S48. judge.
[0127]
If it is determined in step S49 that the broadcast start time or the broadcast channel at the current position is different from that at the time of the 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 at the position a1 of the area "A", a program with the program ID "0001" is reserved for recording, and thereafter, the program moves to the area "B". As shown in FIG. 8, in the area “A”, the channel number and the broadcast start time at which the program with the program ID “0001” is broadcast are “6” and “May 10, 2002 08:55:00 seconds”. However, in the area “B”, the channel number and the broadcast start time at which the program with the program ID “0001” is broadcast are “7” and “13:55:00 on May 10, 2002”. Therefore, in this case, as shown in FIG. 6, the CPU 51 stores 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, the information is updated to “7”, “13:55:00 on May 10, 2002”, and “b1”, respectively. Here, the current location “b1” indicates a position included in the area “B”.
[0129]
In step S49, when it is determined that the broadcast start time or the broadcast channel at the current position is not different from the time of the reservation (when the update process is not required), or when the update process in step S50 is completed, the process proceeds to 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 the processing of steps S55 and S56 described later).
[0130]
If it is determined in step S51 that the selected program is the program that has requested the alternative recording, in step S52, the scheduled recording setting program 174 sets the alternative recording for the other device requested in the processing in step S55 to the Since it is no longer necessary (since the portable television receiver 1 has returned to a position where it can record by itself), it is canceled.
[0131]
In step S53, the reservation recording setting program 174 deletes the substitute recording information (flag) of the reservation list recorded in the reservation database 62. If it is determined in step S51 that the selected program is not the program that has requested the alternative recording, the processes in steps S52 and S53 are skipped because there is no need.
[0132]
Next, in step S54, the reserved 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 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, where the scheduled recording setting program 174 determines whether another device designated by the user (in the example of FIG. VTR 112). That is, in this case, since the user has moved to an area where the reserved program is not broadcast, the scheduled recording is performed by another device in the area where the broadcast is performed.
[0134]
In step S56, the reservation recording setting program 174 causes the reservation list of the reservation database 62 to record the substitute recording information (flag). As described above, this alternative recording information is used in the processing of step S51 to determine whether or not the program has requested the alternative recording.
[0135]
The above processing is repeated, and if it is determined in step S54 that all programs have been selected, the processing ends.
[0136]
Next, a process of reproducing a recorded program will be described with reference to FIG. This process is started when a user instructs reproduction.
[0137]
In step S71, the recording / playback program 171 causes the display unit 2 to display a playback menu.
[0138]
In step S72, the recording / reproducing program 171 specifies a program to be reproduced based on an input from the user.
[0139]
In step S73, 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 illustrates an example of a playback menu screen displayed on the display unit 2 by the recording and playback program 171 in step S71.
[0141]
In this example, each time the channel selection button 217 is clicked, the recording / reproducing program 171 sequentially changes and displays the programs to be reproduced one by one.
[0142]
In this example, a program whose recording channel is “6”, whose recording time is “9 minutes”, and whose program title is “Morning News” is displayed as a program to be reproduced.
[0143]
Then, when the decision button 212 is clicked, the program to be reproduced is decided.
[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. For example, a portable telephone, a PHS (Personal Handyphone System), a PDA (Personal Digital Assistant), or The present invention can be widely applied to all devices having a position detecting function, such as a terminal device such as a notebook personal computer.
[0146]
Further, the position detection function is realized by the GPS function. However, 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 built into dedicated hardware or installing various programs. It is installed from a recording medium into a possible general-purpose personal computer or the like.
[0148]
As shown in FIG. 4, a recording medium that is installed in the computer and records a program that can be executed by the computer includes a magnetic disk 91 (including a flexible disk) and an optical disk 92 (CD-ROM (Compact Disc-Read)). Only Memory, a DVD (including a Digital Versatile Disc), a magneto-optical disk 93 (including an MD (Mini-Disc) (registered trademark)), or a package medium including a memory card mounted in place of the extension module 11 Or a flash ROM 52 in which a program is temporarily or permanently recorded, a hard disk, or the like. The recording of the program on the recording medium is performed using a wired or wireless communication medium such as a public line network, a local area network, the Internet, or digital satellite broadcasting via an interface such as a modem as necessary.
[0149]
In this specification, the steps of describing a program recorded on a recording medium may be performed in chronological order according to the described order, but may not be performed in chronological order. This also includes processes executed individually.
[0150]
Also, in this specification, a system refers to an entire device including a plurality of devices.
[0151]
