BEST MODE FOR CARRYING OUT THE INVENTION

Exemplary embodiments of a recording / reproducing apparatus, a recording / reproducing method, a recording / reproducing program, and a computer-readable recording medium according to the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram showing a functional configuration of a recording / reproducing apparatus according to an embodiment of the present invention. The recording / reproducing apparatus according to this embodiment includes an image receiving unit 101, a determining unit 102, a recording unit 103, a reproducing unit 104, a display unit 105, and an instruction unit 106.

[0014] The image receiving unit 101 receives video of a program. For example, a tuner receives a radio wave of a TV image and displays the TV image on a TV screen. The program can be a TV program, an AM'FM radio broadcast, or other video's audio broadcast. Programs can be specified by channel and time zone, but can also be specified by program name and code number. The video of the designated program can be received. Determination unit 102 determines whether the vehicle is stopped or traveling. Whether the vehicle is stopped or running can be determined by checking whether the accessory power is on. In this case, it can be determined that the accessory power source is on and the accessory power source is off while the vehicle is stopped. It can also be determined by whether the parking brake is applied. Further, it can be determined by detecting the vibration state of the vehicle with a sensor. It is also possible to determine that the vehicle is running when the key is inserted into the vehicle and that the vehicle is stopped when it is removed. In addition, when the key is applied to the vehicle door with the key removed, the vehicle is judged to be stopped.When the key is inserted into the vehicle and the key is applied to the vehicle door, Can be determined.

The recording unit 103 records the video of the program received by the image receiving unit 101 from the time when the determination unit 102 determines that the vehicle is stopped until the end of the program. Recording of the program can be started automatically upon determination, but recording can also be started by prompting the passenger to determine whether or not to record the program and accepting the passenger's input.

[0017] When the program is recorded by the recording unit 103 and the determination unit 102 determines that the vehicle is running, the playback unit 104 displays the video of the program recorded by the recording unit 103. The time force determined by the determination unit 102 that the vehicle has stopped is also reproduced. Playback can be started automatically upon receipt of the determination, but playback can also be started by prompting the passenger to decide whether to play the program and accepting the passenger's input.

[0018] It should be noted that the playback unit 104 interrupts the playback of the program video when the determination unit 102 determines that the vehicle is stopped while the program video is being played back, and the program video If the determination unit 102 determines that the vehicle is running after interrupting the playback, the playback of the program video can be resumed.

The playback unit 104 plays back the video of the program in a time shorter than the time recorded by the recording unit 103, and the recording unit 103 records the scene played back by the playback unit 104 and the recording unit 103. If the scenes to be matched match, the recording can be ended.

[0020] When the recording unit 103 records the program video and the determination unit 102 determines that the vehicle is running, the display unit 105 records the program video by the recording unit 103. To display that. [0021] The instruction unit 106 instructs the reproduction of the video of the program. When the recording unit 103 records the program video and the instruction unit 106 instructs the playback of the program video, the playback unit 104 displays the program video recorded by the recording unit 103. The playback starts from the time when the determination unit 102 determines that the vehicle has stopped.

FIG. 2 is a flowchart showing processing of the recording / reproducing method according to the embodiment of the present invention. First, the image receiving unit 101 receives a video of a program (step S201). Next, the determination unit 102 determines whether the vehicle is stopped or traveling (step S202). If the determination unit 102 determines that the vehicle is stopped (step S202: Yes), the recording unit 103 records the video of the program received by the reception unit 101 until the end of the program (step S202: Yes). S20 3).

[0023] Note that the display unit 105 displays the program video by the recording unit 103 when the recording unit 103 determines that the vehicle is traveling when the program unit 103 records the program video. It is recorded and displayed.

If the determination unit 102 determines that the vehicle is traveling (step S202: No), it is determined whether or not the recording unit 103 is recording a program (step S204). If recording is not in progress (step S204: No), the series of processing ends. When recording is in progress (step S204: Yes), the playback unit 104 plays back the video of the program recorded by the recording unit 103 when the vehicle stops.

[0025] When it is determined that the vehicle is stopped after the program is started to be played, the playback of the video of the program can be interrupted. On the other hand, if it is determined that the vehicle is running after the program video playback is interrupted, the program video playback can be resumed. Also, during playback, the program video is played back in a shorter time than the recorded time. When the scene played back by the playback unit 104 matches the scene recorded by the recording unit 103, the recording ends. You can also. Further, in the reproduction, when the instruction unit 106 instructs the reproduction of the program video, the program video can be reproduced.

[0026] According to the embodiment described above, it is possible to watch the program halfway while the vehicle is stopped and to record the program until the end. And when you drive the vehicle again, you can watch the power when you started recording, so even if you leave the vehicle in the middle of the program, When driving a vehicle, you can continue watching the program.

The network 315 includes a television broadcasting station network, a LAN, a WAN, a public line network, a mobile phone network, and the like.

FIG. 4 is an explanatory diagram for explaining the traveling state of the own vehicle and the recording / reproducing state of the program. First, at T401, the vehicle is running and watching a program. Next, at T402, the vehicle stops and the passenger gets off. This timing may be the time when the vehicle stops, or may be the time force at which it is determined that the door is opened and the passenger gets off. Program recording starts when the vehicle is stopped. The point where this recording starts is followed and recorded as a playback point. The chasing playback point is a point indicating when the viewing ends.

[0034] Next, at T403, the passenger returns and the vehicle starts to travel. This timing can be set as the start of travel if the vehicle is alighted at the time of stopping, and the start of travel is determined by the boarding state due to opening / closing of the door when it is determined that the vehicle is getting off by opening / closing the door. be able to. Here, the recorded program is reproduced by follow-up reproduction. Chasing playback refers to playing a recorded program without waiting for the recording to end while recording the program. Here, playback is started from the follow-up playback point at T402.

[0035] As for the video of the program, only the digest part and the highlight part may be reproduced. In addition, parts that are judged to be necessary for the viewer, such as scenes that are not commercial or interested, may be skipped by fast-forwarding. In this way, when playing only a part of a program, Playback time is shortened. As a result, it may catch up with the current recording position. In this case, recording of the program can be terminated, and normal real-time program viewing can be resumed.

[0036] Next, the program ends at T404. The recording ends here. On the other hand, since the recorded program has not been played back, the program continues to play. At T405, program playback ends. Here, all the chasing playback processes are completed.

[0037] In this way, when watching a program, when you get out of your vehicle for some reason, record the video of the program, and later record the program you recorded when you traveled back to your vehicle. Play the video. Or, record the part before getting into the vehicle and play it back and forth. Or you can record the program you were watching while the vehicle was stopped when the vehicle started running and play it when it stops again, so that you can watch it smoothly even in a traffic jam.

[0038] The program to be recorded may be specified by being input in the host vehicle, but may be input via the network 315 from home or a destination. This program can be specified by specifying the program name as a user interface, entering it with a code number, or entering it with a channel number and time zone.

[0039] The recording start timing can be the time when the vehicle starts running while viewing a program while the vehicle is stopped. It can also be the case when the engine is turned off while watching a TV program. At this time, the recording may be started automatically, but the passenger may determine whether or not to record by sound or screen display. It is also possible to record the continuation of the program on an external computer such as a home or an HDD recorder. In this case, the program information is transmitted via the network 315, and the continuation of the program is recorded based on the program information received at the destination.

FIG. 5 is a flowchart for explaining processing for recording a program according to this embodiment. First, it is determined whether or not a TV source has been selected! (Step S501). If no TV source is selected (step S501: No), wait until it is selected. The TV source is, for example, a TV channel. By selecting this TV source, a program to be received and recorded can be specified.

[0041] When the TV source is selected (step S501: Yes), it is checked whether the vehicle has stopped. Determination is made (step S502). If the vehicle is not stopped (Step S502: No), wait until it stops. When the vehicle stops (step S502: Yes), recording of the program being watched is started and a chase playback point is given (step S503). By giving this chasing playback point, it is possible to specify the position where playback starts when the passenger gets off and returns again.

Next, it is determined whether or not the program has ended (step S504). When the program ends (step S504: Yes), the recording ends (step S505), and the series of processing ends. If the program has not ended (step S504: No), recording is continued and the process returns to step S504. In this way, it is possible to record until the end of the time program when the passenger gets off, and to watch it when boarding again.

FIG. 6 is a flowchart for explaining the reproduction process of this embodiment. First, it is determined whether or not the vehicle is stopped (step S601). If the vehicle is not stopped (step S601: No), the series of processes is terminated. When the vehicle is stopped (step S601: Yes), chasing playback is started (step S602).

[0044] Next, it is determined whether or not the power has been completely reproduced (step S603). When all the playbacks have been completed (step S603: Yes), the series of processing ends. If all the regenerations are completed and V, (step S603: No), it is determined whether or not the vehicle has started to travel (step S604). If the vehicle has started to drive! / ヽ (step S604: No), it waits until it starts to drive. When the vehicle starts running and hits (Step S604: Yes), a playback point is added to stop and playback is stopped (Step S605). And it returns to step S601

[0045] FIG. 7 is a flowchart for explaining processing when chasing playback is started. First, during recording, it is determined whether or not there is a recorded program (step S701). If there is no recorded program during recording (step S701: No), the series of processing ends. If there is a recorded program during recording (step S701: Yes), it is determined whether or not there is a follow-up playback point (step S702). If there is no chasing playback point (step S702: No), the series of processes is terminated. If there is a chasing playback point (step S702: Yes), the user is confirmed to start chasing playback (step S703). Next, based on the confirmation result, it is determined whether or not the power to start the follow-up reproduction is determined (step S704). If the follow-up playback is not performed (step S704: No), the series of processing ends. If the follow-up playback is to be performed (step S704: Yes), the follow-up playback is started (step S705), and the series of processes is terminated.

[0047] The timing for starting the follow-up playback may be when the vehicle is boarded or when the vehicle starts running. Chasing playback can be automatic playback at this timing, but the passenger may determine whether or not to perform chasing playback based on voice or screen display. In addition, chasing playback may be performed at the same time as boarding or running, but force regeneration can also be started after a predetermined time has elapsed from the start of running. By allowing a certain amount of time to elapse, it is possible to more reliably confirm that the vehicle has started running and to start the power regeneration.

[0048] Also, if you start recording a program and turn off the power engine to temporarily leave your vehicle, the power that was playing when the engine was turned off when the engine was turned on is also played. Can also be resumed. Also, contrary to the above description, recording can be started when the vehicle starts traveling, and chasing playback can be started when the vehicle stops.

[0049] In addition, for programs such as sports programs that are favored for real-time viewing, it is possible to follow and reproduce only the digest portion. Digest playback refers to playback that focuses on the digest part of the announcement, such as before and after the cheering. Digest playback allows you to catch up with the current progress while following the outline and development of the parts that could not be watched. Therefore, even if it is difficult to watch a program while getting off, it is possible to watch the program in real time while understanding the program on a large scale.

[0050] According to the embodiment described above, a program can be viewed while the host vehicle is running, and the continuation of the program after getting off can be recorded even when getting off the vehicle. And when you board again, you can watch the program again when you get off, so even if you have to stop watching the program, you can watch and watch the program without interruption be able to.

[0051] After getting off, when he boarded again, he did not realize that the program was recorded from the middle, Since the program may be watched, the passenger may accidentally switch to another program by notifying the passenger that the program has been recorded even after getting off when the passenger returns to the vehicle. The program that has been viewed halfway can be viewed without interruption.

[0052] Further, when viewing a recorded program, the user may get off again. In that case, playback of the recorded program is interrupted, and the program can be viewed without being interrupted by playing back the point where the program was interrupted when boarding again.

[0053] In addition, there is a case where a program is played back in a shorter time than the recorded time by fast-forward playback or playing back only the digest part rather than watching the recorded program as it is. At this time, the program playback position may catch up with the program recording position. In this case, the program recording is completed and the program is received, thereby eliminating the trouble of recording the program and viewing the recorded program. In addition, the received program can be viewed in real time from the time when the program has caught up.

Note that the recording / reproducing method described in the present embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. This program is recorded on a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, and a DVD, and is executed by being read by the computer. The program may be a transmission medium that can be distributed via a network such as the Internet.
