BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described.
[0010]
FIG. 1 is a block diagram showing an embodiment of the present invention.
[0011]
In FIG. 1, reference numeral 1 denotes a receiving unit. The receiving unit 1 receives a digital or analog television broadcast.
[0012]
2 is a writing unit. The writing unit 2 stores (writes) the video / audio signal received by the receiving unit 1 in a storage unit 3 described later. The video and audio to be written may be in any file format such as MPEG or AVI, and may be of a type such as a time code or a frame code which indicates the current reproduction position as described later. If so, the type is not particularly limited.
[0013]
Reference numeral 3 denotes a storage unit. The storage unit 3 is configured by, for example, a hard disk (HD). Then, the received video / audio signal is written by the writing unit 2.
[0014]
Reference numeral 4 denotes a traveling detection unit. The traveling detection unit 4 monitors the traveling of the automobile, and outputs a traveling start detection signal when the automobile starts traveling and a traveling stop detection signal when the traveling is stopped.
[0015]
Reference numeral 5 denotes a reproducing unit. The playback unit 5 has a time shift function, reads out video and audio signals from the storage unit 3 in response to the travel stop detection signal from the travel detection unit 4, and plays back video and audio. In addition, the reading of the video / audio signal is stopped in response to the traveling detection signal, and the reproduction of the video / audio is stopped.
[0016]
Here, the start and stop of the reproduction will be described in more detail with reference to FIG.
[0017]
The reproduction unit 5 does not reproduce the image when the vehicle is running, but does it when the vehicle is stopped.
[0018]
As shown in FIG. 2, the reproducing unit 5 starts reading the video / audio signal in response to the traveling stop detection signal. At this time, the first position of the recorded video is reproduced.
[0019]
After that, the reproducing unit 5 stops reading the video / audio signal in response to the traveling detection signal, and stores the part where the reproduction of the video / audio is stopped when the reading is stopped. For example, in FIG. This position is stored as a time code, a frame number, or the like.
[0020]
Subsequently, the reproducing unit 5 starts reading the video / audio signal in response to the traveling stop detection signal. The video and audio to be reproduced at this time are started from the position where the previous reproduction was stopped. In FIG. 2, the reproduction of the video starts from the position A, that is, the subsequent video whose reproduction was previously stopped is reproduced.
[0021]
In this way, the reproduction of the video / audio is stopped when the vehicle is running, and the reproduction is continued from the continuation of the video / audio previously stopped when the driving is stopped.
[0022]
In the running stop state, the time code or the like at the moment when the running state is detected may be stored, and the playback may be started several seconds before, for example, three seconds before the playback.
[0023]
Reference numeral 6 denotes a display unit on which the video read by the reproducing unit 5 is displayed.
[0024]
Reference numeral 7 denotes an audio output unit which outputs the audio read by the reproducing unit 5.
[0025]
Next, the operation in the above configuration will be described.
[0026]
First, start or stop of traveling is detected (Step 100). As a result of the detection, if it is a traveling start signal (Step 101), the reproduction of the video / audio is stopped (Step 102). Then, the position where the reproduction is stopped in the recorded video is stored (Step 103).
[0027]
On the other hand, if the detection result indicates that the signal is a running stop signal (Step 101), the stored position at which the previous reproduction was stopped is confirmed (Step 104). Then, the video / audio is reproduced from the stop position (Step 105).
[0028]
As described above, according to the present invention, the video is reproduced only when the driving of the automobile is stopped, and the reproduction of the video and audio is automatically started from the position where the reproduction was stopped last time. You can safely watch video and audio without spending too much time.
[0029]
In the above-described embodiment, the receiving unit for receiving the television broadcast or the like is provided, and the received video / audio is recorded and reproduced. However, for example, the recording unit is already provided without the receiving unit or the like. It may be configured to reproduce the recorded video / audio.
[0030]
【The invention's effect】
The present invention detects the traveling of a car, suspension of traveling, stops the reproduction of video and audio at the start of traveling, stores the position where the reproduction was suspended, and stores the position of reproduction of video and audio at the time of traveling suspension from the position where the previous reproduction was suspended. Since it is configured to reproduce, there is an excellent effect that it is safe and time for heading can be eliminated.
