BACKGROUND OF THE INVENTION
The present invention relates to an in-vehicle TV recording / reproducing apparatus that is mounted on a vehicle, receives a television (hereinafter sometimes abbreviated as “TV”) broadcast, and can perform recording and reproduction.
[0002]
[Prior art]
Conventionally, some devices having an audio-visual (AV) function mounted on a vehicle can also receive television broadcasts, and passengers other than the driver such as passengers of the vehicle can watch the television broadcasts. can do. However, it is dangerous for the driver to watch the video of the television broadcast while the vehicle is traveling, and the driver can view the television broadcast only when the vehicle is stopped. When a driver of a vehicle wants to watch a television broadcast program broadcast while driving, it needs to record once and play it later. Recording of a program can be performed using a reservation function or the like with a recording / playback apparatus outside the vehicle.
[0003]
As a recording / reproducing apparatus, a device that uses a tape-like or disk-like recording medium is generally used. However, such a recording / playback apparatus cannot play back a video different from the video being recorded. A recording / playback apparatus capable of playing a video different from the video being recorded is disclosed in, for example, Japanese Patent Application Laid-Open No. 2000-350130. In this prior art, a recording medium such as a hard disk device (HDD) is built in as an external storage means that can be randomly accessed, video data can be compressed and recorded, and the recorded video data can be expanded and reproduced. . Since the video data actually recorded on the recording medium is compressed, video data can be recorded and played back for a long time with respect to the actual access time to the recording medium. It is possible to play back video data that has already been recorded. The video data recorded on the recording medium can be freely reproduced, and in particular, time-shifted reproduction in which the video data being recorded is reproduced while being shifted in time is also possible.
[0004]
In addition, Sony Corporation has released a hard disk video recorder under the model name SVR-715. With this product, it is possible to play a variety of formats, such as “chasing playback” where the program being recorded can be viewed from the beginning, and “quick playback” that reduces the playback time while listening to the audio. .
[0005]
[Problems to be solved by the invention]
When there is a television broadcast program that the vehicle driver wants to watch, a conflicting demand arises that “If you watch the TV while driving, you do not want to miss the dangerous TV”. Even if a television broadcast program is recorded with the reservation function of the recording / playback device outside the vehicle and then played back later, it is played back only after the vehicle has moved to the place where the recording / playback device is installed. Since it cannot be performed, it takes time from broadcasting to reproduction, and the waiting time of the driver increases.
[0006]
If a hard disk device or the like is used as a recording medium and a recording / playback device capable of time-shift playback is installed in the vehicle, the driver can run while recording a television broadcast and perform time-shift playback when the vehicle is stopped. There is a possibility that the time required from broadcasting to reproduction can be shortened. However, the recorded content can only be understood by playing it. Even if you try to play from the first recorded part when the existence of the part you want to see is unknown, if the stop time is short, it may end only by playing only the less important part . Also, when the vehicle is traveling, the reception state of the television broadcast also changes with time, and even if the part to be seen is known, the reception state may be poor during the broadcast. Even if it is determined that the reception state is poor, the time for reproduction is wasted.
[0007]
An object of the present invention is to provide an in-vehicle TV recording / playback apparatus capable of ensuring safety during driving of a vehicle and effective viewing of a television broadcast.

You can also The recording medium 3 is, for example, a hard disk, a digital versatile disc capable of recording / reproducing such as a DVD-RAM or DVD-RW, a semiconductor memory, etc., which has a large recordable capacity and can be recorded / reproduced at high speed at random. Realized using. If the television broadcast is a digital system, demodulated data is recorded, and if it is an analog system, the demodulated signal is converted into digital data and recorded. In recording, the time axis is compressed and recorded.
[0024]
FIG. 2 shows a general procedure for receiving, recording, and reproducing a television broadcast in the in-vehicle TV recording / reproducing apparatus 1 of the embodiment of FIG. This procedure is for the front seat where the driver sits. When the power switch is turned on, the procedure is started from step a0. At step a1, a television broadcast is received. For example, when data composing one frame of video and data representing audio in the meantime are received, data representing the received video and audio is recorded on the recording medium 3 in step a2. In step a3, audio playback is also performed. At this time, the video is not played back. In step a4, based on the vehicle speed data from the vehicle speed detection sensor 15, it is determined whether or not the vehicle is traveling. If the vehicle speed data is not 0 and the vehicle is traveling, the process returns to step a1. When the vehicle is running, only sound is reproduced.
[0025]
If it is determined in step a4 that the vehicle speed data is 0 and the vehicle is not running, it is determined in step a5 whether or not there is an instruction input from the front seat input device 9. If there is no instruction input, in step a6, the recording capacity of the video that has been recorded on the recording medium 3 and has not been reproduced is calculated. In step a7, the playback speed is determined according to the recording capacity. For example, when the recording capacity is longer than a certain time, the fastest playback speed is set, and when the recording capacity is reduced, the playback speed is also slowed down. However, it should be faster than the playback speed in real time. In step a8, video time-shifted playback is performed at the set playback speed. In step a9, the audio data corresponding to the video to be reproduced is reproduced in a short time to skip the silent part.
[0026]
That is, the in-vehicle TV recording / reproducing apparatus 1 of this embodiment is mounted on a vehicle and can record and reproduce a video by receiving a television broadcast. The recording medium 3, the vehicle speed detection sensor 15, and the in-vehicle TV apparatus 2 Including. The recording medium 3 functions as a recording / playback unit that receives a received television broadcast and can record and play back the video, so that the video of the television broadcast can be recorded and played back. Since the vehicle speed detection sensor 15 functions as a travel monitoring unit that monitors the travel state of the vehicle, it can detect whether the vehicle is traveling as a monitoring result. The in-vehicle TV device 2 prohibits the display of the video of the television broadcast while the vehicle is running, according to the vehicle speed data that is the monitoring result of the vehicle speed detection sensor 15, and records the video (only the audio is reproduced in real time). However, while the vehicle is stopped, the recording medium 3 is controlled so as to reproduce the portion of the video that has already been recorded with a time shift that shifts the time while continuing to record the video. While the vehicle is running, the video of the television broadcast is recorded and only the audio is played back in real time, so the contents of the broadcast and the reception status can be known by audio. In addition, the audio may be switched to another source (for example, MD, CD, etc.) and reproduced while recording a television broadcast video. Therefore, since the video is not reproduced, the driver of the vehicle does not watch the video, and the visual acuity can be used for driving the vehicle to ensure safety during driving. When the vehicle stops, the recorded video is reproduced with a time shift, so that the driver of the vehicle can gaze at the portion that he / she wants to see determined from the result of listening to the audio reproduction in real time.
[0027]
In the present embodiment, the in-vehicle TV apparatus 2 controls the recording medium 3 so that the recorded video is played back at a speed faster than the playback speed in real time when the recorded video is played back with time shift. When playing back the recorded video with time shift, it will play at a speed faster than the playback speed in real time, so if you continue playing in time shift, the time difference from the video broadcast in real time will be reduced Can catch up. The speed at which the video is played back by time shift is controlled to be faster when the capacity is large, corresponding to the capacity of the video to be played back by time shift playback. For example, when the elapsed time from the previous stop is long and the video recorded from the time-shifted playback portion is large, the time-shift playback speed is controlled to be faster at the next stop, so recording in a short time You can see the images being played. Also, in response to increasing the playback speed during playback with time shift of the video, the audio corresponding to the video is controlled to be played back in a shorter time with the silent part shortened, so the playback speed of the video is increased. However, the sound can be played back without changing the pitch and quality, and can be played back without losing the characteristics of the speaker.
[0028]
When it is determined in step a5 in FIG. 2 that there is an instruction input to the front seat input device 9, reproduction is performed in accordance with the instruction in step a10. After step a10, the process returns to step a1. For example, when the driver knows the part he / she wants to see by listening to the voice, the part can be designated and reproduced by input to the front seat input device 9. Note that the reproduction for the rear seat using the rear seat display device 6 and the rear seat speaker 8 may be performed based only on the instruction input to the rear seat input device 10, and is usually performed in real time while the vehicle is running. John broadcast can be played.
[0029]
In the embodiment, the time-shift playback at the time of stopping the video recorded while the vehicle is traveling is performed only in a place related to a predetermined driving such as a driver's seat. Since video is always played back in real time at the same time as recording, passengers other than the driver can watch the video as a normal television broadcast.
[0030]
FIG. 3 shows the structure of data recorded on the recording medium 3 of FIG. The received video data of the television broadcast is recorded with the video data numbers sequentially assigned to the recording medium 3 as recording data, for example, every one or a predetermined number of frames. Audio data received simultaneously with the video data is also recorded as the recording data for the same video data number. In a portion where the reception state is bad, 1 is set as a flag, and deterioration times w1, w2 and the like corresponding to the length of the section in which flag 1 continues are recorded in the first data of the portion where flag 1 continues.
[0031]
In the in-vehicle TV recording / reproducing apparatus 1 of the present embodiment, the electric field detection circuit 14 in the in-vehicle TV apparatus 2 is caused to function as reception monitoring means for monitoring the reception state of the received television broadcast. The in-vehicle TV device 2 excludes a part of the video when the reception state of the television broadcast is worse than a predetermined reference from the target to be reproduced by time shift according to the reception state detected by the electric field detection circuit 14. The recording medium 3 is controlled. If the television broadcasting reception condition does not reach a predetermined standard, for example, a certain electric field strength, or the signal-to-noise ratio (S / N ratio) is worse than a certain value, the video is subject to time shift reproduction. Therefore, it is possible to perform effective time shift reproduction without reproducing a video with a bad reception state.
[0032]
FIG. 4 shows a control procedure at the time of recording in which the in-vehicle TV apparatus 2 records data as shown in FIG. 3 on the recording medium 3. The procedure starts from step b0. In step b1, video and audio for a predetermined time are recorded on the recording medium 3. In step b2, it is determined whether or not the electric field intensity detected by the electric field detection circuit 14 is lower than a predetermined reference and the reception state is deteriorated. When the television broadcast is performed in a digital manner, it is encoded so that an error can be detected. Therefore, it is possible to determine the deterioration of the reception state based on the error detection state. When it is determined that the reception state has not deteriorated, the process returns to step b1 to continue recording. At this time, the flag shown in FIG.
[0033]
If it is determined in step b2 that the reception state has deteriorated, the flag is set to 1 in step b3, and the timer 13 measures time in step b4. In step b5, it is determined whether or not the reception state has been recovered. If it is determined that the reception state has not been recovered, the process returns to step b4 and time measurement is continued. When it is determined in step b5 that the reception state has been recovered, the flag is set to 0 in step b6, the measurement time of the timer 13 is added to the first data of the reception state deterioration in step b7, and the timer is set in step b8. 13 is reset and it returns to step b1.
[0034]
FIG. 5 shows a control procedure during reproduction for reading data from the recording medium 3 on which data as shown in FIG. 3 is recorded. The procedure starts from step c0. In step c1, the recorded data and the recorded data are read in the order of the recorded video data numbers, and in step c2, it is determined whether or not the deterioration time is added. If it is determined that the deterioration time is added, in step c3, the video of the recording data corresponding to the video data number immediately before the video data number to which the deterioration time is added is statically displayed. In step c4, the recorded data is reproduced as audio data. In step c5, the recorded data and the recorded data corresponding to the next video data number are read out, and in step c6, it is determined whether or not reading for the deterioration time has been completed. When it is determined that the reading for the deteriorated time has not been completed, the process returns to step c4 and the reproduction of only the sound is continued. If it is determined in step c6 that the readout for the deterioration time has been completed, the video and audio are reproduced in step c7 for the read recorded data and recorded data, and the process returns to step c1.
[0035]
Note that the playback speed can be increased as described above by reducing the recording data for each video data number and the time interval for reading the recording data. Further, when the reception state is deteriorated, it is possible not to perform recording. Furthermore, when the sound is reproduced in real time, the reproduction can be skipped without performing the static display of the reception deteriorated state. In addition, when the vehicle is traveling, only recording and recording are performed in accordance with an instruction from the front seat input device 9, and processing for deterioration of the reception state is performed at that time. When playing back audio, it is also possible to perform playback by excluding the part where the reception state deteriorates.
[0036]
As described above, according to the present invention, only the sound is reproduced in real time while the video of the television broadcast is being recorded while the vehicle is running, so that it is possible to know the content and reception state of the broadcast by sound. Since the video is not reproduced while the vehicle is running, the driver of the vehicle does not watch the video and can ensure safety during driving. When the vehicle stops, it will be recorded And specified according to real-time audio playback Video Part of Therefore, the driver of the vehicle can effectively use a short stoppage time by paying attention to the portion to be seen determined from the result of listening to the audio reproduction in real time.
