Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a recording / reproducing method and apparatus for video signals and audio signals, and more particularly to an apparatus using a disc-shaped recording medium, which can be reproduced by a conventional video / audio reproducing apparatus, a so-called DVD video player. The present invention relates to a recording / reproducing method and apparatus for a recording medium.
[0002]
[Prior art]
Recently, a recording / reproducing apparatus for encoding a video signal and an audio signal and recording them on a recording medium such as a disk has been proposed. Such a recording / reproducing apparatus encodes a video signal and an audio signal, respectively, to form one time-division data string, and records access information for access control as another data string.
At the time of reproduction, a data string is read in advance for access control, and the time division data is separated into a video signal and an audio signal and reproduced in synchronization with each other.
[0003]
On the other hand, a read-only device that reads and plays back video and audio signals from disk media separates the access information, video and audio signals recorded in a time-sharing manner and plays them in synchronization ing.
[0004]
[Problems to be solved by the invention]
However, as described above, the structure of the time division data is different between the recording / reproducing apparatus and the reproduction-only apparatus.
In particular, since access information for access control is different data or inserted into time-division data, video / audio data recorded by the recording / reproducing apparatus cannot be reproduced by the reproduction-only apparatus.
Reproduction-only data structure In the so-called DVD video standard, access control data (NAV pack) is inserted in time-division data, but the data position from the past to the future is based on the reproduction point. (See FIGS. 3 to 6).
[0005]
If the compression rate of the video signal is fixed, it is possible to predict a data position that has not yet been recorded, and it is possible to insert access control data (access information).
However, in order to efficiently use the limited disk capacity to the maximum extent, it is necessary for the encoding of the video signal to have a variable compression rate in accordance with the characteristics of the input video signal. That is, when the compression rate is variable, the future data position cannot be predicted.
For this purpose, a data structure for recording and reproduction, the so-called DVD video recording standard, has been created.
[0006]
In this DVD video recording standard, access management information (access information) is managed as separate data. During recording, the access information is stored until encoding of the video / audio signal is completed, that is, until recording is stopped. In addition, after the encoded data is recorded on the disc, the access information is recorded on the disc on which the encoded data is recorded.
At the time of reproduction, the access information is read in advance, and the video / audio signal is decoded and reproduced.
[0007]
As described above, since the method of managing access information for access differs between the DVD video standard and the DVD video recording standard, the video / audio data recorded on the recording medium by the recording / reproducing apparatus is reproduced by the reproduction-only apparatus. There is a problem that cannot be done.
In order to solve the above-described problems, the present invention provides an apparatus capable of recording video / audio data in accordance with a DVD video standard format that can be reproduced by a conventional DVD player.

The encoded audio data is decoded by the audio decoding circuit 8 to obtain an audio signal, and the audio output circuit 9 outputs the audio.
[0017]
When a random access command is received during playback, that is, when the playback position is moved back and forth, the access destination of the optical disc 1 is determined using the access information of the NAV pack. If there is no mark that the data position has not yet been determined, that is, in the case of the NAV pack in which the access information is correctly recorded, the CPU (10) receives the access information as it is from the NAV pack recorded in the optical disc 1.
[0018]
If there is a mark in the access information of the NAV pack that a valid data position in the future direction has not yet been determined, access in the future direction is obtained by calculating the access information stored in the memory circuit 11. .
In this state, the data recorded on the optical disc 1 does not yet satisfy the DVD video standard, and the optical disc 1 cannot be taken out from the recording / reproducing apparatus.
[0019]
The operation when the recording / reproducing apparatus of the present invention is neither recording nor reproducing, or when a request for taking out the optical disc 1 is generated will be described.
The CPU (10) checks whether access information remains in the memory circuit 11. If access information still remains, the access data of the NAV pack on the optical disc 1 is not valid.

[0021]
When the CPU (10) outputs valid NAV pack data whose desired data position is determined, the CPU (10) deletes information indicating the access position from the memory circuit 11.
This NAV pack generation operation is continuously repeated until the memory circuit 11 becomes empty.
Only when the memory circuit 11 is empty will the data recorded on the optical disc 1 satisfy the DVD video standard.
[0022]
(Second embodiment)
Next, a second embodiment of the recording / reproducing apparatus of the present invention will be described with reference to FIG. The block configuration of the second embodiment of the recording / reproducing apparatus of the present invention will be described below with reference to FIG.

At that time, the farthest data position referenced from the NAV pack of the first recorded VOBU is determined (see FIG. 6).
[0042]
The NAV pack correction operation is started from that point.
That is, the CPU (10) calculates each address from the access information stored in the memory circuit 11, and generates regular NAV pack data.
The new regular NAV pack is overwritten and recorded at a corresponding position on the disk 1 by the recording head 21 via the recording circuit 20.
[0043]
When the CPU (10) outputs valid NAV pack data, the access information indicating the access position is deleted from the memory circuit 11.
During the recording of video and audio, the above NAV pack generation operation is repeated each time the amount of access information stored in the memory circuit 11 is stored in 240 VOBU.
[0044]
After the video and audio recording ends, the CPU (10) continues the above NAV pack generation operation until the memory circuit 11 becomes empty.
