Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk reproducing apparatus, and more particularly, to a disk reproducing apparatus capable of reproducing a disk including a moving image such as a DVD video and continuing reproduction from a reproduction interruption position.

[0002]

2. Description of the Related Art Recently, DVDs have been used as disc-type storage media.
(Digital versatile discs) are attracting attention. This DVD has a diameter of 12 cm and a thickness of 1.2 mm. It has the same shape as a CD (compact disk), but achieves a storage capacity of 4.7 GB in a single layer and 8.5 GB in two layers by increasing the recording density. are doing. Also, MPEG
By adopting the image data compression technology and the audio data compression technology according to No. 2, various types of data are mixedly stored in the DVD. A DVD disk contains video and audio sources such as a movie and music karaoke, and a user can enjoy audio and video by using a disk device that reproduces these. CD audio, video CD,
There are also disc reproducing devices that can reproduce different types of discs such as a DVD video disc and a DVD audio disc with one reproducing device.

[0003] Some conventional disk reproducing apparatuses have a continuous reproduction function of storing a position at which reproduction of a disk is interrupted and performing subsequent reproduction from the reproduction interrupted position later. In particular, many disc reproducing devices mounted on a vehicle are provided with the continuous reproducing function, and the ACC of the vehicle is used.
The reproduction interruption position is stored in accordance with the turning off of the power supply (accessory power supply), and when the ACC of the vehicle is turned on later, the reproduction is continued from the stored reproduction interruption position.

[0004]

By the way, in the conventional continuous reproduction, when the power of the disk device is turned on, the reproduction is automatically started from the position where the previous reproduction was interrupted. In some cases, the video was played back while it was not prepared, and the video immediately after the playback was inadvertently missed. Depending on the source to be reproduced, the missed scene may be important for the subsequent scene, and the user may not be able to grasp the contents even if the reproduction is continued as it is. for that reason,
If the user has overlooked the video immediately after continuous playback, the user must operate the operation unit to return to the scene where the playback position was overlooked, which is troublesome.

When playing back a movie or the like recorded on a DVD video or the like, it is often the case that the connection to the place where the movie was played back last time is taken into consideration. At the time of reproduction, there was a case where it was not possible to grasp the connection between the story and the previous time. For this reason, the user has to perform an operation of returning the reproduction position to a position slightly before the position where the previous reproduction was interrupted, and an operation of confirming what the contents were up to that point, which is troublesome.

Particularly, in the case of a disk reproducing apparatus mounted on a vehicle, continuous reproduction is often performed, and it is troublesome to perform the operation of returning the reproduction position as described above each time. The position that was being played when the vehicle key was turned off is stored, and the next time the vehicle key is turned on, continuous playback from the stored playback interrupted position is performed. If the user starts the continuous playback immediately after turning on the key and turns on the key, the user may miss the video immediately after the continuous playback is started because the user starts the continuous playback before he or she is ready to watch the video. It is good if the missed video is not very relevant to the story, but if it is an important video, the user must operate the operation unit to return the playback position to the missed scene, which is troublesome. there were.
