BACKGROUND OF THE INVENTION
The present invention relates to an optical disc playback apparatus that plays back information recorded on an optical disc, and in particular, has a so-called last memory function that enables playback from the continuation of playback stop when playback is resumed even if the optical disc is stopped during playback. The present invention relates to an optical disc reproducing apparatus.
[0002]
[Prior art]
Conventionally, an optical disk reproducing apparatus reproduces a large-capacity optical disk such as a DVD (digital versatile disk) and is used for reproducing a soft disk such as a long movie. In this movie soft disk, the main information signal is usually used as one title, which is divided into a plurality of chapters. In addition to this bias, the movie soft disk includes a setup screen, a menu screen, a production company logo screen, a commercial screen, and a copyright notice screen.
[0003]
In the optical disk playback device, when the playback is temporarily stopped by the user's operation during the playback of the optical disk, and then playback is started, it returns to the initial playback start state, and the logo image or copyright of the production company is returned. After the video such as this notice is played, the video of this bias is played. Therefore, if you want to watch the video from where you last stopped playback, you need to fast-forward while watching the playback video and look for the location where playback stopped last time. There is a problem that it takes a lot of operations and time.
[0004]
Therefore, an optical disc playback apparatus (for example, a DVD playback apparatus of Patent Document 1) having a so-called last memory function (also referred to as a resume function) capable of automatically searching for a location where playback was stopped last time and continuing playback can be developed and put on the market. It is circulating. In such an optical disc playback apparatus having a last memory function, when playback stops while playing an optical disc, the playback stop position address information, playback environment information, the time from playback start to playback stop, playback stop date and time, When the last memory information including the disk specific information is stored in the memory and then the reproduction is started again, the reproduction is started from the point where the reproduction is stopped based on the last memory information stored in the memory. In other words, this optical disk playback apparatus can automatically search for the location where playback was previously stopped and continue playback.
[0005]

Japanese Patent Laid-Open No. 2002-133828 [0006]
[Problems to be solved by the invention]
By the way, for example, since user A has been able to do another task, he / she appreciates the information recorded on the optical disc a halfway, and once the reproduction is stopped, the last memory information at the time when the reproduction is stopped is stored in the memory. Next, the user B inserts an optical disk b different from the optical disk a into the optical disk reproducing apparatus, and reproduces the optical disk b. Then, since the optical disk a that the user A is watching is different from the optical disk b that the user B wants to watch, if the playback of the optical disk b is stopped halfway, the last memory information in the memory for the optical disk a is the optical disk b. Overwritten with last memory information for.
[0007]
Therefore, when the user A wants to watch the optical disk a after the user B views the optical disk b, the last memory information for the optical disk b that the user B was watching is stored in the memory. The user A can no longer reproduce the optical disc a for which reproduction has been interrupted. That is, in the conventional optical disk reproducing apparatus, the last memory information for the optical disk for each user cannot be stored. Therefore, when the reproduction is stopped after the reproduction is stopped in the middle of the reproduction, the optical disk of the same user can be used. Instead, if a different optical disc is played, the optical disc for the previous user can be played from the beginning after this, but if you want to play from the previous continuation, you cannot automatically play from the continuation, the last last time. Therefore, there is a problem that it takes a lot of operations and time to search for the playback portion that was being viewed.

[0027]
Here, the characteristic operation of the present embodiment will be described with reference to FIGS. In this description, for example, user A sets his / her identification information to “1234”, and this identification information is input on the user registration screen as shown in FIG. 3 and registered in the memory 16 by the user registration means 120. Shall. Then, the operation after the user A stops reproducing while the optical disk a is being reproduced, taken out from the apparatus, and the user A inserts the optical disk a into the optical disk reproducing apparatus again will be described. When the reproduction of the optical disc a is stopped, the last memory information including the address information of the reproduction stop position regarding the optical disc a, the title, chapter and time, the disc unique information, the audio number, the subtitle number, the angle number, etc. at the time of the reproduction stop. It is assumed that the memory 16 is set.
[0028]
When the user A inserts the optical disk a whose reproduction has been stopped into the optical disk reproducing apparatus again (step S1), a user selection screen as shown in FIG. 2 is displayed on the display device 13 (step S2). Then, the user A looks at the user selection screen and sees whether or not his / her identification information “1234” is present (step S3). If there is no identification information, the user A displays “user registration” on the user selection screen. 3 is displayed on the display device 13 as shown in FIG. 3 (step S4).
[0029]
When the user registration screen is displayed, the user A inputs, for example, “1234” as his / her identification information. Thereby, the user registration means 120 registers the “1234” in the memory 16 as the identification information of the user A (step S5). Thereafter, the user selection screen is displayed again (step S2).
[0030]
However, since the identification information “1234” of the user A is registered in the memory 16 before the optical disk a is first played back, the user selection screen has the identification information “1234”. (Step S3), the user A selects the identification information “1234” (Step S6). If the last memory information is set in the memory 16 (Step S8), the identification information of the optical disc A is stored in the last memory information. It is determined whether or not it matches the disc-specific identification information (step S9). If the two pieces of identification information match, a reproduction location selection screen as shown in FIG. 4 for inquiring to the user A whether to reproduce from the reproduction position set in the last memory information is displayed (step S10).
[0031]
Next, it is determined whether or not there is an input for reproduction from the reproduction position set in the last memory information (step S11). That is, when the user A selects the item “play from the continuation” on the playback location selection screen, it is determined that there is an input for playback from the playback position set in the last memory information. Playback is started based on the address information of the playback stop position and playback environment information (step S12). Then, when the reproduction is finished to the end (step S14), this process ends.
[0032]
In step S6, if the user is not selected, if “NO USER” on the user selection screen shown in FIG. 2 is selected, the last memory determination unit 123 next determines whether or not the last memory information is set in the memory 16. Is determined (step S7). If the last memory information is set, the process proceeds to step S9 and the same processing is performed. If the last memory information is not set, normal reproduction is started (step S13). Then, when the reproduction is finished to the end (step S14), this process ends. The user identification information may be a name or a symbol.
[0033]
In the above description, when the user A inserts the optical disk a into the optical disk playback apparatus and plays back the optical disk a, the user A's identification information “1234” is registered, and the playback of the optical disk a is stopped halfway. If the last memory information for “a” is set in the memory 16 and the user A desires to reproduce the optical disk “a” again, the optical disk is determined based on the identification information “1234” of the user A and the last memory information for the optical disk “a”. a can be reproduced continuously. However, when the user B's optical disk b is reproduced continuously, the user C's optical disk c is reproduced continuously, etc., depending on the identification information and the last memory information. The optical disks b and c can be reproduced from the next.
[0034]
As described above, the operation of stopping the playback of the optical disk during playback, taking it out from the apparatus, inserting the optical disk into the optical disk playback apparatus again, and continuing playback has been described. The same applies to the operation when the apparatus is turned off and playback is stopped halfway, and the power is turned on again and the optical disk is played back continuously.
[0035]
