It is known.

[0003]

In the conventional optical disk reproducing system, when a user in a certain room instructs to reproduce a selected optical disk, the optical disk has already been instructed to be reproduced by a user in another room and is still reproducing. When, the reproduction instruction from the user in the certain room is canceled, and the user in the certain room cannot listen to the music.

An object of the present invention is to provide a disk reproducing system in which users in a plurality of rooms select and reproduce recording media stored in a common disk storage unit by remote control.
It is possible to appropriately cope with the case where the selected recording media overlap.

[0005]

The disk reproducing system (10) of the present invention has the following. (A) A disk storage unit (21) for storing a plurality of recording media (b) A recording medium can be sent and received between the disk storage unit (21) and the recording medium received from the disk storage unit (21) A plurality of reproduction units (22a, 22b) for reproduction; (c) reproduction media output units (38) arranged in each room; (d) each reproduction media output unit (38) is connected to the same reproduction unit (22a, 2).

Control means (20, 29) for controlling (32a, 32b) The control means (20, 29) controls a certain room (hereinafter referred to as “first
Room. " ) Instructs to select a reproduction recording medium, the recording medium has already been given a predetermined reproduction unit (38) for the reproduction media output unit (38) of another room (hereinafter referred to as "second room"). In the following, when the reproduction is being performed (hereinafter, referred to as “case 1”), the first reproduction unit and the reproduction media output unit (38) in the second room are connected. Connection switching means (32a, 3) so as to connect the first playback unit and the playback media output unit (38) in the first room while maintaining the connection of
2b) is controlled.

[0006] The recording medium is not limited to an optical disk such as a CD or DVD, but may be another recording medium such as a semiconductor memory. The medium to be played back by the recording medium is not limited to audio only, and may be both audio and video. The reproduction media output unit (38) is, for example, a speaker when the reproduction signal of the recording medium is only audio, and is a speaker and a monitor, for example, when the reproduction signal of the recording medium is both audio and video. is there.

[0007] In the disk reproducing system (10), the number of rooms in which the reproduction media output section (38) is provided is not limited to two. This disc playback system (10) is also applicable when the number of rooms in which the playback media output unit (38) is arranged is three or more. In addition, disc playback system (10)
Number of playback units (22a, 22b) and playback media output unit
The number of rooms in (38) may not be equal to each other.
The number of playback units (22a, 22b) in the disc playback system (10) may be smaller than the number of rooms in which the playback media output unit (38) is arranged. This is because there may be no user in all rooms. Further, users in three or more rooms can enjoy reproduction of the same recording medium. That is, in case 1, when the user in the third room further instructs the first and second room users to perform reproduction and selects and reproduces the recording medium being reproduced in the first reproducing unit. Assuming that the first room and the second room are the second room, and the third room is the first room, the control means (20, 29) may determine that the first room is the first room. While maintaining the connection between the playback unit and the playback media output unit (38) in the second room, the connection is established so as to connect the first playback unit and the playback media output unit (38) in the first room. Switching means (32a, 32
By controlling “b)”, the user in the third room before the replacement can also enjoy the reproduction of the recording medium being reproduced in the first reproducing unit.

When a user in the first room instructs to select a reproduction recording medium, the control means (20, 29) controls the recording medium even if the recording medium is already being reproduced for the user in the second room.
Are the first playback unit and the playback media output unit (3
As a result of controlling the connection switching means (32a, 32b) so as to connect the first playback section and the playback media output section (38) in the first room while maintaining the connection with the first section (8), the first The reproduction signal of the recording medium in the reproduction unit of the first embodiment is output from the reproduction medium output unit of the first room.
(38), and the playback media is output from the playback media output unit (38) in the first room. Thus, when the user in the first room instructs the selection of the reproduction recording medium, even if the recording medium is already being reproduced for the user in the second room, the user in the first room does not record the recording medium. You can enjoy playing the media.

According to the disc reproducing system (10) of the present invention, the control means (20, 29) sets the priority order in the first room and the second room, and sets the first order in the first reproducing unit.
In addition, with respect to a user instruction for a recording medium that is commonly reproduced for a user in the second room (hereinafter, referred to as a “first recording medium”), a part of a user instruction from a user in a lower priority room is limited. .

[0010] If there are instructions from the users in the first and second rooms for the first recording medium, the processing will be confused and trouble will occur. Therefore, priorities are set, and some user instructions are given. In this case, those from the user in the lower-priority room are limited, and the processing for the common selected recording medium can be performed without confusion.

[0011] According to the disk reproducing system (10) of the present invention, the user instruction partially restricted by the user in the lower priority room is all user instructions other than the recording medium selection instruction.

[0012] In this way, the user in the room with the higher priority order is not restricted with respect to the first recording medium.
The instruction is issued and executed, and the user in the room with the lower priority is allowed to instruct the selection of the recording medium, and the reproduction switching to the recording medium other than the recording medium being commonly reproduced is secured. In addition, to the user with the lower priority, the fact that his / her room is the room with the lower priority is
It is preferable that the information is displayed on a display unit arranged in the room together with the reproduction media output unit (38).

According to the disk reproducing system (10) of the present invention, the control means (20, 29) sets the first room lower in priority order than the second room.

[0014] Since the higher priority is given to the user who instructed the reproduction of the first recording medium first, the user who instructed the reproduction of the recording medium first gave the user instruction about the recording medium from the middle. Restricted and confused are prevented.

According to the disk reproducing system (10) of the present invention, in the case (1), when the recording medium switching instruction is issued from the second room in the case (1), the control means (20, 29) communicates with the first reproducing unit and the second reproducing unit. The connection between the first playback unit and the playback media output unit (38) in the second room is maintained while maintaining the connection with the playback media output unit (38) in the first room.

This ensures that the user in the first room can continue to enjoy the reproduction of the first recording medium while the first recording from the reproduction medium output section (38) in the second room. The reproduction output of the medium ends.

According to the disc reproducing system (10) of the present invention, in the case 1, when the recording medium switching instruction is issued from the second room, the control means (20, 29) The restriction of the user's instruction from is released.

When the user in the second room instructs switching to a recording medium other than the first recording medium, the user's instruction from the second room is different from that for a recording medium different from the first recording medium. Therefore, confusion of user instructions from the first room and the second room for the first recording medium does not occur. Therefore, the user of the first room is released from the restriction on the user instruction for the first recording medium, and various instructions for the first recording medium are enabled. The release of the user instruction for the first recording medium from the first room is displayed on the display unit in the first room, and the first instruction is displayed.
It is preferable to notify the user in the room of the user.

According to the disk reproducing system (10) of the present invention, when the control means (20, 29) receives an instruction to stop reproduction of the first recording medium from the second room in the case 1,
While maintaining the connection between the playback unit of the first room and the playback media output unit (38) of the first room, the connection between the first playback unit and the playback media output unit (38) of the second room is cut off. ing.

Thus, the user in the first room can read the first room
The reproduction output of the first recording medium from the reproduction medium output unit (38) in the second room can be ended while continuously enjoying the reproduction of the recording medium.

According to the disk reproducing system (10) of the present invention, in the case 1, when the reproduction stop instruction of the first recording medium is issued from the second room in the case 1, the control means (20, 29) The restriction of the user instruction from the lower room is released.

When the user in the second room instructs the reproduction stop of the first recording medium, the relationship between the user instruction from the second room and the first recording medium is the same as the user instruction from the first room. Since it becomes sufficiently thin compared to the relationship with the first recording medium, it is temporarily cut off. Then, by releasing the restriction on the user's instruction from the first room for the first recording medium, various instructions from the user of the first room for the first recording medium become possible. This is convenient for the user in the room. Note that the first recording medium
It is preferable that the release of the user instruction from the room is displayed on a predetermined display unit in the first room to notify the user in the first room.
