The switching request recognition unit 622A recognizes a switching request signal for switching the playback terminal device 400 to be operated based on the operation signal from the operation unit 610. Specifically, the switching request recognition unit 622A Then, the presence / absence of a switching request signal due to a pressing operation on the touch panel of the display unit 200 is recognized.
When the switching request recognition unit 622A recognizes the switching request signal from the operation unit 610, the switching request recognition unit 622A outputs a confirmation signal to that effect to the source switching unit 622B.

When the source switching unit 622B recognizes the confirmation signal indicating that the switching request signal from the switching request recognition unit 622A has been recognized, the source switching unit 622B switches to a state in which the playback terminal device 400 different from the currently operating playback terminal device 400 is operated. do.
Specifically, when the source switching unit 622B recognizes the confirmation signal based on the switching request signal corresponding to the pressing operation of the switching button of the operation unit 610, the source switching unit 622B selects the playback terminal device 400 that is currently selected and operated. to decide. That is, a radio tuner unit 410 for AM processing, a radio tuner unit 410 for FM processing, a TV tuner unit 430, a CD / DVD player 420 with a CD mounted thereon, a CD / DVD player 420 with a DVD mounted thereon, It is determined whether it is the MSV processing unit 440.
Then, the source switching unit 622B switches to another playback terminal device 400 that is different from the playback terminal device 400 currently operating. As the switching to the other reproduction terminal device 400, the switching is performed in the order according to the order information 710 stored in the memory 621 as described above.
In this switching process, power supply to the playback terminal device 400 that is currently operating is cut off, and power is supplied to the playback terminal device 400 in the next sequence to be operated.
Further, when the source switching unit 622B recognizes a confirmation signal based on the switching request signal corresponding to the operation of the touch panel of the display unit 200, the source switching unit 622B switches to a state in which the predetermined playback terminal device 400 operated by the touch panel is operated. That is, the touch panel is operated in accordance with a predetermined icon 701 in the touch panel source selection screen 700 displayed on the display unit 200 as shown in FIG. 2, and the playback terminal device 400 corresponding to the touched icon 701 is displayed. A switching process for operating the corresponding playback terminal device 400 is performed by a confirmation signal based on the switching request signal for switching to the operating state.

In addition, when the source switching unit 622B recognizes that the playback terminal device 400 is not operating at the present time, for example, immediately after the supply of power, for example, immediately before the supply of power is stopped by the supply of power before the power is turned on. It is searched for which playback terminal device 400 that was operating in the memory 621 is stored in the memory 621. Then, when the playback terminal device 400 that has been operating in the past is recognized, a setting is made to operate the previous playback terminal device 400. In addition, for example, when the playback terminal device 400 that has been operating before the memory 621 is not stored, such as in an initial state, for example, processing for performing AM processing in the radio tuner unit 410 that is the first order of the first group do.
For example, the touch panel source selection screen 700 as shown in FIG. 2 may be displayed.

The disc discriminating unit 622C operates as an audio system with music data recorded on a CD / DVD player 420 without including video data and mounted with a CD, or operates as a video system with a DVD including video data mounted, for example. Judgment is made. That is, when operating as an audio system, for example, processing of displaying predetermined image data stored in the memory 621 and displayed on the screen of the display unit 200 is different in processing contents between the audio system and the video system.
Specifically, the disc determination unit 622C determines whether the disc-shaped recording medium mounted on the CD / DVD player 420 that can function in both the audio system and the video system is a CD or a DVD. Determine whether. When a CD is loaded, it is determined as an audio system, and when a DVD is loaded, it is determined as a video system, and the fact is output to the source switching unit 622B.

Guide guidance means 622D calculates the current position and traveling direction of the vehicle on separately acquired map information based on the detection signal from each sensor in the sensor unit 500, GPS data, etc., and the current position and traveling on the map. Recognize direction.
Further, for example, the guidance means 622D acquires destination information related to a destination set and input by an input operation of the operation unit 610, setting item information for setting and inputting a route, and map information. The route search is performed by calculating the movement route. This route search is based on the setting item information, whether it takes into account VICS data, which is traffic information such as traffic regulation, traffic jams, traffic jam prediction, etc., and requests for various route searches such as the shortest distance and the shortest time. Based on this, the travel route is calculated.
Then, based on the map information, VICS data, and the like, the guidance and guidance unit 622D uses the display unit 200 and the speaker 300 to drive the vehicle such as information such as guidance for moving conditions and movement, traffic information, and details of the facility. Generate guidance information for support. As this guidance information, for example, “700m ahead, the XX intersection is in the right direction in the direction of △△”, “Departed from the movement route”, “This is a traffic jam,” and so on. Information for controlling the display unit 200 to display image data in the guidance information on the screen of the display unit 200, for example, displaying a predetermined arrow or symbol on the screen.

  The display control unit 622E reads out image data as appropriate from the memory 621 based on a control signal output from the source switching unit 622B, the guidance unit 622D, and the like, and displays the image data on the display unit 200. Examples of the image data to be displayed include a touch panel source selection screen 700, map information, a content processing state in the playback terminal device 400, a screen for prompting an input operation for various setting inputs, and a display unit 200 during audio processing. Examples include predetermined image data to be displayed on the screen, menu screens, and the like.

  The time measuring means 622F recognizes the current date and time based on a reference pulse such as an internal clock. And this time measuring means 622F suitably outputs the time information regarding the recognized current date and time.

[Operation of playback system]
Next, the operation of the reproduction system 100 in the above embodiment will be described with reference to the drawings.

First, when power is supplied to the playback system 100, the calculation unit 622 of the playback device 600 performs a process of causing the display control unit 622E to display the menu screen stored in the memory 621 as an initial state on the display unit 200 and use it. It becomes the input standby state of the operation setting by the user. Each of the connected playback terminal devices 400 enters an operable operation standby state by an operation setting input operation by the user.
Further, the calculation unit 622 acquires date and time information from the memory 621 and time information from the time measuring unit 622F as processing in the processing state by the source switching unit 622B. In addition, when the process for supporting driving of the vehicle has already been performed by the guidance guide unit 622D, that is, when GPS data is acquired, time information included in the GPS data is acquired. Then, the source switching unit 622B searches for the presence / absence of date / time information in which the current date / time of the time information has passed the date / time at which the period information of the date / time information is canceled. For example, the read date and time information is “2011/07/07/01” corresponding to 0:00 on July 1, 2011 when the distribution of the terrestrial analog TV broadcast wave is stopped and the specific information corresponding to the TV tuner unit 430. If the current time is past 0:00 on July 1, 2011, date / time information corresponding to the TV tuner unit 430 is detected.
If there is no date / time information indicating that the current date / time has passed, the input standby state is maintained.

  On the other hand, when the date / time information whose current date / time has already passed is detected by the search, the source switching unit 622B recognizes the playback terminal device 400 that is not operated, for example, the TV tuner unit 430, based on the specific information of the date / time information. . Thereafter, as illustrated in FIG. 3, the source switching unit 622 </ b> B performs processing for removing the television tuner unit 430 in the order information 710 stored in the memory 621 from the order. As this process, for example, in addition to the process of directly changing the order information 710 such as deleting the next process of operating the TV tuner unit 430, or associating the flag information with a state of skipping the order, For example, prohibition information that is not operated in a state where the operation of switching to the tuner unit 430 is not performed is separately generated and stored in the memory 621.

Further, the source switching unit 622B performs a process of not displaying the icon 701 corresponding to the TV tuner unit 430 from the touch panel source selection screen 700 as shown in FIG. 2 in combination with the process of removing the TV tuner unit 430 from the order.
As this processing, for example, when the touch panel source selection screen 700 is displayed by the display control means 622E, the flag information is not associated with the icon 701, or the same pattern as the background is displayed in a state where it is not substantially displayed. An example of processing such as superimposing and displaying is possible.

In addition, the source switching unit 622B sets the television tuner unit 430 to be operable again by an input operation of the operation unit 610 as a handling of the external input device in combination with the process of removing the television tuner unit 430 from the order. A setting screen for prompting an input operation is created. In other words, a setting screen as shown in FIG. 4 is created for enabling the TV tuner unit 430 set to a state in which it is not automatically operated by the source switching unit 622B to be manually operable again by an input operation.
Specifically, if the current date and time has not reached 0:00 on July 1, 2011, for example, a setting input screen 720 shown in FIG.

[Effect of playback system]
As described above, in the above embodiment, the playback device 600 to which a plurality of playback terminal devices 400 that process content data such as audio data and video data are played back is connected to a user input operation in the operation unit 610. When the switching request recognition unit 622A recognizes the switching request to switch to any one of the playback terminal devices 400, the source switching unit 622B operates another playback terminal device 400 that is different from the playback terminal device 400 currently operating. The source switching unit 622B is stored in the memory 621 and is based on the date / time information related to the date and time when the television tuner unit 430, for example, the television tuner unit 430 stops the reproduction process of the television broadcast. The other playback terminal device 400 to be switched is subject to the content data processing cancellation In the case of a certain TV tuner unit 430, the current date and time measured by the time measuring unit 622F and the current date and time included in the GPS data acquired for driving support by the guidance guiding unit 622D have passed the date and time when the date and time information is canceled. Upon recognition, the TV tuner unit 430 which is another playback terminal apparatus 400 to be switched is not operated, and a process of switching to a state where the other playback terminal apparatus 400 such as the CD / DVD player 420 is operated is performed.
For this reason, for example, after the distribution of the terrestrial analog television broadcast that has been recognized in advance, the television tuner unit 430 does not automatically operate based on the date / time information stored in the memory 621 in advance. By switching to the TV tuner unit 430, unnecessary consumption of power, such as processing of radio waves in a frequency band that is not distributed, can be prevented, and complicated operations such as a user entering settings to prevent switching to the TV tuner unit 430 Can be prevented. Therefore, it is easy to use and unnecessary power consumption can be prevented.

And whenever it recognizes the switching request | requirement by the input operation of the user in the operation part 610, the order information 710 regarding the order of the reproduction | regeneration terminal device 400 operated next is memorize | stored in the memory 621, and the order information 710 of the order information 710 is stored by the source switching part 622B. The playback terminal devices 400 that are operated according to the order are sequentially switched.
Therefore, the next playback terminal device 400 is operated based on the order information 710 with a simple configuration that stores the order information 710 without performing processing such as recognizing the playback terminal device 400 currently operating. Therefore, it is easy to speed up the process and provide better utilization.

Processing is done so that it is not displayed.
For this reason, in the configuration in which the process of switching to the playback terminal device 400 that operates by operating the touch panel according to the screen display by the display unit 200 is performed, there is no discrepancy between the display content and the setting content by the source switching unit 622B. Can be improved.

Further, the source switching unit 622B prompts an input operation for setting the operation state again by the input operation of the operation unit 610 corresponding to the playback terminal device 400 set to the non-operation state based on the date and time information. The setting input screen 720 is produced so that the display control means 622E can display the screen.
For this reason, for example, even in the playback terminal device 400 set to a state in which the operation is not performed based on the date / time information, the distribution of the terrestrial analog TV broadcast wave is started again or the date / time when the distribution is stopped is postponed, Even if inconvenience such as the inability to reproduce occurs, it can be operated again manually by the setting input screen 720, and versatility can be improved.

Furthermore, the period information in the date / time information can be changed by an input operation.
For this reason, even if inconveniences such as the date and time when the distribution is canceled and the television broadcast cannot be reproduced, the inconvenience such as the inability to reproduce the television broadcast can be prevented by resetting the date information again. it can.

Then, the source switching unit 622B performs a process of cutting off the supply of power to the target playback terminal device 400 as a state in which the source switching unit 622B is not operated.
This further prevents unnecessary power consumption.

In addition, as the current date and time, the time information included in the GPS data used in the processing for driving support by the guidance guide unit 622D can be acquired and recognized.
For this reason, even if it does not have the structure which time-measures the present date and time, such as the time measuring means 622F, the present date and time can be recognized, and simplification of a structure can be achieved easily.

Then, as the order information 710 for setting the playback terminal device 400 to be operated, the AM process and the FM process are made continuous, and the order in which the CD process and the DVD process are made continuous is set.
Therefore, the switching of the playback terminal device 400 is performed only four times: radio tuner unit 410 → TV tuner unit 430 → CD / DVD player 420 → MSV processing unit 440 → radio tuner unit 410, and the processing can be further speeded up. Is obtained.

Since the arithmetic unit 622 is configured as a program using, for example, a CPU, it is easy to configure the program by installing the program so that unnecessary power consumption is prevented and switching of the playback terminal device 400 is easy to use. And can be used easily.
The calculation means in the present invention is not limited to a single computer, but a configuration in which a plurality of computers are combined in a network, an element such as a CPU or a microcomputer as described above, or a circuit on which a plurality of electronic components are mounted.
