The present invention includes a plurality of speakers, at least one front monitor and one rear monitor, and a DVDP for reproducing audio and video data recorded on a DVD, VCD and CD, and a TV for receiving audio and video data. A control unit of a vehicle AV system comprising a processor and a radio processor for receiving audio signals and reproducing audio data. The present invention relates to a control unit of a vehicle AV system, and in particular, a video signal and audio reproduced from each of the reproduction units. By switching the signals and outputting them to the speakers corresponding to the front monitor, the rear monitor, and the monitor on which the corresponding video is output, a single channel of the system can simultaneously drive individual modes performed by each playback unit in the system. Mode simultaneous drive control unit and its control method One will.

AV system is generally DVD, VCD, DVDP which plays audio and video data recorded on CD, TV processor which receives TV signal and plays audio and video data, and radio processor which receives audio signal and plays audio data. Since it is configured to include, it becomes a multi-channel in the sense that it can perform a plurality of individual modes.

By driving the DVDP, the TV processor, and the radio processor, the user can watch the video and audio played in each individual mode to be watched through the monitor and the speaker.

The conventional AV system did not need to watch TV news or radio broadcasts simultaneously while watching DVDs, so only one mode is performed at a time in its function.

That is, in the conventional AV system, any other playback unit cannot be driven while any of the DVDP, the TV processor and the radio processor is being driven. If the TV broadcast is desired while watching a DVD, the DVDP is stopped. The TV processor can be driven to watch TV broadcasts.

FIG. 5 is a block diagram showing a driving method of a plurality of display units of a multi-channel AV system according to the related art. As shown in FIG. 5, the conventional multi-channel AV system drives each function sequentially or alternately in order to perform different individual modes through one display unit.

Initially, all passengers watched images through the front monitor installed in front of the vehicle and listened to the audio from the speaker system inside the vehicle.However, in order to provide good audiovisual for the passengers in the rear seats, rear monitors were also installed in the rear seats. The same image as the monitor was aired.

This is illustrated in FIG. 6. FIG. 6 is a block diagram illustrating a sequential individual mode driving method of a multi-channel AV system according to the related art. FIG. 6 illustrates a conventional method in which an image signal controller controlled by a system controller outputs the same image signal to a plurality of display units. have.

However, for a variety of convenient uses of the multi-channel AV system, there is an increasing demand to simultaneously play individual modes by multiple driving of different playback units in an AV system.

As an example, in a vehicle AV system, passengers in the front seats want to watch a DVD and passengers in the back seats want to watch TV broadcasts.

In this case, two AV systems were required to drive the video signal output through the front monitor, the video signal output through the rear monitor, and the corresponding audio signal to perform each individual mode.

Therefore, there is a serious problem that the unevenly installed AVs play additional costs of the regeneration units and the speaker system of the system, and the various needs of the user act as an economic burden on the user.

In particular, in step 419 of FIG. 3, a multi-channel AV according to the present invention sets a playback unit in the rear monitor 320 for individual mode simultaneous driving control of the system. As shown in FIG. 2, when the Main menu is displayed on the screen, the cursor is placed on the rear monitor using the up and down navigation keys, and the confirmation key is pressed to move to the Rear menu. It is set by setting the rear monitor to any one of DVD, radio, TV, AV1, AV2, and OFF using the up and down navigation keys in the rear menu.

Hereinafter, a method of controlling individual mode simultaneous driving of a multi-channel AV system according to the present invention will be described in detail with reference to FIGS. 1 and 4.

4 is a control flowchart illustrating a method for controlling individual mode simultaneous driving of a multi-channel AV system according to an exemplary embodiment of the present invention, and shows a method for controlling individual mode simultaneous driving of a multi-channel AV system by the microcomputer 110.

First, as shown in FIGS. 2 and 3, in the case where a playback unit to be output to the rear monitor 320 is set among the DVDP 140, the TV processor 220, and the radio processor 230, FIG. 4. As shown in FIG. 2, the microcomputer 110 drives an arbitrary playback unit according to a user's key input in operation 501, and the audio and video data reproduced through the optional playback unit is changed in step 503. Through the front monitor 310 to output.

In this case, when the rear monitor 320 is open (step 505), the microcomputer 110 determines whether there is a playback unit in which the rear monitor 320 is set (step 507), and the set playback unit is currently driven. In step 509, it is determined whether or not there is a playback unit.

If there is no playback unit set in the rear monitor 320 in step 507, the process proceeds to step 511 and outputs an image currently being played back to the rear monitor 320. In operation 509, if the playback unit set in the rear monitor 320 is a driving unit that is currently driven, the process proceeds to step 511 and outputs an image currently being played back to the rear monitor 320.

On the other hand, if it is determined in step 509 that the playback unit set in the rear monitor 320 is not currently being driven, the process proceeds to step 513 where the DVDP 140, the TV processor 220 and the radio processor 230 are operated. The driving unit set in the rear monitor 320 is driven to switch the video signal reproduced from the playback unit set in the rear monitor 320 to the rear monitor 320, and the audio signal is switched to the rear speaker. Let the output.

In addition, the individual mode simultaneous drive control method of the multi-channel AV system according to the present invention, the rear monitor 320 of the DVDP 140, the TV processor 220, the radio processor 230 during the driving of any playback unit is opened. If there is a signal input, by displaying a signal identifying the playback unit to be output to the rear monitor 320 of the DVDP 140, TV processor 220, radio processor 230 on the rear monitor 320, the user The DVDP 140, the TV processor 220, and the radio processor 230 may reset the playback unit to be output to the rear monitor 320.

As described above, the method for controlling individual mode simultaneous driving of a multi-channel AV system according to the present invention simultaneously allows the multi-channel of the system to be divided into individual modes so that AV can satisfy various needs of users who want to simultaneously enjoy the multi-channel of the system. I can drive it.

On the other hand, in the detailed description of the present invention has been described with reference to specific embodiments, of course, various modifications are possible without departing from the scope of the invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.

As described above, the present invention has the advantage that the AV can simultaneously drive the multi-channel of the system in a separate mode to satisfy the various needs of users who want to enjoy the multi-channel of the system at the same time.

In addition, the present invention can simultaneously drive the multi-channel provided by the system in a single mode using a single AV system, so that redundantly installed AV can remove various functions at a low cost by eliminating the playback unit and speakers of the system. There is an effect that can be used at the same time, there is an advantage that can effectively use the existing system.
