         [0044]      FIG. 4  is a detailed block diagram of the selector  120  of the multimedia outputting apparatus. The selector  120  can be changed to have various constructions based on  FIG. 4 . Referring to  FIG. 4 , the selector  120  of the audio/video outputting apparatus includes a first switching unit  121  and a second switching unit  122 . The first switching unit  121  is provided for selecting a first multimedia signal among the multimedia signals outputted from the multimedia sources  111  to  114  and based on the first control signal outputted from the controller  150 . The first switching unit  121  outputs the selected first multimedia signal to the first display unit  130 . The second switching unit  122  is provided for selecting a second multimedia signal among the multimedia signals outputted from the multimedia sources  111  to  114  and based on the second control signal outputted from the controller  150 . The second switching unit  122  outputs the selected second multimedia signal to the second display unit  140 .  
         [0045]     Accordingly, the first multimedia signal of the telematics terminal inside the vehicle is outputted to the first display unit and the second multimedia signal is outputted to the second display unit. Passengers seated in different seats, e.g., such as in the front seat and in the rear seat of the vehicle, can independently watch each different multimedia.  
         [0046]     An exemplary method for outputting audio/video signals outputted from the multimedia outputting apparatus of the telematics terminal will be described with reference to FIGS.  3  to  5 . In the following exemplary method, the first and second multimedia signals are first and second audio/video signals, e.g., containing both audio and video information.  
         [0047]      FIG. 5  is a flow chart of a process for outputting audio/video signal(s) from the telematics terminal. First, when a user(s) selects specific multimedia signals by using a select button (not shown) or a remote controller (not shown) for selecting a specific multimedia, the controller  150  outputs a first control signal for selecting a first multimedia signal and a second control signal for selecting a second multimedia signal according to the users&#39; request(s). The controller outputs the first control signal to the first switching unit  121  and the second control signal to the second switching unit  122 .  
         [0048]     For example, when the TV tuner  112  is selected by the passenger in the front seat of the vehicle, the controller  150  outputs the first control signal for selecting the TV broadcast signal (the first multimedia signal) outputted from the TV tuner  112  to the first switching unit  121 . When the CD/DVD processing unit  111  is selected by the passenger in a rear seat of the vehicle, the controller  150  outputs the second control signal for selecting the CD audio/video signal (the second multimedia signal) or the DVD audio/video signal (the second multimedia signal) outputted from the CD/DVD processing unit  111  to the second switching unit  122 .  
         [0049]     The first switching unit  121  selects the TV broadcast signal outputted from the TV tuner  112  based on the first control signal, and outputs the selected TV broadcast signal to the first display unit  130  (step S 11 ). For example, the first display unit  130  is installed at the front side of the telematics terminal in the vehicle and displays a video signal contained in the TV broadcast signal selected by the user, e.g., the driver or the passenger next to the driver (step S 12 ). A speaker installed at the first display unit  130  outputs an audio signal in synchronization with the video signal contained in the TV broadcast signal.  
         [0050]     The second switching unit  122  selects a CD audio/video signal or a DVD audio/video signal outputted from the CD/DVD processing unit  111  based on the second control signal, and outputs the selected CD audio/video signal or the DVD audio/video signal to the second display unit  140  (step S 13 ). The second display unit  140  is installed at the rear side of the front seat so that the passenger seated in the back seat of the vehicle can watch desired multimedia, and displays a video signal contained in the CD audio/video signal or the DVD audio/video signal selected by the user, e.g., the passenger in any rear seat, (step S 14 ). In addition, a second speaker is installed at the second display unit  140  and outputs an audio signal in synchronization with the video signal contained in the CD audio/video signal or the DVD audio/video signal. The first and the second display units may be provided in numerous predetermined positions throughout the vehicle, such as one or more or both display units being disposed in rear seats, on window visors, or in front seats. The individual display units may include the first and the second speakers which include audio output(s) permitting the use of headphones for listening to audio content privately at the first and/or the second display units, and/or input ports for peripheral devices such as interactive gaming devices and controllers.  
         [0051]     The first display unit  130  and the second display units may include any video display. However, LCDs (Liquid Crystal Displays) are used as the first display unit  130  and second display unit  140  in one embodiment. In addition, the first display unit  130  and/or the second display unit may include individual controllers so that content selection can occur locally at the display unit. For example, a display unit positioned in a rear, third row seat can be provided with a controller supporting content selection, such as multimedia content selection, and/or use as a game console and controller.  
         [0052]     The foregoing apparatus and method for outputting multimedia provide one or more advantages. By outputting the first multimedia signal of the telematics terminal inside the vehicle to the first display unit and outputting the second multimedia signal of the telematics terminal to the second display unit, the passengers in separate seats, e.g., in the front seat and the back seat of the vehicle, can independently watch different multimedia.  
         [0053]     The selective use of content for individual display units can be provided for a variety of multimedia modules producing or reproducing multimedia signals from a telematics terminal, or from stand-alone multimedia devices within a vehicle.  
         [0054]     It should be understood that the above-described embodiments are not limited by any of the details of the foregoing description. Accordingly, other implementations are within the scope of the following claims.
