Some of the controls that may be provided are a contrast 48 that can control the contrast of video displayed on the screen 42 and a brightness 45 that can control the brightness of the picture shown on the screen 42. A power button 41 is used in order to turn the display device 40 on and off. The display device 40 may also be triggered to turn on when it receives video data from the media playback device 10.
The volume 43 may be an optional control that is used when the video input 46 is being used and is used to control the volume of audio that is produced by the display device 40. Alternatively, the volume 43 may control the audio in those instances where the audio is being transmitted from the multimedia player device 10 instead of being played through the vehicle's audio system.
For example, when a user of the multimedia player device 10 places a DVD disc into the slot 16 the optical disc player 73 will receive it. In a preferred embodiment, the optical disc player 73 is capable of playing both CDs and DVDs, in which case the optical disc player 73 first determines the format of the disc. When it is determined that a DVD disc has been placed within the optical disc player 73 the video and audio data read from the disc will be transmitted to the controller 72. When the video and audio data is received at the controller 72 it may be processed so that the data is split between the audio and the video data.
The video data will be sent to the transmitter 71, while the audio data is sent to the vehicle audio system 80 in order to provide audio throughout the vehicle. Preferably the video is transmitted at roughly 2.4 GHz to the display device 40. The vehicle audio system 80 may comprise pre-installed speakers in the vehicle, or speakers that have installed at some later point. In alternative embodiments that audio data may also be sent to the transmitter 71 for reproduction in the display device 40. If the audio data is transmitted to the display device 40 it may be transmitted at frequencies between 88.1-107.9 MHz or it may be transmitted at the same frequency as the video data.
