The present invention relates to a multimedia system for a transportation device using a single communication line. More specifically, the tuner devices are installed in a structure independent from the head unit device, and the independent tuner devices are integrated and installed in close proximity to the antenna. And a head unit device are connected to a multimedia system for a transportation device via a single communication line.
운송장치용 멀티미디어 시스템이란, 자동차 등의 운송장치 내에서 멀티미디어 서비스를 제공하기 위해 설치되는 시스템으로서, 운송장치 내에서 카오디오 서비스, 동영상 서비스, 아날로그 방송 서비스, 디지털방송 서비스, 텔레매틱스(telematics) 서비스, 통신 서비스, 기타 서비스 등의 서비스들을 제공하기 위한 시스템이다. 이러한 운송장치용 멀티미디어 시스템은, 카오디오 시스템 등 다양한 형태로 구현될 수 있다. A multimedia system for a transportation device is a system installed to provide a multimedia service in a transportation device such as a car, and includes a car audio service, a video service, an analog broadcasting service, a digital broadcasting service, a telematics service, and a communication in a transportation device.

Therefore, the conventional multimedia system for a transportation device is based on the positional feature of the head unit device disposed in close proximity to the engine room of the transportation device (ex: automobile). There was a problem that the generated noise (field noise) easily affects the signal bands of the tuner devices installed in the head unit device, thereby reducing the reception sensitivity.
또한, 동축선로의 길이(약 5미터 내외)가 길어짐에 따라 선로 자체의 손실이 증가하고, 안테나와 헤드유닛 장치 튜너장치들과의 부정합 손실이 발생하여 신호의 수신감도가 저하될 수 있다는 문제점도 있었다.

그리고, 원거리에 배치되는 양 구성(안테나 / 헤드유닛 장치+튜너장치) 사이에 복수 개의 동축선로(복수 개의 튜너장치들의 다양한 신호를 위함)와 전원선(능동형 안테나의 경우)이 필요하므로, 시스템의 복잡성이 증가 되고, 각 동축선로의 노이즈 및 신호의 부정합 등을 독립적으로 관리해야 하며, 각 튜너 장치들을 통합적으로 제어하기 힘들다는 문제점도 있었다. In addition, a plurality of coaxial lines (for various signals of a plurality of tuners) and a power line (in the case of an active antenna) are required between two components (antenna / head unit device + tuner device) arranged at a long distance. The complexity is increased, and the noise and signal mismatch of each coaxial line must be managed independently, and it is difficult to integrate and control each tuner device.
