Description of the Invention: [Technical Field] The present invention relates to a medium connection and a system using the medium connection device, which is used as a medium between a media player and an audio device The media player is controlled by the user's manipulation of the audio device, which packet processing is performed on the audio signal reproduced by the media player' and the audio signal is hierarchically provided to the audio device so that the sound can be output from the audio device. [Prior Art] Media players such as MP3 players or voice recorders have been widely used, and these media players reproduce and record media slots. The first figure is a functional block diagram schematically showing the configuration of a conventional media player. The conventional media play H(1) has a nonvolatile storage device (5) such as a flash in it, so that the media_ received via the external host device (7) of the network can be stored in the storage. When a reproduction command is input through the user interface (UI) module, the storage device (5) reads the media, and weave the device (6) to the device (6). Then, the media player (1) performs signal processing in accordance with a predetermined signal processing scheme such as a 舯阢-丨 layer. In order to transmit and receive media tags, the host device (7) and the media (1) have a transmission medium connection function. The first figure shows an example of using a two-string bus. In the _ technology, when two devices = connected, one device that performs the main control function is called (4) another device that is connected to the function is called a USB device. In the first figure, the main $ move (7) is set as the USB host, and the media player (1) is set to be placed. Thus, the host device (7) includes a USB host, and the media player (1) includes ribs. A transmission medium for this purpose, in addition to USB, provides IEEE 1394 and a wireless LAN (Regional Network). In addition, the connection between them can be achieved by cables, ports or wireless media. When using IEEE 1394 or wireless LAN, a different concept from the concept of a host-to-device can be used. In the case of IEEE 1394, a peer-to-peer structure is used in which the host device (7) is set to the SBP2 initiator and the media player (1) is set according to SBP2 (serial bus protocol 2) as an upper layer protocol. SBP2 target. Therefore, modeling in which the host device (7) is set as the controller and the media player (1) is set as the target can be performed in a commonly used transmission medium including USB or IEEE 1394. With the popularity of various media players, consumers are increasingly looking to listen to songs stored in media players through the car audio system or the speaker system of the home audio device. To this end, an FM transmission function is added to a conventional media player to transmit songs played by the media player through a specific FM frequency. Further, the audio device outputs an audio signal by performing frequency modulation in the FM receiving mode. In addition, the Aux line in a conventional audio device extends separately and is connected to the headphone jack of the media player. Similarly, with the popularity of digital media technology, consumers are increasingly looking to play digital content stored in USB memory directly through the speaker system of a car audio device or home audio device. To this end, the present invention was filed on April 4, 2002 (Korean Patent Application No. 2003-21307) and published on October 15, 2003 (Korean Patent Registration No. 403,376) entitled "A MEDIAL PROCESSING DEVICE USING AN Patent application for EXTERNAL STORAGE DEVICE". According to the patent, the audio device includes a USB host interface to directly read and reproduce the content stored in the USB memory.

由於諸如Apple i-POD的一類媒體播放器組不包括FM 接收功能並且僅能通過專用介面來連接，因此，如果不另 行設.置汽車音頻的介面，則使用常規方案是有限制的。但 是消費者還是購買這種媒體播放器。此外，利用率不高。 近來，遇為 DRM(Digital Rights Management)非常重Since a type of media player set such as the Apple i-POD does not include the FM receiving function and can only be connected through a dedicated interface, there is a limit to the conventional scheme if the interface of the car audio is not otherwise provided. But consumers still buy this kind of media player. In addition, the utilization rate is not high. Recently, DRM (Digital Rights Management) is very heavy.
