Abstract

An audio data storage and playback apparatus is provided, including at least a USB hub or USB SIE, at least a storage media interface, and an audio codec. An upstream port of the USB hub or the USB SIE is connected to an electronic device with a USB interface. The storage media interface is connected to a downstream port of the USB hub or an endpoint of a USB SIE. The storage media interface can be connected to a portable storage media, such as flash memory, CD-R / W, DVD-R / W, and hard disk drive, to enable bi-directional data transmission and storage between the electronic device with a USB interface and the portable storage media connected to the storage media interface. The audio codec player forms a bi-directional data transmission connection with the storage media interface. The audio codec player is connected to at least an audio player and an audio input device. The audio data from the electronic device with a USB interface, the portable storage media connected to the storage media interface or the audio input device can be sent to the audio codec for encoding / decoding, and then stored or played back by the audio player or the electronic device with a USB interface to achieve the object of the present invention of multi-directional transmission, encoding / decoding, storage and playing back of audio data.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an apparatus for audio media storage and playback and, more particularly, to an apparatus for storing and playing digital / analog audio, and for encoding and decoding audio data for playback and multi-directional transmission and storage.[0003]2. The Related Arts[0004]Conventional portable multimedia storage and devices, such as flash memory, CD-R / W, DVD-R / W, hard disk drive, portable memory stick, digital camera, and so on, need to connect to a personal computer (PC) or a notebook computer for data conversion or multimedia playing, such as MP3, WMA, MIDI, WAV, and so on. The conventional audio data players are also limited to the playback of a medium. For functions, such as data conversion, decoding or storing, the players need to connect to a PC or a notebook computer to perform such tasks. This further limits the popularity of portable multimedia devices.[0005]Taiwan Patent Application...
