Embodiment Construction

[0051] figure 2 It is a system architecture diagram of the digital music conversion device of the present invention, which mainly includes three components, which are respectively a digital music player 10, a digital music conversion device 20, and a portable recording medium 30, which are connected to each other through the first data transmission interface 40 and 41 and the data transmission line to connect and transmit data.

[0052] Digital music player 10 is used to play a recording medium carrying digital music files. The file format of digital music files is defined as the first format here, such as CF memory card or music CD, etc. If it is a music CD, the digital music on it If the file format is CDI format, then the digital music playing device 10 can be a walkman, stereo, VCD player or other playing devices capable of playing music CDs.

[0053] Digital music conversion device 20 is connected with digital music playback device 10 by first data transmission interfac...

Abstract

The digital music converter is used to convert the digital music file in the first format into the digital music file in the second format. It consists of the first data transmission interface connected via one corresponding data transmission line to one digital music player, which sets the record medium carrying the music file in the first format selectively; one format converting treatment module connected to the first data transmission interface for receiving the music file in the first format, analyzing, decoding and converting into the music file in the second format with relatively less storing space; and one second data transmission interface connected with the format converting treatment module and connected selectively to one portable record medium capable of communicating with the second data transmission interface for storing the music file in the second format in the portable record medium.

Description

technical field [0001] The invention relates to a digital format file conversion device, in particular to a digital music conversion device applied in a music CD player. Background technique [0002] In recent years, with the popularity of the Internet, the storage and transmission of high-quality audio data has become more and more important. In order to reduce the time, cost and network bandwidth of storage and transmission, audio signal compression technology standards have been established internationally. , namely ISO MPEG 1 PART 3 (ISO / IEC 11172-3). This standard defines three levels of encoding methods, and the third layer (MPEG 1 Audio Layer 3) encoding method can compress mono or stereo (stereo) signals up to a compression ratio of 12:1, still Sound quality like an audio CD can be maintained. [0003] The MP3 (MPEG Audio Layer 3) format music file standard is an audio signal compression method with only a small loss of sound quality, so it is widely used by the pu...
