Problems solved by technology

[0004] Known CD players with the function of converting files do not have the ability to compile ID3 tags, so the digital compressed files they make are only pure audio data without auxiliary data, and cannot bring into play the complete functions of digital compressed players. To add auxiliary data, it is still necessary to use a personal computer to search and download online, and then edit it with software, which is really inconvenient and difficult for ordinary users.

Abstract

The invention relates to a CD player which allows conversion into digital compression files and provides auxiliary information. The CD player has a function of converting uncompressed audio tracks stored in a CD disc into digitally compressed audio files, such as MP3 format. The CD player is provided with a network port which is used to be communicated to the internet. In the course of files conversion, the CD player searches and downloads information regarding an album or a song track through internet on-line data bases and converts the information into ID3 tag which is integrated into the digital compressed files and used for displaying associated information when the digital compressed files are played.

Description

technical field [0001] The invention relates to a CD player, in particular to a CD player capable of converting CD audio tracks into digital compressed files. Background technique [0002] For a long time, CD discs have always been the mainstream of commercial music media. However, with the maturity and standardization of digital audio-visual data compression technology, the MP3 format (format) derived from the MPEG-1 Layer 3 (Layer 3) standard has become more popular. The trend of replacing CDs, especially in portable and car music playback devices. The advantage of MP3 lies in its high compression rate (compression rate) and low distortion rate (distortion rate). A disc can store about 140 MP3 music files, and the sound quality loss of MP3 files is hard to detect by the human ear, so it is not easy to carry or replace a large number of CDs in portable and car music players. In the case of discs, MP3 does have its absolute advantages. Recently, other digital audio format...
