3 是指 Μ P E G ( Μ 〇 t i ο η P i c t u r e E X p e r t G r 〇 u p )第 三代,是MPEG技術中之音頻部份之技術之一。MP3利用 音頻資料编碼技術,以使現存之資料之音質不會降低之 方式進行壓縮,用來製成音頻檔案格式。此種MP3檔案 通常具有AAU (以下稱為”音頻解碼單位”)之記錄格式。 亦即,由標頭(header),錯誤核對碼(CRC),音頻資料 (audio data),和補肋資料(auxiliary data)構成 β 因 此,用以再生MP3檔案之MP3放音機通常使用音頻專用機 器用來傳送被壓縮之音頻檔案藉以使其再生成為音頻資 訊。 另外一方面,習知之MP3放音機裝箸有液晶畫面,可 以與音頻資訊分開的顯示簡單之文字資訊(如同歌曲之 歌名等之單純之參考内容),但是該文字資訊不能使文 字與音頻資訊對應,亦即不能使字幕資訊同步化的進行 顯示為其問題。 另外,在利用卡帶之習知技術之字幕帶方式中,所使 用之方法是在音頻專用帶之2餡磁執分別收納上述之字 -3- 本紙張尺度適用中國國家標準(CNS)A4規格(210 X 297公釐) — — — — — — — — — — — (請先閱讀背面之注意事項再填寫本頁)

Device. [Explanation of related technologies] Generally, MP 3 refers to MP E G (M ot π π π ct e r E X p er t G r 〇 u p) the third generation, which is one of the audio part technologies in MPEG technology. MP3 uses audio data encoding technology to compress the existing data in such a way that the sound quality will not be degraded, and is used to create an audio file format. Such MP3 files usually have a recording format of AAU (hereinafter referred to as "audio decoding unit"). That is, the header, error check code (CRC), audio data, and auxiliary data constitute β. Therefore, MP3 players used to reproduce MP3 files usually use audio only. The machine is used to transmit compressed audio files for reproduction into audio information. On the other hand, the known MP3 player is equipped with a liquid crystal screen, which can display simple text information (such as simple reference content such as song title) separately from audio information, but the text information cannot make text and audio Information mapping, that is, the inability to display subtitle information synchronously is a problem. In addition, in the subtitle tape method using the conventional technology of cassettes, the method used is to store the above-mentioned characters in the two magnetic pads of the audio-only tape. -3- This paper standard applies to the Chinese National Standard (CNS) A4 specification ( 210 X 297 mm) — — — — — — — — — — — (Please read the notes on the back before filling out this page) Printed by the Intellectual Property Bureau Employee Consumption Cooperative of the Ministry of Economy 462040 A7 B7 Employee Consumption of the Intellectual Property Bureau of the Ministry of Economic Affairs Cooperative printed 5.
