同时,解码电路对音频信号处理的功能也更强大了,如第一、第二代的DVD解码芯片,其音频解码器一般只有MPEG-2音频解码或杜比AC-3的5.1声道解码功能,而第三代的DVD芯片一般还具有DTS数字声音信号输出,以及DTS的5.1声道数字环绕声解码功能;有些DVD解码芯片还具有对高解析度HD CD格
At the same time, decoding circuit for audio signal processing function is also more powerful, such as the first and second generation DVD decoder chip, the audio decoder generally only MPEG-2 audio decoding or Dolby AC-3 5.1 channel decoding , While the third generation of DVD chips generally also have DTS digital audio signal output, and DTS 5.1 channel digital surround sound decoding; some DVD decoder chip also has a high-resolution HD CD grid
