These products achieve error correction performance for data read from the disc of double error correction in C1 and quadruple error
correction in C2 using the “refined super strategy”. This is the maximum possible performance for the CD format. As the error correction capability is increased, error correction efficiency becomes a major issue. However, these products provide processing capabilities adequate to surmount this issue. These circuits provide a C2 quadruple error correction capacity while achieving error correction efficiency equivalent to that of earlier double C1, double C2 error correction systems. At speeds from normal-playback speed to 24´ speed, these LSIs can logically correct up to 16 consecutive frames of missing data.

謝謝大大提供參考資料 ^_^
說明了C1C2運算效率對讀取的影響
這現象應該也能說明為何C1C2高的地方
Nero CD Speed的測試讀取速度會降下來 
之前我的討論忘了很清楚的問大大
『老音響的C1C2運算效率是否決不會影響jitter』
因為那時我腦海中想的是我家古老的CD音響讀爛片的景況
不過大大腦海中想的應該是後來的CD Player
所以我們看法有歧異
承蒙大大現在肯不吝提供這個解答
我想部分的歧異看法已趨於一致
謝謝大大的指教!
小弟還是請大大開討論串啦!
即使只有5頁，這也遠比20頁好
太多頁會讓人看不懂 |
