- I attended a session on DCC and MD at the recent AES conference in San
- Francisco.
-
- Sony said that the MD decoding algorithm is fixed, but the encoding algorithm
- can be changed as improvements are made. They also said that the algorithm
- is currently the same for the professional and home units, but it may not
- remain that way. It wouldn't surprise me to see "improved" recorders hitting
- the market in a few years.
-
- DCC, on the other hand, uses a fixed encoding algorithm but allows the
- decoder to be changed. Hence, we might see "improved" players but not
- recorders. I assume this means that the professional and consumer recording
- algorithms will always be the same.
