8-5 ERROR CORRECTION
8-6. AUDIO V. FADE FUNCTION
Major changes in waveforms during audio transitions may be heard as noise during playback.
To reduce this noise, an Audio V. Fade function is provided. When this is operating, audio transitions are detected
and the audio level is faded in a V shape during playback.
This function can be set with menu switch No. 214 <PBV. FADE>.
OFF (0):The V. fade function is disabled.
5M (1) :The V. fade function is enabled and audio transitions are faded out and faded in for 5 msec to reduce
noise. For best results, this position is recommended.
10M (2):The V. fade function is enabled and audio transitions are faded out and faded in for 10 msec to reduce
noise.
Error correction of digital playback signals is performed with the error correction
circuit and the error conceal circuit.
Error correction circuit : Errors in playback data caused by dropouts or mis-
tracking are corrected using the results of the data
operation.
Error conceal circuit : Major errors that the error correction circuit cannot
correct are concealed with the previous frame data.
Switching the setting of menu switch No. 112 <ECC MODE> turns the error
correction circuit ON/OFF.
The relationship between the menu setting and error correction operation is shown
in the table below.

NO CONCEAL o x
NO CORRECTION xx
o:Activated
x:Deactivated
• Normally set to “NORMAL (0)”.
• Turning part or all of the error correct circuit OFF allows you to compare noise
levels and check the head service life. For comparison, play back a moving
picture.
For example, when switching between “NORMAL” and “NO CONCEAL” shows a
big difference in picture quality, it indicates that the error conceal circuit works
and that a major error has occurred. In this case, the heads may no longer be
serviceable and should be replaced.
