1 : Whether error-rate measurement is finished or not is judged, as shown in Table 3 below.
∗
2 : During DVD-VIDEO error-rate measurement, even after error-rate measurement is finished, playback continues, and the display of the
error rate results is retained. In this playback mode, if Error-Rate Measurement mode is exited by pressing the ESC key, then it is
reentered by pressing the ESC and SIDE-B keys (or ESC and PLAY keys), the error rate will not be updated, and the previous value is
displayed. To reset the previous error rate, stop disc playback.

3 : OK/NG judgment
In DVD/VIDEO and Video Mode recording, OK/NG judgment is displayed under the following conditions:
Table 3: On judgment whether error-rate measurement is finished or not
Table 4: List of OK/NG threshold values
Recording Mode
Judgment whether error-rate
measurement is finished or not
Recording/playback duration required
for error-rate measurement
Video mode
After playback of a certain amount (
∗
) of data
Measurement of the 16 ECC blocks is performed 16 times,
then the grand sum is used for calculation of the error rate.
The capacity is as follows:
16 ECC blocks
×
16 sectors

2048 bytes
×
16 times
= 8388608 bytes
= 67108864 bits
The time required for completion of error-rate
measurement varies, depending on the input video
signal to be recorded.
(The more the motion in the input video signal to be
recorded is animated, the shorter the playback time
required for completion of error-rate measurement
becomes.)
