¶ How to designate an address for a search
There are the following four ways of designating an address for a search:
A
Address Block
When the BK command is issued, the address mode is set to block (During CD playback: absolute time [AMIN:ASEC:
AFRAME], during DVD playback: sector).
Example: During CD playback: For searching 2 min 3 sec 4 frame, designate BK20304SE
During DVD playback: For searching 250000 sector, designate BK250000SE.
As the sector for the innermost track of a DVD is 196608 (30000 h = 0 LBA), a number less than this cannot be
designated.
Address Track
When the TR command is issued, the address mode is set to track. This command is available only for a CD.
Example: For searching the 5th piece of music, designate TR5SE.
B Address Index
When the IX command is issued, the address mode is set to index (TNO:INDEX). This command is available only for a CD.
Example: For searching Index 3 of the 2nd piece of music, designate IX203SE.
Address Time
When the TM command is issued, the address mode is set to time (absolute time, AMIN:ASEC). This command is available
only for a CD.
Example: For searching 2 min 3 sec, designate TM203SE.
Once the address mode is set, it will be retained until it is changed the next time.
¶ How to calculate the error rate (Error count)
The error rate between the current point and the designated address is calculated.
C Example: To calculate the error rate between 20 min 0 sec 0 frame and 21 min 0 sec 0 frame and to display the result
during CD playback: BK200000SE210000EC?E
To calculate the error rate between 40000H and 41000H and to display the result during DVD playback:
262144SE266240EC?E (designated in decimal)

Multi Jump Fwd/Rev
The address is jumped by the designated number of tracks toward the innermost/outermost track of the disc (physical track,
