STOP MARKER
Function:
Stop marker is set to the specified address.
Format:
Address
S M
Explanation: The specified address is written in the Mark Frame Register (or Mark
Chapter Register, in accordance with the addressing flag), the
completion status is returned immediately. When the stop marker
address is reached in
Play
or
Multi-Speed Mode
,
Still Mode
occurs and
the stop marker is cleared. The stop marker is also cleared when the
step command is issued to step through the address marker.
Here, the completion status is not returned when the address marker
is reached. Whether the stop marker address is reached or not can
be established by issuing the Frame or Chapter Number Request.
If a CLEAR or a REJECT command is sent before the marker is
reached, it is cleared.
NOTE:
A picture stop on a CAV disc takes
precedence over a SM PL command, however, the stop marker will
not be cleared when the player encounters the picture stop. When
another motion command, such as PL, is issued, the stop marker
that had been set, will be executed.
The stop marker is functionally similar to the auto stop operation of
the play and the multi-speed commands. The auto stop and the stop
marker return a completion status at different times. In an auto stop
operation, the completion status is returned when the marked
address is reached. In the stop marker operation, the completion
status is returned when the stop marker is set.
The stop marker command is used when status requests are sent to the
player before the address marker is reached; it is useful when the
operation mode is to be changed before the marked address is reached.
