This designates the sequence registration number and starts sequence switching.
Contents
Item Parameter Description
SQ Num 01 – 16 Sequence number
IMPORTANT
When a crosspoint switching command is sent for a destination channel where
sequence switching is already in progress, the sequence operation is stopped, and
the crosspoint switching command is executed.
When a sequence switching registration command (see 6.3.1) is sent for a destination
channel where sequence switching is already in progress, the sequence switching
operation is stopped.
If the correspondence between the logical channels and physical channels of the
destination and source are changed by the logical channel assignment function (See
section 6-9.) while sequence switching is already in progress, the modified results are
used in the sequence switching operation.
To perform sequence switching with a minimum of image distortion, the input video
must be synchronized with the external reference signal input to REF IN, and the
same DC level must be used.
Otherwise, image distortion may occur during switching, while switching may still be
possible.
