! serch 3Ah (0Ah)
Notice that after the LaserSearch command we have to then tell the LaserDisk to
start playing, and that we tell the Br-SDC to wait until it gets an ʻACKʼ (0Ah) back from
the LaserDisk player so we know that the command has been accepted.
A typical end string for a Sony LaserDisk show is:
! STILL <ACK> end-o-string
Translated into HEX ASCII, this string would be displayed on the String Setup Menu
as:
! 4Fh (0Ah)
The format of this string is pretty much like that of the startup string, except that there
is no need to send the LaserSearch string as was done at the beginning of the show,
and the ʻF-Playʼ command has been replaced by a ʻStillʼ command for the LaserDisk
player. This freezes the image to whatever the last image on the video disk was. Other
commands are available for blanking out the video, ejecting the disk, or a variety of
other things. You can even build up a string which will tell the LaserDisk player to search
for another frame on the disk and freeze or start playing from that frame. If no command
is given to the LaserDisk player at the end of a LaserDisk show, then the player will con-
tinue playing along until the end of the disk is reached or another command is received.
The following is a partial listing of the commands supported by Sony LaserDisk play-
ers. It is by no means a complete list of all of the commands available to you, but in-
cludes those common commands which you may actually need. Not all Sony players
support this full range of commands or respond in the same way to the commands sent
to them. These particular commands are from a LDP-1500ʼs manual, and so may not be
applicable to all Sony players. The values shown are what you would actually enter into
the strings.
