be sent out. Following this we tell the Br-SDC to wait until it gets first an ʻRʼ, and then a
<CR> back from the LaserDisk/DVD player.
A typical end string for a LaserDisk/DVD show is:
! ʻSʼ ʻTʼ <CR> (ʻRʼ) (<CR>) end-o-string
Translated into HEX ASCII, this string would be displayed on the String Setup Menu
as:
! 53h 54h 0Dh (52h) (0Dh)
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and the ʻPLʼ command has been replaced by a ʻSTʼ (still frame) command for the
LaserDisk/DVD 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/
DVD 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/DVD player at the end of a LaserDisk/
DVD show, then the player will continue playing along until the end of the disk is
reached or another command is received.
As an example of how you combine more than a single LaserDisk/DVD command in
the same string, we will now show a sample of a string which sends two commands at
the same time to the LaserDisk/DVD player.
A typical combined start string for a LaserDisk/DVD show is:
! LaserSearch ʻP ʻLʼ 1 ʻKʼ ʻPʼ <CR> (ʻRʼ) (<CR>) end-o-string
Translated into HEX ASCII, this string would be displayed on the String Setup Menu
as:
! serch 50h 4Ch 30h 4Bh 4Ch 0Dh (52h) (0Dh)
This string is just like the start string shown above, except that it sends a command
to disable the front panel keypad on the LaserDisk/DVD player after it sends the com-
mand to start the show playing, but before it sends the <carriage return> that tells the
LaserDisk/DVD player to start acting upon all the commands it has just received.
The following is a partial listing of the commands supported by Pioneer LaserDisk
and DVD players. It is by no means a complete list of all of the commands available to
you, but includes those common commands which you may actually need. Remember
that you only need to send the <carriage return> (0Dh) (shown as the last character of
all the commands) only if you arenʼt following the current command with any other
