Notice that after the LaserSearch command we have to then tell the LaserDisk to start playing, and

that we tell the Brick Brain to wait until it gets all of the echoed characters back from the LaserDisk player

so we know that the command has been accepted. After this we have a Ô00Õ to tell the Brick Brain that it

has found the end of the string.

A typical end string for a Panasonic LaserDisk show is:

Lead-in Pause Lead-out (ACK) (Lead-in) (Pause) (Lead-out) end-o-string

Translated into HEX ASCII, this string becomes (this is what you would enter):

02h 4Fh 50h 41h 03h 86h 82h CFh D0h C1h 83h 00h

and it would be displayed on the String Setup Menu as:

02 4F 50 41 03 (06) (02) (4F) (50) (41) (03) 00

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 Play command has

been replaced by a Pause command for the LaserDisk player.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 continue playing along until

the end of the disk is reached or another command is received.
