Description

The DVD-DSYN6 accessory per­mits the PLAY
of 2-6* Denon
when using DVD media

All players are individually con­trolled and monitored by the
DVD-DSYN6, each player having
its operational status confirmed on
power-up allowing the automatic
selection of between 2 and 6 play­ers.

Once the DVD-DSYN6 has de­termined how many players are
connected a PLAY track 1 com­mand is issued followed by a
PAUSE command to each player.
The DVD-DSYN6 then waits for
all active players to become ready
and issues a global PLAY track 1.
Each player continues to play
the inserted media until the ‘re­turn-to-beginning’ loop pro­grammed at the end of the media

control protocol . This protocol
takes the form of ASCII command
strings of format:

[PC,PlayT,1]\r

DVD-DSYN function

Flowchart 1 shows how the DVD­DSYN functions on the Master
channel. The master channel will
wait for up to 60 seconds for the
connected slave players to be
switched ON, confirm that a DVD
disc is inserted and go into PAUSE.
Should a slave player fail to respond
within this period the player is
‘locked out’ by the master and will
not be queried when the global
PLAY needs to be issued.

The Master channel must ALWAYS
be connected to an active player.

Note: Accurate play synchronisation will not
be attained until the first loop has been com­pleted.

Synchronisation accuracy is dependant

on individual players and may be ± 4 frames.

DVD Media Authoring

When authoring DVD media for use
with the DVD-DSYN product range the
following requirements should be ad­hered to:

a) A short (10 frames max.) video black

period should be included at the begin­ning of the presentation to prevent still
frame images from being displayed
when the DVD-DSYN issues a
PAUSE.

b) The disc MUST be laid out as a single

Title with at least two chapters (Note:
Some authoring systems require these
two chapters to be authored within title
1 for correct function, incorrect func­tion being indicated by the DVD player
not displaying a PAUSE when the me­dia loops back to the beginning).

c) AN AUTOMATIC RETURN TO

START (TITLE 1 CHAPTER 1)

MUST

BE AUTHORED ON THE
MEDIA AT THE END OF THE
PRESENTATIONS FINAL CHAP­TER TO ALLOW THE DVD-DSYN
TO FUNCTION CORRECTLY.

d) All discs to be used in one DVD-

DSYN application should be authored
with approximately the same length of
content on each. This will prevent long
periods of video black being shown if
discs are of significantly different
length.

Repeat authored onto DVD media

These strings allow features such as
the On-Screen-Display (OSD) to be
controlled and media control com-
