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

Power requirements

The DVD-DSYN is powered from
the serial port RTS lines of the con­nected DVD players. The maximum
current draw is 6mA per-channel.

DVD-DSYN interface

The DVD-DSYN interface connec­tion is a standard DB9 male as
specified within the V300 player
specification.
Serial communication protocol is
9600 Baud, 1 Start bit, 8 Data bits, 1
Stop bits, No parity for all control
commands. All I/O is RS232 and
TTL compatible.

DVD control protocol

The DVD-DSYN communicates
with each player using the player
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

Installation

1. Power-up and insert the DVD media into each player and power-down again.

2. Connect each DVD-DSYNn port, starting with the ‘MASTER’, to a player SERIAL port.

3. Power-up each player (all within 30 seconds), or all together, and wait for the DVD-DSYN6 to STOP, PLAY and

PAUSE and then all players will be set-off together. At the end of the title the loop command authored onto the
media will restart chapter 1, pause and set-off all players together again.

Notes:

• One player must always be connected to the ‘Master port’. If a port on the DVD-DSYN6 is not required it can
be left unconnected. However, it should be noted that on power-up the DVD-DSYN6 will wait for the unconnected
port(s) to time-out for a period of one (1) minute before any PLAY instruction is issued.

• All connected players should be powered-up within a period of thirty (30) seconds
locked out. If a player becomes locked out the DVD-DSYN6 will not wait for this port to complete its title before
issuing a global play.

• The program DISC must be already inserted on power-up for the DVD-SYNn to take control.

• Always use good quality media to ensure good synchronisation. PLAY synchronisation accuracy is dependant on

individual players and may be ± 4 frames.
