Description

The DVD-DSPRX interface con­nects to a Denon
controls the playback of the in­serted media.

The DVD-DSPRX emulates a

®

standard external serial control
device by issuing a PLAY com­mand whenever the motion of a
passer-by is detected.
Multiple PLAY commands are
inhibited with an in-built timer
that prevents the DVD-DSPRX
from issuing another PLAY within
a 10second time frame.
The Infrared sensor has an in-built
fesnel lens which gives the DVD­DSPRX a range of up to 5metres
in front of the device, preventing
unnecessary media playback.

V300 player and

Applications

The DVD-DSPRX is primarily
for use within a kiosk environ­ment where a DVD player sys­tem is used to provide POS and
EPOS advertising.

Power requirements

The DVD-DSPRX is powered from
the serial port RTS line of the con­nected DVD player. The maximum
current draw is 7mA.

Proximity sensing element

The DVD-DSPRX is fitted with an
Infrared sensing element. This ele­ment detects the change in Infrared
radiation a passing human body ex­hibits, triggering the DVD-DSPRX
internal circuitry to issue a PLAY
command to the connected DVD
player.
The sensing element has a useful
range of approx. 5 metres and
should be installed as per the dia­gram on the next page.

DVD-DSPRX interface

The DVD-DSPRX 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-DSPRX communicates
with the player using the player con­trol protocol **. This protocol takes
the form of ASCII command strings
of format:

[PC,RC,44]\r

\r – Carriage return

These strings allow the PLAY (Play)
command to be issued to the player
in response to the detection of a pas­ser-by.

DVD-DSPRX function

After the V300 player has been
switched on, the DVD-DSPRX
waits for 30 seconds before activat­ing itself ready for detection.
As soon as a passer-by moves within
range of the DVD-DSPRX the unit
immediately sends a PLAY instruc­tion to the player, it then disables
itself for 10 seconds to prevent mul­tiple PLAY instructions from being
sent.

DVD Media Authoring

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

a) The inserted disc must be in the

STOP condition for the DVD­DSPRX to start PLAY, therefore,
NO auto-start command must be
authored on the media.

b) THE DISC MUST BE LAID OUT

AS ONE TITLE CONTAINING
THE VIDEO PROGRAM WITH
NO RETURN TO BEGINNING
(LOOP COMMAND) AT THE
END.

PEDESTRIAN FLOW

1. Sighting of the DVD-DSPRX is critical if a reliable installation is to be provided. The unit should be fixed 45 - 90

degrees to the direction of pedestrian flow so that reliable detection is made.

2. Insert the flying lead into the RS232 IO connection on the Denon DN-V300 player.

3. Switch ON the player.

4. After 30 seconds, sensor stability time, the DVD-DSPRX will issue a PLAY instruction to the player whenever a

pedestrian is detected. A 10 second disable period is awaited after each PLAY instruction to prevent multiple trig­gering.

Notes:

• The PIR sensor should be pointed away from fluctuations in infra-red level e.g. drafts, curtains, windows, heaters,
fans etc.

• The detector has a range of approx. 5metres (16 feet) but placing the unit behind a piece of Perspex or glass to re­duce detection sensitivity can reduce this range. This is recommended when used in a kiosk environment.

• The sensor lens should never be touched, as this may leave a grease deposit that could cause poor operation.
