The ProDVD 175 professional DVD player can
also be controlled by an external controller or a
pointing device. This can be done via the I/O port
at the rear of the player. The connector type is
a D-sub 9 male. One and the same interface is
used for pointing devices as well as for external
control.

• The pointing device protocol has an automatic
pointing device protocol activated when the
transmission speed is 1200 baud.

• The control via an external controller is activated
when the transmission speed is 9600 baud.

Pinning input (sub-D9 male
on the player):

Pin signal I/O

1
2 RXD I
3 TXD O
4 +5V max 200mA
5 GND
6
7 RTS O
8 CTS I
9

I = input signal for the Player
O = output signal from the Player

RATINGS:

+5V output from the player:

− accuracy: +5V 10%

− supply current: min 200mA

RXD /TXD

− logical 1: -15V < signal level < +0.8V

− logical 0: +2.4V < signal level < +15V
(Output impedance pointing device max 4.7kOhm)

RTS /CTS

− Off (Negated): -15V < signal level <+0.8V

− On (Asserted): +2.4V < signal level <+15V

This interface allows for pointing devices and accessories
which are powered from the player using logic circuits
operating on 5V only.

Pointing device protocol

Communications signals follow the RS -232- C
specifications. For details of this see the EIA RS ­232- C standard.

− 1 start bit

− 7 data bits LSB first

− 2 stop bits

− Speed 1200 bauds
For pointing devices only two signal lines carry
data. The first is RTS, which is always output from
the player. The second is RXD, which is always
input to the player.

Device identification pointing devices

Every pointing device is to transmit its type
identification (ID) byte on request. This allows the
player to identify the device type that is connected
to it for maximum flexibility and ease of use.

Device ID sequence

• Negate RTS: Current data transmission to the
player is stopped.

• Assert RTS.

• The device sends its 1-byte device ID.

Note: It is adviseable to send a complete data packet
after the identification byte to establish the state of
the buttons.

Device ID timing

• A: device power-on to ID byte timing

− Min. 100ms

− Max. 500ms.

• B: negate RTS timing:

− Min. 10ms

− Max. irrelevant.

• C: Residual data transmission time when RTS is
negated:

− Min. 0 ms.

− Max. 1 byte period (1200 baud = 8.3ms)

• D: Assert RTS to ID byte timing when device is
powered:

− Max. 10ms.

External controller protocol

The communication with an external ProDVD
controller is done with the following settings:

− 8 data bits,

− 1 stop,

− no parity bit

− speed of 9600 Baud.

Communication between a ProDVD controller
and the DVD player consist of 3 different types of
information:

• External control commands

• External control status

• Asynchronous responses

The messages between the ProDVD and the
ProDVD controller look like: “[group, command,
parameterlist]\ r”
A group, command and parameter-list
betweensquare-brackets, followed by a carriage­return character (\r).
The group and command are not case sensitive;
there is no difference in the usage of uppercase
and lowercase characters. The parameter-list
exists of comma separated parameters, and are
case sensitive.

When the player receives a message from the
external controller, it will be acknowledged. This
acknowledgment will be done in 2 different ways.

• For external control commands, the acknowl­edgment will look like:

− group: group specified in the

received message (PC)

− command: command specified in the

received message

− parameter-list ReturnValue

ReturnValue can have one of the following values

− 0: No error

− x: Error code x

Example:

− player receives: [PC, RC, 66]\r

− player sends: [PC, RC, 0]\r

When the external controller receives the
response this implies that the player has verified
the received message (syntax), and the command
will be executed (It does not imply that the
command is executed without errors).

• For external control status messages there is
specified a response message on a request.

The response is the acknowledgment of the
request.

Example:

− Request: [PS, GetAudioStream]\r

− Response: [PS, GetAudioStream, 0, 2]\r

When the external controller receives the
response, the player has executed the command.

• When an external control command causes an
error, an asynchronous error message will be
send to the external controller.

Example:

− Player receives: [PC, RC, 44]\r

− Player sends: [PC, RC, 0]\r

− Player sends: [PR, Error, 10]\r

When the external controller receives the
response, the player has verified the message
(syntax), and when no errors occurred, the
command will be executed.
If an internal error occurs and the command can
not be executed, an error message will be send.

• When the command does not cause an error,
but execution of this command changes the
state of the player, this status change will be
send to the external controller. Also other
asynchronous responses, e.g. start of chapter,
can be expected.

Example:

− Player receives: [PC, RC, 44]\r

− Player sends: [PC, RC, 0]\r

− Player sends: [PR, StatusChange, 4]\r

− Player sends: [PR, SOC, 2]\r

RELATIVE COORDINATE
AND MANEUVERING
DEVICES

Relative Coordinate devices e.g. Mice, Trackballs
and Maneuvering devices e.g. Joysticks and joypads

Data Flow

During normal operation (RTS asserted):

• Data is sent to the player via RXD.

• Every time the device is moved or button state
is changed, 3-byte data packets should be trans­mitted to the player.

• No data should be transmitted when the device
is stationary (in center position) and the button
state is unchanged (pressed or released).

• A button state change or device position change
should not interrupt a data packet transmis­sion.

• To allow for additional buttons on the pointing
device, one additional byte (with d6 =0) may be
added to the data package. Systems specified to
work with the specific device will react to this
byte; other systems will ignore it.

bt 1 = button 1: 1 = pressed
0 = not pressed
bt 2 = button 2: 1 = pressed
0 = not pressed
X7..XO: 8-bit data horizontal

movement. 2’s complement.
left direction = negative
($FF..$80)
right direction = positive
($01 ..$7F)

Y7..YO: 8-bit data vertical

movement.

2’s complement. up direction = negative ($FF..
$80) down direction = positive ($01..S7F) A
value of $00 for horizontal or vertical movement
indicates no movement in that direction.

note: bt1 and bt2 will be implemented as OK button

ABSOLUTE SCREEN
DEVICES AND ABSOLUTE
COORDINATE DEVICES

Absolute screen devices and absolute coordinate
devices e.g. Touch Screens, Light Pens.

Data flow

During normal operation (RTS asserted):

• Data is sent to the player via RXD.

• Every time the pointing indicator is in motion in
the active area or a button state is changed, 4­byte data packets should be transmitted to the
player.

• No data should be transmitted when the
pointing indicator is not in the active area and
the button state is unchanged (pressed or
released).

• A button state change or device position change
should not interrupt a data packet transmis­sion.

• To allow for additional buttons on the pointing
device, one additional byte (with d6 =0) may be
added to the data package. Systems specified to
work with the specific device will react to this
byte; other systems will ignore it.

command: SetPlayMode
parameter list: PlayMode,

12

ProDVD 175

ProDVD 175

For more information about the ProDVD 175, please contact the website: www.prodvd.philips.com

PlayMode is one of the following strings:

“CHAPTER”:
The disc will stop when a chapter is played.
“TITLE”:
The disc will stop when the last chapter of a title
are played.
“DISC”:
The disc will start the next title when a title is
played and stop after the last titles of the disc are
played.
“OFF”
SetPlayMode is inactive.

Example: [PC, SetPlayMode,

CHAPTER]\r
The play mode is set to chapter play.

Note 1: The parameter list is case sensitive, thus the
PlayMode must be in uppercase.

Note 2: The behaviour of this feature can be influ­enced by and combined with user settings like for
instance “repeat disc” and “repeat chapter” given by
the user trough the remote control or the RS-232.

Note 3: The play mode status will be set to the stand­ard setting after switching on the power of the player.
(not stored in NVRAM)

Note 4: The default playmode is disc.

Time Search

Group: PC
Command: Time
Parameter list: Time Search

A typical EC command line for time search input
may look like this:
Example: [PC, Time, 1,35,15]

The player is supposed to start playing at 1:35:15

Further, Time Search (though EC) behavior would
be same as handled through RC, i. e. whenever

time search icon is required to be disabled on the
menubar, time search request through EC would
be ignored and it would result in an error message
to EC.

Note 1: In following circumstances time search icon is
disabled on the menubar (SW3.xx.xx behavior):

• Presence of any child menu (like FTS menu, user
preference menu, etc.) of the menubar on the
screen

• Active special modes like FTS ON, PBC ON for PSD
discs, etc.

Note 2: if the time search window is present on the
menu bar, time search request through EC would be
ignored

Note 3: If the time search request can be handled
through the menubar via RC, then time search request
through EC would require a start of play as in time
search through RC.

Note 4: On entry of any time value through EC com­mand line, that’s syntactically correct (in terms of
commas, etc.), if the time value entered in the com ­mand line is not meaningful (for eg. time value hap­pens to be greater than the duration of the disc), the
request also would be ignored and it would result in an
error message. However, the user would not be imme­diately prohibited from entering the time (as on the
screen) in the command line that can’t be played.

In all cases, where EC gets an error message, the
type of error message would be in line with other
error messages that EC gets on erroneous inputs.

NAVIGATION AND
HANDLING NON
VOLATILE MEMORY

The ProDVD 175 professional DVD-Video player
is equipped with NVRAM (Non Volatile Random
Access Memory) for saving application data. The
data written to the NVRAM will be available
every time the application is played or can be
used to transfer data from one disc-application to
another disc- application.

The DVD application will be able to set, update
and react on the contents of this non-volatile
data. This data can be retrieved through the
players’ RS232 interface for data processing or
statistical analysis.

A few examples of what you can do with NVRAM
are:

• Playlist: Create your own selection of video
sequences and automatically play this selection
every time you power on the player.

• Let the user take a test and save the results of
the test for later (protected) reviews by the
manager.

•

Allow certain ProDVD 175 players to play spe ­cific video fragments while other ProDVD 175
players will not play these video fragments, using
the same disc.

• Store visitors’ statistics: how many times have
people made specific selections at the kiosk?

NVRAM manual

More information about what you can do with the
NVRAM functionality and how it can be used can
be found in the special NVRAM manual.
