Remote Control
From DISE KnowledgeBase
Using Remote Control almost any software could control parts of playback, scheduling and several other things by sending messages over TCP, UDP or multicast UDP.

Command build up
If you are using Dise Parser, Dise Keyboard Control or any of our other applications that can send out Remote Control messages, then you do not really have to put any focus on how the messages should be formatted as these applications will do that for you.
On the other hand, if you want to create your own Remote Control messages to send on Multicast or UDP / TCP then you need to add an header to the message being sent out.
The header is separated in two sections, first a time stamp and then the Identity of the software sending out the message.
| Section | Description | Length |
|---|---|---|
| YYYYMMDDHHMMSS | Time stamp (year, month, day, hour, minute, second) | 14 characters |
| ID | Identity of the sending software. | Any |
The sections in the header are separated by a "|" (ASCII 124 decimal, 7C hex) character.
Example:
20090313184943|KeyboardControl|Play
Then the command and any parameters will be put after the header, all separated by the "|" character.

View incoming Remote Control messages
Dise Replay and Dise Probe both provide a Remote Control View which let you inspect the messages as they reach the player.
This is useful for troubleshooting and verification when creating an interactive presentation.
Scheduling
Scheduling can be controlled by using the Remote Control.
Synchronization
Dise NoBorders relies on synchronization of players. The synchronization signal is also transferred using the Remote Control.
Dynamic Data
It is possible to use data connections to text distributed through the remote control network.
This feature will give you the possibility to send out data from anywhere on your network (or Internets) and have Replay show the text directly when it is received. Update times vary depending on the display frequency, but should about 60 times a second. Since the update will be this quick this feature can be used for sport event timing and similar setups.
| Command | Parameter(s) | Description |
|---|---|---|
| DynamicData | This is a DynamicData message | |
| <Name> | The name of this dynamic data | |
| <Text> | The text to be assigned to the dynamic data name. |
Send dynamic data:
20090313184943|KeyboardControl|DynamicData|OurText|Dynamical text!
How to use
- Create a Text Object.
- Data Connect the Text Object and instead of giving a file name, enter: "#RC#OurText". (Change the "OurText" part to whatever you where calling the dynamic text in the input message).
- Setup "Enable Remote Control of this player" and "Enable Multicast communication" in the Replay Preferences > Communication tab.
- Start Replay with the Dise Movie containing the Text Object.
- Send multicast command as described above.
You can data connect to Dynamic Data on multiple locations. If you for some reason want to send data that contains multiple parts, you can send a string with a separator, for example, "1|200|FOO" and then use column processing in the Data Connection dialog to access specific parts.
Settings Changed Command
Dise Replay, Dise Probe, Dise Screen Control and Dise Computer Control support storing some settings in the Dise Complete database. It is then possible to send out a Settings Changed command to force the applications to connect and check if its settings in Dise Complete have been updated.
| Command | Parameter(s) | Description |
| SettingsChanged | This is a SettingsChanged message |
Send Settings changed message:
20090313184943|KeyboardControl|SettingsChanged
We recommend using the Dise Keyboard Control application to test commands and triggering.
