Introduction
Encoded Media’s IPTV Receiver 250 is an IP controllable set-top box.
The device also supports an optional RS-232C port capable of sending commands
and receiving status information.
The IP and serial control commands cover changing channel, simulating IR remote
control presses, modifications to the overlay interface, status request, and so on.
Status request response includes play state, the currently active stream URL,
channel name, hardware uptime, and more.
ABOUT ENCODED MEDIA

for delivering video across networks.

Overview
RECEIVER CONTROL
Example: where the Encoded Media IPTV Receiver is installed in a meeting room
along with other AV equipment.
The RS-232 port is connected to the room control such as a Crestron® or AMX®.
In this configuration, the Receiver can be sent commands such as “channel up”,
“play channel”, “volume down”, and so on. The Receiver can also be asked to return
its status, allowing the control system to check that it is behaving as intended.
SCREEN CONTROL
Example: where the IPTV Receiver is installed behind a standalone television screen.
The RS-232 port is connected directly to the screen via the RS-232 port on the LCD,
Plasma or Projector. In this configuration, the Receiver acts as an IP to RS-232
converter, allowing other authorised network devices to control and query the
screen via an IP port.

COMMAND SEQUENCE
Commands are executed in the order they are received. The host must wait for a
response from the Receiver before sending the next command.
Should the Receiver be sent a new command before completing execution of the
previous command, it may discard the previous command.
Should the host not receive a response from the Receiver within 2 seconds of the
command being issued, the host may consider the command or the response lost
during transmission, and should retransmit it.
