Roku PhotoBridge Programming: Patterns and Pitfallsfrequal.com

Basic ECP from the Command-Line

ECP is a single text-oriented protocol for sending short messages to PhotoBridge apps.

Telnet in to your PhotoBridge and try these simple examples:

Print the firmware version:

ecp system version

Report on whether the PhotoBridge is 'on'. Note that a PhotoBridge system never powers off or sleeps. However, turning it 'off' pauses any playing audio, shuts off video output, and turns off the front power LED.

ecp system power query

ECP commands can also perform actions. If a PhotoBridge is displaying corrupted or no output on a connected display, it is possible it simply is in the wrong mode. Use nmap or similar command to find its IP address, then telnet in and run a commend like this:

ecp system videomode component 1080i
The available outputs are
  • composite
  • svideo
  • component
  • rgb
And the resolutions:
  • 480i
  • 480p
  • 720p
  • 768p
  • 1080i
