Quite simply I would like to have a board, if one exists, that i can plug my TV stream (the cord that comes from my cable box) into the Pi and have an HDMI come out of the pi to the TV. Using python the Pi itself could switch between the TV and the Pi.

  • A remote controlled HDMI switch is probably easier. You plug the Pi and your cable box into it and connect the switch to the TV. I use this one amazon.com/IOGEAR-3-Port-Switch-Remote-GHDSW3/dp/B004JN55JU/…. Commented Jul 2, 2015 at 22:15
  • I'd prefer it be directly controllable via the Pi. Is that possible?

  • Use the GPIO pins to operate an IR LED or modify the remote to be switched via the GPIO pins. Commented Jul 2, 2015 at 22:23
  • I'm not sure I could do that with my current knowledge...

You have 3 options to connect to tv and send command to it

  • rs232 serial port
  • Lan
  • Hdmi cec

You need to check your tv and found out which one is supported .


Ern, sorry if I'm being too harsh. Just exactly when did HDMI-CEC commands went vintage? https://en.wikipedia.org/wiki/Consumer_Electronics_Control

You can send a "switch input to HDMI" signal to most modern TVs. In fact, some Raspberry Pi mediacenter distros like XBian does it out of the box. Worth a try, looks exactly like what you need.
