Background

In this guide we built smarts into new MythTV menu items that replace 'task' buttons on smart remotes
This CommandIR application is by far the most popular trade-show demo I've had the privilege of showing.  The setup outlined here is pretty easy (albeit a bit tedious, see the note about LIRC Config at the end) and I thought that given the current economic situation it might be a good time to put out this article on "making your own" smart remote. 


Besides, it's a better solution than even the high-end remotes with CommandIR - controlling all devices in parallel from an on-screen menu - instead of holding up a remote, having line-of-sight to all devices, and waiting for it to finish controlling everything in serial sequence...


Though of course I recommend CommandIR for this application and the sample configuration is CommandIR specific, this guide can be easily applied to any LIRC compatible hardware. 


I assume some basic Linux/unix familiarity (editing files, setting permissions) and a basic LIRC setup. Have a quick look at our lircd.conf and .lircrc guides to get up to speed with LIRC then let's get started!

 

How it Works

  • Your PC receives remote-control commands
  • PC operates normally (commands are forwarded to software programs) until a 'task' is selected
  • In each 'task' mode, commands are translated and the corresponding device command is 'blasted' to the device from the PC
  • Task-switching scripts send the commands to that your TV to a specific input (eg. game device on Aux3) and how to bring focus back to your PC menu

User Interface

  • MythTV Menus
  • Any 1 remote
  • Absolutely no knowledge of how the system works or is setup

Sample Usage - What happens in the Background

  • Press "power" - all devices turn on; TV input gets reset to PC
  • Move MythTV menu cursor up/down to select a MythTV section, or a new 'Task'
  • Select 'Watch VHS Video' - TV switches to VCR input, sends 'play' to VCR, holds MythTV from responding keys
  • Press "pause" - we detect it and send the VCR's "pause" command to it
  • Press "stop" - we detect it again and send the VCR's "stop" command to it
  • Press "exit/back" - PC stops translating buttons to VCR and switches TV input back to PC, allows MythTV to respond to the remote again
