HD 101: Discrete IR codes
Anyone that has ever tried to use a programmable remote knows what is so great about discrete IR commands, but just by the name the concept seems foreign. It's pretty simple really, most remotes have one button for things like power and inputs, even though these buttons perform multiple tasks. So in the example of the power button, its function toggles between turning the thing on and off. The remote always sends the same code, but the device responds differently depending on its state. Put simple, when it is off, the IR code turns it on, and when it is on, the IR code turns it off. This is great most of the time because it cuts down on the number of buttons on the remote, while at the same time eliminates buttons that wouldn't do anything -- there's not much use for an on button when the unit is already on after all. Discrete IR codes are their mirror opposites.
