4. Remote controller tables

Unfortunately, for several years, there was no effort to create uniform IR keycodes for different devices. This caused the same IR keyname to be mapped completely differently on different IR devices. This resulted that the same IR keyname to be mapped completely different on different IR’s. Due to that, V4L2 API now specifies a standard for mapping Media keys on IR.

This standard should be used by both V4L/DVB drivers and userspace applications

The modules register the remote as keyboard within the linux input layer. This means that the IR key strokes will look like normal keyboard key strokes (if CONFIG_INPUT_KEYBOARD is enabled). Using the event devices (CONFIG_INPUT_EVDEV) it is possible for applications to access the remote via /dev/input/event devices.

It should be noted that, sometimes, there some fundamental missing keys at some cheaper IR’s. Due to that, it is recommended to:

Notes

On simpler IR’s, without separate channel keys, you need to map UP as KEY_CHANNELUP

On simpler IR’s, without separate channel keys, you need to map DOWN as KEY_CHANNELDOWN

On simpler IR’s, without separate volume keys, you need to map LEFT as KEY_VOLUMEDOWN

On simpler IR’s, without separate volume keys, you need to map RIGHT as KEY_VOLUMEUP
