The avclan protocol decoder handles decoding IEBus frames which are used in the multimedia control AVC-LAN protcol. It handles communications between Audio Head Units, CD Changers, Amplifiers, Switches, Navigation and so on.
Protocol
The decoder matches hardware addresses to their known device names as well as device functions (aka. Logical Addresses) to known names. It also decodes frame contents for some devices such as CD-Player, Radio Tuner, CD Changer and so on.
Usage with Pulseview
An example session with Pulseview can be shown below:
