Abstract
A system for programming/controlling various audio/video devices coupled to one another via a bus structure, through the use of a single macro key utilizes an addressing structure. Each various audio/video device includes memory and a processor/controller for the memory and bus management. The memory is divided into master data memory and slave data memory depending on the role of the audio/video device. Data transfer over the bus only contains dummy numbers that are used as macro command addresses, with the macro data itself processed and stored in the various audio/video device. This eliminates the need to store the different commands of the various audio/video devices in the device chosen to initiate the macro. For each macro, one audio/video device is the master device while the remaining audio/video devices are slaves.
