Audio/video system and function-extending module therefor

摘要

An audio/video (A/V) system and function-extending modules therefor are provided. The A/V system has a module rack, in which the function-extending modules are detachably inserted, and a base module. Each of the function-extending module sends and receives A/V data and stores control information for controlling itself. The base module receives the control information from the function-extending modules mounted in the module rack and displays the control information. If a user input according to the displayed control information is received, the base module sends the user input to a corresponding function-extending module and reproduces source A/V data provided by the function-extending module in response to the sent user input. By doing so, the A/V system in which a plurality of digital media is implemented is provided.
