Implementation of Distributed Multimedia Unit: CD Changer Equipped with MOST Networking Functionality

A network CD changer was implemented adopting MOST (Media Oriented Systems Transport) technology. It is controlled through network remotely and also conveys digital audio. The MOST CD changer is configured as a timing slave node. It has six CD slots and generates 16-bit resolution stereo audio at 44.1 ㎑ sampling frequency. Its response time regarding control message communication is within 30 ㎳ on average. Its functionality and dynamic behavior was investigated thoroughly. For that, a general and adaptable test environment was set up utilizing a commercial analysis tool. A few manual test programs were made and run in the environment.
