This single player takes care of most of the legacy video needs in a school. Media formats come and go, but VHS and DVD are uncommonly persistent. Paired with an Addressable Classroom Module (ACM, MM-1210) and a MediaMaster server, these economical players let a school automate access to their existing library of video titles. We have selected this player for a few uncommon qualities. First, it operates as a unified player, abstracting away the distinction between DVD and VHS media. It is unfortunately rather common for players of this sort to behave like separate DVD and VHS players that happen to share a common chassis, making reliable automatic control difficult. Second, it does not go to sleep when left idle. The push toward lower energy consumption is a good thing in general, but in an automated control system, the players need to be ready to accept commands at any time. Third, the ACM can reliably learn and emit the necessary IR codes for this player. Because these qualities are far from universal, we must warn against substitution. You may call on ETR to qualify other players for use with the MediaMaster system, but we require a test unit and time to do the qualification. Where this is not practical, we recommend using the player(s) we have pre-qualified and given MediaMaster system part numbers.
