Overview :



The Digital Video Machine is a studio quality MPEG-2 player with all the interfaces AV contractors need for professional installations. The Digital Video Machine stores its videos on Compact Flash cards, so playback is virtually instantaneous. You can copy clips to the media or transfer them using the Ethernet option.

It can be controlled either using the serial port or using Ethernet (Ethernet requires the DVM-7400/E model).
