The ULTRA/MD-50 2/4-channel digital disk recorder is a new member of the ULTRA/BR familiy of digital video servers. With its simultaneous support for editable I-Frame only MPEG-2 and DVCPRO-25/50 compression formats, users can independently select for each 2- channel subsystem the compression standard which suits best their needs.

With 50-MBit compression ULTRA/MD-50 provides 180 minutes AV storage per channel in dual channel mode, or 90 minutes/channel in quad channel mode. Optionally 25-MBit DVCPRO or MPEG-2 formats may be selected to double the storage capacity.

ULTRA/MD-50 systems may be controlled via a traditional RS-422 interface like a digital VTR. Alternatively the system may be operated via its fast network interface (Ethernet, GigabitEthernet or Fibre Channel). In this mode, the two RS-422 ports are available to control a remote VTR, a digital crossbar or abother MD-50.

Unattended standalone operation with various power-on functions is also available. For each channel pair, ULTRA/MD-50 processes LTC Timecode, two video channels and four 48 kHz audio channels independently. In dual channel mode, DVCPRO and MPEG-2 clips with the same bitrate can be arbitrarily mixed during playout.

If required, active lines contained in the vertical blanking interval (like VITC) can be stored uncompressed on disk.

If the ULTRA/MD-50 system is used in a workstation environment, a virtual control panel, called videoWorkstation, may be exported to the host computers X11 display screen. This GUI manages all server setups, transport functions and image transfers interactively.
