Workstation specifications
///FAST silver. comprises a PCI hardware codec, to which two external interface boxes are connected. These interface boxes - FAST Connect and FAST Component - are active processors which convert incoming video signals from CVBS, Y/C, YUV or SDI to the digital inpuit format, and the digital output format to the same choice of alternative formats. This configuration also accepts up to 4 analogue audio signals at different industry standard line levels or a stereo AES/EBU digital audio input. Audio output is either stereo anaolgue or digital AES/EBU. Silver. is a multiformat device, which is able to handle both NTSC and PAL in either 4:3 or 16:9 aspect ratio - the desired configuration is set via software to the hardware codecs on start-up.
During the actual editing process, only the digital equipment is necessary (the units marked in dark purple on the schematic below.) Audio equipment (green) and video monitoring (orange) is also used to monitor the editing process. VTR's and video processors (yellow or blue), are only employed during digitisation (play-in) and record to tape (play-out). This particular system offers play-in from and play-out to four different videotape formats, plus an assignable format for special requirements. A video colour processor may also be inserted into the play-in chain to enable colour processing immediately prior to digitisation.

All video and audio inputs may be patched manually via MUSA and BPO316 patchbays. Normal designation of video, audio and RS422 routing is controlled via a Sigma HPX 8x8 matrix which switched sources and destinations on 4-levels - Video CVBS, Video YUV, Audio 4 channels and RS422 VTR seriel remote control. There is a master routing control panel which handles all sources and destinations, and a local dedicated control panel on output 7 for technical monitoring. The routing switcher may also be controlled via RS232 seriel connection from the workstation.
EDIT2 ( equipment racks All equipment is housed in one of two assemblies - a 5 bay 19" rack unit housing VTR's processors, patchbays and computer mainframe and storage, and a control desk housing monitor displays, audio mixer, remote control panels. test equipment and input devices.

Under normal operation, all input and output signals for all equipment are available via physical patchbays, obviating the need for rear access for other than maintenance.

All audio lines are balanced 600 ohm, and all equipment is earthed via standrad EIA 3 pole power connections. Each rack bay, plus the control desk, peripheral computer equipment and room lighting is powered via a single phase 10 group distribution board with separate automatic cutouts for each supply group.

This system offers a high level of redundancy and flexibility - many traditional editing or dubbing operations may be handled in the analogue domain, and the editing workstation can also handle digital audio editing and processing outside the silver. environment with other media tools. EDIT 2 has tie-lines to adjacent edit suites and studio, as well as our VHS duplication facility, enabling VHS copying direct from the digital silver. environment.
EDIT2 is also equipped with two powerful workstations, one of which has an additional 240GB RAID storage, for graphics and audio editing applications. Remote control of primary VTR's is possible from both workstations for general scripting and logging operations. All workstations are interconnected via our internal network and have access over the network to the Internet via ISDN. When the majority of the quipment is powered down, the acoustics of the suite are perfect for voice and simple instrumental recording. EDIT2 also has direct access to adjacent studios and commentary booth.
