1-1 Features

The HDW-D2000 is a high-definition (HD) digital videocassette recorder based on the HDCAM format. This unit uses large scale integrated circuits for signal processing, and has a simple internal construction, allowing it to provide functionality at least equivalent to a conventional VTR in a compact (4U size), lightweight, and low power consumption design.

In addition to HDCAM format recording and playback, the unit can also play back tapes recorded in the Digital Betacam and MPEG IMX formats.

HDCAM format

The HDCAM format uses the same 12.65-mm width tape as the conventional Betacam series. It provides high definition images, offering up to two hours of recording. For video signal compression, prefiltration and coefficient recording technologies are used.

High-performance heads and compatibility functions

The newly developed high-performance heads and dynamic tracking (DT) technology provide high- density recording and playback in narrow tracks with high reliability. The VTR automatically detects the recording format of tapes when they are loaded, so that no menu settings need to be made when changing formats.

High-precision digital signal processing and range of interfaces

The digital signal processing uses HD 4:2:2 component video signals complying with SMPTE 292M, which are converted into parallel data and then compressed into HDCAM format.

The audio signals are based on AES/EBU format, and are subjected to digital signal processing without being compressed.

The unit is equipped with a high definition to standard definition (HD to SD) downward converter, and has the following interfaces as standard equipment, for ease of connection to different external devices.

•SD analog composite signal output

•SD analog component signal output

•Analog audio signal input/output (4 channels)

•HDSDI SMPTE 292M input/output (HD digital video/audio, 4 channels)

•SDI SMPTE 259M output (component digital video/ audio, 4 channels)

•AES/EBU serial digital audio input/output (4 channels)

•SDTI SMPTE 305M input/output (HDCAM video/ audio data) (Option)

•Time code input/output

•CUE audio input/output

High quality four-channel audio

High quality 20 bit/48 kHz AES/EBU digital audio is supported. There are four digital audio input/output channels, and four analog audio input/output channels.

Multifunction control panel

While built in a compact 4U size, this unit has a front panel which provides a wide range of functions while maintaining existing operability.

Basic operation buttons and jog/shuttle dial

The basic buttons and jog/shuttle dial for VTR and editing operations are provided in the conventional VTR layout, ensuring continuity with conventional operating panels.
