Interlace/Progressive Switchable
Recording and Playback
An important element that makes the HDW-D1800 and
HDW-1800 recorders so versatile is their ability to record
and play back material recorded in multiple signal formats.
They support both interlace and progressive recording modes
with the following selectable frame rates: 1080/59.94i,
1080/50i, 1080/29.97PsF, 1080/25PsF, 1080/24PsF, and
1080/23.98PsF.
High-Definition Picture Quality with
the HDCAM Format
The HDW-D1800 and HDW-1800 recorders adopt the
proven HDCAM format to record 1920 x 1080 resolution,
high-definition component digital signals. The HDCAM
format uses an extremely intelligent compression scheme
with a high video bit rate of 140 Mb/s (data rate on tape of
185 Mb/s.) This allows the format to provide superb picture
quality onto a highly robust and cost-effective 1/2-inch tape,
with a design inherited from the Betacam series.
Powerful Legacy Playback Capability
(HDW-D1800 only)
The HDW-D1800 recorder offers a powerful legacy playback
capability for Digital Betacam and MPEG IMX format tapes.
This allows flexible use of acquisition tools in the field, and
easy integration into existing editing environments.

also output 1080i signals in HD-SDI from SD legacy playback.
