This HD VTR is a hi-vision digital VTR for recording and playing back the video and audio signals complying
with BTAS-001A (1125/60 high-definition TV system studio standard) and SMPTE 274M standards.
By image-compressing the hi-vision signals and digitally recording them, this unit delivers up to 124 minutes
of recording and playback using a
1
/2q cassette (the maximum length with the 1080/23.98p format is
155 minutes.). It is possible to switch between the following system formats to record and play back the sig-
nals in one of these formats: 1080/23.98p (8-channel audio), 1080/24p (8-channel audio), 1080/25p
(8-channel audio), 1080/59.94i (4-channel audio version), 1080/59.94i (8-channel audio version), 1080/50i
(8-channel audio), 720/59.94p (4-channel audio version), 720/59.94p (8-channel audio version), 576/50i
(8-channel audio), 480/59.94i (4-channel audio version) and 480/59.94i (8-channel audio version).
Only playback is possible with 576/50i (4 audio channels) format tapes which have been recorded using the
VTR (AJ-D580).
Simultaneous output of HD (hi-vision signals) and SD (standard signals) can be achieved.
In the case of the 1080/23.98p, 1080/24p and 1080/25p formats, the 1080/23.98psf, 1080/24psf and
1080/25psf (Progressive Segmented Frame) formats which divide the frames into two segments every
1/47.96, 1/48 and 1/50 of a second, respectively, for interfacing are also used.
Picture/sound quality at a reasonable price
≥High picture quality digital recording of signals complying with studio standard
The hi-vision studio standard signals, which have been 10-bit quantized using sampling frequencies of
74.25 MHz for Y signals and 37.125 MHz for the PB and PR signals, are image-compressed and digitally
recorded to meet the full range of specifications under the hi-vision studio standard.
Virtually distortion-free recording and playback at a low compression rate–and with a signal-to-noise ratio of
60 dB and a wide band (Y: 30 MHz, PB/PR: 15 MHz), which have to date proved difficult to achieve with
analog VTRs using 1/2-inch tapes–are now made possible by utilizing a high recording rate of around
300 Mbps: the result is a consistently high picture quality all the way through from the initial recording to
editing.
≥Compact size, light weight and low power consumption
The unit is compact (height equivalent to 5U, depth at 20
1
/
2
q), lightweight (69.96 lbs), low in power consump-
tion (260 W) and easy to handle.
≥High cost performance
In addition to featuring the basic functions and performance of HDD5, this HDVTR makes it possible to switch
between the 1080/23.98p (8-channel audio), 1080/24p (8-channel audio), 1080/25p (8-channel audio),
1080/59.94i (4-channel audio version), 1080/59.94i (8-channel audio version), 1080/50i (8-channel audio),
720/59.94p (4-channel audio version), 720/59.94p (8-channel audio version), 576/50i (8-channel audio),
480/59.94i (4-channel audio version) and 480/59.94i (8-channel audio version) system formats to record and
play back the signals in one of these formats. Furthermore, installation of a format converter board enables
HS and SD signals to be output simultaneously.
≥Digital audio with high sound quality
A high sound quality with a dynamic range of 100 dB is delivered by 20 (24)-bit 48 kHz sampling. Not only
can recording, playback and editing be conducted separately for each of the 4 (8) channels but channel mix-
ing is also possible. Moreover, one channel is provided for the analog (cue) track. (At 1080/23.98p,
1080/24p, 1080/25p, 1080/50i and 576/50i formats, 8-channel audio and 24 bit format.)
With the 1080/59.94i, 480/59.94i, or 720/59.94p system format, either the 4-channel 20-bit format or the 8-
channel 24-bit format can be selected. However, due caution should be exercised in operation since the
recording format used for the 8-channel audio version and the one used for the 4-channel audio version dif-
fer, and these differences pertain to their video recording areas as well. As such, these two system formats
are not mutually compatible.
≥Compact
1
/2z tape cassette
Two sizes of cassette, [L: 124 minutes (1080/59.94i, 720/59.94p and 480i), 149 minutes (1080/50i,
1080/25p), 155 minutes (1080/23.98p and 1080/24p), 112 minutes (576/50i) and M: 63 minutes
(1080/59.94i, 720/59.94p and 480/59.94i), can be used with this unit: this enables the size best suited to the
intended application to be selected. The compact
1
/2q cassette takes up minimal storage space and offers ex-
cellent handling ease.
