Features

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

74.25MHz 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 201/2q), 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.
