4:2:2 Component Digital Processing
DIGITAL-S's outstanding picture quality is derived from 4:2:2, 8-bit component processing that assures the highest resolution and color detail even over multiple generations. Horizontal resolution for the system is 720 pixels or 540 TV lines. To maintain the best possible image quality in multi-generation editing and digital search, the compression ratio is set to a very mild 3.3 to 1 with DCT-based intra-frame coding and a data recording rate of 50 Mbps. The combination of these specifications with wide-band component recording enables DIGITAL-S to reproduce the finest color details and subtlest contrasts of an image while minimizing artifacts.
Video pre-read (BR-D85U only), never before available on a system in this price range, enables the recorder to first play back the digital signal on the tape, modify it with an external device, then re-record the modified signal in its place. It's a capability that allows an A/B roll system to be built with only two VTRs instead of three, saving the cost of one VTR. In addition, video pre-read allows complex layering effects to be performed even when working with a simple switcher with only one mix/effects bank. For multiformat editing, adding just one high quality DIGITAL-S recording deck with pre-read will provide virtually lossless editing, which means your finished tape will look like your original source footage. No other upgrade or addition to your current editing suite can provide such a dramatic increase in video picture quality.
High-resolution DIGITAL-S signals are captured and preserved on a high-density 1/2-inch tape featuring an advanced metal particle formulation based on W-VHS HDTV technology. Tape speed is 57.8 mm/s with a maximum recording time of 104 minutes. The cassette dimensions are the same as those of VHS. However, the cassette housing features a newly developed dust-proof cover and cannot be loaded into conventional VHS decks.
DIGITAL-S's audio specifications are just as impressive. Two independently editable, 16-bit PCM (pulse code modulation) signals can be recorded with a sampling frequency of 48 kHz, ensuring audio quality equal to today's most exacting standards. 2 linear cue tracks mirror the digital audio channels for effortless audio scrubbing and cueing.
The advanced capabilities of JVC's DIGITAL-S bring a new world of powerful editing features to your edit suite. Editing features include video pre-read (BR-D85U only), 2 independent time code reader/generators built in with VITC/LTC built-in time code recording. Independent editing of video, TC, or either channel of PCM audio is possible. A versatile range of search functions available via the jog/shuttle controls allow footage to be viewed in color at speeds of up to ± 32x Continuous, noiseless slow-motion playback is also available within a range of ± 1/3.
Thanks to the RS-232C interface, you can check the VTR's operating condition without interfering with operation. When the request command is sent via the 232C interface, diagnostic checks are run for head clogging, error rate, etc.
System phase, SC phase and video phase can be adjusted on the front panel while video level, chroma phase, chroma level and setup level can be adjusted remotely via the 15-pin D-SUB connector provided on the rear panel.
Slow-motion field or frame playback is menu-selectable.
To permit easy access to a full array of professional functions, DIGITAL-S VTRs incorporate an on-screen menu. Menu data is superimposed on the video monitor output. This menu system allows you to set 50 items while referring to the counter or on-screen display. Besides reducing the number of external switches, this system lessens the chance of function settings being accidentally switched on or off as is possible with external switches. A full set of LED indicators on the front panel assure you that the desired functions are engaged. On-screen mode check and warning indications are also provided. And, since the menu system is hierarchical, pressing one of the Direct Menu Access buttons allows you to go straight to the desired menu.
JVC's new DIGITAL-S recorders are designed for easy incorporation in any existing edit suite. Interfaces are provided for analog composite, Y/C, and component signals. Serial digital video interface (SMPTE259M and AES/EBU digital audio) is also available as an option.
To ensure DIGITAL-S/S-VHS mode compatibility, the drum structure features an upper stationary drum, a middle rotary drum and a lower stationary drum. (A conventional drum, on the other hand, consists of an upper rotary drum and a lower stationary drum.) Recording and playback heads on the middle drum make stable tape movement possible even at 4,500 rpm, while channel separation is improved by splitting the digital recording and playback rotary transformer between the upper and lower drums. The rotary drum itself is very narrow. This eliminates thicker air film at the drum inlet, ensures stable head-to-tape contact, and optimizes track linearity. The inner drum is tapered in order to reduce tape damage, powder drop, wear, and burn at the drum area. The material used to manufacture the drum has a higher silicone content than conventional aluminum alloy to improve wear resistance. The system uses a two-track, parallel recording system with two pairs of record heads located at 180 degrees to each other, and two pairs of playback heads located 90 degrees from the record heads. In addition, two erase heads are provided.
