Here's a little something about the JVC D-VHS not sure what it all means but maybe somebody can make heads and tales of it:
1) With recordable DVD (and surely recordable HD DVD) right around the corner, why would the consumer want a new tape â€“based system?
Recordable DVD can not record HD digital signal. D-VHS is the only media that can record and playback HD sources right now. D-VHS tape has 50GB of capacity which is approx. 10 times larger capacity than current DVD capacity. Considering SD recording, D-VHS STD mode has 14.1Mbps data transfer rate, on the contrary, DVD has up to 10Mbps. That results D-VHSâ€™ better picture quality than DVDâ€™s. If HD DVD came up, price will be far high and recording time will be shorter than D-VHS VCRs. The price of recording media (disk) will be much higher that D-VHS tape.
2) What formats will play in this machine?
D-VHS HS, STD, LS3 mode / S-VHS/ S-VHSET/ VHS
3) What is the difference between DTCP and HDCP?
DTCP is a copy protection system for compressed MPEG2 video data. This is a secure system for iLINK (IEEE1394) connection. On the contrary, HDCP is copy protection system for baseband digital HD signal. It is announced that HDCP will be incorporated in Digital set top box and HDTV.
4) Will this deck include DVI/ HDCP outputs?
5) If I purchase two of these machines can I copy tapes?
If contents has copy-free CGMS bit, you can copy tapes.
6) What tapes do I need to record a HD program?
A D-VHS tape is needed.
7) Are these tapes readily available and at what cost??
(Please ask tape sales staff @JCA)
8) What video formats will this deck support?
NTSC, 18 ATSC formats.
9) Are there any other manufacturers supporting this format?
Sony,Mitsubishi, Panasonic, Hitachi, Philips,
10) What audio systems does this deck support?
5.1ch Dolby Digital optical output
VHS normal audio
11) How will this deck work with dbs and systems such as Direct TV and Dish Network?
If Digital STB have iLink (IEEE1394) digital output terminal, digital broadcasting signal can be recorded â€œas isâ€ by DH30000 via iLink connection.
12) Will this work with my current TV?
DH30000 has playback format converter that can convert HD signal to 480i NTSC signal.
13) Will there be any benefits for me if I presently do not receive a HD signal?
1. With built-in MPEG2 encoder, you can record from analog signal with MPEG2 digital conversion.
2. You can dub from DV camcorder with DV-MPEG2 convert.
3. Using LS3 mode, you can record up to 24hrs with single cassette.
4. If you record analog sources by HS mode, it will be the best quality recording ever.
14) Will all previous HD ready televisions work with this deck? Are adapters needed?
DH30000 has component video output (Y, Pb, Pr)
15) What type of tuner will be needed?
If you want to record digital broadcast, you need digital STB with IEEE1394 compliant digital output.
16) How does this deck compare to the other D-VHS formats on the market or soon to be released?
Only DH30000 has HDTV HD MPEG2 decoder. Connection to HDTV is simple and easy as VHS VCRs.
DH30000 has CODEC function.
DH30000 has LS3 mode.
DH30000 has DV input terminal.
17) What is the difference between D-VHS recorder and DVD recorders
HDTV digital recording is possible by D-VHS VCR.
Media Capacity: D-VHS 50GB/cassette
Media Cost : D-VHS tape is much cheaper than DVD-R disc.
Recording bit rate: 28Mbps (D-VHS HS mode), 14Mbps (D-VHS STD mode), around 4Mbps(DVD)
18) When is there going to be prerecorded software available?
Nothing is fixed regarding prerecorded software. We hope in near future HD prerecorded software available.
19) Can I hook this deck up to a computer?
20) What is the final jack pack configuration?
Y, Pb, Pr Component/ S-Video/ Composite Video
21) Will this deck support MPEG1 video?
No, it doesnâ€™t.
22) Will this deck have IEEE1394 for digital dubbing, editing from MiniDV?
Yes, DH30000 has DV input terminal. DV signal is uncompressed and converted to MPEG2 signal for D-VHS recording.
23) Is this deck backwards compatible with the other VHS formats?
S-VHS, S-VHS ET, VHS compatible.
24) Can this deck also be used as an editing deck with flying erase head?
No. DH30000 does not have FE head.
25) How loud is the fan?
No problem with daily use.
26) Can this VCR be used non-linear editing solutions via firewire? Are there any limitations?
This model doesnâ€™t have NLE capability via firewire. Thereâ€™s no way to import data to PCs.
27) If I own a progressive Mini DV camcorder, can I get directly via firewire, and if yes, what are my benefits?
No matter which DV camcorder you have progressive or interlace, video output format is NTSC (480i). (Please do not mix up progressive video and progressive scan CCD.)
DH30000 has DV input terminal for MPEG2 conversion recording of DV footage. You can archive your footages to large capacity D-VHS tape w/o picture quality degradation.
28) Will I be able to record a HD program from Echostar, Direct TV and HD Cable boxes (AOL-Time Warner, Comcast and Cablevision)
If STB have digital DTCP output, you can record HD programs as far as program recording is permitted by copy protection system(CGMS).
29) Our GC-QX5HD camera has HD output. There are other manufacturers planning this feature also, can I record these images from the digital still camera to tape keeping these images in 1080i?
No. DH30000 can record HD pictures from iLINK terminal only.
30) Do we have any other CE manufacturers interested in this new format? If yes, are we actively discussing others to produce units utilizing this D-VHS format?
Yes, to expand D-VHS format, we should actively discussing many CE manufacturers.
