D- VHS
VHS
is a digital video recording format developed by JVC, in collaboration with Hitachi, Matsushita, and Philips. The "D" in D-VHS originally stood for "Data", but JVC
JVC
renamed the format as "Digital VHS". It uses the same physical cassette format and recording mechanism as S-VHS
S-VHS
(but needs higher-quality and more expensive tapes), and is capable of recording and displaying both standard-definition and high-definition content. The content data format is in MPEG transport stream, the same data format used for most digital television applications. The format was introduced in 1998. As a final effort for VHS, the D- VHS
VHS
system had significant advantages as a highly versatile domestic recorder (the other tape-based formats are DV and Digital8, which never gained any traction except as camcorder media), but given the wholesale move to DVD
DVD
and then hard disk drive (HDD) recording, the format has failed to make any headway into the video market. There has been no small-format version of D- VHS
VHS
equivalent to VHS-C; JVC, the originator of the format, chose to use MiniDV
MiniDV
for its digital camcorder lines, and since 2005 has also expanded into tapeless camcorder designs based on hard drive storage (the Everio line). JVC does market the Digital-S
Digital-S
format for professional use; while the tapes and technology used are superficially similar to D- VHS
VHS
tapes, the underlying data format is based on the DV codec and the media formulation is drastically different.

Tape length and speeds[edit] D- VHS
VHS
VCRs come with multiple speeds. "HS" is "High Speed", "STD" is "Standard" and "LS" is "Low Speed"; where LS3 and LS5 represent 3 and 5 times the standard length of tape. High-definition content such as 1920x1080 or 1280x720 is typically stored at 28.2 Mbit/s (HS speed). Standard-definition content such as 720x576 (720x480) can be stored at bit rates from 14.1 Mbit/s down to 2.8 Mbit/s (STD, LS3, LS5 speeds). The quality of STD speed is actually superior to the average DVD, since this speed has a much higher bitrate (approximately 14 versus 5 Mbit/s average) and suffers few compression artifacts. The LS3 speed is roughly equal to an amateur DVD
DVD
with some visible artifacts in high-action scenes (4.7 Mbit/s), and LS5 appears similar to a medium-quality video download (2.8 Mbit/s). JVC's HM-DH40000U and SR-VD400U were the only units to support LS5 recording. As a result of all these different speeds, the tape labels are a bit confusing for the consumer. D- VHS
VHS
was originally a standard definition format that recorded at the STD speed. When High Definition recording and HS speed was later introduced, it required twice the amount of tape. For this reason, a DF-240 will record 240 minutes of standard definition, and 240/2 = 120 minutes of high definition. When reviewing the table, note that the digital speeds HS and STD are equivalent to the older analog speeds SP and LP.

Issues and advantages[edit] There are technical issues with compatibility between recordings from Mitsubishi and JVC
JVC
D- VHS
VHS
decks. PAL and NTSC
NTSC
recordings are also incompatible. Very few models are available to the world market and sales of this format have been weak; correspondingly, prices have remained high for both VCRs and media, contributing to low demand. Also hurting demand, say D- VHS
VHS
advocates, is poor marketing, resulting in low consumer knowledge of D-VHS's advantages and capabilities. Another primary roadblock to expansion, is the D-VHS's input limitations. The FireWire
FireWire
input is the only way to record high definition content to tape from an owner's TV, but very few TVs have FireWire
FireWire
connections (like Pioneer PRO-930HD/1130HD), and cable boxes with FireWire
FireWire
have to be specially requested from cable companies. Satellite FireWire-equipped boxes are rare or nonexistent. Existing tape media is bulky and more expensive than hard drives. Although cable companies are gradually switching to the H.264
H.264
codec, this should not be an issue for D- VHS
VHS
units since they can act purely as data stores (like a hard drive but using tape instead), and thereby pass the previously recorded H.264
H.264
data directly to the Set-top Box or TV (via i.Link/FireWire). Another alternative is a lengthy transfer to a computer for viewing. Finally, since machines will soon no longer be manufactured, maintenance of current recorders may prove difficult. D-VHS's primary advantage is that it is still the best way to archive encrypted high definition material from cable programming. Cable, satellite companies, TiVo, and PCs equipped with cable card tuners all offer high-definition digital video recorders, but archival has proven to be an obstacle, as proprietary boxes have restrictions on moving encrypted content. Outside of D-VHS, only HD capture devices that use an analog conversion process, such as the Hauppauge HD PVR and Elgato EyeTV HD, have enabled removal of encrypted content off many of the above proprietary boxes. These HD DVR's use an analog conversion process, producing slightly degraded but still high definition grade recordings. D-VHS, on the other hand, does not need to take advantage of this so-called "analog hole", since D- VHS
VHS
makes a pure bit-for-bit recording with no conversion necessary. This is made possible by compliance with CCI flag values carried by the digital streams, wherein only D- VHS
VHS
is allowed to digitally move recordings of content originally flagged as Copy Once off of a DVR device and onto a D-VHS tape. This programming that complies with the CCI flags then marks such material on the tape such that no second generation copies can be made from the tape itself, though additional copies can still be made directly from the original DVR unit to additional tapes. Monthly rental fees to cable, TiVo, and satellite are also less with D-VHS.[clarification needed] The JVC
JVC
D- VHS
VHS
deck released in the UK, was not a bitstream recorder, although it did have a FireWire
FireWire
input. Instead it is best thought of as a digital recorder for traditional analog inputs such as domestic analog TV and digiboxes for digital broadcasts. The deck was able to record D- VHS
VHS
signals onto S-VHS
S-VHS
tapes, which made it a cost-effective source of high quality domestic recordings (USA version also allows use of cheaper S-VHS
S-VHS
media). Pictures were noticeably superior to S-VHS
S-VHS
and were essentially transparent when compared to an off-air source. Using the LS3 mode, approximately 17.25 hours of digital video could be stored on a S-VHS
S-VHS
E-240. The deck's biggest shortcomings were the lack of a DV output and, perhaps more crucially, the lack of RGB input via the SCART
SCART
connector. NTSC
NTSC
versions had component outputs. D-Theater[edit]

D-Theater logo.

In 2002, prerecorded D- VHS
VHS
cassettes were sold under the brand name D-Theater in the US. While D-Theater is a D- VHS
VHS
tape, it is incompatible with D- VHS
VHS
decks without the D-Theater logo. They provide content in both 720p
720p
and 1080i
1080i
as well as at least one Dolby Digital audio track. Supported films studios include 20th Century Fox, Artisan Entertainment, DreamWorks, and Universal Pictures. D-Theater provides much better audio and video quality than previous formats ( VHS
VHS
and DVD), and there isn't a big difference comparing to Blu-Ray Disc.[citation needed] D-Theater does have region code restrictions. There are 3 known regions; 1 for the USA, 2 for Japan, and 3 for South Korea.[1] There has never been a D-Theater video release in region 2 or 3.[citation needed] Region code hacks for Japanese decks have been performed to support playback of US titles. The last film available was 20th Century Fox's I, Robot.[citation needed] This title was a surprise to many as there were no prior announcements nor any indication that the title was available. It was originally available only on JVC's D- VHS
VHS
store in late 2004 and no other distributor had it (not even Fox itself). A couple of weeks later they started trickling out to more distributors after much delay and confusion about its existence. Alien vs. Predator was announced to retailers as also being released on the same day as I, Robot, but Fox later announced that Alien vs. Predator was never shipped to retailers. Most tapes have built-in copy protection mechanism (DTCP, also known as "5c") (copy never) that disables copying via FireWire. HDNet productions and 2929 Entertainment
2929 Entertainment
via Magnolia Entertainment did provide some of their original content on D- VHS
VHS
but without copy protection. Many of the tapes have an introduction by the owner Mark Cuban encouraging the viewer to make copies of the program in order to help distribute them. DTS[edit] Additional tracks may be included on D-Theater in other sound formats such as DTS. However, only the newest D- VHS
VHS
players like JVC HM-DH40000, HM-DH5U, HM-DT100U, and Marantz MV-8300 include alternate audio track capabilities. DTS D-Theater D- VHS

Rare D-Theater tapes[edit] When Lionsgate bought Artisan, a number of titles that were supposed to be released were cancelled. Some of them were Dirty Dancing, Basic Instinct, and Total Recall. 20th Century Fox, while experimenting with DTS, did test tapes of Phone Booth with DTS. There are also a number of Universal Studio test tapes without DTS tracks, but the released versions contain DTS without that fact being mentioned on the packaging. These DTS tracks were probably late additions. All of these examples of preproduction/review/test tapes have been in the hands of various D-Theater collectors. Fox was set to release Alien Vs Predator on D- VHS
VHS
the same day it released I, Robot on D- VHS
VHS
and claimed the title to be available on their retailer site. The title never appeared on store shelves and was eventually taken down from Fox's site as a D- VHS
VHS
release. It is unclear why the title was never released and if any copies were produced or made it out to the public. If copies do exist it would be the rarest D- VHS
VHS
title. See also[edit]
