Why is it that while most HDTVs I've hear of DO own HDMI inputs but not FireWire/i.LINK inputs, _
Hey, will you come back periodically and look at my responses to your answers (as added detail), please?
Thanks, and healthy Christmas,

Answers: Of the few manufacturers that produced Digital VHS (D-VHS) HDTV recorders/players with the sole purpose JVC produced models, of which I’m aware, that were equipped next to an HDMI connection - JVC models HM-DH5U and HM-DT100U. At this point within time, aside from JVC’s HM-DH5U (no built-in ATSC tuner) or HM-DT100U (built-in ATSC tuner,) it is extremely unlikely that you will ever see any new HDMI-equipped D-VHS recorder – there simply isn’t sufficient constraint, which is why all but JVC’s Professional division own discontinued production of their D-VHS recorders. In considerable part the hastily waning interest contained by D-VHS (though D-VHS never developed much of a following in the first place,) have been fueled by the popularity of alternative soaring definition “DV” recordable formats such as hard-disk high definition video recorder and—to a lesser extent—recordable optical disc formats, oodles of which are capable of using the newer, more advanced illustrious definition codecs for video and audio.)
For the many D-VHS owners who own a non-HDMI-equipped D-VHS recorder/player the option are somewhat limited if they desire to view D-VHS tape containing high definition content on an HDTV display that lacks an IEEE 1394 input. There are essentially three option: (1) you can either dig out for a used JVC HM-DH5U or HM-DT100U, in upright condition; (2) purchase a new display next to an IEEE 1394 (aka FireWire(R) or i.LINK) input; or (3) scour the “DV”/ “HDV” marketplace looking for a converter. (I believe Convergent Design manufacture such a product - see the resources below for their URL.) For current camcorder and D-VHS owners looking to playback the widest variety of digital video formats—without the hassle of buying a used HDMI-equipped D-VHS recorder or a hard-to-find converter—I recommend simply purchasing a unknown display equipped with one or more IEEE 1394 inputs (providing such an owner hasn’t lately purchased a new HDTV.) With respect to using a converter, even if you found a converter I would be tremendously surprised if you were competent to successfully playback prerecorded D-Theater tapes when the encrypted video notes would have to traverse two incompatible content-protected digital interfaces. Of course you enjoy one other HD output alternative when it comes to watching your D-VHS tapes, i.e., you can use the analog component video out (if your D-VHS recorder/player is so equipped.)
The purpose you haven’t seen more HDMI-equipped D-VHS recorder/players is that support in 1996-1997, when JVC finalized the exact specifications for the D-VHS standard, the IEEE 1394 digital interface was the singular practical, high-throughput, low-latency, small form factor (SFF,) point-to-point interface standard that was sufficiently robust adequate to support digital audio and compressed high definition digital video; HDMI wasn’t introduced until 2002. Furthermore, during the time of year of time when the D-VHS standard was person developed nearly all digital (DV and HDV) camcorders be equipped with an IEEE 1394 interface. (USB be not a contender because, at that time, the USB 1.0/1.1 interface topped-out at 12Mbit/s, not to mention that the USB interface operates below a different topology than the IEEE 1394 interface, thus ruling-out USB as a viable interface for D-VHS recorders.)
HDMI have some rather luminary advantages over the IEEE 1394 interface, namely HDMI is a synchronous* interface capable of achieve very soaring, sustained data throughput over significantly greater cable length. *(A synchronous interface is capable of inherently lower jitter than an isochronous serial interface such as IEEE 1394.) HDMI is essentially the one and only mainstream resort available to consumers when it comes to the enormous facts throughput one encounters when transferring uncompressed high-definition digital video through a digital interface; by and ample even the latest version of the IEEE 1394 interface are limited to compressed soaring definition digital video bitstreams.
By the way, not unlike the AACS/HDCP DRM copy protection used beside the latest prerecorded giant definition video optical disc formats, most prerecorded D-Theater tapes incorporate a form of content protection call DTCP (aka 5C,) which disables copying through the IEEE 1394 interface on D-VHS recorders.

Hollywood refused to support HD video unless they have some type of technical solution to construct it hard to pirate shows or use a HD copy to create Tapes or Video CD's which can be sold across Asia and Europe.
HDMI is not a simple transfer approaching FireWire, USB, etc. There is software and copy protection features required in it's use.
Digital cameras, camcorders for home use dont use HDMI because they are designed to permit users transfer things around.
Early HDTVs (2004-5 Sharp models for example) have iLink inputs (even two!).
TV manufacturers dropped it because it add cost and HDMI is now the defacto standard for digital a/v.
CableCard go that way as in good health.
