JVC HM-DH4000U S-VHS/D-VHS HDTV Recorder
The JVC HM-DH4000U S-VHS/D-VHS HDTV Recorder, D-VHS or Digital-VHS is the format HDTV was waiting for. In fact, it is the only medium and format currently capable of recording digital content of all ATSC (Advanced Television Systems Committee) broadcast standards in the U.S., from SDTV (Standard Definition) to HDTV (High Definition). Up to six times better quality than DVD, the incredibly high read/write speed (28.2Mb/s in HS mode) of D-VHS makes it possible to record HDTV broadcasts, while the huge storage capacity of an 8-hour D-VHS cassette (50GB) allows you to record up to 4 hours of HDTV - whereby an entire HD encoded film can fit on a single cassette, with room to spare.
Since D-VHS can record any type of broadcast (even analog), you can record, for example, up to 24 hours of cable programming on a single D-VHS cassette. Lastly, Since D-VHS uses the same tape transport mechanism as regular VHS, it can record and play back analog VHS and S-VHS tapes as well, ensuring complete compatibility with existing tape libraries
Built-In HDTV Compatible MPEG2 Decoder
High Definition set top box is compatible with a High Definition Television capable of displaying 1080i (1080 x 1920) and/or 720p (720 x 1280).
28.2Mb/s for up to 4 hours of HDTV recording, digital bitstream recording/playback.
14.1Mb/s for up to 8 hours SD recording, digital bitstream recording/playback.
4.7Mb/s for up to 24 hours long-time recording.
For up to 40 hours long-time recording on to a DF-480 cassette.
The video on D-VHS tapes is uncompressed, so it's enormous. For example, a 75GB hard disk can only hold 30 minutes of the video.
5.1-Channel Dolby Digital
D-Theater HD software delivers powerfully realistic home theater sound, because D-VHS's audio data transfer rate accommodates 576Kb/s, close to the full spec transfer rate of 5.1-channel Dolby Digital. While other formats may offer 5.1-channel surround, only D-VHS can bring out all of the subtle nuances and dynamic impact of those 5.1-channel movie soundtracks. Down-mixed 2-channel Linear PCM output is also supported, in case your audio system doesn't have a Dolby Digital decoder. Either way, the optical output makes it easy to connect and enjoy superior audio performance on your theater system.
Top-of-the-line picture performance, which includes several important technologies:
- A TBC (Time Base Corrector) digitally removes jitter from fluctuating video signals to deliver a stable picture even on old tapes. Also eliminates color distortion caused by jitter in the color signal.
- 3-Dimensional Digital Circuit with Frame Memory creates a solid base for new digital technologies with a 4MB memory.
- Digital YNR/CNR removes noise to improve the S/N ratio by approximately 3dB.
- Precise Digital 3-D Y/C Separation improves S/N, reduces image border dot interference and yields better quality moving images with a Digital Comb Filter.
Video Navigation with Title & Category Input
Video Navigation function makes program access and tape library management a breeze. This function builds a table of contents on every tape you record, assigning a unique number to each tape, and lets you input tape and program titles (up to 2000 titles). The system stores all data in memory, allowing tapes to be sorted by tape number, date and category, for pinpoint location of the program you are looking for. Just choose the desired program from the on-screen list, and the VCR will rewind and play it.
Super VHS-ET (S-VHS ET) Expansion Technology
Recording allows the broader bandwidth Super VHS (S-VHS) quality signal to be recorded on standard VHS (video home system) tapes. (High-grade tapes are recommended.).
MPEG-2 Codec for Digital Recording
The built-in Standard Definition MPEG-2 encoder/decoder or CODEC function enables D-VHS digital recording from NTSC analog sources, as well as DV MPEG-2 conversion recording from a connected MiniDV video camera. Also, when dubbing from an external analog video source such as a camcorder or VCR, JVC's Frame Synchronizer/TBC eliminates jitter from the input signal to produce high quality dubs that can actually appear to surpass the quality of the original.
HDTV Component Video Output
(Y,PB,PR) Terminals let you connect to an HDTV or projector equipped with Component input, so you can enjoy the full quality of D-Theater software as signals are decoded by the built-in MPEG-2 HD Decoder.
i.Link (IEEE-1394) FireWire
This IEEE-1394 compliant digital interface allows the connection of a digital settop box or HD and SD camcorder for the transfer and recording of HD and SD digital signals.
DV and MPEG Input
