DTV Tuner PC / Mac Cards, and USB DTV Tuners
Capable of DTV reception and Clear QAM Cable, recording and playback. For in depth discussion of this aspect of HDTV recording, please see the AVS HTPC Forum. For digital tier and premium cable, CableCARD PC's are available.

Blu-ray Burner
With a Blu-ray burner installed in your PC, you can make BD disks from a variety of sources, including your HD camcorder. For in depth discussion of this aspect of HDTV recording, please see the AVS HTPC & Blu-Ray Forum for details.


HDTV Camcorder
For in depth discussion of this aspect of HDTV recording, please see the AVS Camcorder Forum.

Component video & optical audio to PC
Hauppauge's HD PVR will record High-Definition for making real-time H.264 compressed recordings at resolutions up to 1080i. HD-PVR records HD component video and DD optical audio. The recording format is AVCHD, which can be used to burn Blu-ray disks.

Firewire Source to Microsoft PC
For in depth discussion of this aspect of HDTV recording, please see DVHSTool and other topics in the HDTV Recorders Forum.
PC recording of HDTV is made possible by Microsoft Windows XP & Vista native support for IEEE1394. The PC can be used as both a storage/ retrieval device and a playback device. The PC's peripherals (hard drive, DVD drive) are used to store the HDTV signal that comes from compatible sources. Used as a retrieval device the stored HDTV signal is played back through the IEEE1394 to a display device or other storage / communication device. Used as a playback device, various hardware and software HDTV signal decoders can be used to present HDTV video and audio for viewing.

To use the IEEE1394 interface in WinXP, specific support of the particular model of unit with the IEEE1394 port is required. That is, the presence of a IEEE1394 port doesn't imply compatibility with Windows XP. Various drivers and applications software are required and available to use the JVC and Mitsubishi DVHS decks with Windows XP. For example, even though one "OTA only" model of the Samsung HDTV has IEEE1394, it cannot be used with Windows XP since there are no mating drivers. The 169time equipped DTC100 can be used with Windows XP.


Firewire Source to Apple Mac
A FireWire equipped Apple Mac running Mac OSX 10.5 Leopard can function as an emulated DVHS deck for both recording and playback of OTA HD broadcasts. To accomplish this you will need the demo application VirtualDVHS2 which is included with Apple's Firewire SDK 20. VirtualDVHS2 should work with a variety of devices including most Mitsubishi HDTV's, the Samsung SIR-T165 STB, Mitsubishi HD-2000U and JVC DVHS decks. The FireWire equipped devices control all recording and timer functionality and the Mac simply acts as a DVHS deck. The improved GUI of VirtualDVHS2 simulates the front panel of a DVHS deck including record and playback buttons and a counter. Please note that the VirtualDVHS2 demo is really a refinement of a proof of concept rather than a supported Apple application although some forum members have had good results. Source code is also available so some enterprising developer may be able to wrap a polished GUI around this and ship a commercial product.

An AVS member has developed software, iRecord (http://www.ammesset.com/), using Apple's latest AVCVideoServices framework to record 5C copy-freely content from Motorola and S-A STBs equipped with FireWire. The software allows for timed-recordings and tuning channels.

The FireWire SDK 20 which includes VirtualDVHS2, source code, and other programs such as AVCVideoCap and DVHSCap can be freely downloaded from Apple developer site at the URL below. Be sure to read the readme included with VirtualDVHS2 for configuration info.

FireWire SDK 20 (ftp://ftp.apple.com/developer/Development_Kits/XFireWireSDK20c.dmg)

My sincere thanks to AVS members rcliff and jsb_hburg for providing this information.

Firewire Source to D-VHS
Digital VHS is capable of recording and playing back the full 19+ Mbps data stream of ATSC HDTV broadcasts, including Dolby Digital 5.1 audio. There are different varieties of D-VHS decks, but all are essentially ‘bit buckets’, capable of recording HDTV and playing it back identically to the original broadcast. Typically, an outboard source provided the HDTV signal via Firewire to the D-VHS deck, with only one D-VHS unit having a built-in DTV tuner. This approach also allows for HDTV copies using Firewire recording from D-VHS to D-VHS, D-Theater (prerecorded movies) excepted.

Latest update complete.

As always, additions, suggestions, and corrections are welcome.

A sincere thanks to everyone at AVS who has contributed to this topic over the years, in particular AVS member bfdtv.

Should the Maggy/Funai deck really be included in the list since it only has a SDTV tuner/recorder and since this is a HDTV forum???
It does records a digital channel, but not in HD. ;)

Should the Maggy/Funai deck really be included in the list since it only has a SDTV tuner/recorder and since this is a HDTV forum???
It does records a digital channel, but not in HD. ;)I updated the table with the sub-heading for SD Recorder / HD Recorder.

We see regular posts on the Maggy from new members who think that it supports HD. Many of these members don't understand the difference between actual HD and upconverted SD. I thought adding it to the table might eliminate some confusion.

Thanks. We see regular posts on the Maggy from new members who think that it supports HD.Probably the same ones that think those CECBs' deliver HD. ;)

I updated the table to include the latest Moxi announcements.

What about Slingbox's, HDHomeRun network tuners, adding a software section, Hagauppe HD-PVR, and marking discontinued/obsolete hardware?

Speaking of obsolete formats-I just bought a NIB JVC 40K D-VHS deck off Ebay.

Software section should reference minimally-CapDVHS, VRD, H2M, M2R, TSR Pro, TSPE, 1394 Drivers.
Let me think of how to present the info.
A guide to extraction (1394 & TivoDesktop) would be helpfull for newcomers.
Blu-ray recording off the EU/JAP decks would be intresting if anyone has these boxes, though not avaliable in the USA yet (to my knowledge).

Persnally I'm cappping off 1394 & HDHR QAM&ATSC as I type this-6 HD channels.
