Can you record from 169Time to Hipix/MyHD?

453 Views 15 Replies 5 Participants Last post by  h2ofun
This is an interesting solution to me. About $1400 or so for all the peices (I already have a DTC100) and I have a fast computer and lots of HDD Space. My question is.. would this actually work? Can the 169Time box output via firewire to one of the HD cards?


Thanks!

The 169Time DTC100 will output OTA signals directly to your computer via firewire. It will also accept signals from the computer via firewire for display purposes. You can think of it as an external HiPix/MyHD. You either get the internal version (HiPix/MyHD) or external version (169Time DTC 100). No need to get both.


Remember that this will only work for OTA signals though.

Question: why not? If the AVX-1 can output to DVHS machines, can't the computer capture the unencrypted (I'm assuming) transport stream? Or does the AVX-1 actually encrypt it's output?
Firewire is peer to peer. AVX-1 will not allow a handshake with the computer. You would have to write something similar to a network sniffer, except for firewire packets, if you wanted to capture that data. The data however is not encrypted.
Okay, why will the AVX-1 not allow handshake with the computer? Unless I'm crazy, the AVX-1 is just a small linux box itself, right?

Simple,


Any hardware device you connect to the computer requires a driver. XP comes with drivers for DVHS tape devices. 169Time's DTC100 identifies itself as a tape device to the computer so you can use XP's build-in drivers for it. AVX-1 does not do that.


One can possibly write a driver for the AVX-1 to make the XP computer look like a DVHS tape device to the AVX-1, but no one has offered to do it yet.
leszek1 - sure. But the AVX-1 has to have a "driver" which recognizes the DVHS machines, since it works with those, right? So the Driver which makes XP look like a DVHS... ?
Uhhh.. show me where I said it was windows.


What I'm saying is if there's a driver that can make an XP box look like a DVHS, why won't the AVX-1 send it transport streams?

That's the problem. There is no such driver. You're welcome to write one if you have time.
Interesting. Ron (dr1394) recently explained to me that in the typical use of 1394/DTCP, even if the source wasn't transmitting on the broadcast "channel" (I forget the proper 1394-speak), anything on the bus could listen to its stream, whatever channel it was actually sending on, and that the source would exchange encryption keys with anything on the bus which could "show the proper credential". I was asking him to clear up some misconceptions I had about the protocol (having only read the specs, without programming for it). I was also trying to get him to confirm that a "push" model could be implemented, which is what I'm expecting the Dish 921 to use, since it's been asserted that its 1394/DTCP connections are exclusively for archiving to tape and cannot be used to view a recording on a 1394/DTCP equipped monitor. He grudgingly admitted that such a thing was possible, but couldn't imagine why anyone would do it. I do--to rigidly limit the use of 1394/DTCP so that the studios won't throw a hissy fit about the presence of the connection on your device. If the PVR will only send video over 1394 at its own discretion and will only communicate with peers which it can identify as being VCRs, you don't have to depend on DTCP for security--the PVR can simply refuse to move any program marked "Copy Never" or "Copy No More" over 1394. Of course, it shouldn't ever have any programming marked "Copy No More", but who knows.


By "push model", I refer to a recording paradigm of archiving to tape from a PVR where the PVR controls the recorder, like TiVo's archive function. Sounds like the AVX-1 implements just such a "push", I'll-only-give-video-to-a-VCR model.


Do you have to program recordings through the DTC100 or AVX-1, or can you do a timed recording initiated by the VCR?

The goal is the dtc100 will still do timer control like OTA. Meaning, the dtc100 turns the deck on and off. It works on the japan, but not totally on the US?

Dave:


Timer control on the DTC100HDVR for OTA works 100% on the JVC30k USA, I use it all the time for OTA.


Lon
Lon, yep. 169time would like the avx-1 to act the same way.
