Using a DVR to delay a live feed at church

I am researching this question for an AV person at my church.

He needs to delay a video/audio feed from the main sanctuary to a
smaller chapel in the same building. Right now, the sermon happens in
the main sanctuary and is projected on a screen in the smaller chapel
in real time. Often the feed begins before the the chapel is ready,
and he would like to delay it.

Would a DVR work for this? I'm assuming the church uses composite
video and line level audio from the sanctuary to the chapel. Is there
a DVR that would accept those inputs and allow him to play back the
beginning of the sermon as the rest of it is being recorded?

Thanks.

Sounds good to me. You can start the recording, pause it, rewind it, or
whatever you want to do with it.

Something like this:

I believe the Philips models have the appropriate inputs for your needs,
but please double check this particular model's specs.

I am unable to find any info about this unit other than what is says at
the Surplus Computers web site.

I looked at other Philips TIVO units, and they do accept composite video
and L/R audio, but I can't vouch for this particular unit.

My LG has composite inputs. But perhaps there's a PC answer. That
would help you do other things, like online streaming and archiving.

Any DVR should work for this
Before you say that for certain, look at the inputs TIVO DVR's have. I
think they are limited to RF and antenna inputs, and don't necessarily
include composite and audio inputs.

Both my Tivos have composite (and S-video) inputs. Wiki says all of
them do. While it isn't impossible that Tivo or somebody else put out
a DVR without composite inputs, it seems extremely unlikely. Note that
composite inputs are also useful for those using satellite or cable boxes.

Many DVD recorders also allow time-shifting and may be a cheaper option.
The one I pointed him to is $19.99 plus shipping and he must add a hard
drive.

Noone had mentioned DVDR yet so I wanted to put it out there. An out
of the box solution might be appealing even if slightly more
expensive. Plus in this particular instance a DVDR might even be more
useful than a DVR since it allows for playing DVDs and archiving services.

That $19.99 from surpluscomputers also seems a little odd. It show two
different model numbers, neither of which appear to be correct (google
only finds them at that site). It says it is Tivo but that it doesn't
require Tivo service; this was true of Tivo Basic but those units all
had DVD or DVDR which this unit doesn't.

If it is a real Tivo adding a disk is non trivial since you will also
have to obtain and install Tivo boot images. The Tivo hacking sites
describe the process but unless it has changed recently it requires a
fair amount of technical knowhow. You can buy preloaded disks from
weaknees.com but that is likely pushing the price above a cheap
non-tuner DVDR.

If you can find an old replayTV box it should work. The only thing is
someone would have to be in remote site to delay or pause/play the live
feed. I suppose you can have a small tv monitor for the live feed then
output it, to the RPTV which then re-broadcasts to the projector.

I got a message from the AV folks that they had bought a TiVo, they
think they can make it work.

You are right about having an operator in the remote site (chapel); they
do this routinely to oversee the live projection and PA system.

Thanks to all who contributed ideas.

The reason I mentioned a ReplayTV over a Tivo, is the older units and some
later unit have lifetime subscriptions built in. Unlike the Tivo and later
model RPTVs, they are doorstops without the subscription. You might want to
look into MythTV as well, it's free program, and there is a NG dedicated to
it's support. Look for Wes Newell, he's the author of MythTV.

Using a DVR to delay a live feed at church
 

Some of the responses here mention home electronics solutions, such as TiVo
or ReplayTV. Another alternative is to look at security DVRs. Maybe the
church already has a multi-camera security system with a spare channel. If
not, a low channel count DVR with playback while recording capability should
work.

Good point, but most security DVRs split the bandwidth, depending on the
number of cams. Typically a 8 cam setup on 160fps (frames per second)
system, will only record 20fps per cam. Though the controls may be a bit
cumbersome, Tivo or RPTV DVR are much simpler to use.
