If you hook up an RPTV and DVD player to an A/V receiver for home theater, does the receiver also have to have a Firewire connection in addition to the TV and the satellite box?

Yes. You're going to be buying all new equipment. http://www.avsforum.com/ubb/smile.gif


But Firewire has its benefits. You probably run somewhere between three and six cables just for video input on your receiver. With 1394b, one cable can carry HD video, digital audio in both directions. Using repeaters, you can run Firewire hundreds of feet. And Wireless 1394 will probably be deployed next year. And it's all backwards compatible with the millions of camcorders that have been sold.

Thats something that I never thought of till now. . . what Recievers will have Firewire in them, and will they have to be either 5c, or HDCP compliant?

My Onkyo 989 can be upgraded(updated) to firewire, or so I've heard.

I'm thinking the receivers probably will need to be 5C compliant to pass through the correct signal. OTOH, that actually could have some benefits since we shouldn't see those stupid Macrovision artifacts you get when you plug cables into too many devices. But all of that remains to be seen and is probably somewhat dependent on how well HAVI works.


On the cabling front, I forgot to mention that you can daisy-chain Firewire so you run one cable to your PVR and then run a cable from it to your TV. The Firewire signal works in both directions and potentially among all devices. You can have up to 63 Firewire devices on a single bus which is probably enough for our needs at present. http://www.avsforum.com/ubb/smile.gif

Receivers, heck, the speakers will probably have to be secure if you want better than 48 khz (IIRC) sound. I think they are down rezzing audio also.


But I'm no audio expert. I just remember something I read in the 5C or HDCP specs.

Since that Onkyo lists for $3000, does anyone know if there will be any affordable THX select receivers with Firewire out this fall?

The B&K 307 A/V Receiver (7.1) already has IEEE1394, the MRSP is $3,500, but I think is THX-Ultra.

Tom, I laughed at first when I read that, but now I'm wondering if you were joking or not because I'm not positive.

Sorry, I may be wrong but I wasn't joking. I even remember posting it here somewhere a few months ago when I saw it in either the HDCP of 5C specs.


Curiously at that time I got no response. Maybe everyone thought I was joking then too. But possibly I just mis-read something.


Anyone else remember this?

I went looking and found the following in the HDCP License agreement.

See this

Quote:
3. Compliance Rules for Display Devices. The rules set out in this Section 3 apply to

Display Devices.

.

.

3.3 Digital Outputs. A Display Device shall not permit the output of Decrypted

HDCP Content to digital outputs, except, if a Display Device is also a Repeater,

as expressly provided in Section 5.3 of these Compliance Rules. Notwithstanding

the foregoing, Display Devices may output the audio portions of Decrypted

HDCP Content in (a) analog form or (b) digital form in either compressed audio

format or in Linear PCM format in which the transmitted information is sampled

at no more than the equivalent of 48 kHz and no more than 16 bits per channel.


3.4 No Analog Outputs. Except as otherwise expressly provided in Section 3.3 of

these Compliance Rules, a Display Device shall not permit the output of

Decrypted HDCP Content in any analog representation.
(emphasis supplied)


Note nothing yet says an STB can't output what it wants, but once it IS in HDCP form the license restrictions above apply.

My understanding is that the B and K receiver has an "empty" firewire port on the rear panel. I call it empty as it is not hooked up to anything.
