Just Add Power HDMI over IP - techncial discussion


Nded

Recommended Posts

Nice Nded,

Since JAP appears to be so responsive to user/installer requests, I wanted to make sure there wasn't an update regarding the IR direction coming soon. I would hate to buy it, and get hosed in a month.

My suggestion would be to outfit both the transmitters and receivers with IR in/out capabilities and add a switch to control the direction. This would keep the current users happy (IR from receiver to transmitter) and make C4 users happy (IR from transmitter to receiver) thus saving a separate cable run/or splitting a current cable run for IR control.

I was wondering if any of the JAP guys can tell us if there are any plans for other types of interfaces on transmitters and receivers in the works. I'm thinking specifically about component + digital audio and/or component + stereo. I am considering the JAP solution, and in my particular situation have an Escient media manager (with 5 Sony 777ES DVD Changers behind it) that doesn't have HDMI as a potential source for a transmitter and a Slingbox Pro with no HDMI as a potential receiver. I know there are adapters out there to do a conversion on each end, but that can cost as much or more than the JAP receiver and just adds another point of failure in the system. Also, if I have to go that route, how will the receiver unit know what resolution to output to the device on the other side of the adapter?

Do you have any recommendations for a standard def display in a deployment using your system? I know, I know... it's not my choice to keep that TV, but it happens to be a TV built into the door of my LG fridge in the kitchen, so replacement is not really much of an option.

One other question is that I know the receivers have built-in scalers to change the stream into what the display natively supports, but do the transmitters have have any upscaling capability at all?

Thanks,

Steve

Why not just use a component switcher, like the one Sony and many many manufacturers make? Component technology is sunsetting in a few years, and I doubt JAP would want to invest in it, and it goes against their entire concept of "HDMI over IP."

3finger, I actually already own the Sony CAV-CVS12ES component video switcher. I like the idea of the scalability for growth with the JAP solution, but you hit the other main reason on the head. With what I am reading about the analog sunset at the end of this year, I am concerned that one or more of my sources will implement the Image Constraint Tokens and reset my component distribution back to standard def for that source.

Theoretically, the CVS12ES can use 1080p over component, but even my Sony 7000ES blu-ray changer will only output 1080i over component outputs. The other thing that isn't really documented on the CVS12ES is that there is no scaling at all, so if you have a smaller display that can't accept a 1080i signal, you'd have to set all of your sources to the resolution of the lowest common denominator.

Now, the concerns center on the JAPs not streaming lossless audio, which leads to crazy cabling to split digital audio cables from sources to each of the receivers for rooms you want surround sound in, which adds more cost and complexity to the design. Not to mention that I have sources (2 Tivo S3 HD units come to mind) that only have optical out, not coax. And you run into the possibility of not having enough digital coax audio inputs on each of the HT receivers, and so on, and so on, and so on. Trust me, my mind has been going around in loops the past few days trying to figure out how to use these in my particular situation and the complexity and cost of the adapters, splitters, etc. is the limiting factor. Other fear is that since the the JAP guys are so responsive (and that is a good thing), I don't want to buy a couple thousand dollars of transmitters and receivers to only have them release newer versions a month or two later that might fix the issues that I had to use ancillary products to work around.

Ed- Same MSRP of $1299?

Yes, the V2 Rackmount Transmitter price remains the same as the V1 model. It wouldn't be right to charge more for fixing what the pro installers pointed out as a "design flaw".

Ed' date=' comment on IR direction?[/quote']

I can comment since i am 99.99% sure of what Ed will say.

its possible future revs will have the IR paths resolved

I would advise you that changes to the IR and remote control aspect to HDMI over IP are not our top priority, and probably won't be addressed for some time. We do hope to come up with a more appealing distributed remote control solution that would appeal to C4 users at some time in the future, but for now the use of the dry pairs (blue/brown for typical 568A or 568B UTP cables) is the most convenient solution to this requirement. Speaking directly to SRHAMY, no, this isn't happening in the next few months.

Hey JAP guys,

Another suggestion for future hardware revisions. I work for one of Cisco's largest resellers in the world, so this idea comes from a few different product lines in which they've implemented something similar. You could sell a rack-mount chassis, that was essentially bare metal except for a backplane that's sole purpose was to provide DC power. Then, slightly redesign your individual transmitters so that they can be used stand-alone with an external power supply *OR* slide into one of 3 slots in the front of the chassis. It's not a new idea... like I said, Cisco has a couple of products that are designed that way. Plus, I have an HP HTPC with a personal media drive bay which is essentially a hard drive in an external USB enclosure that can be used with an external power supply + USB cable or slide into a slot on the front of the PC that has a PS and USB jack at the back of it.

You can sell the chassis for $250, still sell the transmitters for $350/each, but that gives the user the ability to add transmitters as needed one-at-a-time. Another benefit is that if you were to offer different versions of your transmitters in the future (i.e. ones that supported lossless audio, or had component + digital audio as interface types), the end-user could mix and match and/or upgrade transmitters on a per source basis. Win, win, win in my book :D

Attached is a picture of something similar to what I am suggesting. The top 4 items are modules that can be stand-alone or 2 of them can fit into the 1U rack-mount chassis at the bottom of the pic.

Thanks,

Steve

I hope this isn't a stupid question...

When I finally get my system setup, I imagine one of the most utilized features I will take advantage of will be one source to "All Zones". Whether it be wanting to have the TV show I am watching be on every TV while I wander around the house (cleaning or whatever), or hosting a party for a football game, it seems like this will be what I will want to do most often. I'm curious about something that I hope the guys who are using JAP's products can comment on.

I have a fuzzy recollection of reading something about there being a limit on the number of keys or tokens that a source generates. It had something to do with either HDCP or ICT, but I don't remember the details. It could have been an article about the analog sunset and Image Constraint Tokens. Sorry, but I am definitely not an HDMI expert, so I don't understand all the ins and outs of these methods to comply with DMCA, or whatever...

Have any of you run into a situation where not all of your displays will show the source material due to exceeding the number of keys or tokens or whatever in a distributed HDMI system? I guess along the same lines, is there anything coming down the pike that might limit the number of displays that can watch a particular HDMI source?

Thanks,

Steve

The Just Add Power solution is able to overcome the key limitation of such devices. There are completely legal HDCP compliant ways to do this that are approved by the HDCP Licensing authority which we have imbedded into the Just Add Power solution. Even if your cable box only has only 1 key, we can show it on all your screens (as long as you have valid HDCP keys in the monitor).

Very cool! Now that I did not know. I had no idea you could overcome the limited number of keys. I was going to reference a list of hardware and how many keys it generates, but now I don't need to because it doesn't matter!

Ok, first post on this site, I realize, and maybe this has been answered elsewhere but...

It appears as though the MSRP on the V2 rackmount Tx went from $1299 to $1999...?

You are cofusing V2 vs 2G.

1G Rackmount V1 - built with an IT mindset, ports on the front, power on the back. $1,299 MSRP

1G Rackmount V2 - convertible design. Wings on either side, power cord can be moved to either side. $1,299 MSRP

2G Rackmount - a totally different technology. $1,999 MSRP

V1 and V2 prices are identical as I posted originally.

Imagine JAP controlled by an Alexa skill...

Anyone seen a demo?

You are like the neighborhood dog running around and peeing on every shrub. You dug this up from 2010 for what reason? Please stay in your lane.

Because it's relevant.

Alexa controls via IP.

JAP is IP controlled.

AV control is currently Alexa's weakest link though this is changing rapidly.

It's part of the puzzle putting together an entire voice controlled Alexa house.

Cheers!

Have some respect for forum etiquette. Start a new thread.
