1. I am a bit concerned about the proprietary compression that J+P uses. They are taking a lot of data and compressing it pretty heavily to get it to fit through CAT5e/CAT6. Would anyone be able to comment on the quality of the video for things like HDR and 4k?
2. Also concerned about the scaling for 720p/1080i/P to 4k. I saw a nice TV that I was very interested in but the picture for DirecTV sports was very bad and I couldn't adjust my way out of it. Some of the other, much cheaper, TVs did look better but was just wondering if the J+P system would help or potentially hurt this upscaling.
3. Cost - I 'think' that the J+P will end up being just a few thousand dollars more than an 8x8 matrix for my setup but I also need to put a transmitter and receiver in to take A/V from a family room HDDVD to the central rack system so we can share that source. Do I have to worry about audio syncing with this process? I'm also considering putting an HDDVD in the master bedroom as another source so now I'm looking at 2 additional sets of transmitters and receivers and they don't come cheap
4. My other thought was just to stick with 1080 around the house and do a much cheaper matrix for now. Set up the main TV with 4k and a direct connection to the HDDVD player and AVR and not share that source with the rest of the house. If I did this, it would start the C4 conversion process at a much less expensive starting price and then we could look at modular additions of J+P at a later date.
5. I don't know what I don't know right now. My installer has experience with J+P and fairly large commercial and residential installs but when I asked some specific questions about mixing and matching the 4k and 1080 TVs he wasn't sure since all of the systems they have installed were on 4k for all TVs. This wasn't the programmer though. It looks like this is a heavily advertised benefit of the J+P system but I'm not sure what other questions to ask or things to look for.
Thank you in advance for any thoughts or ideas you may want to share - they are much appreciated!! I see lots of smart and experienced folks on the board and I'm hoping to learn from you!
We use a ton of JAP product (thousands of end points a years) in commercial applications. Our typical installs are in the 15-20 inputs x 55-75 outputs. In these situations HDoverIP is the only cost effective options as a traditional chassis based matrix gets expensive in that type of I/O counts.
1) The 3G products are significantly better than the 2G products when it comes to compression, but it requires significantly more bandwidth (more expensive switches). The original 2G stuff used JPEG2000 compression, I cannot remember off the top of my head what the 3G stuff is using. The 3G stuff is usable in a house, but I wouldn't be using it in a theater or for any critical viewing.
2) Interlaced sources such as DirecTV has always been the biggest issue for most of the HDoverIP solutions that we have tested. They are getting better, but coming from an uncompressed RGB format you will notice a quality decrease. As far as the 4k scaling from lower quality sources, I haven't noticed any issues with it. It is equivalent to what the TV would be doing upscaling the same lower resolution source.
3) COST- This is going to be the biggest issue. You are adding a lot of complexity to the system by going with HDoverIP, with not much added benefit. Our break even for clients is 16x16 systems, if you are under 16x16 I would never spec out HDoverIP unless there was a very specific feature set I needed (Video Wall processing as an example) that I could not do with a standard matrix. To give you an idea I put a Crestron DM-MD16x16 matrix in my house to allow for any future expansion I might need, but I know I will never go over the 16x16 count in this house. If you want to get out of the crestorn eco system, Wyrestorm and a couple others have great 4K HDBaseT options. I went with crestron because of the control system integration and the amount of I/O flexibility with it.
You don't need additional transmitters and receivers for the HDDVD players, you one need transmitters. Transmitter would go in the room locally with the device than patch into the switch in the av closet via Cat 6 Cable.
4) This is how I typically build systems if budget is an issue. Theater and media rooms with 4K content get a local AVR with local 4k sources AND a 1080P receiver fed from the video matrix. You can watch any of your local sources in native 4K with no compression, but you can also access any of the global video sources in the matrix system. I am working on putting a built thread together for my current house system that will go into more detail about this, but it will take some time to get everything together. At the end of the day if you are putting a control system on top of it it will handle all of this to make it work seamlessly.
IMO you are adding a lot of extra complexity by going with JAP or any other HDoverIP solution for such a small system. Make sure the network is setup properly and you are using quality equipment, we use Cisco SG500 and SG500X switches, Mikrotik Routers, and Ruckus APs (Ubiquiti for budget projects that don't headily rely on wifi). They will probably sell you Luxul stuff as part of the package, but I have had issues with it in the past and will not spec or use it on any of my install, but I know other dealers that have had decent luck with it.
