HDMI 4x4 Matrix Swicther VS. Splitters + Switchers

post #1 of 11
Thread Starter 
Dear all,

I have the following system to config:

3/ 4 sources:
(1) Satellite receiver (CanalSat)
(2) Bluray
(3) Apple TV
(4) tbd

3 outputs: TV displays:
(A) Panasonic Plasma TXP50VT50B
(B) Panasonic LCD TXL42DT50B
(C) Samsung UE32ES6710

2 AV Receivers
(i) Yamha RX-A820 linked to the TV (A) in HDMI direct
(ii) Yamaha RX-V373 linked to the TV (B) in HDMI/CAT6

All sources and AV receivers located in a cupboard.
IR signals will be controlled separately via an IR Router; all devices controlled remotely with Logitech Harmony Touch (x3, one for each TV).

Two different configurations for AV distribution:

Scenario 1:
- A 4x4 HDMI Matrix Switcher: CYP OR-HD44E (explorer chip) or CYP OR-HD44S (silicon image chip). Is there an advantage to go for the ‘S’ version: I have been told that it automatically recognises if a the sat receiver crashes and is rebooted.
- All sources connected to the HDMI matrix inputs. The two AV receivers connected to the Matrix 2 HDMI outputs. AV Receiver (i) connected to TV display (A) via HDMI; AV Receiver (ii) connected to TV display (B) via HDMI Cat6 Balun. The last TV display (C) connected to the HDMI Matrix via HDMI Cat6 Balun.
- Is there a risk that the 5.1 audio signal from the matrix will not be converted in Stereo by TV display (C)?
- Is there a risk of switching problems given the double layer of switchers (matrix and remote controls)?

Scenario 2:
- 3or 4no. HDMI splitters (CYP QU14S), each connected to a source.
- Each splitter connected to (i) the 2 AV Receivers (hence acting as switchers), in turn connected to the 2 TV displays (A&B) as above; and (ii) a switcher (CYP EL-41AT) directly connected to the TV display (C).
- By removing the switcher layer through the matrix, there is only one set of switching. hence avoiding to have a switcher run into a switcher. Hence would this config be more reliable/stable with the use of universal remote controls (as splitters do not need to be configured on the Harmony remote)
- The downside is: more devices and messy cables (17 HDMI cables vs. 10 in scenario 1).

For both scenarios, would you recommend to use HDMI CAT6 Balun of same brand as the Matrix/Splitters, i.e. for instance the CYP PU-103 Kit, or it does not really matter (was quoted the Aavara HDMI v1.4 over CAT, but sounds more expensive).

Many thanks in advance for any answers/recommendations between the two possible config.

It's not the matrix and converts to stereo - it's the source itself. When there is a mismatch in audio codec support between multiple HDMI devices, the source will transmit the 'common denominator', which usually means 2-channel PCM. Now, your Samsung TV supports DD5.1 (apparently!), so you're in better shape than most. The limitation you will run into may be the support of DTS-MA on Blu-ray discs.

Using a splitter or a matrix won't make a difference here - they're all connecting the devices via HDMI, and the source will figure out what audio works for everyone. Either dedicate a BD player to your 'primary' area for the best audio, live with DD5.1, or add a cheap AVR to (C) to bring all three zones to the same level of audio support.

No, you simply never switch inputs on the AVR...

Thank you Jeff for your post.

Does your point is :

(i) under sceanrio 1, the remote would have to be configured to opearte the swicth at the Matrix level only, as the AVR inputs will never be switched (as only 1 HDMI input will be used at each AVR). Hence there is still only one layer of switching, at the matrix level; and

(ii) under scenario 2, the switching levels is at the AVRs level (or at the seprated switcher for the display (C))?

Does this mean that each config will be as stable as the other, and hence would you recommend to go for the 4x4 Matrix switcher and configure the remote control accordingly to operate the signal switch at the matrix level (overall less devices, less messy DMI cable config)?

Many thanks in advance.

correct.

Yes, less stuff, less cables, less to go wrong - same basic results. And any HDMI issues you encounter would be the same, too.

Hi Jeff,

In fact, each AVR will also have a SONOS as a source, so if i put the Matrix ahead, there will be 2 layers of switching, which somewhat complicate the requirements for the remote.
I have also been told by my installer, that because there are two layers of switching you wont have a visual representation of the state the system is in, so should there be a missed command it will be much more difficult to identify the issue. Using the splitter Scenario, the AV receiver will give an on screen display informing you of the input it is on.

Furthermore, as I will have once central IR controlled unit shared by all rooms, issues can arise from two people using the system simultaneously in two different rooms. If an ir command is being sent from two areas at the same time to the matrix it will cause neither command to be understood. This then leads back to the point above as there will not be a visual representation of what the problem is, so both users will then have to begin problem solving. This may be solved by the help function on the Harmony, though this is not always the case and it is best to have an indicator of what the issue is.

This seems to be reasonnable argument, but have you or any other person on the forum had experienced similar configurations and hence do you have any opinion on that matter?

Thanks in advance,
Jean-Yves

Have you looked into other remote options? While some will argue that your standard form factor remote is best (given familiarity with physical buttons), you could look into iRule. iRule is a user designed interface that is then uploaded (via an app) to your iDevices (tablets, phones, iPods). This will solve a couple issues for you.

First, you can't control Sonos via the Harmony remote, so essentially you're using two remotes. iRule has a Sonos interface.

Second, the Global Cache hardware can send multiple IR signals simultaneously without any interference issues.

Third, it operates over wifi, thus range and line of sight aren't an issue (or can easily be fixed). For those devices that need IR, you use IP to IR converters.

Is it similar product as the RedEye from Thinkflood?

Yes, but cheaper and probably better. For $50 (or $100 for pro), you get a license for up to three devices. If any of your devices have IP control (such as the AVRs, matrix), then all you need to do is plug them into your router and you're set. If the devices are controlled via IR (TVs) or RS232 (matrix), then grab the IP to IR or IP to RS232 converters and you're off to the races. You design your remote layout via an online interface and then drag and drop the commands for each of your devices onto the remote buttons. One remote button can send several different commands at the same time. That is, you could have a master power button that with a single click will turn off all A/V equipment, lights, close the blinds, etc.

Thanks a lot. Worth having a look at it.

Not really. Any remote an installer would sell can handle this.

True, you would get the OSD from the AVR for each video source if you use the splitters. But you'd still get enough info from the OSD to diagnose regardless - the matrix path would just show one input or the Sonos one.

This is really not a problem.
