Here were the questions (followed by my answers) from the webinar:
Q. I was wondering if you talk a bit about optical HDMI cables and if there is any issues with optical HDMI cables longer than 50 meters. I'm looking at running a 60 meter cable, but most manufacturers only have up to 50 meters.
A. Although AOC cables can carry signal much further than a traditional HDMI cable, AOC cables are still susceptible to issues with extra long distances. In fact, the longest AOC cable that we sell is 40 meters (AC-BTAOC40-AUHD). If your cable run is longer than that I would consider an HDMI extender.
Q. Can you speak on the durability of optical HDMI cables? When doing wire pulls, how does optical HDMI compare with Cat5/6? Do we need to be extra careful pulling optical HDMI, in comparison to Cat5/6?
A. I can tell you from my personal experience that the Bullet Train AOC cables are very durable. Treat them as if you would treat any HDMI cable. As long as the cable isn't damaged, smashed, cut, tied in a knot, etc. it will be OK. One thing to keep in mind is that they are directional, so make sure you install them in the proper direction. There is a chip in the HDMI connector in each end of the cable, so you may want to handle the ends with a little more caution than normal.
Q. Use of AC-SC1-AUHD wouldn't work in residential with UHD content as it's not only 4K resolution it's also color space and HDR, right?
A. The AC-SC1-AUHD also is built to handle any HDR content in any color space as long as the total bandwidth is 18Gbps or under.
Q. Does the AC-SC1-AUHD provide color space and HDR-SDR conversion too? Would this not be required with a UHD source and one UHD display (4K / 2020 / HDR) and one 1080p / 709 / SDR display
A. You are correct...you could use an SC1 in this situation. When downscaling from UHD to HD for the HD display, the SC1 will strip away all of the HDR metadata, and the entire signal is converted to 1080p/SDR/rec709. The brand new SC2 can downscale all the way down to 480p if needed.
Q. What do you recommend to test CAT cable for HDBT extenders? I know a few companies have specific HDBT testers. We have a CAT verifier but have had situations where it verifies ok but HDBT has issues
A. I would definitely recommend a proper HDBaseT tester. Traditional CAT cable testers are great for testing continuity in the cable, but they can't quite tell us everything about the high frequencies that we see when passing video information over the CAT cable. The last thing you want to see is a failure within the cable after it tests ok!
Q. What is your suggestion for fiber? How many strands?
A. I have personally seen cable with 1 - 6 strands of fiber. Based on what I have seen so far, I would be installing a cable with at least 2 strands. 1 can carry A LOT of data, but who knows what the future holds! We may see a day where 2 strands are used for double the bandwidth, and I am a big proponent of future proofing. At the end of the day, it really depends on the requirements of that particular install and budget (the more strands within the cable the more expensive the cable becomes). As far as clarity I recommend AT LEAST OM2, preferably OM3. Don't forget conduit! In case 1 or 2 strands isn't enough in the future, having conduit installed makes it very easy to pull a new cable through!
Q. What about "stabilizers" that are advertised to make older HDMI cables work for UHD?
A. I have not personally seen anything like that. We have seen issues with HDMI equalization in devices and cables, and products like the SC1 will help in those situations.
Q. Carrying Atmos to an AVR which is not capable of playing it is pointless, much easier to just run optical
A. I would agree if the AVR is not capable of Atmos there is no point in sending the Atmos signal, but if the AVR supports uncompressed high resolution audio formats I'd like the customer to be able to experience them. Uncompressed high resolution formats such as Dolby TrueHD and DTS HD Master Audio require an HDMI connection.
Q. What is the HDCP version on the output when you are running a 4K TV and an older AVR at the same time. The AVR cannot deal with content with HDCP 2.2 regardless of the resolution.
A. The latest version of HDCP that is found in current devices is version 2.2. If your AVR is HDCP 1.x, it will not be backwards compatible and you will have handshake issues. Time to either replace the AVR or simply stick with Toslink or Digital Coax for audio.
Q. Can the scalars "down color" when some sets are 4:2:0/8-bit and others 4:2:2 or higher at 10- or 12-bit for the likes of Dolby Vision. Both the AppleTV 4K and Oppo UDP-203 and UDP-205 output at 60fps and higher color sampling
A. The SC1 specifically has several preset EDID options (including HDR), or you could copy a known good EDID from your display. You could use the SC1 to manage the EDID so the source responds accordingly. You could also manually set up the source to match the specs of the display.
Q. Will there be firmware updates to the Murideo for HDR-10+?
A. Not at this time, but we will definitely keep everyone posted if that happens. Any time there is a FW update to the Six G, check out this link to see what's new.
Q. Please explain more about why not to use EZ RJ45 ends, since they have the wires go through the connector and get cut off when crimped.
A. RJ45 EZ ends are notoriously unreliable, especially in video applications. Our tech support team runs into bad connectors so often that they have made it a standard practice to have installers re-crimp regular ends as part of the troubleshooting process.
Q. Do you have advice or a preferred setup when you have a mix of multichannel (Atmos) AVR zones and 2 channel zones where you want extracted audio into the multizone audio system. Maybe a 6x12 size system, with ARC as well from the smart tv's back to the audio system
A. A lot of our products support extracted audio. Be sure to set the device that you are extracting audio from to output 2ch PCM audio. Otherwise you will only hear the front left and right channels of a surround mix. If you are not using of of our devices to extract audio and you need to downscale, you could use our audio downmixer (AC-ADM-AUHD). To get audio from the smart TV back to the AVR via ARC, you could use of our extenders that supports ARC such as the AC-EX100-444-KIT
Q. With 48Gbps coming, when are we going to simply eliminate HDMI and go to direct fiber optic ends?
A. Great question! I don't see that happening any time soon as HDMI has firmly planted it's foot as the standard connector for A/V applications.
Q. How do baluns and devices that only have 10.2Gbps bandwidth claim they pass 4k UHD?
A. Anything over 10.2Gbps over CAT cable MUST be compressed. Our products use a proprietary compression method called Invisible Compression Technology (ICT) which assures that the picture is artifact free after the signal is decompressed at the end.
Thanks for watching! See you on the next one!
