Topic: Wireless HDMI What Product? - Page: 2

This topic is old and might contain outdated or incorrect information.

Used this at a wedding about a week ago.. Everything worked flawlessly. Transmitted the live slide show about 250 feet through 2 walls. I already know where improvement can be made at Steve mentioned on that thread. I need an injector to put the audio from my mixer into the HDMI that way the sound will include everything (microphones, etc...) instead of the audio directly from the laptop HDMI out. So, I will probably add one of these soon: https://www.amazon.com/gp/product/B076JR9ZZF/ref=ox_sc_act_title_1?smid=A02384876VMQLMNCOLQ4&psc=1.
Now that I have successfully used this setup I will add it to our list of available enhancements. Not sure how much of a market there is for this; but nice to know I have it in the toolbox.

This is a critical topic for VDJ's. If we, and the video pools are to challange, and beat the current established audio only way of presenting music then we must utilize the fantastic in house video screen systems which more often than not just present sport. Linking into these systems can be tricky and I hook into one such system (10 large screen TV's) using cat 6 cable and HDMI adaptors.. but this method does not offer much flexibility. So I've just bought these https://www.aten.com/global/en/products/professional-audiovideo/wireless/ve809/ second hand and cheaply on ebay. This is an important open, and changing topic which is a cue for the death of the audio only DJ.

I work in the middle of a very famous city at it's critical heart..and I may be the only one (at least at it's heart) flying the video / karaoke flag. I look around and see vast under used investment..one such venue opened last August, they even have an aeroplane dangling from the ceiling and of couse a multitude of high quality TV's and projectors. I look on in awe.

The fight is on !

Note: Don't worry about 4k video stuff..our videos at best are 1080p resolution.

I'm struggling to learn about wireless HDMI transmission. It is a newish technology and there are pitfalls. Comparisons can be made with radio microphones in that the best allow the choice of frequency to avoid interferance. The one I bought cheaply has a fixed frequency around 5.8Ghz. Some of the newer stuff is based on eight selectable frequencies around 5.8GHz. WiFi may operate around these frequencies and cause interferance. There may be other factors which cause problems such as video resolutions. Anyway I'm trying to learn about this since it is an easy way to access large venue video systems. They tend to use a HDMI matrix, maybe something like 4 by 4 or even more complicated.. if you know what I'm talking about and this is our connection point via an HDMI cable.

The above chart give us a typical 8 channel selectable option for a newish wireless HDMI transmision system.
Interesting.. but what frequencies do WiFi operate on?

Notes:
The one I have bought which I'm awaiting is very similar to that owned by MrTDBennett.
You can download an app on your mobile phone which sniffs out the frequencies of WiFi fields and offers a warning if interferance is a possibility.
I wish they would put a HDMI video system connection point in the DJ booth.

The above is a good link which helps with hardware selection.

For those who go in both feet first...

Huh?

“Dynamic frequency selection” is a fancy name for a very basic process. It means that your transmitter is going to analyze all of the frequencies before it sends any data, so that it knows which frequencies have a bunch of traffic on them. With dynamic frequency selection, your transmitter can also tell if there’s a lot of interference on a specific frequency. As a result, it knows which one will transmit your data in the most efficient way possible.

But since frequency traffic and interference are always changing, you need a transmitter that can adapt on the fly. That’s where the “dynamic” part comes in. One day, a certain frequency may offer the best route for your data, but it could be totally clogged the next day. As long as you’ve got a transmitter that’s smart enough to figure it all out, you’ll never have to worry about slowing your data down — or getting in the way of any official business.


This phrase “Dynamic frequency selection” may be expensive but it is likely to offer the best hardware money can buy. Other than that a cheap 8 channel HDMI transmitter / reciever set up may be the best. There are so few reviews and I was not prepared to invest the £85 on an "unknown" ebay item such as this one https://www.ebay.co.uk/itm/5-8GHz-HDMI-Wireless-1080P-AV-Sender-TV-Wireless-Transmitter-Receiver-Audio-300M/123146973272?hash=item1cac21b058:g:SMsAAOSweIlbA38Y:rk:1:pf:0.

Anyway I'm just a learner..what is best?

I'm not supposed to post 3 times consecutively except I think this comment might help.

https://www.aten.com/global/en/products/professional-audiovideo/wireless/ve809/

The above item worked well in my home but in a venue at approx. 40ft (DJ booth to HDMI matrix by the bar) the signal transmission failed.
I don't recommend this item or similar for professional work in large venues.

I did not have time to investigate..just tried and failed.

This may be the most important current topic so I will stay focused.

I have been "smashing it" everytime with the help of video / karaoke and an active microphone.
With the help of VJ Pro (5 stars!) I'm up to 10,000 video's although I'm a little exhausted by their unlimited subscription plan. I have not download a song in around a week. Note that screens are getting bigger and bigger so 1080p videos are the way to go when possible and are supplied by VJ Pro. Wemix has also been excellent keeping me supplied with UK charts hits. VJ Pro is focused on the USA. VDJ is the best video / DJ software ..so we should be on a winner !

The very nice sports center I did last Saturday night was a little frustrating. The bar had 3 large screen TV's and a ceiling mounted projector with its electric up / down screen. The thing is these are for sport.. yet we want to use this system. I had two TV's with me a 42" and 24" but that was pathetic by comparison. The bar Sky box and its HDMI outpt cable is the way in via a splitter or HDMI matrix. The problem was that the Sky box was mounted very high on the ceiling next to the projector. Anyway without ladders I could not easily get at it so I just used the biggest TV they had via a HDMI cable and my own karaoke monitor both fed by a splitter. It worked well ..but it would have been so much better if I could have got all the screens going.

DJ's ..keep trying to get into the sports TV / projector systems. They are getting bigger by the minute and some are fantastic.

I always try to use every asset I have..video, on screen messages, dancing video things like the Hulk and Spiderman plus the silhouette girls combined with transparency, slide shows, karaoke, vocal work on microphones, me dancing along with the music and so on...almost nothing is off limit. This is the way forward in a competitive world.

Note: I am assuming that you are all competent audio DJ's..this is the first must do !.

Sounds very 70s! There are some cringeworthy videos on YouTube of DJs that have been hired for events and ruined things with their bizarre behaviour. :-)

Ron,
I live in Houston and have been running videos and karaoke across the city since 2005. The problem with most of the bars now is that they do not distribute video, they have a cable box on every TV in the place. Very few places actually have a centralized location that everything runs from. If they did not run cable to every tv in the beginning then it will have to done one way or another. If the place has already run coax out to the TVs then you can find the main line and insert one of these https://www.provideoinstruments.com/HDMI-TO-COAX-Converter_p_92.html?gclid=Cj0KCQiAi57gBRDqARIsABhDSMpiu_8EIGVWodJpb-P0Gzzk4r5MBdwcyCgMuAOObWtAB4-WmldftXMaAtXhEALw_wcB and be able to broadcast to whatever channel you choose and TVs just have to be tuned to that channel.

Hi Partyman,
Your system is different to that of the UK. Most of our venues provide Sky Sport from a single box and satellite dish. This then is fed to a HDMI matrix in big or a splitter in small venues. All we need do is remove the HDMI output cable from the Sky satellite box and then connect to that cable. Our big venues use a HDMI matrix with multiple outputs and channels. So Sky Sport is one channel, then they may have venue offers and deals running on another. In the case of the 10 large screen TV's I mentioned earlier 6 may be on the Sky Sport channel while the other 4 might be promoting drink offers or future events. I use all 10 for video and karaoke via the HDMI matrix and the switches that control the channels. It sounds like were better off because of the central distribution point to feed Sky Sport.

The USA is ahead of Europe in the use of video so in 5-10 years time we might get your system.

Worldwide we need the venues to help us to use their video systems..at the moment sport is King.

That’s your first problem right there......

A “Sports” bar is NOT a “Night club”........

Long time no see.

That's true ..but if we lose all the bars which use screens to display sport there will be precious few venues left for a DJ. We now have super bars in the UK cities..they are big and magnificent.
I've been working for a large US company. They take full advantage of sport..but it is not their first claim to fame. They also put on events of various types. They do classify as a night club with a 4am Saturday night finish plus a lot more.
Its not a simple black and white, positive and negative, nightclub and sports bar thing.
Hm..given that the new super bars are open until 4am in the morning playing music in prime locations in famous city centres I suppose it is incorrect to call them sports bars..what are they?

..anyway whatever they are they may wipe out a lot of traditional nightclubs.

We should stay on topic which I hope is about getting us VDJ's into as many venues as possible using visual elements. That is the way forward for those who use VDJ. We need the hardware to use the fantastic screen / pa set ups in the new super venues.

I should not say too much..but this may be the future venue https://www.liverpoolecho.co.uk/whats-on/food-drink-news/gallery/first-look-inside-einstein-concert-14732782 . How does it compare with London, and the USA? I don't know.
It is even better than the display photos since they dangled an aeroplane from the ceiling and placed a huge screen on the hall far wall plus more.

I may be wrong about things changing..I don't mind if that's the case. All I want to do is learn.

Whatever it is it needs one of us to do the sounds and video !

Note : they do have a set up place for a conventional DJ..you know the stuff. However given the visual hardware they have I think that is insane.
