If you compile all the white board videos in one big playlist, I'd binge watch'em all. Again. These videos are the reason and my first tools into this hobby. Thanks, maestro.

Great video Bruce! I've missed your tech talks! Thank you for the time and effort that went into this, fascinating to learn more about these systems .

Sign of a great tutor. Straight forward excellent overview. Brilliant

Bruce, you might be able to answer this question about analog resolution. Now the term standard def is from the TV (625 TV lines) in fact there is also standard for Analog HD (1280 TV Lines) which was around in the early days of HD tv's. A typical FPV camera that say its 1000 lines and is a 4:3 sensor does that mean the camera has a resolution of 1000x750 and the 1000x750 picture is been transmitted back to your goggles. So in effect if your FPV camera has a 1200 TV Lines sensor then what you would see in the goggles would be near to the resolution of a 720p HD, 1200x900 (4:3) or 1200x675 (16:19) a analogue system is not bothered about how many lines are fed to it.

You let the best part at the end, those examples of interference and multi pathing on DVR, really help me understand and diagnose my video issues.

That’s a really good summary. Introducing my kids to the hobby and this explains key concepts in an engaging way, and should help them better understand what they are seeing when they fly.

thank you, it means a lot to newbies the tablet's totally fine. you can copy and paste any image you want to show onto the whiteboard and draw diagrams directly on it

Awesome. This is the thing you should do for the next generation. Everyone can do review the toys but only few like you can make educational video like this.

Thank you, thank you, thank you! This is THE BEST explanation regarding ANALOG TRANSMISSION AND RECEPTION ON THE INTERNET. Thank you sir! I stand by my decision to invest in an analog system, and THIS VIDEO is why. Digital is amazing, but it is in its infancy still.

When ever you do these sorts of videos, I already understand most of it, however I find them so relaxing and enjoyable to watch!! Love it!

Bruce I LOVE your videos..The RC Community would be at a huge disadvantage without you in it....You sir, are awsome...HUGE THUMBS UP

Another outstanding video. As usual Bruce you hit it out of the ball park [again] with this one. So looking forward to the next two educational videos. Keep up the excellent work. Greetings from Florida USA

I lost it at the bit about the moon being beyond visual line of sight and being illegal to fly to. Great vid Bruce! The digital whiteboard seems to be working well.

An excellent course of Lectures on Radio Engineering!)) It seems like I remembered the institute !! About the quality of analog television. After all, then they were also engaged in the development of high-definition systems, but it turned out to be a dead-end direction. Best regards, Andrey Sokolov.

Can I get that drawing on a shirt please :)

Bruce: Your new white board works GREAT! Excellent contrast, sharpness, and the author has really preconceived his presentation so well it all fits on the screen as if it was done by a production company! Kudos! More! More! More! - Jim

Great presentation. I’m fan of your way of making explanation throughout the graphic set. Cool, thanks for sharing

Thanks Bruce. That removed a few cob-webs from my 1980 Navy Radio Apprenticeship course. Enough information to be understood and not too much to create confusion for RC modellers. Love the White Board Pad over the Physical White Board.

Michelson & Morley want a quiet word with you , regarding the Aether Must have been sniffing the Ether , to mention the aether :-) Good vid .

I actually enjoy watching these kinds of technical videos which let me learn about radio and EE technology xD Many thanks!

Good stuff Bruce, this is what you do best. :) I read a lot of post with kids re-flashing BetaFlight because they can't bind their Rx, fitting heavy CP antennas to their TinyHawks to increase range; there's a need for basic explanations of how stuff works.

Always impressed with your knowledge Bruce. Thanks. Digital white board does just fine.

You say it simple and easy. I say it's magic. And to think, just a short time ago vacuum tubes were everywhere. I still have a TV with vacuum tubes in my workshop. Thank you Bruce.

Love it, And yes put on a T-shirt, can,t wait for your tec video on the dji digital system

best line of all: "gracefull degredation" 6:24 - that picture looks like "Bernd, the bread" a german kids tv series and figure with educational background ... Whiteboard has worked great for me !

I like this white board replacement, very nice and legible. You can write, mark up, doodle, or whatever without ever getting in anyone's way. Guessing also save if you wish? That was an excellent presentation, especially with the examples at the end. When you have all three posted the uneducated user will be able to make an informed decision, not one based on someone else's bias.

Thank you for the video. A follow-up video showing how to pick the right stuff and how to hook things up in a custom built model would be neat!

I prefer this method of presentation. No squeaky sound or pounding of marker against board. Strokes are consistent without fading ink. The presenter doesn't block parts of the board. It also reminds me of college overhead projector presentations in dark classrooms sitting next to a nice sheila.

Great comprehensive explanation about the matter! Only thing I have to add is the rapidfire explanation talks about antenna diversity (where you switch for the stronger received signal) as opposed to receiver diversity (switching for the better image). additionally rapidfire like clearview and others do some post processing on the output image itself too combining both received images in a clever way If I'm not mistaken

Exellent explanation, thank you Bruce.

I've got to say, the Foxeer Trex camera is so good that I am no longer in a hurry to go digital. When I think at how far analog has come in the last few years, it makes me wonder how much better it will be in another few years. I hope it will be at least twice as good as it is today in a few years.

Yes! love these kinds of videos, please keep them coming!

Great Presentation But i do miss the facial expressions, have to do a talking head down in the corner lol.

thank you, that was very useful. looking forward to your other presentations. I have recently played with putting fpv on my model rc cars, now I know the poor image quality at times was multi pathing. who knew. again thanks, now I know how to get a handle on that.

Thank you so much, nice to have a hobby that helps with school lol You are one of the reasons I love physics and won't deselect it in my next grade

❤Thank YOU FOR VIDEO, COMPLETEY NEW TO FPV QUADCOPTER, REALLY APRICIATE IT

Thank you very much for a great clear explanation. I look forward to the videos on the other systems to finally understand how they all work and compare.

Very clear and I liked the comment about Mars and distance. Thanks.

You are a saint for publishing this.

This is super informative and I really love these videos! Thank you!

I don't even own one of these drones, still I really enjoyed the explanation of how this cool system works. Thank you

Well, I can truly say I've been to school today. I must say, I did learn a few things. Well done Bruce

Thanks, at last I know how it works,, a really good video to watch and understand.

Thoroughly enjoyed that mate, relaxing and informative. Cheers

Good Info as always...✌🏼 Next up.. Bruce explains Fission vs Fusion...👍

I guess you're the first one to call snow in the video graceful 😁

Was just wondering this a few days ago - awesome video, thanks. I really like your explanations.

Excellent. Even a dummy like me understands most of it. Just wish there was a real white board with Bruce in the video.

Excellent presentation and explantion . Thankyou for uploading and that video at the end was a great ending .

The tablet white boards never look as good. Try cleaning with 80% window cleaner and 20% OF 50% OR LESS isopropyl. Always use a soft cloth, if you can do final sanding, it's too rough. Nice review and covered all 5he aspects I have been looking into with the exception of used VR goggles, but that is well beyond what anyone else would look into. 👍👍👍

Nice summary, thanks.

Very clear. Thanks. No snow in your explanations. So I suppose you are digital. 😃 There is one thing I don't understand. Why is analog video stuck to the PAL or SECAM low definitions. Why didn't the FPV video industry come up with another standard ? With a higher definition ?

Great presentation! I like the new white board. I'm looking forward to your videos on digital fpv. If we can use a digital 2.4ghz cotrol signal to fly with dozens of others then why can't we use a 5.8 ghz digital video signal to do the same?

Brilliant tutorial, thanks

Excellent explanatory video:-)

very nicelly done, thanks! good luck!

Hi is the video for digital already planned or is there a "release date"? Really looking forward to it please don't let us hang lol, thank you for your amazing videos!

Great class Sir!

Fantastic video, Bruce! Thanks a lot! 😃 Stay safe there with your family! 🖖😊

Great explanation

I'm sure you're working on it but I'm really excited to see your breakdown of the differences between DJI and Sharkbyte. Can we expect them soon?

Great video Bruce, very clear explanation and I love the digital white board. One thing I think you may have overlooked in terms of latency is the fact that the 4 components the image is passed through (camera, VTX, VRX and then screen) are not in sync with each other. The image data passed between each component has to wait for the next cycle before the data is passed. Wouldn't this mean every time you plug in you will get a different latency depending on how close the component clocks are running? I have found another source of latency can occur when trying to record latency from a moment in time to the screen, because of the time between the event (led light turning on for example) and the camera shutter. This subject has been bugging me for ages and would love to hear you opinions.

Excellent stuff! Now I'm wondering, how can I improve the purity of my aether?

Great educational video keep it up

Looking forward to the rest of the series

Thanks for doing more tech videos. This patreon supporter approves.

Great video. Liked the digital canvas. What camera and vtx are you using in the end shots Bruce?

Thanks again, Bruce - instructive as always. I'd second the 'combined playlist'! The new 'whiteboard' works a treat. Have you got a sheet of paper with the diagram on it, on top of the digi tablet? Else how did it all fit so nicely! Enjoy(?) the influx of us Aussies with our new mutual CoVid Bubble today. Thanks again.

My ideal would be a hybrid analogue digital system. Broadcast in Analogue but a digital circuit also to clean it up and or boost resolution. Im sure its possible just its not been done

Outstanding presentation, and your white board diagrams were great too! Really helped me to understand the basic system of analog video. Could you provide an explanation of how the resolution of the camera does or does not affect the delivered resolution of in the goggles? For example if my camera has a resolution of 800x600 pixels but my display system has a max resolution of 1024x720 pixels, what will the image resolution be in the display system? OR if the camera has a resolution of 1000x720, but my display system (binocular goggle or LCD) only has a max resoultion of 800x600, what will the image be rendered to and how does that happen? Will the camera image simply be cropped to 800x600? You may need to make a separate video to address this, but I have wondered about it forever, but nobody so far has been willing to answer this question. My question has practical relevance when we need to decide how much to spend on our camera for a given, more limited display/recording system. Does the higher resolution camera help get more detail in the display system images or not? You are the best! - Jim

Outstanding! Thanks Bruce :-)👍🎉

This is why analog is still king. Digital be dammed .

Another disadvantage of Analog is that anyone with a analog receiver can see your video by simply scanning the freq band. It's as simple as that.

Thx, very informative and good presentation

👍👍 Great example at the end of the video!

*The pandemic reaches a fever pitch in the northern wilds of Canada* RCModelReviews: Can I offer you a soothing FPV video in these trying times?

Great video

Hi Bruce Great information. But one thing !!! HIGH SCHOOL FLASHBACK !!! LOL ! This one is a great way of explaining what is out there. But I think that you might have missed one. WIFI ! I had started flying quads years ago and I started with a system that used WIFI and it was the worst thing to fly with. I do wish DJI could be more affordable and I could switch over. But until then I will be using Analog. Thanks again for the video and information. And I will be looking forward to the rest.

Perfectly clearly

You should have been my electronics teacher.

Great overview....Thanks...🤔😀🇬🇧🇬🇧🇬🇧

It makes me wonder, why couldn't we use the same technology for higher resolution? Seems like the resolution was arbitrarily picked 50 years ago or so, and could be updated for modern displays

Very useful explanation. Though I have often been confused by camera quoted specifications regarding latency. Think they are either PAL (25) or NTSC (30) frames/sec - or 50/60 if you consider interlaced fields? Taking NTSC, the field to field delay is about 16mS then, sampling at 60Hz per pixel pair. I guess CCD with a global shutter will introduce an extra field's delay compared to a CMOS rolling shutter. So when a camera advertises 'low latency - 6mS' or whatever, what does it mean in reality? Information theory shows that when you get towards a frequency of 1/2 the sampling rate, things go seriously wrong due to aliasing, so it seems to me that quoting such low delays is a bit misleading? Furthermore, where would extra latency/delay between cameras come from - presumably only by low pass filtering the signal (each pixel) over past samples to reduce noise. But, that costs silicon so it seems likely the cheapest cameras are likely to do less of that. So, when they quote latencies of 6mS or so, are they really quoting the time constant of any per pixel filtering, which is completely separate to the field rate, and if so, does it really mean anything?

Thank You!

If you call 60 degrees cold lol. I get it though. I lived in key west Florida years then moved north so totally understand

Great video thank u.

The digital whiteboard is fine. Bit it would be nice to also see your “talking head” somewhere. What I don’t understand is the wifi disturbance you talked about. The wifi router is on the same frequency, so why isn’t the FPB image not completely blown away when are close to your wifi router? Does the VRX “recognize” the FPV image in some way?

When do you expect to continue that mini series cause I have watched it and watched it now again cause I am on the edge of moving "back" from DJI goggles, but that very second edition called Goggles Racing edition that had been released for Mavic 2 Pro as a successor of the first goggles, the white ones. Those red ones came out before the FPV goggles appeared and these red one support the dji digital system and its air unit as the analog world too. I had gotten that for Mavic 2 use but when Ian had unveiled and explained the possibilities of those regarding FPV I went back and purchased analog video transmission that came along with ZOHD copilot as a kit for Mini talon Evo or what it was called. So far so good but I do not want to trust DJI and its decisions about depreciating the current FPV goggles by stopping support or not cause I have been in that spot once and I am quite happy to use those red goggles for analog too since they stopped to sell air units for the red goggles and prices for those used air units have exploded. So I had been lucky to still use those and of cause of the value increase since the goggles itself also gained value on the used market too. Long story short: I am keen to build my own system since I watched a really great and indepth interview on ItsBlunty with the creator and inventor Davice from the open BLUE HD system earlier this year. kzfaq.info/get/bejne/gd6hhpCG3p2agX0.html And I am thinking to go on or start with OPEN HD cause it is supporting a full OSD and iNAV incl. expressLRS on an affordable platform that runs a camera with a powerfull 3b mini "pi clone" (which equals a Pi 3B but of the size and weight of a ZERO). That has been covered partly by mario here in a long distance fpv scenario kzfaq.info/get/bejne/btuYmcukvNTMcnk.html He has done a lot of stuff also on the inav fixed wing group site but I wanted to understand a bit more in general before I start buying stuff for an upcoming winter project. And I guess you can judge the best how it fits among these systems cause I do not wanna rely again on dji's fate or business decisions anymore even though I like their products in general from the point of convenience as a dji drone pilot and plane tinkerer, but not as a drone builder which I never had done. thanks Bruce

Great video i have learned a lot.. keep them coming. Fpv beginner.

Very interesting

I hope you do more tech time videos. Thanks!

Love the new whiteboard. ADSB soon?

I wonder if they will ever get a phased array FPV receiver...

Question: How does a high versus low resolution camera affect the resolution & quality of an image either viewed or recorded by a goggle/VCR in an analog signal system?

Brilliant

Enjoyed very much...wasn't thinking of FPV as a whole, good to know theory's and applications. My FPV Quadcopter uses 5G so one can use either Android or iPhone, or similar to view FPV.... It actually uses 4G LTE Band B12(700 AC)...? Since 5G is NOT available in the USA yet or if so it's only in Larger Cities.....? =)

It looks like bot grinders logo lol the little picture you drew in the left-hand corner

Thank you for the videos, another great one. Learning a lot from you (: Was wondering if when you're doing the DJI one, you could explain the differences between it the Shark Byte, and what's make it so superior (or the Shark Byte inferior).

What are necessary for long range fpv videos and good video on long range

What DVR are you using? It's so clear!!
