I think if a system like this we're developed the screen would be 100% customize able, with simple and advanced views much like RV.

Garmin pretty much has it down

They could have switched on the box's....

Well, will not be long before some smart person figures out how to use these for FPV.

I don't think I saw the reverse challenge to how much FPV experience a certain full scale aviator has when dismissing other FPV enthusiasts' thoughts on a particular subject. I am in the market for an OSD and have narrowed it down to Dragonlink and Eagle tree because they have ladders and additional information that I probably will not care for once the novelty wears off. I fly with a TV but one day may try goggles. I could see how too much stuff coming through goggles that are 640X480 at best (most are less than that) may get cluttered on a screen. One day I hope to have more experience, and don't mind being a noob.

well imho you are better off flying with a large TV for any plane which has a GPS OSD. I do.

Ideally, good to have many different schools of thought working on each aspect of FPV, esp the OSD. Already we see pros and cons to each OSD out there today. Nobody has brought all the pros together into one OSD. And there are new ideas for OSD yet to be introduced.

Personally, I think it would be cool to have a level of customization far beyond what we have today - make it so folks can design their own OSD layout in much more detail than ET and RVOSD do today. Choose fonts, sizes and colours and any graphic, and load your own formulas from the input data in a user friendly 'excel spreadsheet type' desktop GUI.

then there are emerging GCS like displays for a laptop you use beside the FPV TV

Those are both good OSDs but take a look at RVOSD as well. It made me sell all my ET OSD Pro stuff since, for me, it worked sooo much better. Although I know others have had reversed experiences.

hmmm. I might be tempted to do the same. RV is very tempting and ET can be annoying. Only thing is, I like the Eagle Eyes LCD GPS display in case my model goes down far away.

Maybe they simple love to have complete situation awareness. An intermediate solution is the ability to toggle the HUD OFF, so you can use it when needed.
Making a color OSD is possible. However the processing power and complexity of the circuits makes them not practical at this moment, IMHO.
Sorry ElCheapo but I have to totally disagree. Processing power and complexity are no problem at all these days. If you're designing in EaglePCB and can't afford a Multi-thousand dollar IDE - then yes, it is too complex and impractical. The hobby community just doens't have the skill set to do it, and those who do make more money than this hobby could provide on other projects - it's not worth it for us.

It would not be hard to do this at all, I could do it with two IC's and a small ARM chip + a ram chip. The solution requires 3 different voltages to work, and would be a bit bigger than a credit card, but it would be doable very easily.

If i wanted to do it right I'd just use a FPGA. You can even buy video decoder/encoder cores which would do 90% of the work for you for the overlay. These however cost $15k each just to get started (the core, no the fpga) and need double the ram of the discrete solution - however would fit into a much smaller package. This would give you a frame of lag however.

Then there is always Qualcom and TI's DSP ARM Cortex A8s. They have video decoders built in, and someone with enough time can simply program the OSD onto the video picture then send it to the analogue video output. Again, requires 2 powersupplies and RAM, and also provides a single frame of lag. In a 12x12mm package with a 1ghz cortex A8 and a 800mhz DSP there isnt very much you can't do in a small space with a DaVinci processor. You can easily do PIP and multiple video overlay streams with one. At $30 for the chip alone and at least a 6 layer board it's not going to be a cheap OSD to manufacture.

Either way, this is more like 6 months of working evenings on a project, vs for a black and white osd not using a max7456 a week or so (just for the overlay portion.) You'll then need to program in all the nice to have's like return to home, graphics, sensor handling and likely an AHRS system. The return on investment is not really there to make it worth while investing enough time to make this system. If its a labour of love as this seems to be (considering 4 years of development with no release), rather than something developed for sale - it's a totally different story. For those of us making a living from electronics.. its not really worth it.

...That's what I said, possible but not practical. Seems to be too much work for the possible returns.
But I am sure someone will eventually do it . I even remember this guy showing some PCBs here on RCG.

What is so very interesting to me is, most TVs, DVD Players or anything that is connected to a display, has some sort of OSD. I am so very surprised that someone has not hacked these chips, many of them display color.

For not agreeing with him your last line states the same conclusion.

The issue with this is it's the display panel controller or the digital processor. It's not a third party chip which does it.

I read ElCheapo's "However the processing power and complexity of the circuits makes them not practical at this moment, IMHO." as meaning it's too hard to do, not meaning it's impractical to design.

"Too hard" and "impractical" can mean the same thing. Something can be impractical because it would be too hard to do.
Nuf said moving on!

Follow-up question, there has to be some Standard Practice that manufactures share and comply with right?

No, why would there be? Its just an overlay. It's like saying there should be a standard website layout for all manufacturers. Relatively, it's not hard to build, especially if you're spending the sort of money on silicon and development that they do.
