Looking at your pictures of T2 comparing the new transfer to the old is showing a big improvement. I will get this title based on your review.

 Looks like you are making some changes to your cinema, keep us posted on the progress of your screen installation.
93
This will be likely my new Screen build from the V6 XXL Screen Material.

I found some very interesting things about this screen material but this is so hot that I can not  talk about it since I figure out if what cause what I found.
This can take some time.

I still have hope I have this Screen install till Christmas "this year"  :)

Indeed (again) Mark Schubin has presentation(s) that include descriptions of this system used at the 1936 Olympics.

Another little history in English on Fersehen AG http://people.ischool.berkeley.edu/~buckland/television.html

Quote
John Logie Baird began developing the process in 1932, borrowing the idea of Georg Oskar Schubert from his licensees in Germany, where it was demonstrated by Fernseh AG in 1932 and used for broadcasting in 1934.[2] The BBC used Baird's version of the process during the first three months of its then-"high-definition" television service from November 1936 through January 1937,[3] and German television used it during broadcasts of the 1936 Summer Olympics.[4] In both cases, intermediate film cameras alternated with newly introduced direct television cameras.

And for the Telefunke Electronic system (cameraman is Walter Bruch inventor of the PAL-system):

BTW, this site shows that Fersehen AG has also released at least two CRT TVs.

A glimpse is available of both the (front) lens to the and an 30 centimeter CRT set by FernSehen AG.



I did not know there were mechnical Television broadcasts here in Holland as well in pre-war. I just knew about the electronic TV experiments, like radio the decade before backed by Philips. http://www.tvhistory.tv/1935-TV-Netherlands.htm

Wolfgang- it would be great to have a little museum next to your projection room- but I guess your daughter would not like it!
Donaldk- I'm glad you mentioned the Baird "Phonovision" system, it was the first video recording process, long before AMPEX & co. in the 1950s. A British engineer managed to retrieve the images on these first discs - something Baird himself had never been able to do.
Today, the shellac disc of old has been replaced by the compact disc, and the low band video signals of the Baird process can be recorded on a CD-ROM as an uncompressed wave file. The sound for the video can be recorded on the other audio channel.

Mechanical television is by no means dead today. We will get to it!

The years from 1925 to 1939 were a time of feverish development. What had begun with a 30 line system and wooden discs ended here in Germany (just before the World War interrupted everything) with a fully electronic 441 line system including interlace.
The 2 MHz bandwidth of 441 line tv could not be transmitted on shortwave anymore, so TV helped bring in a new era of what we call FM ukw radio today.
But the Nipkow disc was used way into the fully electronic era, mainly for film scanning purposes. Here the inherent light loss of the Nipkow system could be compensated by using arc lights for the scanning process.
This led to one of the craziest inventions: "Zwischenfilmverfahren" in German.
If you wanted to "televise" an outdoor daylight scene, the Nipkow disc was not useable because of its light loss. So the rather incredible idea was

To film a scene on 35 mm movie film,
run this out of the camera into a super fast developing machine ...
then scan the still wet film with a Nipkow disc scanner.

This whole contraption was built into a big truck with a platform on top where the film camera stood on a hollow pedestal. The exposed film would run thru the pedestal into the truck to be developed and scanned ...and bingo! Here was your "Zwischenfilm " - in-between-film- process.
Below is a design for a 441 line Nipkow disk with several spirals and synchronization holes.
The second image shows the last Fernseh AG scanner built before the war - combined film scanner and a system like a videophone for transmitting images of the "talking head" type- 441 lines with a rotating disc in a vacuum housing. 10.000 rpms! If something goes wrong with such a monster, it's "duck and cover!"

In the News / CES 2018: Samsung reported to show 150" MicroLED display for home use
« Last post by DCI forum on Sun November 26, 2017, 06:23:52 PM »
Korean news outlets are reporting that Samsung will launch an 150" MicroLED display for home use. Showing it in Las Vegas at CES that kicks off the year for consumer electronics.

“Samsung will likely push for the micro LED TV in the premium TV segment after releasing them next year”, an industry insider told ZDNet Korea.

According to Korean media including Korean Herald Micro LED TVs have not been widely commercialized so far due to high manufacturing costs and technical difficulties to make a panel with LEDs measuring less than 100 micrometers, which is slimmer than the width of a human hair. Despite the size of the Micro LEDs, there will only be large displays for the near future due to dificulties manufacaturing 4K displays in smaller sizes using the technology. However some media do confound Micro-LED displays and TVs with Samsung's RGB SMD LED Cinema Display, caling that Microled.

Currently micro-led displays are expensive, the most shining example being the Sony CLEDIS/C-LED. There is the expectation that it will in the longer run be less expensive than OLED, or even High-end LCD. Using inorganic materials, over Organic LED, is said to lead to thinner displays and easier manufacturing compared to OLED.

Sony is looking to deploy CLED into cinema's, so may Samsung. Looking to use, in the future, its micro-led displays instead of the first generation Samsung Premier cinema displays, using 2.5mm pitch SMD RGB LED vdieo wall displays.

Panel maker AUO's  CEO, chairman, Paul Peng, expects that Micro-LED to remain stuck in the development phase for the next two years, eventhought there be many prototypes, demonstrators and even engineering samples.

Apple and Samsung are in yet another race to lead the Micro-LED world, Apple reportedly focussed on small Apple Watch/iPhone sized displays, with Taiwanese chipmaker TSMC to address manufacturing problems, and moving R&D states side, completing Taiwanese R&D phase.

Samsung is reported to acquire Taiwanese Micro-LED company PlayNtride.

That trans Atlantic transmission was actually captured on a record, yup phonogram/-graph became a videograph. Low information content made that it could be captured onto a shellac disc. A number of years ago this disc was decoded using modern computer technology.
