The time base corrector data of the Japanese patent document public access database was just contacted by Mr. Lin (RD-4 ROOM), a motherboard engineer in ASUS, Taiwan. He said that he will be at work with the graphic division staff tomorrow to discuss whether to decide to add TBC and graphics correction functions on the ROG motherboard. Just confirmed. Mr. Lin from the Main Board Division.
ASUS motherboard development and graphics cards are not a team, but they will negotiate because some integrated graphics motherboards are ASUS RD-ROOM-4. In fact, the ROG top motherboards we use are all designed by Mr. Lin and I don't know. We had a friendly and friendly conversation. He asked me if the best solution for VCR graphics processing is SONY? I clearly answered Panasonic. He said that he would contact Panasonic. But I think if it helps me to achieve NTSC to PAL capture mod is very simple, I mainly asked him to transplant the DV camera TBC to the VCR, he said that we need to study before answering. He is not familiar with it now. In all respects, their attitude and professionalism are much better than Japanese IODATA. I firmly believe that the strongest PCB design and manufacturing technology is in Taiwan, China.

Seem this is very important to you so why you not go for sufficiently high oversampled (54MHz or more) video acquisition (8 bit ADC should be OK) and remain processing performed on software side (so synchronization, chroma processing but also accurate TBC) - with around 18.5ns resolution you should be able to get very high quality. Nice example of such approach is https://github.com/happycube/ld-decode.
Something like https://www.aliexpress.com/item/2016-NEW-HANTEK-6074BC-PC-based-USB-Oscilloscope-4-cha...ceBeautifyAB=0 only equipped with USB3 - single channel is sufficient - no need for more channels. Focus on software - this should be way easier than creating TBC from scratch .
Look at this: http://www.techmind.org/vd/paldec.html http://www.rtl-sdr.ru/page/no-title-2 - modern computers can deal with all processing in software.
In the U.S., back in the early to mid 90's, JVC made the best VHS - SVHS playback systems. We're talking 7,500.00 dollar professional decks. Panasonic's Professional decks from the 90's seemed to produce a softer image.
JVC's advice is: If you use AG7750 to record tapes, you'd better use AG7750 to play, so the tracking problem is minimal. The JVC headquarters capture still retains a full range of model recorders.
JVC Japan now officially provides capture services at a low price. At the same time, Fujifilm Japan also offers a copy or digital copy of the movie. Their equipment is very rich, but the technology and effect are general.
JVC's advice is: If you use AG7750 to record tapes, you'd better use AG7750 to play, so the tracking problem is minimal. The JVC headquarters capture still retains a full range of model recorders. The S-VHS machines I reserved are: JVC BR 525.BR 822; AG 4700, AG 7750, AG 8700, AG 7350, JVC HR 20000. Professional VCR One is powerful editing and special effects, one is clear recording effect. There is also an emphasis on perfection and the latter is very rare. This is something many players do not know.
Affected by the geographical environment of the country, most rookies in China think that the AG8700 is a good machine. Actually, this machine is generally a recording machine, not a player. The same applies to the JVC BR 822 and BR 525. In fact, the performance of broadcast-grade equipment is far inferior to that of the AG4700 and JVC HR 20000 (they were all machines that were born in 1994 and have been gradually improved in design).
I think that most of JVC's machines are selling more and more, and there is no machine for durability. Panasonic is the opposite. And Panasonic features jelly color, and jet light, JVC is always the feeling of DNR.
In addition, the best machines discussed by your English players and Japanese, such as the JVC HR 9800 (the machine was sold in Japan in 1989), are not new machines. NV HS 850 is also the same. In 1991, there was production in the Japanese market. Hahahahahaha, I learned a lot from your forum. I can now graduate and publish something for everyone. Thank you
