The Realta is used by a few companies including Teranex and Calibre in the UK. It?s a long story. When I was at Snell we developed the first de-interlacer / Scaler chip in the mid 90's in partnership with IBM. IBM in their wisdom packaged it in Gold plated Ceramic so it wasn?t a hot proposition for Consumer. It was used in the Snell & Wilcox Interpolator Gold and several broadcast & industrial processors. Quality was good from the BBC 3 Field Linear filter algorithm, I demonstrated it and its ability to integrate TV and PC raster's to the FCC and a couple of Senators in Washington in the mid 1990's as part of the ATSC effort. Its limitation then was a max resolution of 800 x 600 SVGA which was not a problem as that was where PC's sat. Bar being 8 bit rather than 10 for broadcast its performance was equal to a Broadcast De-interlacer. Snell mostly made custom products for Broadcast and were and still are capable of designing De-interlacers from the ground up. I shared a Technical Emmy for work in this field. The problem today is that there is no scale in Broadcast, Teranex took defence technology from I believe Lockheed Martin, developed it into broadcast products and sold the IP on on for consumer, they now buy it back in the form of Realta. Realta is not easy to use but can give spectacular results. Gennum made a De-interlacer chipset using Snell IP but pulled out of the market when it became obvious that there was almost no margin in selling to consumer and you couldn't charge enough over a few hundred chips with design support in the pro market to make the business worthwhile. So going back to the Realta, Teranex know how to programme it, so does Calibre as they have been using it for years but why would you encourage a bunch of new pro users if they will need extensive design support and only buy a few hundred units. The problem in Broadcast is you get what you pay for, Snell can sell you motion adaptive or fully motion compensated De-Interlacers designed from the ground up by engineers who have been doing it for the best part of 30 years, Calibre and Teranex can sell you product based on the Realta with Teranex algorithms that are 20 years in development, the problem comes if you expect to get good performance from a consumer chip designed from a glossy data sheet. The other factor is that the Consumer companies have been studying this issue for many years as well, some of them have the resource to make their own ASICS and yes some of the ASICS can match the best motion adaptive Broadcast De-interlacers but are not necessarily available on the open market. I bought a Sony 42" HD LCD about five years ago, my choice was based on the fact that it had come tops in the BBC's evaluation and supported direct connection of 1080P50/60 via HDMI. It was not cheap (£2250 list) but has a very competent De-interlacer, I have been told that this model TV has never been matched by the same company as the bean counters have worked their magic on the BOM. So to recap, basically the professional De-interlacer / Up-converter market is not so large so you either use a consumer chip or design from scratch. If you cannot buy the best chips due to volume being too small and you cannot design from scratch then your performance is set by the price you want to charge and the chipsets available.

I thought Teranex developed a product using this chip.
