I think Faroudja chips are not so good. At least my Philips
LCD TV has
such chip, and everytime text is scrolling Faroudja's
autosensing goes
This autosensing is not done by the FLI2300, but by Philips circuitry.
Like I already said it can be problem of TV. And to be clear, FLI can be the best deinterlacer hardware for PAL material, but on my environment it has its limitations, and I see that on scrolling news tickers, and it annoys a bit.
But I am wondering, what chip then in TV's make the decision what type of deinterlacer is needed? Most logical place IMO would be deinterlacer chip, because it makes the conversion also. ADC's just dump fields to RAM. Thats why I wrote that Philips should have menu option or similar to make Faroudja to do just PAL deinterlacing with 50Hz.
Normally, the FLI2300 are thought of as the best deinterlacer for stuff like sports etc (video mateial) (vs SI).
doesn't allow this. I see that this is problem of my TV, but if Faroudja was good it would not do this.
So, what scaler/deinterlacer do you have on your proj?
I think it is Pixelworks. But it is projectors backend system feature to control deinterlacer/scaler. It has 3 options, none, video and film. Film is autosense for 24/50 material, video is just 50.
HTPC also can read MPEG streams flags to aid deinterlacing/inverse telecine, and Faroudja's don't have that stuff because they
are behind
video line on TVs/projectors.
This is true, but as long as we do not have CPU´s powerful enougth, hardware solutions will be better.
I tend to use Nvidia's purevideo, which is a bit of both. I hope someday also Linux support is introduced. So vdr-xine a lot of CPU is needed. With Purevideo support all nice features are available on 20% CPU time on 3GHz HT-processor. Just quick meaningless conversion is 100%/2 CPU (how windows sees, as real HT is ~1.3 CPU's) = 50%=1 CPU on 3GHz => 20% on 50% => 1.2GHz processor roughly is needed.
Also, a big problem is that HTPC´s cannot change their refreshrate to the framrate. Which means bad picture quality, unless "burning" video bandwith by going over 85Hz refresh (or prefferebly higher), but who wants that?
Well I adapt my framerates based on content. Because if I see the effort to view my stuff in HD, I can change X & Windows framerates also with much less effort.. :-)
I think automatic refresh-rate adaptation is just video players feature. If modelines are already on X-config file, and tv/projector/monitor has picture optimized for output rate, I cannot see why for example Xine could not automatically change the rate based on input content.
