Διαβαζοντας ενα review για την V20 μονο και μονο για να δω τι λεει για το IFC και τα 600Hz ειδα αυτο :
Intelligent Frame Creation and 600Hz
I normally talk about the picture processing of TVs in one dedicated section of a review, however, because there is so much marketing about these two features, it is probably wise to have a separate area dedicated to each. As the V20 uses exactly the same technology as the VT20, this is what we had to say in the VT20 review:
So first of all we have the Intelligent Frame Creation (IFC) which is a motion compensation technology that interpolates frames. Basically, this means that the TV looks at upcoming frames in the TV show or Film and then guesses what frames should be added in between to make motion look smoother. The positive effect of this is that all 1080 lines of resolution should become visible on screen. However plasma technology, because of its fast response times, doesn’t really have an issue with motion blur like an LCD TV would. Without the IFC function switched on, and using the FPD Benchmark Blu-ray test pattern, we could clearly make out just over 900 lines of resolution on the moving chart. With IFC turned on it made the resolution more stable to 1080 lines, however it also added some artefacts to the image. When moving to real world material, on both TV tuners and Blu-ray, with IFC engaged (it’s called 24p Smooth Film when BDs are played) the image did look smooth but also gave the image a false ‛soap opera’ look. This means that film, which should have a certain look to it, was now presented like it was shot on cheap digital video cameras. This completely robbed the image of what natural motion it should have and I would recommend leaving it switched off. Not only does motion look odd with IFC on for both Film and TV shows but the processing also adds in artefacts where its guessing goes wrong.
Next we have 600Hz and how it is sold to the public as being a motion technology like other manufacturers' 200Hz systems. This is not the case as you have two issues at play here with the Panasonic system. First of all 600Hz (also seen on Samsung and LG plasma TVs) is not the same as 100/200Hz systems. It refers to how the subpixels that make up the plasma image work. It all comes down to the frame rate and how many subfields are used to make up one frame. These subpixels do not directly affect motion but rather make up the image being drawn on screen within each frame. Where Panasonic confuse matters is when this natural way of making images in a plasma panel is introduced to the IFC system and gets called IFC sub field driving. So, with my cynical hat on again for a moment, this 600Hz technology is a marketing department invention to compete with the 200Hz LCD sets, and yet it’s nothing of the kind in practice. So do you need to worry about whether to buy a 600Hz screen or a 200Hz screen? No you don’t as they are completely different beasts altogether. Plasma technology doesn’t really have issues with motion blur like LCD, so the figures in real life use are a non-issue. It’s another big number for marketing departments to use.
Δηλαδη συμφωνει απολυτα με αυτα που σκεφτομαι και προτεινει να ειναι OFF.
Εκει ειναι λοιπον που προσπαθω να καταλαβω, αν ολοι εδω σκιζετε τα ρουχα σας για ενα feature που επρεπε να υπαρχει αλλα μαλλον δεν ειναι τοσο χρησιμο anyway, Η ΚΥΡΙΩΣ ΕΠΕΙΔΗ ΕΙΝΑΙ ΑΠΑΡΑΔΕΚΤΗ Η ΣΥΜΠΕΡΙΦΟΡΑ ΤΗΣ ΕΤΑΙΡΕΙΑΣ?
Αποκει και περα, να πω την αμαρτια μου, στον DLP Προβολεα μου αν και υποστηριζει και αυτος, και στελνω απο HTPC αρα μπορω να στειλω 24p, προτιμω το 60Ηz.... to 24 με κουραζει καπως, μου δινει λιγο εντυπωση flickering και απότι φαινεται δεν ειμαι τοσο ψειρας που να με πειραζει η κινηση στις λιγες οριζοντιες μετατοπισεις που θα εμφανιστουν σε καποια ταινια.
Αρα στην plasma, αν εχει προβλημα με 24p δε με πειραζει τοσο...αλλα αν εχει προβλημα και με τα 60Hz τοτε ειναι θεμα γιατι ολες οι πηγες μου ειναι 60 και ακομα και αν εχουν ρυθμιση για 50 δεν ειανι βολικο να αλλαζω συνεχεια αναλογα αν προβαλω στην Plasma, στον προβολεα ή στο monitor...
