Ezen az oldalon (ha valaki olyan "figyelmetlen érdeklődő" lenne, mint én szoktam lenni, és nem tekerte lejjebb az oldalt, a tartalomjegyzéke alá, ahol az igazi tartalom van) van egy csomó scaler részletes review -ja:
http://retrogaming.hazard-city.de/Melyek között megtalálható az a scaler is (vagy valami majdnem ugyanaz), mint amire én most várok:
Oh, no! Not another one of those generic, chinese upscaling boxes! I don't like them, you don't like them, so why bother and review another one ? Well, I recently watched a classic game video on Youtube, which was recorded using this particular box and I found the quality to be rather pleasing - at least for a processor of this price range. And since I like new gadgets after all, I quickly ordered one and gave it a shot.
The box in question doesn't get any more generic. I couldn't find any information on a manufacturer and the box appears to be available from different distributors, differently labeled depending on the country where you buy it. The one you see above, saying "HD Video Converter Scart / HDMI" is a version I got from a european eBay seller. In the USA there's a at least one version available which runs under the tag "HDV 8S", so I chose that descriptor for this little review. If you're shopping for this box, just go by the looks. If the converter looks identical (except for the label on top), it should be identical inside. The boxes go for EUR 45-50 over here and maybe US$60 stateside.
The upscaler features a single RGB-enabled Scart input (European layout of course, no matter where you buy the converter from) and a single HDMI output. In addition you get a HDMI input (just for passing through signals) and two audio outputs (digital coax and analogue stereo).
The processor used inside the converter isn't much different from other converters in the same price range - think of the GBS8220 boards for arcade use or the Lenkeng processors. It features a motion- and pixel adaptive deinterlacer that treats all sources as interlaced (doesn't matter if you feed 240p or 480i or the PAL versions of those). For static picture content this results in a nice and vibrant picture, while moving objects or backgrounds get smoothed out and appear heavily interpolated.
All content is scaled to fill the screen, so you get no choice of pillarboxing your content for a proper 4:3 ratio. One trick is to switch the output from a HD resolution (720p and 1080p are available) to a PC resolution (XGA or SXGA). Usually your TV or display will display those in 4:3, even if aspect ratio controls are disabled for other HD resolutions like 1080p. The output resolution can by cycled using one of the three buttons on the side of the box.
So, you basically get ok'ish picture quality (probably very similar to what your TV can achieve on it's own) and you get mediore aspect ratio handling. Is there anything that actually speaks for getting this one ? Indeed the reason is that it just works and is actually what I would call plug'n'play - and that's an extremely rare situation with video processors in general. Other converters I tried suddenly just used composite video from the Scart input, displayed black & white picture or had washed out colors with heavy chroma delay on their HDMI input. Not this one. I got solid RGB colors and sharp graphics from all the classic sources and no hiccups whatsoever.
The output of the converter isn't framelocked to the input, instead you get a 100% perfect 59.94Hz timing with 720p or 1080p output. This might result in a little stutter now and then (when the source is running at a different refresh rate), but it actually makes this converter a perfectly affordable add-on to your HDMI capture box. If you got a live h.264 encoder from Hauppauge, Avermedia or Elgato, you can use this converter to add a RGB-capable Scart input to your capture box. As mentioned earlier, this exact setup is what got me interested in the box. If you want to have a look for yourself, the "Shmup Master" series on Youtube is recorded using this exact converter box. Follow this link for the Youtube video.
Like all converters using this or similar processing, the box adds a little under 2 frames of processing delay to your video chain.

Az EP ugye interlace videó jelet szolgáltat, sosem progresszívet ? Vagy a normál képünk videójele progresszív, és csak az interlész képernyőinké interlace videójel ?
For static picture content this results in a nice and vibrant picture, while moving objects or backgrounds get smoothed out and appear heavily interpolated. Á appám ... ez tényleg úgy hangzik, mint a sima samu TFT monitorom SCART inputja ...
Szóval összegészében várhatóan ez a cucc csak egy pofon lesz kulabának ... annyi előnnyel fog szolgálni, hogy a SCART -os monitorom pocsék képét képes leszek a másik két TFT monitoromon is létrehozni (amelyikeken pedig alapból nincs 15 KHz RGB (SCART) input), ha akarom ... de akarom ? |
