    This is not the general philosophical topic that might be implied by the Subject (only so many words can fit).
    Clearly, Sony adds any features that will make the picture look better to Joe Sixpack.
    I'm more interested in specifically what each of these circuits are supposed to be doing and why specifically Sony developed and implemented them.
    Examples are SVM and "Red Push", but there seem to be others as well...
    PS Perhaps we can convince them to make a cheaper model with all this stuff removed? [​IMG]

    You are correct in assuming most of these features are there to make the set look good to the average consumer, and not the videophile or purist.
    The average consumer is using the set primarily to watch regular tv programming on a less-than-perfect cable system, where the picture resolution is noticeably inferior to the dvds and satellite sources we're using. The artificially jacked up sharpness of SVM can actually make such signals look better.
    The typical cable company does little or nothing to insure that color levels and tint are consistent from channel to channel.
    This is one reason ntsc is sometimes called Never Twice the Same Color.
    In the earlier days of color tv, it was necessary to adjust the color and tint every time you changed channels-one channel would have green faces, and the next would be too pink. One of the goals of the mfrs in inventing auto-color and such was to eliminate this need.
    In the mid 60s/early 70s, color tv buyers switching from BW sets put a high priority on not having to twiddle color controls all the time. Remote control was a rare and expensive option in those days.
    Nowadays the average buyer doesn't know how to adjust a color picture.
    The color tv owner of the 60s quickly learned how to adjust the color and tint, contrast and brightness, but it's now almost a lost art without a calibration disc like AVIA or VE.
    Auto color and red push help to minimize color differences when
    changing channels. Red push makes fleshtones pinkish or reddish. Though innacurate, this does make the color appear more uniform from channel to channel, so the average user doesn't have to adjust the picture controls every time they change channels in order to get a halfway watchable picture.
    We now have relatively high resolution sources like dvd that are consistent enough that variances in color intensity, tint, etc. are attributable to the intent of the director and cinematographer, and are ruined by auto-color circuits and red push, and made downright ugly by vsm.
    We need Avia or VE to establish a baseline of correct adjustments in order to make our dvds look as close as possible to what the movie maker intended us to see.
    The ability to turn off the features that make mediocre cable acceptable to the average consumer is becoming more prevalent on higher end sets, which is a good thing. Owners of these sets should remember why these features are there, however, and consider turning 'em back on for casual cable viewing. An accurately set up monitor is essential for dvd, but can make more mundane sources look as truly bad as they really are.

    I prefer not to push the subwoofers until they're properly run in.
