It’s no secret that a long-term trend in television viewing has been to push resolution to its optimal limits, with
Ultra HD ( 3,840 x 2,160 pixels) and 4K ( 4,096 x 2,160)
becoming the standard. The value of seeing Madonna’s
plastic surgery scars in ever-increasing detail is debatable,
but that’s the way things are headed. However, it isn’t all
about just adding more pixels.
The new buzzword in TV technology is HDR,
meaning high dynamic range, as opposed to today’s
standard dynamic range (SDR). HDR aims to create better
— not more — pixels with greater dynamic brightness and
contrast (sort of like wider dynamic range in audio), plus a
wider spectrum of colors than currently available.
To address the growing list of product offerings in this
market, Media Tek ( www.mediatek.com) recently
introduced the MT5598 chipset for HDR-enabled 4K TVs.
According to the company, “In addition to HDR-enabled content, MT5598 has its own HDR dynamic
range remapping engine. It provides HDR postprocessing
enhancement to SDR content on HDR-capable displays,
re-imbuing color, saturation, and the dynamic range of
brightness that is lost in SDR content. Combined with its
thirteenth-generation picture quality engine, the system
selectively enhances fine details without artifacting,
sharpens edges, and provides 4K motion estimation and
motion compensation (MEMC).”
What is MEMC you ask? Well, it’s defined as a
process used to “eliminate temporal redundancy due to
high correlation between consecutive frames.” I’ll bet
you’re sorry you asked. In any event, a company
spokesman predicted, “Our newest Smart TV chipset will
bring the most advanced online streaming standards and
superior picture quality into homes around the world.” ▲

With the ever-increasing costs (social, professional, and monetary) of getting snagged for DUI, it behooves tipplers to carefully monitor their
consumption of giggle juice. To help in this endeavor, the folks at BACtrack
( www.bactrack.com) have introduced their latest alcohol monitor: the
SKYN, billed as the world’s first wearable tipsiness tracker.
In operation, it measures the alcohol percolating from your skin and
provides a real time estimate of your alcohol level. All you do is strap it onto
you wrist, open the app, and start chugging. The device will notify you
whenever it determines that you are drinking too fast or have reached a
certain BAC level.
BACtrack says the product is aimed at social drinkers, health nuts,
gadget lovers, and young professionals, but it seems perfectly attuned to
chronic boozehounds as well. The SKYN comes in two versions: one stand-alone, and the other integrated with Apple Watch. On the downside, it’s so
lightweight and comfortable that you might forget you’re wearing it and
drive home anyway.
As of this writing, there is still a waiting list to get one, and no price has
been announced. It’s expected to run about $99, which isn’t much more
than an Uber ride home. ▲
