* Audio quality may not be up to par for discerning listeners
For anyone out there who's spent a decent amount of money on audio speakers, there's a chance that the hardware inside the Chromecast Audio won't be of high-enough quality for such a purchase to make sense.
As usual, it would be nice for the press to abstain rating the quality of things they have no idea how to evaluate.
I look forward receiving mine, and will try to find a way to actually measure its analog audio quality, also the digital one (mostly: to see if there's re-sampling involved)
Chromecast Audio review: Give your old speakers a new brain
Google’s audio-only Chromecast won’t make sense for everyone, but for a certain kind of customer, it’ll be a no-brainer.
So yeah, why lasers?! You may ask.
A cinema projector is supposed to display intergalactic ships, not shoot them down.
The reason motivating using lasers is driven by the UHD standard and its Rec. 2020 color gamut.
Rec. 2020 colorspace gamut red green and blue primaries are single wavelength colors.
That's how you can render the most intense saturated colors. More intense and saturated than any AMOLED or LCD with Quantum Dots.
Lasers, by nature are this single wavelength light source and thus are just what's needed to render the whole Rec. 2020 gamut when you mix three of them.
Because we're still talking only about making colors by adding variable amounts of 3 primaries, Rec. 2020 gamut doesn't include all colors visible by your eye. For that you would need more than 3 primaries.
It's possible to speculate than Rec. 2020 will be large enough that we might never go further than that by adding more single wavelength primaries and cover even more of the visible light.
But who knows, that might become the next marketing argument at some point 😁
TV manufacturers are also preparing laser backlight LCDs units.
We're not sure yet if they'll reach the public due to power efficiency concerns.
The wide gamut TVs you'll be able to buy, covering not the whole Rec. 2020 gamut but a good portion of them might stay AMOLED or LCDs + Quantum dots.
Between HDR high brightness and full Rec. 2020 support, be sure the future will have everything needed to massage your retinas just right.
IMAX with laser: Superb contrast, 4K resolution, and huge color gamuts | Ars Technica
Ars checks out Europe’s first IMAX laser cinema.
It appears to beat, in compression every other existing lossless image codec in every scenario: wow!
It supports alpha channel, up to 16 bit per channel, is interlaced by default for progressive loading and decoding.
Kind of compression performance to expect:
26% smaller than brute-force crushed PNG files.
35% smaller than typical PNG files.
For lossless, that's huge gains.
FLIF – Free Lossless Image Format
FLIF – Free Lossless Image Format. FLIF is a novel lossless image format which outperforms PNG, lossless WebP, lossless BPG and lossless JPEG2000 in terms of compression ratio. According to the compression experiments we have performed, FLIF files are, on average: …
5X and 6P cameras are indeed based on a large sensor, and choosing this characteristic appear to be indeed legitimately at the expense of OIS.
The IMX377 is a 1/2.3 type: 7.81mm diagonal
In comparison, the Galaxy S6/Edge/Edge+/Note 5, LG G4, is 1/2.6: 6.828 mm (in 16:9)
It's the same sensor diagonal size albeit in 4:3 than the 16:9 1/2.3 type in the Z1 to Z5, which don't have OIS either.

Note: 1/2.3 for 4:3 format is more surface area than 1/2.3 for 16:9 as this metric characterize the diagonal and not the surface area that captures light which evolves at the height x width (aka square)
