Conversation Awareness will lower the volume and enhance the voices in front of the user, all while reducing background noise.īoth are supported on Apple TV with tvOS 17. Adaptive Audio, a new listening mode that dynamically blends Transparency mode and Active Noise Cancellation together based on the conditions of a user’s environment to deliver the best experience in the moment. Don't mind the low video bitrate as the stream just hasn't reached the high tier yet. Apple TV HD and Apple TV 4K (1st Gen) do not support FaceTime.Ģ pairs of AirPods sharing spatial audio. Only Apple TV 4K (2nd Gen) and Apple TV 4K (3rd Gen). Later this year, video conferencing apps like Webex by Cisco and Zoom will launch on tvOS. The introduction of Split View for Apple TV lets users enjoy watching shows or movies with their loved ones during a SharePlay session while also seeing everyone on the FaceTime call. FaceTime on Apple TV takes advantage of Continuity Camera support to wirelessly connect to the user’s iPhone or iPad, and leverages the device’s camera and microphone to bring participants together on the TV.Ĭenter Stage keeps everyone in the room perfectly framed on the screen, even as they move around, while new gesture-based reactions allow callers to use their hands to generate onscreen effects, such as hearts or fireworks, and add even more fun to the conversation. So maybe one day we could see an American-flag firework for the Fourth of July.ĮDITOR'S NOTE: This video was originally published in July 2019.Apple TV 4K users can take advantage of the new FaceTime app on Apple TV and initiate calls directly from Apple TV, or start calls on iPhone or iPad, and hand them off to Apple TV. Narrator: And even if we never find that brilliant blue, there's still plenty to get excited about on the horizon, like fireworks that burst into different shapes and patterns, even letters. There could be a breakthrough one of these days.
Narrator: But there's still hope for bright blue.Ĭonkling: Certainly it's possible. But it's been a long search, and we're not there yet. Narrator: To be fair, we've gotten close-ish.Ĭonkling: There are some respectable pale blues that are used in special effects, where the audience is closer to the action, where the color is more visible. And even if we do, we'd better hope that it's cheap and non-toxic.Ĭonkling: Arsenic, for example, has been used in some old fireworks formulations, but obviously an arsenic compound is not something you'd want to put up in the smoke where people are watching the fireworks. And even after centuries of searching, we still haven't discovered the right one, nor have we found a more stable replacement for copper chloride. But to make a blue firework, you need copper chloride, which is much more fragile.Īs soon as it gets hot enough to blaze blue, at least 1,000 degrees Fahrenheit, it starts to break down. Strontium chloride, the compound used to make red fireworks, can withstand at least 1,500 degrees Fahrenheit. Because temperatures that are too hot will break down those molecules and wash out the color.īut some molecules are hardier than others. That explosion heats up those color-producing compounds, causing them to glow.Ĭonkling: The hotter you can get the molecules in your flame the more ignition you're going to get, so the brighter and more intense the flame color is going to be. When the fuse burns up it sets off the gunpowder, which explodes. You mix this stuff up into what's called a pellet and then shoot it into the air. You see, to make fireworks, you need four basic components: Fuel, usually gunpowder, a compound that produces color, a fuse, and glue to hold it all together. He's one of the world's leading experts in pyrotechnics, and he says the problem comes down to chemistry. John Conkling: The blue has been very, very difficult to achieve at a level comparable to the greens and reds and whites, just because it's a stability issue at high temperatures.
Pyrotechnicians have tried to produce blue fireworks for centuries, and they have yet to succeed. They flood the sky with brilliant bursts of scarlet, emerald, and ivory. Narrator: Fireworks have been around for millennia. Account icon An icon in the shape of a person's head and shoulders.
