How to sync audio and picture on Apple TV

Published

on

With AirPlay, sharing content with Apple TV is fairly easy and improves the user experience with the Apple ecosystem. Everything becomes even easier when the branded devices can fix problems such as syncing the picture with the sound.

In other words, if you’re using an external networked audio device to connect to your Apple TV and you’re struggling to sync between them, your iPhone can help with calibration. The smartphone is responsible for recognizing the time lag between the image transmission from the smart TV and the sound sent to the Bluetooth speaker.

To continue with the tutorial, it is important to know that the devices must be connected to the same WiFi network, the iPhone must be running on iOS 13 (or newer), and the Apple TV must be up to date.

Here’s how to easily sync the audio and picture from Apple TV to fix broadcast errors.

Sync audio and video on Apple TV on

Step 1: On Apple TV, go to the Settings app and tap Video & Audio.

Step 3: Bring the iPhone closer to the Apple TV and check the notification that appears on the smartphone. Then tap on “Next”. When prompted, enter the passcode to connect your iPhone to Apple TV.

After confirming the task, the TV will play a tone for the iPhone to detect possible transfer errors between video and audio. Make sure the volume is good enough and wait for the process to finish. When done, Apple TV will display a prompt confirming audio calibration with the TV picture.

If you want to repeat the synchronization, you can follow the same steps as above. Although Apple TV notifies you that your TV has already been calibrated previously, you can choose to “Repeat Calibration” or reset the results and adjustments you made.

Material inspired by running shoes can protect buildings from earthquakes

Published

on

By

Researchers at the Queensland University of Technology in Australia have developed a new material that is able to absorb energy and protect buildings from damage from impact. The inspiration came from observing the compound used in running shoes and viscoelastic foam pillows, NASA’s famous pillow.

The 3D printed product has a synetic absorption capacity that can withstand the impact force of a car at a constant speed of 60 km / h. This bioplastic mimics the behavior of auxetic materials – objects that expand transversely when pulled out and contract transversely when squeezed.

“Instead of flattening out when stretched or swelling when compressed, auxetic materials expand or contract in all directions at the same time, making them very energy-absorbing and resilient,” explains materials engineer Tatheer Zahra, first author of the study.

Because auxetic materials available on the market are expensive, the researchers recreated the geometric shapes of these materials with a 3D printer. The resulting product has sufficient strength to replace steel and fiber reinforced polymer networks commonly used in building construction.

A sample of this 3D-printed material weighing just 180 grams can withstand a force of around 2,500 kg in any direction when it shrinks and absorbs an energy of around 260 joules without showing any structural damage or significant changes to the original shape.

“On a normal scale, the connections embedded in these auxetic 3D geometries could theoretically withstand large shocks or impact energies caused by gas explosions, earthquakes, wind forces, and vehicle collisions,” adds Zahra.

Other advantages

Incorporating the new material into conventional mortar, for example, would protect the auxetic geometric shapes from microorganisms and temperatures above 60 ° C, so that they last almost the entire life of a structure without damage.

3D printing also simplifies material modeling and makes it easy to choose the size or design of each part before running an architectural project with various structures with base load and stress requirements that are used in civil engineering.

“Bioplastics offer a more sustainable, low-carbon alternative to fiber-reinforced plastic or other non-biodegradable polymers. In addition, it is more economical than using available auxetic fabrics, which can cost up to US $ 400 (around R $ 2,200 at current price) per square meter, ”concludes Tatheer Zahra.

Humor fans can now mark the agenda: the new season of It’s Cabral’s fault already have an appointment for the journey. The national comedy with Thiago Ventura, Rafael Portugal, Fabiano Cambota, Nando Viana and Rodrigo Marques starts this Monday (25) in Comedy Central in its tenth season with a rhythm of party and celebration.

Because the latest season marks the show’s five-year anniversary. Comedians have been taking part in this roundtable since 2016 with discussions, games and debates that are not always that serious, but always guarantee a good laugh. And to celebrate the special date, the new episodes will receive unprecedented paintings and receive some special guests.

So much so that the opening chapter introduces the singers Marília Mendonça, Maiara and Maraísa, who lead the As Patroas project. So the trio enters the game to tell stories and partake in the dynamic that creates the irreverent and funny style of. shapes It’s Cabral’s fault.

the promise of Comedy Central is that each of the new season’s episodes has the presence of special guests, but it has not been revealed who they will be. But that doesn’t detract from the shine of the quintet, which is still the big star of the program – and especially the turmoil between them.

The tenth season of It’s Cabral’s fault Premiere at Comedy Central next Monday (25th), from 10 p.m.

How much is a burnt Bugatti Chiron worth? You will not believe

Published

on

By

With a value of around 3.96 million US dollars (approx. 21.98 million R $ at current price), the Bugatti Chiron is one of the fastest, most expensive and most sought-after cars in the world. And its price is absurd, even if it suffers an unexpected attack and is ultimately damaged by fire. Like this?

The curious story took place in the US and was reported by the Royal Exotic Cars YouTube channel and just went viral with the purchase and restoration of damaged supercars. The October 9 post already has more than 223,000 views. And why you will understand now.

As Houston and Tony said in a relaxed conversation, the Bugatti Chiron in question belonged to a hip-hop singer and was a victim of vandalism. Three Molotov cocktails were thrown under the hood and the damage to the super machine was considerable.

The body, windows, seats, instrument panel and part of the wiring were affected, a scenario that led to the insurance company that owns the policy ordering the popular “total loss” of the Bugatti. And what does that mean? Simply put, this means that even if someone is willing to spend a fortune buying and renovating the sports car, they cannot drive it and display it. So as the americans would say what’s the point (or, What is the logic ?, in good ole Portuguese).

It’s for sale … and it’s not cheap

Well, despite the little spoiler we informed that the Bugatti will no longer be drivable even if it is repaired, it is for sale on the Copart Insurance website. And the price to get the damaged sports car from the yard to someone else’s garage is incredibly high.

According to the YouTubers, who told the story of the world, the channel tried to make the purchase itself, but was shocked by the amount demanded by the insurer: $ 1.2 million, the equivalent of R $ 6.6 million.

The broadcaster’s idea was to spend about a third of the amount on the purchase, win it back, and resell it with a good profit margin. However, the “plan” failed because of two simple words in the insurer’s final report: total loss. A little happy ending to a very curious story, don’t you think?
