The HDMI Forum has released the official HDMI 2.1 specifications. The opportunity to see that the standard still has a bright future ahead of it.
HDMI 2.1 unveils itself and lets us see a significant increase in its capabilities. The HDMI Forum explained that it can support resolutions up to 10K (10 240 x 4320p)! It can also display 8K at 60 Hz or 4K at 120 Hz. The standard is of course compatible with the Dynamic HDR, which adapts the various parameters (such as contrast, brightness or colorimetry) of the watched videos live.
Even more impressive, it can handle a bandwidth of up to 48 Gb/s (in contrast to the 18 Gb/s of HDMI 2.0) thanks to an Ultra High Speed HDMI cable that you will need. The latter is itself capable of delivering video in 8K HDR, while protecting devices near electromagnetic interference.
The sound aspect is not to be outdone with the support of eARC, which makes it possible to take advantage of 3D Atmos/DTS: X audio formats. Finally, the VRR mode is aimed directly at gamers because it offers a variable refresh rate, which allows you to enjoy a better fluidity in game and reduce the lagoon. No wonder for people who already know Nvidia’s G-Sync technology.
Given the weak content of the resolutions mentioned above, you will have understood that it is a question of taking the lead here. But the democratization of the 4K is progressing. It is therefore understandable that the flagship standard for home audio-visuals must keep one (sacred) one step ahead.
With Karma, US sports camera manufacturer GoPro wants to compete with Chinese DJI’s Phantom and Mavic. We put it to the test.
Go Pro relaunches its Karma drone gopro. After a reminder of the first version for a recurring battery problem, the American company hopes this time to get back on the right foot and finally enter the race of video drones, where DJI reigns almost as master. We tested it, here’s the verdict.
Stabilization. The three-axis stabilization system fulfills its function perfectly. The image does not move in flight, except for an inertia movement in the event of a sudden stop, which can be easily avoided by smoother steering. Note that the camera is in front of the propellers and that they are never visible in the image. A very good point.
Image quality. The model we tested is equipped with a Go Pro Hero 5 camera, which shoots in 4K at 30 frames per second. It’s accurate with a very interesting color rendering. Full HD mode is less efficient. Also missing is a 60 fps 4K mode, proposed by the Phantom 4 Pro DJI for example.
Security. Go Pro integrates automatic return with two options: return to the starting position or return to the user’s position. Both prove to be accurate. However, we did not have the opportunity to test the drone’s behavior in case of signal loss. The absence of obstacle detection can also be regretted.
The radio control. Nice effort from Go Pro. The radio control, with its roundness, is particularly well thought out, with its integrated screen and its sticks and buttons well positioned. It is very small in size. On the other hand, it is a pity that there are so many reflections under strong light.
The kit with the stabilizer “karma grip”. A good point for Go Pro, the Karma comes with a handle to adapt the camera’s stabilizer for ground shots. This is enough to amortize the price of approximately 1,300 euros when the competition chooses to sell this option separately.
We didn’t like it so much
The weight. With its folding arms, the Karma offers a relatively small footprint, but this advantage is quickly erased by the weight of the machine. Go Pro announces one kilo for the camera, 545 grams for the battery and 230 grams for the stabilizer, i. e. almost 1.8 kg in total, without the camera! When used, it is heavy, too heavy compared to the competition.
Reactivity. Karma is not a racetrack, a race drone. But that does not excuse the drone’s pathetic behavior in the air. In normal mode, the device does not reach 30 km/h and reacts very, very slowly. All this, of course, improves the image stabilization, but that’s less argument for the pleasure of flying. In sport mode, the drone becomes more nervous, with a top speed around 50 km/h, but suffers from a high inertia that affects the image and, above all, battery life.
Autonomy. Let’s talk about the battery! Karma offers just 20 minutes of flight time for one hour of charging. With such a large accumulator (545 g!), we had every reason to hope for something better. The total weight of the machine doesn’t help, that’s a shame.
Few intelligent modes. Go Pro does the strict minimum on this point. Three intelligent modes are available (Panorama, Cable Cam, and Orbit). No “Follow me” mode, therefore, to order the drone to follow its pilot. The modes present are tedious to use, with the need to determine the route before launching the automatic flight.
GoPro’s adventuring into the UAV market has come up against one obstacle: not to be a quadcopter specialist. The defects of Karma only accentuate the sensation of paying high prices for a product that is not fully optimized.
Microsoft hoped to reach 1 billion Windows 10 equipped terminals in 2-3 years. It is currently active on 600 million devices worldwide.
Windows 10 has found its way on 600 million active terminals, said CEO Satya Nadella.
Nadella made this comment at the company’s annual meeting of shareholders on Wednesday, according to GeekWire. Microsoft was not immediately available to confirm the observation.
Goodbye billions of Windows 10
The company’s high hopes are based on the adoption of Windows 10, which has allowed it to move from being the sole software company to becoming a more service-oriented company.
Terry Myerson, vice president of operating systems at Microsoft, had originally set a target of 1 billion terminals within two to three years of the launch of Windows 10 in 2015.
The company finally had to give up this ambition, the fault in particular for the complete failure of its platform in the smartphone sector. Windows 10 must now allow the editor to resist in a world increasingly oriented towards mobile phones.
In comparison, Google claims, for example, more than 2 billion active users for Android. As for Apple, its iPhone has sold more than a billion units since its creation in 2007. Windows is no longer the only platform, and Microsoft has had to rethink its strategy to adopt an approach that includes other OSes.
Snapchat is preparing a significant update with a new interface. It is beginning to show through a few shared captures online.
Snapchat is in a difficult situation. In spite of its community, the company is struggling to break even, and competition has intensified. Worse still, Facebook did not hesitate to pick up on its functions and take over some of its peculiarities.
Evan Spiegel is well aware of the stakes involved and recently announced his intention to deploy a new version of his application at the end of the year.
Snapchat is going to get a new skin.
The latter will benefit from an entirely new interface that is both simpler and – above all – more intuitive. The idea is, of course, to make the tool accessible to the most significant world to revive growth and gain new market share.
Evan Spiegel returned to this new design during a panel discussion by presenting several visuals of this new interface.
The new Snapchat will, therefore, be entirely different from the old one and will require a separation between social content and media to simplify the use of the solution. Evan Spiegel is aware of taking a risk, but he thinks that this separation of materials will allow him to monetize the solution better.
On the one hand, the solution will always allow us to interact with our contacts and groups. On the other hand, it will present the different contents shared by the platform’s users, content displayed on an infinite grid composed of tiles, all with horizontal navigation.
In order not to lose the most frequent users, the application will always open on the camera. Snapchat will, therefore, continue to place creation at the heart of its priorities, and this is apparently a good thing, as it has also contributed to its success.
A more accessible interface to reconnect with success
To access the activity of your friends, the user will just need to scan the left panel. This page will list all the new content shared by the contacts, and it will, of course, be enough to tap on the element of its choice to display the text, image or video associated.
The right panel will show content shared by publishers, media, and the community. The Discover tab will be present, as well as for the Snap Map and the Collective Stories.
The content of this page will vary according to each user, and the tool will rely on the user’s personal preferences to bring up the most relevant elements. On the other hand, all indexed content will be systematically checked by the company’s employees before being published.
This tab will evolve in the coming months to highlight the content created by influencers and creators. The latter should, therefore, gain in visibility.
As a reminder, the new version of Snapchat will start rolling out at the beginning of December, but not everyone will be able to enjoy it at the same time. The company has opted for a progressive deployment.
Apple’s latest smartphone is not the expected revolution, but its facial recognition technology is particularly impressive.
The iPhone X, long awaited by Apple fans, is finally released. For this anniversary smartphone, released just ten years after the first iPhone in 2007, Apple wanted to mark the occasion and promised: “the biggest leap forward since the original iPhone.”
So what is this new smartphone worth: is it different from its predecessors? After a week of hands-on experience, here are the three strong points and three weak points of the iPhone X.
Three reasons to buy it
First good point: design and ergonomics. With the iPhone X, we say goodbye to the iconic design of the iPhone, which has remained virtually unchanged since its inception with its unique round button and large rectangular screen. Apple has chosen to get rid of this physical button so that the screen occupies the entire front face of the phone. Featuring two glass fronts and aluminum contours, the iPhone X looks like a small high-tech gem.
The phone is equipped with a new 5.8-inch screen – the first OLED screen that meets iPhone standards, manufactured by its competitor Samsung. This Super Retina screen displays high-precision, vivid colors, and beautiful contrast.
Previous iPhone users will have to learn new gestures to navigate in the smartphone without the Home button. But ergonomics, which has always been a high point at Apple, is very well thought out and it only takes a few minutes to get used to, for example, getting out of an application by sliding your finger upwards.
Face ID “facial recognition is the great innovation of this phone. The user’s face becomes his password: he just has to look at his screen, and it unlocks almost instantly, or to confirm a purchase with Apple Pay.
Configurable in a few seconds, this function is useful even in the dark, or when a scarf or sunglasses half mask the face. A little extra: as long as the phone detects that its owner is not watching it, it does not display its notifications in their entirety, to preserve its privacy.
Unlike Samsung’s Galaxy S8 facial recognition, which is less reliable because it is based on 2D, the Face ID system projects 30,000 invisible dots on the face of the person, to map it in 3D. It is challenging to hack into this system, even though a Vietnamese cybersecurity company said it was achieved by printing a 3D face.
The test of the iPhone X in video
Three reasons to do without it
Apple’s main selling point, which promises a “big leap forward” and aims to “pave the way for technology for the next decade,” is falling through the cracks. The iPhone X is a beautiful evolution, but not a revolution.
Whereas ten years ago, the apple company defined the essence of the smartphone itself, this new product seems to be more in line with the competition. Its onboard screen can be found on the Galaxy S8 and LG V30.
And augmented reality applications, enhanced portrait mode for photos and induction charging, presented as new features, can be found on the iPhone 8.
