Widevine DRM: What is it and what version does my phone support?


You've probably heard of Widevine certifications. We'll be discussing DRM, what Widevine certifications mean, and how to find out which Widevine number your phone supports.

What's DRM?

Digital Rights Management, also known as DRM, is a service that streaming services such as Netflix and Disney+ use to prevent their content being copied or distributed without a license. Widevine is used on the internet and Android. Fairplay is used on Safari and Apple devices. Today we'll be discussing Widevine DRM certifications. PlayReady is also available and is used by many set top boxes and Windows.

Widevine DRM

Many streaming platforms, including Netflix, HBO, Disney+ and Prime Video, use Widevine DRM, such as Hulu, Hulu Plus, Hulu, Hulu, Hulu Plus, Hulu, Hulu, Hulu, Hulu, Hulu, Hulu, Hulu, Hulu and Sling. There are three levels of security for Widevine DRM: Widevine, Widevine, and Widevine.

Widevine: This certification is the most basic, and consists entirely of software-based DRM. Widevine L3 devices will play the content at 480p. L3 means that there is no Trusted Execution Environment for DRM encryption (TEE).

Widevine: This is the second level of Widevine L2. It includes either separate video hardware or software-based video processing. Widevine L2 devices will often produce a higher resolution output than Widevine L3, but at a lower quality.

Widevine: In devices that support L1, Widevine L1 protects the highest level of DRM. Video encryption and processing takes place entirely in the Trusted Execution Environment. Widevine L1 devices can play video at the highest resolution.

Which Widevine version is your phone compatible with?

You can find out which version of Widevine DRM your phone supports to determine if your streaming is at its best. You should also know that sometimes your Widevine certification can be dropped to L1 due to poor software updates and third-party custom firmware. It is important to learn how to determine your phone's certification in these situations.

You can check the certification of your Android device with many apps that allow you to see inside your device's hardware.

The DevCheck app is one such tool. It is available as a free download from the Google Google Play Store. After the app is installed, users can open it, grant it the necessary permissions and then go to the "System" section of the app. Users will find their security level under the "Widevine" subsection.

Vodafone Idea claims a peak speed of 3.7Gbps for its new mmWave5G trial


Vodafone Idea (Vi), claimed that it had reached a peak 5G data rate of 3.7Gbps using the mmWave spectrum bands in a recent test in Pune, Maharashtra. Peak download speeds up to 1.5Gbps were achieved in Pune and Gandhinagar's 3.5Ghz 5G trial network.

Vodafone Idea's announcement comes less than one month after Airtel made public its success in cloud gaming sessions using a smartphone running Asphalt 9: Legends. The game streamers Naman Mathur (better known as Mortal’) and Salman Ahmad (better known as ‘Mamba’ were involved in the test.

Vi announced that it had deployed its 5G trial in Pune city. The company also stated that Vi was allocated 26 GHz spectrum by the DoT and the traditional 3.5GHz spectrum band for trials of 5G network networks.

"We are happy with the speed of 5G trials using the Govt-allocated 5G spectrum bands. We have established a strong 4G network across India that delivers the fastest 4G speeds and has a ready network for 5G. Now, Jagbir Singh, Chief Technology Officer at Vodafone Idea Limited, said that we are testing NextGen 5G technology to deliver a true digital experience for Indian consumers and enterprises.

Vi, one of three Indian telcos majors, will compete against Airtel and Reliance Jio for India's first 5G stable network.

The oldest clues to the advent of human clothing in Morocco are found in a Moroccan cave


It is easy to take clothing's existence and necessity for survival as a given. This includes clothes like shirts, pants, dresses, skirts and dresses, and even socks. It all started somewhere.

Scientists said Thursday that artifacts discovered in a Moroccan cave dating back to 120,000 years ago suggest that humans made specialized bone tools and skinned animals before using tools to make fur and leather.

They added that the Contrebandiers Cave items, which are located approximately 800 feet (250m) from Temara's Atlantic coast, may be the oldest known evidence of clothing in the archaeological record.

Our species, Homo Sapiens, was first discovered in Africa more than 300,000. Later, it spread worldwide. Humankind's first clothing invention was a significant milestone in cultural and cognitive evolution.

"We assume that clothing was integral in the expansion of our species to cold habitats," stated Emily Hallett, evolutionary archaeologist at the Max Planck Institute for the Science of Human History (Germany).

Scientists discovered 62 tools made of animal bones. They also found a pattern of cut marks in the bones of three small carnivores - a wildcat, jackal, and fox - which indicated that they were fur-skinned and not meat. Wild cattle bones and antelope bones suggest that these skins may have been used for leather making, while the meat was consumed.

Eleanor Scerri (also of the Max Planck Institute for the Science of Human History) said that clothing is an original human invention. "We wear clothes to keep warm or protect our skin. Scerri said that clothes are also used symbolically to show something about us, and also meet a multitude of social conventions that align with diverse cultures.

Cave artifacts are from a time when personal adornment was common and other signs of symbolic expression were evident at many archaeological sites. The cave did not contain any prehistoric clothing, but fur, leather, and other organic clothing materials that are extremely perishable.

These tools were made in a time when the cave was occupied from roughly 120,000 years ago to approximately 90,000 years back. It is not clear what the clothing they made. Tools with a wide, rounded end are of particular interest, also known as spatulate tools.

"Striations can be seen on spatulate bone tools due to repeated skin contact. The sheen on the ends is due to the use of bone tools against skin. This shape of bone tools is still used to prepare pelts today because they don't pierce skin and are durable. They also remove connecting tissues without causing damage to the pelt." Hallett stated.

The oldest evidence of Homo sapiens clothing is bone needles, which are approximately 45,000 to 40,000 years old and were found in Siberia. Researchers believe that clothing production began thousands of years ago, even though archeological evidence does not support this hypothesis.

Other researchers have also done genetic studies on clothing lice to suggest that clothing originated in Africa around 170,000 years ago. The researchers also believe that Neanderthals made clothing in Eurasia, which is a close human relative who arrived before Homo sapiens. This is based on the cold areas they lived in. The researchers cited evidence that Neanderthals made leather-working bone tools around 50,000 years ago.
