Amlogic S905X5M is an update to the Amlogic S905X4 quad-core Cortex-A55 SoC with a higher 2.5 GHz CPU clock and a new generation Arm G310 CPU that delivers up to close to three times the performance of the Mali-G31 MP2 GPU for more advanced and smoother HDR user interfaces. The S905X5M and S905X4 share the same video decoding capabilities, notably AV1 and H265 up to 4K 75fps, but the new S905X5M drops support for H.265 1080P 60fps video encoding, only keeping H.264 1080P 30fps. One of the new features is the inclusion of an NPU designed specifically for Super Resolution enabling video upscaling with better image quality. You’ll find the differences between the Amlogic S905X5M and S905X5 processors in the comparison table below.

What is AV1
AV1: the next generation of video codecs AV1 is touted to be the new video format for the Internet and is supposed to replace the well-known and proven MPEG format. AV1 codec is a performance-strong and license-free video codec and the brainchild of an alliance between Google’s VP10, Mozilla’s Daala and Cisco’s Thor. Over the last few years, MPEG codes including MPEG1, MPEG2, and MPEG4 variants ASP (DivX/XviD), AVC (H.264) and HEVC (H.265) were the measure of all things when it came to video streaming online. Streaming providers preferred HEVC for their 4K content. But MPEG formats have become the standard for highly compressed video files on DVDs, Blu-rays, and digital television as well. The lack of competition for MPEG formats is not only due to their technological superiority. Many of the algorithms are patented, which has always made it difficult for third-party providers to launch a comparable codec. This affects commercial use of HEVC since streaming providers require a license from MPEG as well as other licensing partners, including individual patent holders. AV1 hopes to avoid these difficulties and, at the same time, provide a technically advanced solution over previous formats. Contents What is AV1 codec? How does AV1 codec work? AV1 codec in comparison to other formats AV1 support How is AV1 codec being used? What is AV1 codec? AV1 is an open source video coding format designed to help businesses and individuals transmit high quality videos more efficiently online. Mozilla, Google, and Cisco are promoting the project to remove existing technological and financial barriers for users. The goal is for all users to gain access to powerful media formats and ultimately use them to exchange and playback video files on their open web platforms – such as the Firefox browser or YouTube. The creators of AV1 codec joined forces as part of the Alliance for Open Media (AOMedia) which has been developing codecs, formats, and technologies for the open web since 2015. AOMedia Video 1 or AV1 in short is the first of its projects to be made available to the public. The open source, license-free AV1 codec is used to compress video files. Encoded files can be saved either as MP4 or MKV. Within WebM, AV1 can be used in conjunction with the audio format Opus to embed HTML5 videos. Why is AV1 important? According to research by […]
What is WiFi 6? New device released…
WHAT IS WI-FI 6? Wi-Fi 6 is the next generation standard in WiFi technology. Wi-Fi 6 also known as “AX WiFi” or “802.11ax WiFi” builds and improves on the current 802.11ac WiFi standard. Wi-Fi 6 was originally built in response to the growing number of devices in the world. If you own a VR device, multiple smart home devices, or simply have a large number of devices in your household, then a Wi-Fi 6 router might just be the best WiFi router for you. In this guide, we’ll go over Wi-Fi 6 routers and break down how they’re faster, increase efficiency, and are better at transferring data than previous generations. HOW FAST IS IT? The short but incomplete answer: 9.6 Gbps. That’s up from 3.5 Gbps on Wi-Fi 5. The real answer: both of those speeds are theoretical maximums that you’re unlikely to ever reach in real-world Wi-Fi use. And even if you could reach those speeds, it’s not clear that you’d need them. The typical download speed in the US is just 72 Mbps, or less than 1 percent of the theoretical maximum speed. But the fact that Wi-Fi 6 has a much higher theoretical speed limit than its predecessor is still important. That 9.6 Gbps doesn’t have to go to a single computer. It can be split up across a whole network of devices. That means more potential speed for each device. For new WiFi 6 android TV box, please check here.
