Industry Forum to promote Versatile Video Coding

Video is the single most important data traffic driver in mobile networks. According to the latest Ericsson Mobility report it is forecast to grow by 45 percent annually to account for 73 percent of all mobile data traffic in 2023. This is why video compression is key to Ericsson and a great motivation for our research team contributing to the emerging Versatile Video Coding (VVC) standard in the Moving Picture Experts Group (MPEG).

Accelerating the integration of audio codecs

This year, our Software Engineering student Philip got the chance to travel north to join the Ericsson Research internship program. Here he is learning more about audio coding in a project aimed at integrating new audio codecs into different platforms.

Students from many different fields join Ericsson Research for internships or thesis work. You could be next. Follow our blog to learn about the students at Ericsson Research this summer.

5G and eye-tracking enabling mobile VR

How do we cope with the anticipated huge demands on bandwidth and device computational power coming from high-quality virtual reality as video resolutions grow higher and higher? Researchers from Ericsson Research, the Royal Institute of Technology KTH, Stockholm, Sweden, and Tobii have demonstrated how bandwidth and device computational requirements can be dramatically reduced by using smart eye-tracking combined with low-latency 5G networks and distributed cloud. This allows network service providers to provide excellent experiences at a fraction of the network burden.

High Dynamic Range broadcasting

Watching TV is a natural part of our lives. Since the first TV sets made their way into our living rooms several decades ago, the TV experience has gone through several steps of evolution: from black-and-white to color TV, from analog to digital, and recently an increase in resolution from standard definition to high definition and then even further to 4K (a.k.a. Ultra-HD).

The next big thing is High Dynamic Range, HDR.

HEVC codec family growing

The video coding standard HEVC (High Efficiency Video Coding), was made a formal standard last year. It provides the same visual quality with 50% lower bitrate, compared to the previous standard H.264/AVC. This year, media companies are busy implementing HEVC. But of course research and development doesn’t stop there!
