Almost lost in the sizeable Qualcomm booth in Central Hall of the 2014 International CES show is one of the more interesting demos of the year. Working together, Qualcomm, Elemental, and Akamai are showing a proof of concept of how 4K content can be encoded with HEVC to MPEG-DASH, and streamed to a big screen TV in the home.
The demo shows a vision of the near future using new and emergent technology for 4K streaming, says Kurt Michel, Akamai’s director of product marketing for media.
The video workflow goes like this: Elemental took 4K master files and encoded them at 4K MPEG-DASH using HEVC, outputting 30fps versions at 10-, 15-, and 20Mbps. Those renditions were uploaded to Akamai’s cloud-based storage network, where it’s streamed to the Qualcomm booth. The adaptive video is received by a tablet running Qualcomm’s Snapdragon 805 processor, which supports HEVC decoding in DASH. That image is then mirrored to a big-screen TV.
The Elemental and Akamai parts of the demo are production services available today. The exciting part is how the three players have been brought together to demonstrate HEVC and DASH 4K streaming. It might be a first.
