IP video quality of experience (QoE) monitoring firm Witbe has upgraded its core platform to support 4K/Ultra HD.

4KTV was a key buzzword of 2014, and all content providers and broadcasters have demonstrated their willingness to embrace it. But moving on to Ultra HD content involves significant structural changes meaning high deployment costs and technical challenges.

Using the latest HEVC technology, 4K delivery of on-demand content could use a bitrate up to 20Mbps and much more for live content streaming, putting a high stress on the whole delivery architecture. Therefore the performance delivered to the end user will be highly subject to fluctuations across ISPs and video playing device types.

Witbe said that its engineers gave a boost to its robots to support the new generation of 4KTV set-top boxes. They are able to perform lab testing and live monitoring, the company said, to detect conformance issues (black screens, frozen pictures and jerkiness) on 2160p resolution for Ultra HD, without downscaling, through the HDMI output of any 4K set-top box (STB).

"[The robots] are able to perform automated testing of all services: live and on-demand video content (push VOD or streamed VOD) stored locally in the STB's DVR, or hosted in the cloud," the company said. "Witbe's 4KTV solution also provides valuable information on the browsing performance and the end-to-end service availability."
