The SYMKLOUD system uses the higher performance of the graphics processing unit (GPU) in Intel’s fourth generation ‘Haswell’ Core i7 processor to handle encoding of HEVC H.265 video. This allows distribution of HD video at half the bandwidth of existing video encoding.
Using the GPU frees up the central processor for other media management, local ad insertion and video analytics, says Sven Freudenfeld, business development manager for Kontron’s Communications Business Unit based in Montreal. "Intel has evolved its product line to allow the GPU to do video encoding, and this is primarily for cable and mobile operators," said Freudenfeld. "In the past it took a lot of CPU horsepower and the scalability just wasn’t there."
The current system using the previous Ivybridge processor can handle 144 streams of MPEG2 H.264 video in the 750W power limit. The 2U unit with 18 Haswell processors supports up to 8 simultaneous streams of 1080p HD using HEVC for the same power consumption.
Kontron has worked with Vanguard Video and Vantrix to deliver the system, which is being shown at the IBC show in Amsterdam next week. It is also provisioned for cloud management using OpenStack.
“To date the intricacies of HEVC have required much more processor power than H.264,” said Irena Terterov, Vanguard Video CEO. “However, the harnessing of 4th generation Intel Core technology and Kontron system expertise into the scalable SYMKLOUD platform has shown us the tremendous cost versus performance potential to make HEVC in cloud infrastructure very viable. Clients will possess improved cost controls and power efficiencies, even when faced with wildly fluctuating traffic volumes that require on-demand resources.”
“While HEVC is in an early evolution phase, it will quickly become the de facto codec as the Ultra HD era catches on, driven by both the production and consumer side of the business,” said Jean Mayrand, Vantrix CTO. “We are just scratching the surface of what can be accomplished with cloud-based video delivery, media processing, etc. and are working on how to better support providers to provision all of this in today’s cloud infrastructure for the best overall channel performance per watt.”
