Aspera: Second screen progress in sports

12 September 2014

Aspera, an IBM company, recently teamed up with EVS and Elemental to deploy a system for high-resolution live video streaming via the cloud to enable viewers around the world to watch live HD media and sporting events from their connected devices.

The heart of the workflow — developed for a major client — is EVS’ C-Cast technology that captures video of multiple cameras angles from on-location live production feeds. Embedded Aspera FASP transfer software is used to transfer the video feeds in realtime across continents from sports venues directly to Aspera On Demand server software running in the cloud. The new Aspera Auto-Scale platform manages transfer server instances to meet demand when workloads spike.

Elemental Cloud video processing ingests the mezzanine format, converting it into the multiple bit rates, resolutions and streaming protocols required to serve the range of consumer devices. The final output can be delivered to regional broadcasters and streamed to online viewers.

The complete platform has been proven to deliver hundreds of concurrent video streams transferred over the WAN in realtime directly to cloud infrastructure, according to the participants. “This has been achieved with an effective transfer rate as fast as the live video capture rate at sports venues in spite of heavy round-trip latency and packet loss (over 200 milliseconds and 10 percent peak packet loss over the WAN),” they reported.
