Statistical Multiplexing (Statmux) is now available with AWS Elemental MediaLive. Statmux is a technology used in live broadcast workflows that allocates bits in real time among multiple live video channels. It instantaneously adjusts the bitrate of each channel in the statmux pool to make the best use of total available bandwidth and combines the encoded outputs into a single transport stream. This maximises network efficiency by optimizing picture quality for a group of channels within a fixed total bandwidth.

Using AWS Elemental MediaLive with Statmux, customers can now deploy linear video processing and playout in the AWS Cloud for broadcast, cable, or terrestrial distribution.

In a press release, AWS Elemental explained: “Media companies, such as national broadcasters, originate live content and simultaneously share that content with their distribution partners. Traditionally, this has been accomplished by preparing channels for distribution using purpose-built, on-premises hardware encoders. These systems can take months to procure and configure, require extensive engineering to operate reliably, and cannot be repurposed once deployed. AWS Elemental MediaLive with Statmux lets broadcasters and content providers build and manage broadcast video workflows on fully managed AWS services and gain flexibility, reduce hardware and management costs, and deliver excellent picture quality with built-in reliability.”
