AWS Elemental Statmux is an on-premises software and appliance solution for processing live video channels using statistical multiplexing (statmux). Statmux is a technology that allocates bits in real time among multiple video channels, combining the encoded outputs into a Multi-Program Transport Stream (MPTS). With AWS Elemental Statmux, you can originate live content and share it with distribution partners for delivery over satellite, cable, or terrestrial networks. AWS Elemental Statmux is deployed alongside AWS Elemental Live encoders, with cluster management using AWS Elemental Conductor Live.

Benefits

High video quality

Maintain high video quality while optimizing for fixed satellite or cable distribution bandwidth. AWS Elemental Statmux rate control provides high-quality predictions for bit rate allocations resulting in better picture quality across channels. You can tune quality settings on a per-channel basis using channel priority, adjusting settings without disruption to ensure that the highest-priority channels maintain the highest quality.

Flexible management

AWS Elemental Statmux can be deployed as a hardware appliance or as software installed on either a VM or bare metal. Management of AWS Elemental Statmux is simple using device clusters administered by AWS Elemental Conductor Live. Statmux is compatible with many conditional access and encryption systems for two stage multiplexing workflows.

Highly available

With AWS Elemental Statmux, several redundancy architectures are supported. You can choose faster redundancy by using 1:1 (active:active configuration) or save on cost by using an N+M (multiple active and multiple spares) mode. AWS Elemental Conductor Live automatically manages the replacement of a failed encoder node, and nodes can be replaced at any time for maintenance.

Increase efficiency

Build on-premises broadcast distribution workloads and deliver more channels using statistical multiplexing of multi-program content for live broadcast video. For content providers who distribute traditional broadcast video along with multiscreen linear video, combining AWS Elemental Statmux with AWS Elemental Live allows you to deliver both in a single architecture.

Improve bandwidth management

AWS Elemental Statmux has automatic bandwidth management to constantly minimize the amount of overhead in the output stream. The multiplex adapts to changes in audio and metadata flows in real time and adjusts the video pool accordingly.

Low latency

AWS Elemental Statmux is optimized for low end-to-end latency, with the option to use additional controls to further reduce latency.
