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.
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.
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.
What is statistical multiplexing (statmux)?
Statmux is a technology that allocates bits in real time among multiple live video channels, combining the encoded outputs into a Multi-Program Transport Stream (MPTS). A statmux controller instantaneously adjusts the bitrate of each channel in a statmux pool to make the best use of total available bandwidth. The goal is to maximize network efficiency by optimizing picture quality for a group of channels within a fixed total bandwidth.
What does AWS Elemental Statmux enable?
AWS Elemental Statmux enables broadcasters and content owners to generate content for distribution to headends via traditional broadcast methods. Combined with the advanced video encoding features of AWS Elemental Live, AWS Elemental Statmux extracts more bandwidth capacity from the network. With AWS Elemental Conductor Live managing the statmux workflow, you can achieve reliable 24/7 operations and redundancy.
What is the efficiency gain with AWS Elemental Statmux?
What video codecs are supported?
AWS Elemental Statmux supports MPEG-2, H.264 (AVC), and 10-bit H.265 (HEVC) codecs, at resolutions up to 4K with HDR.
What type of redundancy is supported?
What is the latency with AWS Elemental Statmux?
How do I make changes to my MPTS?
AWS Elemental Conductor Live is the primary interface for MPTS configuration and management. MPTS settings can be edited while an MPTS is running without the need to stop and restart.
Can I change the channel lineup, video pool size, and reserved bitrate for a running pool?
Yes, you can add or delete channels from a statmux pool without introducing discontinuity on the existing channels. You can also change the reserved bandwidth for a pool at any time.
Does AWS Elemental Statmux work with SMPTE 2110 and SMPTE 2022-6 based video inputs?
Can I combine AWS Elemental Statmux with adaptive bitrate (ABR) type workflows in the same cluster?
Yes, AWS Elemental Live fully supports a unified headend architecture where the same source is encoded and used to feed multiple outputs including ABR, constant bitrate (CBR), and statistical multiplex outputs.
