AWS Elemental MediaLive now offers statistical multiplexing

Maximises network efficiency by optimising picture quality for a group of channels within a fixed total bandwidth

AWS Elemental MediaLive is now offering statistical multiplexing (Statmux), a technology used in broadcast workflows that allocates bits in real time among multiple live video channels.

According to AWS, the new technology instantaneously adjusts the bitrate of each channel in the Statmux pool to make the best use of total available bandwidth and combining the encoded outputs into a single transport stream. The company said this maximises network efficiency by optimising picture quality for a group of channels within a fixed total bandwidth.

Key benefits of AWS Elemental MediaLive with Statmux include:

  • Cloud flexibility—add, remove, or update live channels based on evolving audience and business needs, easily introduce new codecs, prioritise resources on a per-channel basis, and take advantage of multiple codecs and resolutions
  • Built-in resiliency—resources are automatically allocated across multiple availability zones for high availability and fully managed failover
  • High video quality—Statmux for MediaLive allows users to maximise video quality while optimising for fixed satellite or cable distribution bandwidth. Users can tune quality settings on a per-channel basis without disruption to assure that the highest-priority channels maintain the highest quality
  • Operational efficiency—build broadcast distribution workloads in minutes, without on-premises hardware, and deliver channels more efficiently over fixed network bandwidth
  • Monitoring and metrics—integrated Amazon CloudWatch monitoring enables real-time views of video metrics and multiplexer performance
  • Unified headend—for content providers that distribute traditional broadcast video as well as multiscreen linear video, Statmux for MediaLive can deliver both through a single architecture. With the increasing importance of OTT delivery, having one system to manage all encoding can dramatically simplify operations
