In a video processing workflow, an encoder compresses a video stream—taking high-quality video as input, and producing compressed renditions as output while maintaining optimal picture quality. While this is a complicated task when working with pre-recorded video files, for live video it is made even more difficult as the video processing needs to work in real time: The encoder must be powerful enough to produce exactly one second of video every second it runs without fail so that viewers see an uninterrupted video stream, and those video outputs must include all sizes and formats needed to serve the full range of viewing devices. This is technically challenging, and requires a flexible encoding solution that can keep pace with the breadth and depth of today’s video requirements.
When live video encoding needs to be done on-premises, such as when processing baseband SDI video sources, AWS Elemental Live efficiently formats live video for delivery to broadcast televisions and streaming to internet-connected devices. It processes video streams in real time, taking a live video source and compressing it into multiple versions for distribution to viewers. Deployed on-premises as appliances or as AWS-licensed software on your infrastructure, AWS Elemental Live integrates seamlessly into an end-to-end real-time video delivery workflow. Through easy-to-update software, AWS Elemental Live lets you keep delivering high-quality video with the latest features and standards as screens and devices change.
How it Works
Customer Use Case
ITV is an integrated broadcaster and commercial television network in the UK. AWS Elemental Live appliances are deployed in ITV playout centers, encoding high-quality streams to data centers where ITV online services originate. AWS Elemental Live encodes video into multicast streams for online and connected devices prior to content delivery. Streams for syndication partners are created and delivered at the same point in the workflow.
Deploy anywhere, deliver everywhere
AWS Elemental Live helps you deliver content from studio or remote facilities to subscribers on a global scale, or directly to AWS Elemental Media Services, including AWS Elemental MediaConnect, AWS Elemental MediaLive, and AWS Elemental MediaPackage for processing, packaging, or origin storage. Simply connect AWS Elemental Live directly to your cameras to capture and process live inputs as the first step in delivering linear, multiscreen, or live-to-VOD content.
Deliver great quality
Built-in quality-defined variable bitrate control (QVBR) automatically adjusts encoding to the level of complexity within each video frame, optimizing video quality and reducing stream bandwidth. Graphic overlays add a professional look-and-feel to video streams, and easy-to-apply motion graphics enhance viewing experiences.
Easily update video workflows and build new services with advanced support for 4K UHD, HDR, and graphical overlays. Keep ahead of new and emerging industry standards for input and output formats and stay ready to deliver outstanding experiences to new screens and devices. Take advantage of easy-to-update software to keep pace with industry standards so you can continue to deliver high-quality video as screens and devices evolve.
Simplify encoder management
You can control AWS Elemental Live via web interface or REST/XML APIs for easy integration in an appliance, cloud-based, or virtualized deployment. Or, manage multiple encoders as a cluster with AWS Elemental Conductor, an on-premises solution for managing live video workflows.
