This article demonstrates how to create live linear TV channels from existing video content using AWS Elemental MediaTailor's Channel Assembly feature and a custom Cloud Playout Scheduler (CPS) utility.

• Channel Assembly enables cost-effective live channel creation without expensive encoders or complex playout systems
• CPS utility automates scheduling using XMLTV format electronic program guides (EPG)
• Three-module architecture: UI frontend, backend API layer, and scheduler layer
• Supports manual schedule creation or EPG file uploads for channel programming
• Enables monetization through ad insertion without SCTE marker conditioning
• Reuses existing multi-bitrate HLS or DASH content for live channels
• Deployment uses AWS SAM, requires AWS CLI, Node.js, and GitHub repository access
• Channel creation and management possible within minutes via web interface

CPS provides a serverless, cost-efficient solution for creating temporary or permanent live channels from VOD content, ideal for pop-up channels, e-commerce, and educational platforms.
