Ad-Flow Overview

Ad-Flow is a cloud-native solution designed for automated SCTE-35 marker insertion in live video streams. It specializes in analyzing video content, detecting ad breaks, and inserting precise SCTE-35 markers to enable seamless ad insertion workflows.

Ad-Flow is distributed through the AWS Marketplace

How Ad-Flow Works​

Ad-Flow operates through a sophisticated process that ensures accurate ad detection and marker insertion:

  1. Stream Capture
    Ad-Flow captures incoming live video streams from RTP or SRT sources.

  2. Buffering and Analysis
    The stream is buffered for a configurable duration (roughly 2 minutes) to enable advance analysis of the content.

  3. Ad Break Detection
    During the buffering period, Ad-Flow analyzes the content to identify ad breaks and calculate their precise duration.

  4. SCTE-35 Marker Insertion
    As the buffered stream is re-transmitted, Ad-Flow inserts SCTE-35 markers at the correct positions, including:

    • Accurate start time for each ad break
    • Precise duration of the ad break
    • Repeated markers during the ad break for redundancy
