How EPG Time Markers Work

Precise synchronization between video streams, EPG data, and advertisement insertion points for perfect broadcast timing

What Are Time Markers?

Time markers are precise timestamp annotations that synchronize Electronic Program Guide (EPG) data with actual video stream content. They mark critical points in broadcast media such as program boundaries, advertisement breaks, and content segments.

Our system enables broadcasters to accurately define where programs begin and end, ensuring viewers see correct information at all times.

Program Markers

  • Program start timestamp
  • Program end timestamp
  • Content duration validation
  • EPG metadata synchronization

Advertisement Markers

  • Ad break start point
  • Ad break end point
  • Individual ad boundaries
  • Ad insertion opportunities

Video Stream Synchronization

Precise Begin/End Marking

Our system synchronizes EPG time markers with actual video stream timestamps to ensure frame-accurate alignment. This eliminates the common problem of EPG data being out of sync with broadcast content.

Synchronization Process:

  1. Video stream analyzed for actual content boundaries
  2. EPG schedule data compared against real broadcast timing
  3. Time markers inserted at precise begin/end points
  4. Discrepancies corrected automatically or flagged for review
  5. Validated markers stored with millisecond precision

Stream Format Support

Live Streams

  • HLS (HTTP Live Streaming)
  • MPEG-DASH
  • RTMP streams
  • Broadcast transport streams

VOD Content

  • MP4 files
  • MKV containers
  • Recorded live streams
  • Archive footage

Customer-Controlled Advertisement Markers

Beyond EPG: Full Advertisement Control

IMPORTANT: Our system empowers customers to mark advertisement begin and end points independently from EPG data. This is crucial for monetization and content management.

While EPG data provides program information, advertisement markers give you precise control over ad placement, replacement, and insertion across your entire content library.

Manual Ad Marking

  • Mark ad break start/end in live broadcasts
  • Define individual ad boundaries within breaks
  • Tag ad slots for dynamic insertion
  • Annotate VOD content with ad opportunities

Automated Detection

  • Audio silence detection for ad breaks
  • Black frame identification
  • SCTE-35 marker recognition
  • Machine learning pattern recognition

Use Cases for Advertisement Markers:

Revenue Optimization

Replace outdated ads in VOD with current campaigns

Targeted Advertising

Insert personalized ads based on viewer data

Content Localization

Replace ads for different geographic regions

Ad Skip Prevention

Enforce ad viewing in premium content

Ad Injection Middleware

Dynamic Ad Insertion for VOD & Live Streams

Our advanced middleware technology enables real-time advertisement injection into existing VOD records and live stream content. Using time markers as reference points, ads can be seamlessly inserted without re-encoding the original video.

How Ad Injection Works:

1

Middleware intercepts video stream requests

2

Time markers identify ad insertion points

3

Ad decision engine selects appropriate advertisements

4

Manifest manipulated to include ad segments

5

Seamless playback with inserted ads delivered to viewer

Server-Side Ad Insertion (SSAI)

  • Ad blocker proof - ads part of main stream
  • No buffering between content and ads
  • Unified viewing experience
  • Works across all devices and players

Manifest Manipulation

  • HLS playlist modification on-the-fly
  • DASH MPD dynamic generation
  • Segment URL rewriting
  • Timeline continuity maintained
