Broadcast Systems Characterised By Watermarks TRIZ Cases
- Audio Watermarking with Masked Frequency Codes for Media Tracking
Masked code frequencies embed inaudible identifiers in audio, enabling reliable cross-platform stream tracking and audience measurement.
- Reference Fingerprint Loading Using Selective Watermark Hashing
Selective hashing based on watermark coverage cuts reference storage and computation while preserving accurate media exposure crediting.
- Media Identification Using Watermark Anchors and Signature Windows
Watermark timing and category cues narrow signature matching windows, improving short-ad detection while cutting comparison load.
- Audio Watermark Detection for Unified Media and People Monitoring
A site meter detects both media and people-monitoring watermarks from acoustic signals, cutting separate meter complexity and cost.
