The Present and Future of TV Surveillance

The text discusses how switch-mode power supplies can imprint low-frequency video-related modulation onto household AC mains, enabling potential TV viewing detection via clamp-based current sensing or by querying smart meters (allegedly via GSM/AT command access), and matching these signals against broadcasts. It further alleges that UK TV licensing enforcement explored such techniques and critiques legal processes like the Single Justice Procedure, suggesting risks of false positives and procedural abuse rather than presenting a specific cybersecurity incident.
