Content aware monitoring of media system output using assertion checks
A recently granted patent (Publication Number: US11871057B2) discloses a method and system for content-aware monitoring of a media system's output. The method involves accessing a media assertion schedule containing assertion checks with conditions and timecodes, receiving observed signature files with processed media frame versions and timestamps, identifying relevant assertion checks, validating conditions using observed signatures, and generating an indication of synchronized output if conditions are met. The system includes a signature generating module and a server processor that access the media assertion schedule, validate conditions, and generate output synchronization indications based on observed signatures.
Furthermore, the method and system involve analyzing media streams, generating expected signatures, and validating assertion checks such as content match and frozen frame checks. The content match assertion check includes expected signatures for media frames within a timecode range, validated by calculating similarity metrics between observed and expected signatures. The frozen frame assertion check involves consecutive video frames, where similarity metrics below a threshold indicate validation. Additionally, the system can generate assertion checks based on media program schedules and metadata, including graphic overlay data analysis to create content match assertion checks for specific video frame portions. Overall, the patent aims to provide a comprehensive solution for monitoring and validating media system outputs in a content-aware manner, ensuring synchronization with expected outputs.
