The invention relates to a method for identifying sentinel frames in a video. Sentinel frames are key frames within sentinel sequences which signal a transition or boundary between a first type of content and a second type of content. The invention also clusters the sentinel frames into groups having similar characteristics. This enables a dataset to be built up to aid future detection of sentinel frames. The Hearing Officer assessed the alleged contribution in the absence of a complete analysis of novelty and inventive step by the examiner and concluded it did relate to a technical contribution. The application was remitted back to the examiner to complete their examination.
