A metadata generator is configured to generate recorded metadata which is metadata recorded with an AV signal. A classification determinator is configured to determine, upon receipt of the recorded metadata, which playlist a portion of the AV signal corresponding to the recorded metadata is classified into by referring to a classification database storing a classification rule and to output classification information indicating a determination result. A playlist generator is configured to generate a playlist according to the classification information. A recorder is configured to record the AV signal, the recorded metadata, and the playlist on a recording medium."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Signal recording apparatus, camera recorder, and signal processing system","description":"A signal recording apparatus configured to classify video/sound materials is provided with a reduced operational burden.
