  "patent_number": "US 12739460",
  "country": "US",
  "title": "How to Automatically Mix Live and Recorded Video for Online Streaming",
  "original_title": "Publishing disparate live media output streams in mixed mode",
  "summary": "This patent describes a system for dynamically creating and updating a playlist for a live media stream that seamlessly combines both real-time video feeds and pre-recorded content based on a schedule and specific triggers.",
  "what_it_does": "The system generates a 'disparate live media output stream manifest,' which acts like a dynamic playlist for a mixed media broadcast. This manifest is built using a 'programming schedule,' an 'additional parameter,' and an initial content source, which can be either a 'live input stream manifest' (for real-time video) or a 'pre-encoded media asset manifest' (for pre-recorded video). Based on a 'first transition' or a 'second transition,' the system inserts new content, whether live or pre-recorded, into this output manifest. It then 'switches' the currently playing media to the newly inserted content and 'modifies' the manifest to reflect this change. For example, a streaming service could schedule a live sports event, then transition to a pre-recorded highlight reel, and then back to a live post-game analysis, all managed automatically by this system.",
  "what_it_does_not_cover": [
    "Does not cover systems that only play pre-recorded content without mixing live streams.",
    "Does not cover systems that only broadcast a single continuous live stream without inserting pre-recorded assets.",
    "Does not cover manual switching between content without a manifest-driven system.",
    "Does not cover systems that do not modify the manifest to reflect content changes.",
    "Does not cover mixing non-media data streams, focusing specifically on 'media output stream'."

  "abstract": "A system generates a disparate live media output stream manifest based on a programming schedule, an additional parameter, and one of a first live input stream manifest or a first pre-encoded media asset manifest. Based on a first transition or a second transition, a different pre-encoded media asset manifest or a different live input stream manifest is inserted to the disparate live media output stream manifest. A first live input stream or a first pre-encoded media asset is switched to a different pre-encoded media asset, or a different live input stream based on the insertion. The first live input stream manifest or the first pre-encoded media asset manifest is modified based on the switching of the first live input stream or the first pre-encoded media asset to the different pre-encoded media asset or the different live input stream.",
