US Patent 11375296 Server-side ad insertions (SSAI) with additional metadata and client functionality

A method of providing customized interaction of a media player based on metadata obtained from an origin server. In one step, the origin server obtains metadata related to an active substream content. The media player is provided a playlist for playing a primary video stream. The playlist includes a request for the metadata, the request being associated with the insertion of the active substream content in the playback of the primary video stream. The origin server receives the request for the metadata from the media player. The origin server inserts the active substream content and metadata segments into the primary video stream. A secondary video stream is obtained after insertion of the active substream content. The origin server provides the metadata to the media player using a metadata storage and a metadata service. The media player customizes the interaction using the metadata during playback of the secondary video stream.
