Abstract: Techniques are described for synchronizing video of a live event with separately generated metadata relating to the live event. Timing information representing a delay associated with the encoding and packaging pipeline is determined for each origin that produces a set of content streams, and then provided in the form of a synchronization offset in the client manifest for various streaming technologies. The client device requests the metadata, and synchronizes the metadata with content segments using timing information associated with each and the synchronization offset communicated in the manifest.
