Abstract: A method is provided in one example and includes receiving media content including timed metadata, generating a common format asset including the timed metadata and a timed metadata index including at least one reference point corresponding to the common format asset. Each reference point includes state context information of the timed metadata at a particular instance of time. The method may further include receiving a request for the timed metadata from a particular client device, and retrieving a determined amount of the timed metadata from the common format asset using the timed metadata index. In a particular example, the determined amount of the timed metadata is an amount sufficient to display a current timed metadata context corresponding to the request.
