Abstract
An input media signal that carries input media content is received. The input media content is used to generate output media content in an output media signal. It is determined whether identification-and-timing (IAT) data is to be authored for the output media content. In response to determining that the output IAT data is to be authored for the output media content, output IAT data is authored for the output media content. At least a part of the output IAT data for at least a part of the output media content is encoded, along with the part of the output media content, into the output media signal. In some example scenarios, this output media signal then contains the IAT data and other related data for synchronization of additional media content with the output media content in content rendering/presentation operations.
