A system is provided for client-side dynamic presentation of programming content in indexed disparate live media output stream. In response to a client request, an updated playback position is presented in at least one of an altered first disparate live media output stream or a generated second disparate live media output stream at a client interface based on an insertion of manifest data and indexed metadata associated with a program identifier. The program identifier is associated with a programming content and is referenced in a published first programming schedule with respect to a playback position in the published first programming schedule. The published first programming schedule comprises a functionality enabled via constraints and rights associated with an indexed first disparate live media output stream.
