Abstract
In IMF (Interoperable Master Format), the mastering framework centres around CPL (Composition Playlist) and OPL (Output Profile List) control files. The Composition Playlist references all source media with assembly instructions. The OPL provides the encoding recipe to produce the finished product. This metadata system based on control lists can be leveraged to commercial advantage for highly automated and timely delivery of versions. This paper will illustrate the feasibility of this approach, and practical examples of distribution workflows via file metadata and control list. — Taking the view that the control metadata encapsulated in the CPL is effectively the “version”, the CPL can become the transactional component in a B-2-B supply chain. In this case the “version push” model where self-contained and complete versions of content must be created and distributed by the supplier can evolve to a component pull model where the assets are stored once and myriad versions distributed on demand. In this model, the OPL is the enabling component. The paper will outline the supply chain demands, a workflow design and the architectural components that are required to enable this model. — Security in the exchange of the assets and endpoint verification is an essential component in today's high risk connected environment. If the CPL becomes a transactional component and the customer can pull the files on demand then additional safeguards may be required, so for example upon presentation of the OPL to the content owner for fulfilment, the OPL would be validated by the source rights management system to ensure it accurately represents the contractual rights. — In the proposed model, the content producer retains full control of the master and controls the transcode and format conversion tools used for the delivered version, thus retaining the desired quality levels and including any watermarking desired. Updates can also be delivered in a more controlled fashion with better audit of the distribution than is currently possible. The conversion can be performed on premises or in the cloud, potentially allowing conversion to occur “in flight”.
