CableLabs Issues Headend VoD Specs

CableLabs issued the first set of specifications to aid in the creation of next-generation Video-on-Demand (VoD) cable services through the development of headend metadata and content distribution documents. Common metadata specifications are expected to pave the way for new types of VoD application models, such as enhanced VoD, subscription VoD, advertising, and audio services in the cable headend. The newly released specifications build upon a family of specifications that currently are in use.



The ADI2.0 (Asset Distribution Interface) Asset Structure specification defines the logical organization of metadata structures (Group Asset, Metadata Asset, Content Asset) and operations to place content assets in context with one or more cable service offerings. This allows for better utilization of asset management systems at cable headends. Additionally, the specification provides a document message structure containing assets and operations that is transmitted from the content provider to the cable operator to provide initial management and validation of files and structures. XML schema formats are used to provide some of the initial validation mechanisms.



The ADI2.0 (Asset Distribution Interface) Asset Inventory Messages specification is an auxiliary document that defines messages to indicate an upcoming schedule of content distribution or messages meant to help content providers manage existing content distribution processes.



CableLabs developed the specifications working with cable operators, content providers, and hardware component developers operating under a royalty-free Intellectual Property Rights (IPR) pool.
