Telecom carriers have positioned IPTV as one of the key components of triple-play (broadband, television, and voice) or quad-play (with the addition of mobility). Adoption of Web services within a SOA framework as building blocks for developing complex media workflows is an important step toward reuse of media processing tools in an IPTV environment. A Web services approach also provides the capability to abstract network-based services for creation of composite services that can be executed in an IPTV environment. At the same time, adoption of a service bus provides a single point of integration for multiple services, and common features such as service registry and discovery, reliable message delivery, and transformation in a heterogeneous production environment. In this article we present an approach of media enabling the service bus to support offline digital media processes and composite service execution in an IPTV production environment.
