The Philips-Open TV® Product Family Architecture for Interactive Set-Top Boxes

This paper presents the Philips-OpenTV product family architecture of Philips Digital Networks. The Philips-OpenTV product family consists of several set-top box products that serve different customers and markets. The paper describes how the software architecture achieves considerable hardware and product independence for the different product executions. Among others, this is achieved through separation of concerns, layering and strict interfaces. Some practical examples and experiences are described that illustrate the suitability of the architecture to accommodate change.
