Abstract

The paper deals with software productivity improvement for consumer multimedia devices by means of PC and component technology and shows how this is done for complex real-time content analysis applications used in advanced new storage products of the future. Content analysis is a relatively new and immature technology. It is used for browsing and searching particular content items among thousands of others on “big” embedded storage devices like hard disks. As the storage capacity of hard disk and flash continues to grow rapidly, content analysis is bound to become a key enabling technology in future storage products. A major problem with content analysis features (and many other features as well) is that underlying algorithms are unstable, sometimes unavailable, or at least, very much in their infancy, and as such, subject to frequent changes. The paper describes an approach to facilitate early evaluation and integration of such immature features. This is done by packing each feature, as-is, into components and by providing PC network technology to interconnect them. In our prototyping framework, each component is an independent executable program that runs on some PC in the network, streaming AV data via TCP/IP and being controlled through UPnP networking. Experiences with large-scale prototyping activities we have carried out for the assessment of future content analysis systems, show that a PC based prototyping approach enables the integration of many different media processing features in a short time and that it allows for accurate analysis of the resource (CPU/memory) requirements of such components.
