In this paper, a novel multi-target design methodology based on the concepts of transformational design, and its application to the interlaced-to-progressive scan conversion (IPSC) problem, are discussed. Starting from a single high-level behavioral specification in VHDL a direction detector used in IPSC algorithms is mapped onto both a custom(More)
Automatically generated summaries of TV content are indispensable for content selection and navigation in CE-devices. We show two different types of summaries: Short video trailers and visual overviews consisting of representative frames. The demo does not only show the feasibility of the proposed algorithms, but also shows how different types of generated(More)
Achieving correct designs is quickly becoming the bottleneck in the design of complex digital systems. In this paper we discuss our experience with developing and implementing a novel transformationbased design methodology for the design of guaranteed correct synchronous digital systems. By applying user-selected behavior-preserving transformation steps(More)
The proliferation of multimedia information sources and the availability of large capacity consumer storage devices, raise the need to present video in compact forms so that users can effectively access interesting parts to watch. Aiming at an implementation in consumer electronics products and targeting to non-IT-expert users, an innovative user-friendly(More)
| TRADES is a transformation based system for high-level synthesis. Behavior preserving transformations are applied to a control-data ow graph (SIL) to derive an e cient hardware implementation. This is demonstrated by means of the design of a six-constant multiplier as used in a DCT for image compression. A novel syntax-based translation is used to(More)
In this paper, a novel multi-target design methodology based on the concepts of transformational design, and its application to the interlaced-to-progressive scan conversion (IPSC) problem, are discussed. Current high-level synthesis methodologies are restricted to a relatively fixed application domain and target architecture. This approach is too limited(More)
The characteristics of PCs, huge storage capacity, tremendous processing power, and high flexibility are becoming available for consumer devices like set-top boxes, TVs, and VCRs. Interconnection of these devices and wireless communication with various portable devices will create a complex home system with the capacity to store many types of data and offer(More)
The convergence era has begun raising the need for intelligent assistance in the large amount of multimedia content already available in the home environment. In this paper we present a Personal Video Recorder that exploits meta-data obtained from a service provider or locally generated, to provide users with profile-based filtering and innovative(More)
