    The BluetoothTM wireless technology is a cable replacement technology that exploits the wireless interconnectivity that is possible with radio. Bluetooth chips are already available and early applications include cordless connections from mobile phones to laptop computers and wireless headsets. Even if only 10% of mobile phones and computers were to incorporate Bluetooth chips, then the... View full abstract»

    Digital Radio Mondiale (DRM) is a system that promises to reinvigorate the use of the broadcasting bands below 30 MHz. It offers a dramatic improvement in audio quality, not only improving the audio bandwidth and signal-to-noise ratio, but also countering the effects of selective fading and audible interference from other stations. It is also designed to support various features that will make rec... View full abstract»

    In this paper, pen computing, i.e. the use of computers and applications in which the pen is the main input device, are described from four different viewpoints. Firstly a brief overview of the hardware developments in pen systems is given, leading to the conclusion that the technological developments in this area have not led to the expected user acceptance of pen computing. The reasons underlyin... View full abstract»

    Coded modulation has had a very significant impact on the communications scene in the decade or so since its introduction, finding practical applications from voice-band modems for telephone lines to deep-space communications. The paper introduces the principles of coded modulation and describes the two main schemes: block coded modulation (BCM) and trellis coded modulation (TCM). In particular it... View full abstract»

    There is an urgent need to extract key information from video automatically for the purposes of indexing, fast retrieval, and scene analysis. To support this vision, reliable scene change detection algorithms must be developed. Several algorithms have been proposed for both sudden and gradual scene change detection in uncompressed and compressed video. In this paper some common algorithms that hav... View full abstract»
