Analysis of Impulse Noise Mitigation Techniques for Digital Television Systems

are inherently more resistant to impulse noise than single carrier systems, impulse noise can still be a significant problem in many applications including digital television. A number of impulse noise mitigation algorithms are investigated. These use non linear processing on the digital input signals to limit the size of impulses reaching the demodulator. It is shown that when the noise at the...

Reflective Optical Pickup For Violin

We present here the development of optical pickup for acoustic violin. Unlike other optical pickups, this one works in a reflective mode which is potentially less intrusive. This pickup, aimed principally at pitch tracking, uses a modulation technique to improve the signal-to-noise ratio, and limit artifacts of the ambient light.

Modeling Television Schedules for Television Stream Structuring

TV stream structuring is very important for huge archives holders like the French National Institute, the BBC or the RAI, because it is the first necessary step to describe the various telecasts broadcast on various channels. It is also necessary for television ratings in order to isolate the telecasts that must be rated. One can think this structuring is a simple alignment of the TV guides on ...

Customized television: standards compliant advanced digital television

This correspondence describes a European Union supported collaborative project called CustomTV based on the premise that future TV sets will provide all sorts of multimedia information and interactivity, as well as manage all such services according to each user’s or group of user’s preferences/profiles. We have demonstrated the potential of recent standards (MPEG-4 and MPEG-7) to implement suc...
