Video resolution enhancement takes important place in various application areas. One of significant application areas is standard-definition (SD) video processing to get high-definition (HD) content for television and broadcast. However, due to many reasons high-quality up-conversion is still a challenging task. We can overcome this using stereo camcorder. The author propose practical super-res...

The evolution in satellite digital broadcast has lead to wide variety of Internet and multimedia applications even in few first years of service launch. DVB is expected to be prominent television broadcast standard for next decades also in terrestrial television. While being member of same protocol family, terrestrial digital television (DVB-T) sets quite different constraints on performance th...

The isotemporal substitution model (ISM) was previously developed as a methodology to study the time-substitution effects of 1 type of activity for another in a data setting with continuous outcomes. To demonstrate the application of ISM with a dichotomous outcome, we prospectively examined the associations of different activities with various activity displacements with depression risk among 3...

Digital HDTV, on the other hand, needs a considerably greater bitrate and – regardless of the modulation scheme adopted – transmission via traditional broadcast channels is impossible without the application of advanced video compression tech...
