    Proposed in this paper is a scheme to modify NTSC video signals to render the signal unrecordable by video recorders, yet viewable on standard television displays. This method is based on continually varying timing characteristics in the transmitted video signal. Protection of copywrited broadcast material from casual consumer or illicit professional recording would be possible with this implement... View full abstract»

    Satellite television systems may employ subcarriers for additional transmission of data via the same channel thus utilizing satellite transponders more efficiently. Data-rate and bit-error-rate of such systems are ultimately limited by maximal-permissible subcarrier levels which would not degrade the picture quality significantly. View full abstract»

    A Doherty system combines the outputs of two or more linear RF power amplifiers (PAs) through an impedance-inverting coupler such as a quarter-wave transmission line. At low output levels, the first PA operates linearly, reaching saturation (and maximum efficiency) at some transition voltage below the system peak-output voltage. At higher output levels, the first PA remains saturated and the secon... View full abstract»

    At this point in time, with the advent of high powered Ku band direct broadcast satellites (DBSs) and the ever increasing requirement for TV via satellite, it is safe to say that satellite rooftop receiving antennas will soon shrink in size. This will be true for DBS systems operating in the Ku DBS band, since Ku band EIRP has been increased considerably over C band EIRP. It will not necessarily b... View full abstract»
