Versatile multistandard digital TV encoder based on programmable hardware (CPLD)

After giving a description of the three underlying standards of the digital video broadcasting system (DVB-S: satellite, DVB-C: cable and DVB-T: terrestrial), this paper discusses the synergy effects, which can be used to design a versatile multistandard digital television encoder with minimum hardware requirements. The paper shows the implementation possibilities of the signal-processing algorithms in Complex Programmable Logic Devices (CPLDs) for the example of a highly integrated digital TV encoder, which has been realized at the Chair of Communications Technology for measurement purposes.
