DVB-C, S, T digital TV equipment (overview)


   The company Beta TV com develops and manufactures the whole range of the equipment for arrangement of TV broadcasting in a digital format in the DVB-C, DVB-S and DVB-T standards.
   Digital TV modules and units, head-end and subscriber receivers for digital signal reception of the DVB-C, T, S standards are manufactured.
   The digital TV modules enable shaping of practically ane signals in the DVB-C, T and S standards and "transfer" from one standard into another one.
