MPEG2 manipulator

Description

Development of three modules for a television head-end system.

  • DVB-S to DVB-C
  • DVB-S2 to DVB-C
  • DVB-T to DVB-C

Television head-ends are used to feed analog and digital television cable networks. So the primary function of a head-end is the translation of television signals from one format into cable specific formats.
