A Demodulator (short Demod) recovers (demodulates) the original information from the received and downconverted RF signal. In case of digital TV this is the MPEG2 Transport Stream, in case of analogue TV the Composite Signal.
Digital Demodulators also perform Forward Error Correction (Convolutional Viterbi- and Block-Reed-Solomon-Decoding).
