The Proposal of OFDM Conversion and Switching of Multi-Channel Terrestrial Digital Broadcasting Signals Using the Same Broadcasting Information

Abstract

This paper proposes OFDM conversion and switching of multi-channel terrestrial digital broadcasting signals using the same broadcasting information. It is economically better since multi-channel is converted collectively to the OFDM signals with just a single modulator of transmitting equipment in a PA system or cable television station. It is applicable to every home television and no special equipment required.
