Abstract :
A handheld DVB-T TV with a 3.5" LCD panel for mobile entertainment is presented in this work. A dual-board design is used in such a TV receiver. An MPEGII hardware decoder is included to decode the received signals and generate crystal clear terrestrial broadcast DVB-T DTV programs. In addition, an automatic antenna signal detection method is proposed to determine which of the build-in telescopic antenna or an external antenna is selected to deliver the received signal depending on the quality of the received signals individually. Field trials proved that the TV receiver works perfectly at a signal strength -80 dBm with a moderate mobile speed.
