Introduction

-This plugin can be used to view digital amateur analog television transmissions a.k.a DATV. The only supported standard for now is DVB-S in various modulations. The standard modulation is QPSK but experimental configurations with other PSK modulations (BPSK, 8PSK, QAMn) can be selected. +This plugin can be used to view digital amateur analog television transmissions a.k.a DATV. The only supported standard for now is DVB-S in various modulations. The standard modulation is QPSK but experimental configurations with other PSK modulations (BPSK, 8PSK, QAMn) can be selected. The whole bandwidth available to the channel is used. That is it runs at the device sample rate possibly downsampled by a power of two in the source plugin. @@ -60,8 +60,8 @@ For now only the DVB-S standard is available - APSK64e: amplitude and phase shift keying with 64 symbols - QAM16: quadrature amplitude modulation with 16 symbols - QAM64: quadrature amplitude modulation with 64 symbols - - QAM256: quadrature amplitude modulation with 256 symbols - + - QAM256: quadrature amplitude modulation with 256 symbols +
