Development of HDTV digital transmission system through satellite

A HDTV digital transmission system through satellite has been developed. This system has been designed to utilize QPSK modulation via a 36 MHz bandwidth Ku band transponder. Convolutional code and Reed-Solomon code are applied for the purpose of error protection. The system provides the transmission rate of 40 Mbps for video. A HDTV codec has been fabricated for the system. A transmission experiment has been carried out and gave excellent transmission performance.<
