Abstract: Digital modulation methods for TV satellite transmission can offer advantages in satellite transmission power and bandwidth if the bit rate can be reduced to 34 Mbit/s (to 34.368 Mbit/s, the bit rate for 480-channel PCM systems). A very efficient coding technique, differential pulse code modulation (DPCM), is described, and its application for TV transmission is shown. A test system for demonstrating the feasibility of digital TV transmission is described in detail. In this system the composite TV signal is split into its luminance and chrominance components. Tests via directional radio and satellite line have been carried out using a modem with 4-PSK (phase-shift-keying) as interface. After DPCM encoding these picture signals and accompanying sound signals are multiplexed and transmitted together with a code word for synchronization. On the receive side the signals are demultiplexed and after decoding are provided as analog signals. An example of digitally transmitted pictures is given to show that good picture quality has been achieved.
