Abstract :
Describes the hardware and software development of a low cost, 100 kbit/sec data modem for satellite broadcasting and reception of computer disk files. Primarily developed for use as a sub-carrier on a standard FM TV transmission, the system has been adapted to operate at 128 kbits/sec utilising a user data port on an MPEG compressed digital TV channel. The modulator and demodulator printed circuit cards have been developed which plug directly into IBM AT compatible PCs (personal computers). Applications include distance learning, electronic mail, information service, database updating and software distribution
