发明名称 Method for transmitting subscriber-individual services and distribution services
摘要 For the transmission of subscriber-individual services (VoD) and distribution services (NVoD), digitised frequency-division multiplex group signals are formed which are transmitted group by group in time-division multiplex. Especially for injecting these supplementary services into existing distribution networks, these are converted into such frequencies that no overlap can occur. The invention is advantageously suitable for transmitting video on demand signals via existing network topologies. <IMAGE>
