Abstract:
A method for transmission of ATM digital signals of a program unit comprising digital data-compressed video distribution signals from a remote digital signal source comprising a video server via a head station of a light waveguide or coaxial line tree network to at least one of a plurality of subscriber-side network termination units being fed by the network, comprising the steps of:temporarily intermediately storing ATM digital signals in a buffer memory of the head station, the program unit being transmitted in a data stream from the digital signal source to the buffer memory of the head station with a data rate which is elevated compared to a data rate nominally required for the program unit and which is retained for an entire duration of the transmission;further transmitting the program unit in a data stream from the buffer memory to the respective subscriber termination unit with a reference clock provided by a reference clock source and at said nominally required data rate employed for the program unit; andseparately transmitting the reference clock from the head station to the respective network termination unit connected to the light waveguide or coaxial line tree network so that the digital signals acquired from received ATM cells is time-regenerated.
