Program unit, particularly for digital, data-compressed video distribution signals

Abstract

For the transmission of ATM digital signals of a program unit, particularly of digital, data-compressed video distribution signals, from a remote digital signal source, particularly a video server, via a head station of a light waveguide and/or coaxial line tree network respectively shared by a plurality of subscriber-side network termination units to at least one of the subscriber-side network termination units, whereby an intermediate storing of such ATM digital signals transmitted with elevated data rate occurs in the head station, the program unit is transmitted from the digital signal source to the intermediate memory of the head station with a data rate that is slightly elevated compared to the data rate nominally required for the program unit and that is retained for the entire duration of the transmission, the data stream being further-transmitted therefrom to the respective subscriber with the signal clock nominally required for the program unit that is offered by a reference clock source; the reference clock(s) is (are) thereby separately transmitted at any rate from the head station to all network termination units connected to the light waveguide and/or coaxial line tree network, whereat the digital signal acquired from the received ATM cells is thus time-regenerated.
