Method for receive-side clock supply for video signals digitally transmitted with ATM in fiber/coaxial subscriber line networks

A method for a receive-side clock supply for digital signals, comprising the steps of:

• transmitting digital signals from at least one digital signal source via a connection unit and via at least one of a light waveguide tree network and/or coaxial line tree network, shared respectively in common by a plurality of subscriber-side network termination units, to the subscriber-side network termination units in the form of ATM signals;
• transmitting a signal clock, separate from the ATM digital signal, in the form of pilot signals from the connection unit to each of the network termination units connected to the light waveguide tree network and/or coaxial line tree network;
• receiving the transmitted clock signal and the transmitted ATM signals in each of the network termination units;
• and time-regenerating, using the received clock signal, digital signals acquired from received ATM cells in the received ATM signals in the network termination units.

A method for a receive-side clock supply for digital data-compressed television distribution signals, comprising the steps of:

• transmitting digital signals from television signal sources via a connection unit and via at least one of a light waveguide tree network and/or coaxial line tree network, shared respectively in common by a plurality of subscriber-side network termination units, to the subscriber-side network termination units in the form of ATM signals;
• transmitting a signal clock, separate from the ATM digital signals, in the form of pilot signals from the connection unit to each of the network termination units connected to the light waveguide tree network and/or coaxial line tree network;
• receiving the transmitted clock signal and the transmitted ATM signals in each of the network termination units;
• and time-regenerating, using the received clock signal, the digital data-compressed television distribution signals acquired from the received ATM cells in the received ATM signals in the network termination units, wherein given frequency synchronization of television signal sources and of the connection unit via a common network clock, clock frequencies, that are numerically derived from a clock frequency of the network clock transmitted downstream to all network termination units, are employed for the digital data-compressed television distribution signals.
