Method for ordering and transmission of digital data, particularly video
signals, from a transmitter to a single receiver or a group of receivers
where other transmission channels are searched for finding a reasonable
alternative. A data signal is sent with a request for transmission of a
determined video signal from a receiver to a transmitter. A data packet
(I1), being a first part of the signal, is transmitted from the
transmitter over a satellite channel. A following part of the signal is
transmitted as another data packet (I2) over a narrowband communication
channel, such as a low-cost Internet channel. Supervision of the received
non-used data amount is carried out in a buffer storage at the receiver.
By registering non-used data (buffer amount) at the receiver below a
certain level a warning signal will be sent from the receiver to the
transmitter. When receiving this warning signal the transmitter initiated
transmission to the receiver of a further data packet (I1') of the signal
over the satellite channel, for thereafter continuing with transmission
of a further signal amount (I2') over the narrowband channel. This
alternating transmission will be continued to save transmission capacity
over the satellite connection and at the same time to maintain a
transmission capacity which results in a satisfying data content in the
transmitted signal.
