1. 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, by including software which is able to choose between unequal connection lines based on criteria for capacity and cost, characterized in that 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 part of the signal, is transmitted from the transmitter over a channel with particularly high capacity, 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, a supervision of the received, non-used data is carried out in a buffer storage at the receiver, by registering non-used data (buffer amount) below a certain level at the receiver a warning signal is sent from the receiver to the transmitter, at receipt of said warning signal the transmitter initiates transmitting to the receiver of a further data packet (I1

  • ) of the signal over the channel with high capacity, and thereafter to continue with transmission of a further signal amount (I2

    ) over the narrowband channel, this alternating transmission continues to save transmission capacity over the broadband connection and at the same time to maintain a transmission capacity which results in a satisfying data content in the transmitted signal.
