Patent ID: 7304953

Claim:
Method for ordering and transmission of video signals from a transmitter to a single receiver or a group of receivers in which several transmission channels are searched to locate alternatives by choosing between unequal connection lines based on criteria for capacity and cost, comprising the steps of: sending from a receiver to a transmitter, a data signal with a request for transmission of a predetermined video signal, transmitting from the transmitter to the receiver a data packet which is a part of the predetermined video signal, over a channel with high capacity, transmitting another data packet which is a following part of the predetermined video signal from the transmitter to the receiver over a lower capacity communication channel, supervising received and non-used data in a buffer storage at the receiver, registering non-used data below a predetermined level in the buffer storage, and sending thereby a warning signal from the receiver to the transmitter, at receipt of said warning signal, causing the transmitter to initiate transmission to the receiver of a further data packet of the signal over the channel with high capacity, and thereafter continuing with transmission of further data packets over the lower capacity channel, thereby alternating transmission between the high capacity channel and the lower capacity channel, to save transmission capacity over the high capacity channel, while maintaining a transmission capacity which results in a sufficient data content in the transmitted signal.
