1. A method for transmitting information from a transmitter to a receiver comprising:
- generating a signal carrying said information,generating signal fragments from said signal by fragmenting said signal into time increments based upon the time priority, addressing conditions, information content and signal character agreed-to between said transmitter and receiver,assigning an index to each said signal fragment, said index specifying the time position of said fragment within said signal,providing a coordination chart to said transmitter and receiver, said coordination chart identifying which index corresponds to which time position within said signal,selecting at least one channel based on the loading, cost structure and transmission capacity of the channel relative to the character of the signal and based on the selective addressing facilities of the channel and the prevailing risk of unauthorized utilization,transmitting said signal fragments on said selected channel from said transmitter to said receiver,reassembling, at said receiver, said signal from said signal fragments with the aid of said coordination chart.

Abstract
In a transmitter, information for transmission is received in the form of a digital signal, electrical or optical, which is converted into short signal fragments, each of which is assigned an index. A transmitter module distributes these fragments to one or more receivers through a number of available communication channels, the choice of channel depending on the capacity and availability of the particular transmission channel. In the receiver, the signal fragments are coordinated according as they are controlled by means of their indices, to produce a signal capable of generating an information display.

3. A method of compressing a signal for transmitting information from a transmitter to a receiver, said method comprising
generating a signal carrying said information, compressing said signal into a compressed signal, generating signal fragments from said compressed signal by fragmenting said compressed signal into time increments, analyzing each said signal fragment to ascertain the feasibility of further compression, further compressing said signal fragments depending upon the results of the analysis, and transmitting said compressed signal fragments from said transmitter to said receiver.

6. A method of security coding a transmission of information from a transmitter to a receiver, said method comprising
providing to said transmitter and receiver a chart which is variable with time and/or with the utilization sequence such that different encryption is applied on different occasions of communication between said transmitter and receiver; -
said chart comprising encrypted address codes and/or authorization codes and/or encryption procedures, and applying address codes and/or authorization codes and/or encryption procedures during transmission from said transmitter to said receiver to protect said information from unauthorized access. - View Dependent Claims (7, 8, 12, 13, 14)
