Method and apparatus for transmission of data with data reduction
First Claim
1. A method for the transmission of data over a transmission path, from a first station to a second station, wherein said first station edits data to be transmitted and forwards it in edited form as a data block, comprising the steps of:
- dividing the data to be transmitted into one or more sub-sets, suppressing the sub-sets whose information content coincides with a predetermined reference content, transmitting the remaining data sub-sets togethers with the address of the transmitting station, and with a data control identifying a characteristic of the data block, organizing the data network in a tree structure with each station at one network level being connected to a plurality of stations at a lower network level and to one station at a higher network level, and constructing data blocks to be transmitted by stations of said one network level containing the address of said one station, a data control signal in a sequence of the data blocks received from the connected stations of the next lower network level, said data control signal containing information identifying the number of data blocks following said control signal.

Abstract
In a transmission network have a tree structure in which data is forwarded from the tree branches toward the trunk at periodic intervals, the data which is transmitted between the several network levels is reduced by deleting data corresponding to a predetermined information content corresponding to the most probable configuration of such data. The remaining data is divided into sub-sets and transmitted with an individual sub-address for each sub-set, and a control signal identifying the number of sub-sets which are transmitted, and an address identifying the sending station. Optionally, when more than half of the sub-sets contain information not corresponding to the predetermined information, the data blocks are transmitted without sub-addresses but with a control block which identifies a mode in which all sub-sets are transmitted without sub-addresses.

5. A method for the transmission of data over a transmission path, from a first station to a second station, wherein said first station edits data to be transmitted and forwards it in edited form as a data block, comprising the steps of:
- dividing the data to be transmitted into one or more sub-sets, suppressing sub-sets whose information content coincides with a predetermined reference content, transmitting the remaining data sub-sets together with the address of the transmitting station, and with a data control signal identifying a characteristic of the data block, providing an individual sub-address for each of said data sub-sets, and constructing said data control signal to designate the number of data sub-sets in said data block.
