CODING INFORMATION WITHOUT LOSS WITH GUARANTEED MAXIMUM BIT SPEED Russian patent published in 2009 - IPC H03M7/30 

FIELD: physics; communication.

SUBSTANCE: invention relates to coding information values without loss and, particularly to the concept of guaranteeing maximum bit speed for coded presentation of information values. A compact coded presentation of information values, which does not exceed a predetermined size, can be obtained when the first coding rule, which generates the coded presentation of information values with varying length, is compared with a second coding rule, which generates a coded presentation of information values with fixed length, and when a coding rule, which leads to a coded presentation which requires a lesser number of bits, is chosen. That way, it can be guaranteed that, maximum bit speed will not exceed maximum bit speed of the second coding rule, in accordance with which the second coded presentation is obtained. Through transmission of signals for selecting the coding rule through a certain information rule together with coded presentation of information values, correct information values can be obtained later at the decoder side, using a decoding rule which corresponds to the coding rule, used during coding.

EFFECT: more accurate information display.
