Abstract:
1. A method for operating a coding apparatus comprising at least a first coder and a second coder that are interconnected, a processor unit, and a processor unit memory, comprising: providing a multiple compression coding via a plurality of coding techniques by the interconnected first coder and second coder; feeding a common input signal in parallel to at least the first and second coder, each coder comprising a succession of functional units for compression coding of said input signal by each of the first and second coders, the first and second coders respectively comprising at least a first and a second shared functional unit for performing common operations; calculating, by at least a part of the functional units with the processor unit, respective parameters for coding of the input signal by each coder; performing calculations for delivering, across a coder interconnection, a same set of parameters to the first functional unit and to the second functional unit in a same step and in a shared functional unit for processing of the common input signal by the coders; if at least one of the first and the second coder operates at a rate that is different from a rate of a common functional unit, adapting the parameters to the respective rate of at least one respective said first coder and said second coder in order to be used by the at least one of said first and second functional unit respectively; and if the first and the second coders operate at a rate that is the same as a rate of the common functional unit, then providing the parameters to the first and second functional units without adaptation.
