Definitions

  • the invention relates to a method for simultaneous Transmission of audio signals from N signal sources via a corresponding number of transmission channels in which the individual Signals divided into blocks and the blocks by one Transformation or filtering implemented in spectral coefficients which are subjected to a data reduction process, and the total available transmission capacity and the currently required total transmission capacity the allocation to maximum available standing transmission capacity for each individual signal calculated and each individual signal determined with this Capacity is encoded and transmitted.
  • the invention has for its object a method for the simultaneous transmission of audio signals from N signal sources over a corresponding number of transmission channels specify with which "data-reduced Signals "via transmission channels that are only for an "average need” are dimensioned without perceptible, i.e. for example, audible losses Signal capacity can be transmitted.
  • the invention is based on the basic idea of Compensate for fluctuating needs at the same time Transmission of audio signals from N signal sources via a corresponding number of transmission channels Allocation to the individual signals not according to statistical Aspects, but already in the process step in which the signals for data reduction are encoded, the fluctuating demand to compensate for corresponding measures.
  • a perception-specific model for example when transferring Audio signals can be a psycho-acoustic model the permitted fault is determined for each section and from this the requirement for currently required Total transmission capacity calculated.
  • the calculation the total transmission capacity i.e. the necessary Number of bits, occurs for all blocks at the same time. From the total available transmission capacity and the currently required total transmission capacity the allocation to the maximum available transmission capacity calculated for each individual signal. With the "number of bits" allocated for each individual signal the individual signal is encoded and accordingly the transmission of this single signal.
  • each is balanced required transmission capacity only between the Channels.
  • a reserve of transmission capacity a so-called Bit reservoir available from which in the event that the total transmission capacity required on average available transmission capacity exceeds an allocation of transmission capacity is made.
  • This bit reservoir is always filled up when the requested transmission capacity is less than that available transmission capacity is (Claim 3).
  • the first Pass each from the lowest bands Tape one bit / ATW provided until the available number of bits is reached.
