Definitions

  • the invention relates to a method according to the preamble of claim 1.
  • Such a method is known from the international publication WO, A, 92 179 48 published on October 15, 1992.
  • bit-saving source codes are usually used before the channel coding, which are based on a reduction in redundancy and irrelevance.
  • additional and control information such as, for example, scale factors, scale factor selection information and bit allocation information
  • additional and control information are transmitted, ie successive information units of different content must be transmitted, a sequence of such information units being combined to form an information block (also called an “information frame”) is.
  • Bit error individual Binary digits within an information block produce a different subjective interference effect on the listener. For example, the disruption of a bit assignment in the broadcast channel can briefly lead to a complete failure on the playback side and thus to a muting of the audio signal of a certain duration.
  • This control information must therefore be protected considerably more than the encoded samples.
  • the listener can only perceive a bit error of a low-value binary position of the encoded sample with difficulty and sometimes even not at all.
  • the object of the invention is to provide, in a method of the type mentioned at the outset, a channel coding which is optimized with regard to minimal subjective interference, minimum data rate and maximum error protection.
  • the invention is based on the consideration of using the different meaning of the information units within each information block for a continuously graduated, variable error protection in such a way that certain interference patterns result in the case of transmission disturbances, which can be well concealed by suitable techniques. By permitting these error patterns, the data rate for transmission can be reduced since less data than in the prior art are required for adequate error protection.
