Definitions
- the invention relates to a ner driving according to the preamble of claim 1.
- a ner driving is known from the earlier patent application P 41 11 131.1.
- bit-saving source codes are usually used before the channel coding, which are based on a reduction in redundancy and irrelevance.
- the digitally sampled audio signal is processed using a filter bank
- sampled values 25 subband samples and / or converted to spectral samples using a frequency domain transform.
- additional and control information such as, for example, scale factors, scale factor selection information and bit allocation information
- Binary digits within an information block produce a different subjective interference effect on the listener.
- the disruption of a bit assignment in the radio 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 small 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 from transmission disturbances, which can be determined by suitable ones
- Fig. 1 is a schematic representation of a in the invention
- Method used information block which consists of a sequence of nine information units with different error protection
- Fig. 2 is a schematic representation similar to that in Fig. 1 for a alternative embodiment
- FIG. 3 shows a schematic representation of the two channels of a stereophonic audio signal which is channel-coded according to the inventive method according to FIG. 2 after channel decoding.
- a sub-band method is used as the source coding method, in which the frequency band of the digitized audio signal is split into a plurality of sub-bands. Each subband is assigned to one of six subband groups. The bit allocation and thus data reduction of the sample values of each subband is carried out according to psychoacoustic aspects (monitoring threshold calculation). The peak value of the amount of these samples is determined in each sub-band for a certain number of consecutive samples and is quantified as a so-called "scale factor" and recorded together with the data-reduced ones
- Such a data-reduced, channel-coded audio signal 1 is shown schematically in the figure and consists of a large number of successive information blocks 10.
- the information blocks 10 are preferably of the same length and each comprise a sequence of nine information units 11 to 19 in the example shown.
- the nine information units 11 to 19 contain the following information in accordance with the source coding scheme under consideration: Unit 11 bit allocation information
- Unit 12 scale factor selection information
- the individual information units 11 to 19 are assigned a varying bit error protection 21 to 29 during the channel coding.
- the bit allocation information 11 and the scale factor selection information 12 require a high level of error protection 21 and 22, respectively, since bit errors within these information units can lead to a complete destruction of the audio signal at the output of the source decoder. Since disrupted scale factors 13 subjectively are extremely disruptive, they also require a relatively high level of error protection 23.
- Subband groups No. 1 to No. 6, which are shown as information units 14 to 19, are treated differently with regard to their error protection 24 to 29.
- the subband samples of the subbands of the lower frequency range are in the information unit 14, those of the highest frequency range to be transmitted are in the information unit 19.
- FIG. 2 An application of this better error detection is shown in FIG. 2 using a two-channel, stereophonic audio signal. In each of the two channels No. 1 and No. 2, three successive information blocks 110, 120, 130 and 210, 220, 230 are illustrated. Each of these blocks, as shown for block 10 in FIG. 1, consists of nine information units.
