Claims (17)
1. Digital bitstrøm, der omfatter databits, der repræsenterer lyd (101), metadata for lyden (101) og metadata-verifikationsinformation, hvor metadata- verifikationsinformationen indbefatter en kopi, eller en datakomprimeret kopi, af metadataene, hvor verifikationsinformationen er anvendelig til at detektere, hvorvidt eller ikke metadataene og kopien deraf ligger inden for en tærskelforskel af hinanden, og hvis de ikke gør, at erstatte metadataene med kopien.
2. Digital bitstrøm ifølge krav 1, hvor metadata- verifikationsinformationen er krypteret.
3. Digital bitstrøm ifølge et hvilket som helst af kravene 1-2, hvor bits, der repræsenterer metadata- verifikationsinformationen, erstatter alle eller nogle af en flerhed af bits i bitstrømmen, der normalt ikke bærer nogen information.
4. Digital bitstrøm ifølge et hvilket som helst af kravene 1-3, hvor metadata-verifikationsinformationen er steganografisk kodet i bitstrømmen.
5. Digital bitstrøm ifølge et hvilket som helst af kravene 1-4, hvor lyden (101) er datakomprimeret lyd.
6. Koder (100), der genererer en digital bitstrøm i overensstemmelse med et hvilket som helst af kravene 1-5.
7. Dekoder, der modtager en digital bitstrøm i overensstemmelse med et hvilket som helst af kravene 1-5, hvor dekoderen dekoder databitsene, der repræsenterer lyd (101), ved anvendelse af metadataene og metadata- verif ikationsinf ormationen .
8. Dekoder ifølge krav 7, hvor dekoderen ved dekodning af databitsene, der repræsenterer lyd, ændrer metadata ved anvendelse af metadata-verifikationsinformationen og anvender sådanne ændrede metadata ved dekodning af lyden (101).
9. Fremgangsmåde til generering af en digital bitstrøm som reaktion på lyd (101), hvor fremgangsmåden omfatter generering af metadata til lyden (101), generering af metadata-verifikationsinformation, hvor metadata-verifikationsinformationen indbefatter en kopi, eller en datakomprimeret kopi, af metadataene, hvor metadata- verif ikationsinf ormationen er anvendelig til at detektere, hvorvidt eller ikke metadataene og kopien deraf ligger inden for en tærskelforskel af hinanden, og hvis de ikke gør, at erstatte metadataene med kopien, og assemblering af en digital bitstrøm, der indbefatter databits, der repræsenterer lyden, metadataene og metadata- verif ikationsinf ormationen .
10. Fremgangsmåde ifølge krav 9, hvor genereringen af metadata genererer metadata, der er baseret på en måling af lyden (101).
11. Fremgangsmåde ifølge krav 10, hvor målingen af lyden (101) er en måling af lydstyrken af lyden.
12. Fremgangsmåde ifølge et hvilket som helst af kravene 9- 11, hvor metadata-verifikationsinformationen, der anvendes til at detektere og ændre metadata, indbefatter en kopi, eller en datakomprimeret kopi, af en korrekt version af sådanne metadata.
13. Fremgangsmåde ifølge et hvilket som helst af kravene 9- 12, hvor verifikationsinformationen er krypteret.
14. Fremgangsmåde ifølge et hvilket som helst af kravene 9- 13, hvor bits, der repræsenterer metadata- verif ikationsinf ormationen, erstatter alle eller nogle af en flerhed af bits i bitstrømmen, der normalt ikke bærer nogen information.
15. Fremgangsmåde ifølge et hvilket som helst af kravene 9-13, hvor verifikationsinformationen er steganografisk kodet i bitstrømmen.
16. Fremgangsmåde til behandling af en digital lyd-bitstrøm, der indbefatter databits, der repræsenterer lyd (101), lyd-metadata og lyd-metadata-verifikationsinformation, hvor lyd-metadata-verifikationsinformation indbefatter en kopi, eller en datakomprimeret kopi, af lyd-metadataene, hvor verifikationsinformationen er anvendelig til at detektere, hvorvidt eller ikke metadataene og en sådan kopi deraf ligger inden for en tærskelforskel af hinanden, og hvis de ikke gør, at erstatte metadataene med kopien, omfattende ændring (403) af metadataene, og ændring (403) af verifikationsinformationen, således at metadataene og kopien, eller datakomprimeret kopi, af metadataene ligger inden for tærskelforskellen af hinanden.
17. Computerprogram, der er lagret på et computerlæsbart medium, til at foranledige en computer til at udføre fremgangsmåden ifølge et hvilket som helst af kravene 9 til 16.
