C.10.9.1.5 Waveform Bits Allocated and Waveform Sample Interpretation
Waveform Bits Allocated (5400,1004) specifies the number of bits allocated for each sample, and Waveform Sample Interpretation (5400,1006) specifies the data representation of each waveform sample. Waveform Bits Allocated shall be a multiple of 8. These Attributes are related, and their Defined Terms are specified in Table C.10-10. Table C.10-10. Waveform Bits Allocated and Waveform Sample Interpretation Waveform Bits Allocated - Defined Terms Waveform Sample Interpretation - Defined Terms Waveform Sample Interpretation Meaning 8 SB signed 8 bit linear UB unsigned 8 bit linear MB 8 bit mu-law (in accordance with ITU-T Recommendation G.711) AB 8 bit A-law (in accordance with ITU-T Recommendation G.711) 16 SS signed 16 bit linear US unsigned 16 bit linear 32 SL signed 32 bit linear UL unsigned 32 bit linear 64 SV signed 64 bit linear UV unsigned 64 bit linear NoteThe set of valid values from within this table may be constrained by definition of the IOD (see Section A.34). mu-law and A-law encoding is without the alternate bit inversion used for PCM transmission through the telephone network. This representation also applies to the Channel Minimum and Maximum Data Values, and Waveform Padding Value. |
