The bit rate is reduced by transmitting only 10 bits plus parity of each 14 bit sample, the largest sample in a frame determines - which 10 bits are transmitted. The parity bits for audio samples also + which 10 bits are transmitted. The parity bits for audio samples also specify the scaling factor used for that channel during that frame. The companeded audio data is interleaved to reduce the influence of dropouts and the whole frame except for sync bits is scrambled for spectrum shaping. |
