48、audio channelthat is carried in that same subframe. Channel status information is organized ina 192-bit block,subdivided into 24 bytes,numbered0 to 23 (see Table 1). The first bit of each channel status block is carried in the frame with preamble “B”.The individual bits of a channel status block are
49、 numbered 0 to 191. The primary application is indicated by channel status bit 0. As stated in IEC 60958-1, for the consumer digital audio applications described in this standard, this first channel status bit equals “0”.NOTE As stated in IEC 60958-1, for professional application this first channel statusbit equals “1”.
