Transparency Default channel status and User data applied to all re-synchronised
outputs.
Default Channel Status bits set to:
• Consumer Use of Channel Status (bit 0) = Professional (1)
• Linear PCM Identification (bit 1) = PCM Data Carried (0) or
Non PCM data carried, e.g. Dolby data (1)
• Sampling Frequency (bits 6 & 7) = 48kHz (0 & 1), 44.1 kHz
(1 & 0) or 32 kHz (1 & 1) or Not Indicated (0, 0)
• Sampling Frequency (bits 35 to 38) = 96 kHz (0, 1, 0, 0),
192 kHz (1, 1, 0, 0) or Not Indicated (0, 0, 0, 0)
• Use of Auxiliary Sample Bits (bit 18) = 24 bit format (1)
• All other default channel status bits set to Zero (0)
Default User Data bits set to:
• All bits set to Zero (0)
