Coreworks releases the CWda42 SDI Audio de-Embedder
The CWda42 implements an ancillary data packet embedder for SDI. It is able to insert the contents of one audio group (4 channels). This implementation is restricted to 20 audio bits per sample, hence the extended data structure described in the ANSI/SMPTE 272M standard (data extension to support 24 audio bits per sample) is not implemented in the present version. The CWda42 uses two clocks. All input signals are sampled on the rising edge of the audio clock signal. The other clock, video clock, is used to output the auxiliary data. The video and audio clocks must be derived from the same source. The audio samples inputs use the CW_LINK format. AES auxiliary information is also inserted in the ancillary packets. This information includes the Validity, Channel Status, and User bits.
