7.1.3. Sink Auxiliary Decoder

The sink core decodes the auxiliary data path into a 72-bit wide standard packet stream. The stream contains a valid, start-of-packet (SOP) and end-of-packet (EOP) marker.
Figure 33. Auxiliary Data Stream SignalThe figure below shows the relationship between the data bit-field and its clock cycle based on 1-, 2-, or 4-symbol per clock mode.

The data output at EOP contains the received BCH error correcting code. The sink core does not perform any error correction within the core. The auxiliary data is available outside the core.

Note: You can find the bit-field nomenclature in the HDMI 2.0b Specification.
