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 Specification Ver.2.0. Sink Auxiliary Packet Capture The auxiliary streams transfer auxiliary packets. The auxiliary packets can carry 15 different packet types. The module produces 4 valid signals to simplify the user logic. To simplify user applications and minimize external logic, the HDMI core captures 3 different packet types and decodes the audio sample data. These packets are: General Control Packet, Auxiliary Video Information (AVI) InfoFrame, and HDMI Vendor Specific InfoFrame (VSI). HDMI Sink Send Feedback Altera Corporation
