To implement HDMI input port on our system we are planning to interface output of ADV7611 which is configurable to below formats to the Image sensor Controller of SAMA5D2 for receiving the data being converted from HDMI to TTL.
8-/12-bit ITU-R BT.656 4:2:2 YCrCb with embedded time codes and/or HS, VS, and FIELD output signals
• 16-/24-bit YCrCb with embedded time codes and/or HS and VS/FIELD pin timing
• 24-bit YCrCb/RGB with embedded time codes and/or HS and VS/FIELD pin timing
Is there any foreseen challenge in doing this. What is the purpose of isc_field signal? where should I connect it to ADV7611.
For detail of connections we are planning to do please refer the attachment.
