    Hi Lee,

    System_Buffer struct has a “chNum” field which allows a link to identify the channel with the buffer data. You can check slide "Inter Link API – System Buffer" in vision_sdk\docs\Architecture\VisionSDK_SW_Architecture_Overview.pdf and vision_sdk/links_fw/include/link_api/system_buffer.h for details.

    Regards,
