6.6. SPARE PACKETS AND VSI SUPPORT

The user may configure the
registers. The ADV8005 features four such spare packets that can be enabled via the spare_pkt0_en, spare_pkt1_en, spare_pkt3_en, and
spare_pkt4_en controls bits. When a spare packet is enabled, the Tx transmits one of these enabled spare packets once every two video fields.
No control exists over the specific timing when these are sent; however, it is always before the leading edge of VSYNC. These spare packets allow
the ADV8005 to support the transmission of three Vendor Specific InfoFrames (VSI) as follows: VSI-Video, VSI-AUDIO and VSI-HDMI.
