SPARE PACKETS AND VSI SUPPORT
to send any type of packets or InfoFrames via the spare packets controls and associated configuration
features four such spare packets that can be enabled via the
, and
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
to support the transmission of three Vendor Specific InfoFrames (VSI) as follows: VSI-Video, VSI-AUDIO and VSI-HDMI.
