The apparatus is configured to encode the metadata in an auxiliary video information (AVI) information frame (InfoFrame). The apparatus is further configured to transmit the AVI InfoFrame during a frame synchronous transmission window (FSTW) of the video data, wherein the FSTW begins during a video blanking interval (VBI) of the video data, on a first video blank pixel that immediately follows a last active video pixel of a preceding video frame or video field and ends a predetermined number of video lines after a start of the VBI."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Frame synchronous packet switching for high-definition multimedia interface (HDMI) video transitions","description":"An apparatus for use in a high-definition media interface (HDMI) source device includes an HDMI interface for transmitting video data and metadata to a sink device.
