Placement positions value 16 means L shape
The content shrinks into a corner and the ad fills an L-shaped band along two edges of the screen.
When to send it
Value 16 is the classic L-shaped squeezeback: program video is scaled down and the ad fills a band along one side and the bottom of the screen. It was added in AdCOM 1.0-202607 and is sent in Video.pos with a video plcmt of 8 (Squeezeback). AdCOM names the shape but does not fix its orientation; the usual reading follows the letter, with the band down the left side and along the bottom.
Buyers need to know which edges are free so they can send matching artwork, which is why the list keeps 16 apart from 17 (Reversed L shape). Agree on orientation with each seller before relying on either value. It is also confused with 11 (Frame the content), which uses every edge, and with 8 (Partial Screen), the general fallback.
