Another section of the PBS TOS-1 2010 Edition:
4.4 Active Format Description (AFD)
4.4.1.1 An AFD code must be placed on line 11 of every field of every frame of each segment including the pre- and post-segment black portions.
4.4.1.2 Only the following 16:9 coded frame AFD codes may be used:
4.4.1.2.1 4.4.1.2.2 4.4.1.2.3
4.4.1.2.4
AFD code 1000 (8) –– Full frame 16:9 image AFD code 1001 (9) –– 4:3 pillarbox image centered in frame
AFD code 1010 (10) –– Full frame 16:9 image – All image area is protected, cropping is not allowed
AFD code 1111 (15) –– 16:9 image with alternate 4:3 center – Visual information outside 4:3 protected area may be cropped with minimum impact for the viewer
Note: Currently AFD data will be overwritten during the PBS containerization process using the AFD code submitted in the Orion Media inventory submission for each segment.
Now where in the food chain is AFD inserted? Is it during Closed Captioning? What does the note that AFD data gets overwritten during PBS containerization mean they are going to insert their own based on the "Orion Media Inventory"? My brain is thinking it's time to start hurting.
