Frame - Aspect Ratio
The desired aspect ratio for the image on screen.
Some video objects produced for display on non-square pixel monitors (i.e. analog TV sets) have a desired aspect ratio that differs from the actual ratio of horizontal to vertical pixels.
Typical NTSC video has an aspect ratio of 4:3. Most HD video (i.e. 1080i, 1080p) has an aspect ratio of 16:9.
Frame - Structure
rulib (METS has dtv_scan)
The temporal scanning structure of the video object.
Typical analog NSTC video is interlaced. HD and digital formats can be either interlaced or progressive, often indicated by the notation of the video resolution (480i is interlaced, 720p is progressive).
