context 1 means Video
The user is watching video content, on demand or live.
When to send it
Send 1 when the main content is video: a CTV program, a video page, a live stream, or an in-app player the user came to watch. It is the expected value with Video.plcmt 1 and with most CTV traffic.
Buyers use 1 to confirm a video environment, which supports instream pricing. It is confused with 5 when a video ad runs inside an article: the user is reading, so the context is text whatever the ad format. Sending 1 for an outstream unit on a text page misdescribes the inventory.
Example

"app": {
