devicetype 3 means Connected TV
A television with built-in internet apps, and the value most CTV targeting starts from.
When to send it
Send 3 when the ad will play on a smart TV, meaning a television that runs apps itself. CTV requests normally pair it with an app object, an App.bundle holding the store ID, and a Content object describing the program. In video requests it usually appears with Video.plcmt 1, since full-episode and live streams are instream.
Many CTV buyers target 3 and 7 together and treat the request as television inventory, with higher floors and creative rules suited to a TV player. Sellers disagree about streaming players plugged into a TV: some send 3, some 6 (Connected Device), some 7. Pick one per device class and keep it stable, because buyers learn each exchange's pattern. A TV screen in a bar or a waiting room that is sold as out-of-home inventory is 8, not 3.
