Where to find "...on Hotel TVs, see Samsung D Forum B2B Developers."

Consumer Samsung TVs do not support automatic launching for applications installed through USB.

Hotel TVs, however, support this use case. For information on Hotel TVs, see Samsung D Forum B2B Developers.

I am trying to find the support information in regard to installing apps on Hotel variants of the TV.

Does anyone know where this is ?

I believe for this information you may need to go through the Smart TV Seller Office for support

I see that in my:
Version software : T-HKMFDEUC-1510.4
15TV_STANDARD2, Tizen 2.3, year 2015

Bottom item: Support → “How to use TV” (Home|Shop Usage)
