Abstract: A media device, such as a set-top-box, may receive an indication that a video doorbell on the premises has been activated. The indication may activate an application associated with the video doorbell within the set-top-box. While the application is in use, a communication pathway may be created between the set-top-box and the video doorbell. For example, audio and/or video detected by the video doorbell may be sent, directly or indirectly, via the application, to the set-top-box for display on a television or other display. Furthermore, while the application is in use, user voice data for a user associated with the media device may be captured by a voice-enabled remote control and routed to the set-top-box or smart television and then to the video doorbell for output at the video doorbell.
