Abstract: A system and method for inserting secondary content, e.g., advertisement content, graphics, images, etc., in a 360-degree immersive video environment. When a request is received from a client device for playing a video asset, a plurality of video tiles of the video asset are selected to be assembled as a video frame for delivery to the client device.

Abstract: Providing bitrate control for delivering media content to a plurality of virtual display (VD) screens presented in a virtual reality (VR) environment effectuated by a VR device of a subscriber based on detecting a movement in a point of view with respect the VD screens' placement within the VR environment.
