Adjusting a content rendering system based on user occupancy

An integrated audio and video rendering device, comprising:

• a video rendering module configured to render a video portion of multimedia content;
• an audio rendering module configured to render an audio portion of the multimedia content and operable as a standalone audio reproduction device for playing audio without any correlated video;
• an occupancy sensor configured to detect user presence and user absence within an identified viewing space in which rendered video is viewable;
• and a controller configured to operate the integrated audio and video rendering device in a reduced power consumption mode in which the video rendering module is disabled and the audio rendering module operates as the standalone audio reproduction device even when a user is present in a space in which rendered video is viewable on the video rendering module, the identified viewing space including a video-only region, an audio-only region, and an audio and video region, the controller causing (a) video only to be played when the occupancy sensor only detects one or more users in the video-only region, (b) audio only to be played when the occupancy sensor only detects one or more users in the audio-only region, and (c) audio and video to be played when the occupancy sensor detects users in the audio and video region.
