Abstract
Aspects of the present disclosure provide an entry presence detection mechanism for audio-video devices. According to aspects, devices are activated based on detecting presence of a subject in the vicinity of a device. Further, subject-specific content is output based on preconfigured preferences and/or historical usage. As described herein, the device is activated and subject-specific content or prompts are displayed without use of a remote control. This reduces the wait time to activate a device and connected devices. When a subject is determined to have left the vicinity for a configurable amount of time, the devices enter a low-power state. In aspects, the devices enter a low-power state in response to determining that no subjects remain in the vicinity of the device for a configurable amount of time.
