  • the audio/ video content may include audio only, video only, still images only, or any combination thereof.
  • the audio/video content may be provided by a cable or satellite service provider, by a web-based service, by a digital video recorder device coupled to the set-top box device, by a digital video recorder feature that is embedded or integrated in the set-top box device, or by other suitable means.
  • this embodiment assumes that the user has the ability to configure, initialize, or otherwise activate the sleep monitor function (task 304) of the set-top box device.
  • the sleep monitor feature must be activated for it to be effective.
  • the sleep monitor feature could be active by default, or it could always be active and running in the background.
  • the process 300 operates the sensors to obtain or collect the corresponding sensor data at the set- top box device (task 306).
  • a sensor could provide its sensor data to the set-top box device using a tangible data communication link and/or using a wireless data communication link.
  • the sensor data can be processed, analyzed, or otherwise handled in an appropriate manner (task 308).
  • most if not all of the sensor data processing is performed locally at the set-top box device (for example, sensor data processing could be executed by the sensor data processing module 212 shown in FIG. 2).
  • the sensor data processing could be performed by a system, device, or component other than the set-top box device.
  • the sensor data processing could be distributed between the set-top box device and any number of other systems, devices, or components that are remote from the set-top box device.
  • some or all of the sensor data processing might be performed by a network-based service, by a server system, at a headend facility, at a central control center, or the like.
  • the process determines whether the user is likely to be asleep (query task 312), based upon the analysis of the received sensor data.
  • this determination can be influenced by the analysis of sensor data from any one sensor, or by the combined analysis of sensor data from any plurality of sensors. In preferred embodiments, this determination is influenced and dictated by the analysis of all available sensor data. Use of all sensor data is desirable for the sake of accuracy and to avoid "false positive" results.
  • query task 312 determines that the user is not asleep, then the process 300 may exit or it may be re-entered at an appropriate point, such as task 306. If, however, query task 312 determines that the user is likely to be asleep, then the process 300 can proceed to a task 314.
  • the process 300 can arrive at the conclusion that the user is likely to be asleep in any number of different ways. For example, the physiological condition might indicate that the user is likely to be asleep when the user motion data indicates little to no user motion over a particular period of time. In other words, if little to no user movement has been detected during designated period of time (e.g., one minute, five minutes, an hour, etc.), then it might be reasonable for the system to assume that the user has fallen asleep.
  • designated period of time e.g., one minute, five minutes, an hour, etc.
  • the physiological condition might indicate that the user is likely to be asleep when the user heart rate data indicates a drop in heart rate of the user.
  • the system could employ an appropriate threshold value such that a lower heart rate will not influence the sleep determination unless it has fallen by at least a threshold amount during a specified period of time.
  • the physiological condition might indicate that the user is likely to be asleep when user sound data or user respiration data indicates a drop in the respiration rate of the user.
  • the system could employ an appropriate threshold value such that a lower respiration rate will not influence the sleep determination unless it has fallen by at least a threshold amount during a specified period of time.
  • Sound data could also be used to determine whether the user is snoring.
  • the physiological condition might indicate that the user is likely to be asleep when the user sound data is indicative of snoring.
  • the process 300 continues by controlling and/or initiating changes to certain presentation parameters, display characteristics, or content being presented to the user (task 314).
  • the set-top box device could control at least one presentation parameter associated with the current audio/video content when the physiological condition indicates that the user is likely to be asleep.
  • the set-top box device could initiate at least one change to presentation characteristics associated with the current audio/video content. More specifically, the set-top box device could initiate an adjustment of at least one setting of the presentation device that is currently being used to present the audio/video content to the user.
  • the set-top box device could select new audio/video content that is appropriate for a sleeping state of the user, and thereafter initiate the presentation of the new audio/video content.
  • the new audio/video content might be preselected by the user, or it could be automatically chosen by the set-top box device using a content tagging, labeling, or categorization scheme. For example, if the user has fallen asleep, then it may be appropriate to change the audio/video content from an action or adventure movie to an ambient background music score, a classical music concert, or the like.
  • the particular manner in which the system is automatically adjusted or modified may differ from one embodiment to another, and it may vary depending upon the analysis of the sensor data. For example, in certain scenarios it may be appropriate to adjust a brightness setting of a display being used to present the audio/video content to the user. Typically, this will result in a lower brightness setting because most people prefer to sleep in a dark environment (although a higher brightness setting could be configured if so desired). As another example, it may be appropriate to adjust a volume setting of the presentation device currently being used to present the audio/video content to the user. Typically, this will result in a lower volume setting because most people prefer to sleep in a quiet environment, and to reduce the likelihood that the user will be awakened by loud sounds (although a higher volume setting could be configured if so desired).
  • the set-top box device initiates a standby or power-down state of the presentation device currently being used to present the audio/video content to the user.
  • the presentation device can be shut down or placed into a standby mode. In typical implementations, this will effectively blank the display and mute the sound of the presentation device. Moreover, this has the additional benefit of conserving energy.
  • the set-top box device could initiate a standby or power-down state of itself when query task 312 determines that the user is likely to be asleep. Again, this will typically result in blanking of the display and muting of the sound.
  • the system includes a recording device, such as a digital video recorder
  • the recording device can be activated to record the audio/video content when query task 312 determines that the user is likely to be asleep.
  • query task 312 determines that the user is likely to be asleep.
  • the audio/video content could be recorded in this manner even if the presentation device is shut down or placed into standby mode, and/or if the set-top box device is shut down or placed into its standby mode.
  • system described here could also be suitably configured to continue monitoring the state or condition of the user to determine when the user is no longer sleeping. Similar sensor data processing can be performed to detect when the user wakes up and, in response thereto, one or more controls, command, adjustments, changes, or modifications can be initiated or executed as desired to account for the user's wakened state. For example, the volume and brightness of the presentation device can be returned to their previous levels, the user could be prompted to view any recorded content, etc.
