In block 404, the video-on-demand application module 202 communications with the video-on-demand server 104 to request video content. In some embodiments, the requested video content may correspond to an entire video-on-demand program selected by the viewer (e.g., a television show or a movie). In other embodiments, the requested video content may correspond to a segment of such video-on-demand program.
In block 406, the video-on-demand application module 202 plays the video content received from the video-on-demand server 104. In some embodiments, the video-on-demand application module 202 may stream the video content; that is, the video-on-demand application module 202 may play back the video content as the video content is received over the network. In other embodiments, the video-on-demand application module 202 may download and store the entire requested video content before playing back the video content. In some embodiments, the video-on-demand application module 202 may stream the video content and store the streamed video content in a buffer to account for network interruptions or slowdowns.
In block 408, the biometric data analysis module 206 receives and analyzes biometric data 208 indicative of the attention level of the viewer while the video content is being played. As discussed above, the biometric sensor(s) 132 provide raw biometric data 208 to the biometric data analysis module 206. The biometric data analysis module 206 analyzes and formats the raw biometric data 208 into a higher-level form indicative of the user's attention. The analyzed biometric data thus provides information on the user's attention level, engagement, and emotional response to the displayed video content. For example, given raw image capture data from the camera 134, the biometric data analysis module 206 may perform facial recognition analysis on the raw data. In this example, analyzed biometric data may include the number of faces detected and the spatial coordinates of various facial features. The biometric data analysis may be combined or recursive. Continuing the previous example, the analyzed biometric data may be further analyzed to determine facial expressions associated with the spatial coordinates of various facial features.
The biometric data analysis module 206 may perform distinct analysis on biometric data originating from different biometric sensors. For example, given audio data from the microphone 136, the biometric data analysis module 206 may perform speech recognition analysis to determine the contents of words spoken by the viewer. The biometric data analysis module 206 may also analyze the audio data to determine pitch, timbre, or other audio characteristics of the viewer's voice. The biometric data analysis module 206 may further analyze the audio characteristics of the viewer's voice to determine an associated emotional state of the viewer. In another example, given eye-tracking data from the eye-tracking sensor(s) 138, the biometric data analysis module 206 may determine the motion of the viewer's eyes, the dilation of the viewer's pupils, or the number of blinks. The biometric data analysis module 206 may further analyze the eye-tracking data to determine an emotional state of the viewer.
In block 410, the viewer attention determination module 204 determines the attention level of the viewer, using the analyzed biometric data produced by the biometric data analysis module 206. The viewer attention determination module 204 may determine viewer attention level by considering multiple types of biometric data, and each type of biometric data may contribute to the viewer attention level in different ways. The viewer attention level may be represented as a binary value (e.g., paying attention or not paying attention), a value from a set of attention levels (e.g., high, medium, and low attention level), or a numeric representation of viewer attention. For example, the viewer attention determination module 204 may determine a relatively high level of attention based on eye tracking data indicating the viewer is looking at the video content for long, uninterrupted time periods, based on the facial expression of the user indicating interest, or based on speech recognition data indicating the viewer is talking about the video content. Conversely, the viewer attention determination module 204 may determine a relatively low level of attention based on eye tracking data indicating the viewer is not watching the video content, the facial expression of the user indicating boredom, or the facial recognition data indicating the viewer is not present at the video device 102. In some embodiments, the viewer attention level may be determined by combining the various types of biometric data.
In block 412, the viewer attention determination module 204 determines whether the attention level of the viewer exceeds the threshold attention level or otherwise has some predetermined relationship to the threshold attention level (e.g., equals or exceeds, exceeds, etc.). The threshold attention level may be set at any relative level of attention desired for advertising purposes. In some embodiments, the threshold may be set relatively low. For example, the threshold may be exceeded if the viewer is simply present at the video device 102. In other embodiments, the threshold may be set relatively high. For example, the threshold may be exceeded only if the viewer is looking at the video device 102 and biometric data on the viewer's emotional state indicates interest. If the viewer attention level does not exceed the threshold, the method 400 loops back to block 404 and continues to request and play video content from the video-on-demand server 104. Note that in some embodiments, the video content may already be present at the video device 102, in which case the request to the video-on-demand server 104 is not necessary, and the method 400 may loop back to block 406.
Referring back to block 412, if the viewer attention level exceeds the threshold, the method 400 proceeds to block 414. In block 414, the video-on-demand application module 202 notifies the video-on-demand server 104 of an availability for an advertisement. Such notification indicates to the video-on-demand server 104 that the viewer attention level exceeds the threshold and, therefore, the viewer is likely paying attention to the video content. Upon receiving the notification, the video-on-demand server 104 determines a time for an advertisement break, which may be some time in the future.
In block 416, the video-on-demand application module 202 receives advertisement content from the video-on-demand server 104. As discussed above, some time may pass between the notification of advertisement availability discussed in block 414 and the actual delivery of advertisement content. In some embodiments (not illustrated), the video-on-demand application module 202 may receive a command to play advertisement content from the video-on-demand server 104, but the advertisement content may be received from another source, such as the advertisement server 106. In other embodiments, the advertisement content may be stored locally on the video device 102.
In block 418, the video-on-demand application module 202 plays the advertisement content. Such advertisement content is similar to video content: the advertisement content is video content that may be streamed or download in its entirety before being played. In the illustrative embodiment of
In block 420, the biometric data analysis module 206 receives biometric data 208 indicative of the attention level of the viewer while the advertisement content is being played. Block 420 is similar to block 408, and the above discussion of block 408 applies to block 420, except that in block 420, the biometric data analysis module 206 receives and analyzes data during playback of the advertisement content and not the video content.
In block 422, the viewer attention determination module 204 determines the attention level of the viewer, using the analyzed biometric data produced by the biometric data analysis module 206. Block 422 is similar to block 410, and the above discussion of block 410 applies to block 422, except that in block 422 the viewer attention level is determined during playback of the advertisement content, not the video content.
In block 424, the viewer attention determination module 204 the attention level of the viewer exceeds (or matches or exceeds) the threshold attention level. This determination is similar to the determination of block 412, and the same discussion applies, except that in block 424 the determination is made during playback of advertisement content. The threshold attention level of block 424 may be the same as in block 412, or may be different. If the viewer attention level is not above the threshold attention level, the method 400 proceeds to block 426. In block 426, the video-on-demand application module 202 pauses playback of the advertisement content. In some embodiments, instead of or in addition to pausing the advertisement content, the video-on-demand application module 202 may notify the video-on-demand server 104 that the viewer attention level is not above the threshold attention level. Such notification may allow the video-on-demand server 104 to record whether or not the advertisement content has been viewed, which may be used for tracking or billing purposes. After block 426, the method 400 loops back to block 420 to continue receiving biometric sensor data. Referring back to block 424, if the viewer attention level is above the threshold attention level, the method 400 proceeds to block 428.
In block 428, the video-on-demand application module 202 determines whether playback of the advertisement content is complete. If the playback is not complete, the method 400 loops back to block 418 to continue playing the advertisement content and receiving biometric data. If the playback is complete, the method 400 loops back to block 404 to continue requesting video-on-demand content.
The blocks 420 through 426 of method 400 describe generally a method ensuring that the viewer pays attention to advertisement content by pausing the advertisement content when the viewer attention level falls below a threshold attention level. In some embodiments, that behavior may not be desired. According, referring back to block 418, in some embodiments (not illustrated) the video-on-demand application module 202 may play back the entire advertisement content and then the method 400 may advance directly to block 428.

In block 504, the video content management module 302 serves the video content to the video device 102. As discussed above in connection with block 404, the video content may be streamed across the network 108 to the video device 102, or may be transferred in its entirety to the video device 102.
In block 506, the video content management module 302 receives a notification of an availability for an advertisement from the video device 102. Such notification may be received some time after the video-on-demand server 104 has begun serving video content to the video device 102. Such notification indicates that the attention level of the viewer exceeds the threshold attention level.
In response to receiving the notification from the video device 102, the method 500 advances to block 508, in which the advertisement break timing module 304 determines an advertisement break time. The advertisement break timing module 304 may employ several strategies for determining the advertisement break time. In block 510, the advertisement break timing module 304 uses the current time as the advertisement break time. Such strategy may be simple to implement, as no additional processing is necessary. However, much video content may not be amenable to advertisement breaks at essentially arbitrary times. In block 512, the advertisement break timing module 304 selects an advertisement break time from a set of pre-determined advertisement break times associated with the video content. For example, the pre-determined break times may correspond to advertisement breaks in traditional broadcast television programs. In other examples, the pre-determined break times may correspond to scene breaks in the video content. More generally, in other embodiments, the advertisement break timing module 304 may determine the advertisement break time as a function of the video content. For example, the advertisement break timing module 304 may analyze the video content to determine scene breaks.
In block 514, the advertisement content management module 306 serves the advertisement content to the video device 102 at the determined advertisement break time. In other embodiments (not illustrated), the advertisement content management module 306 commands the video device 102 to play back the selected advertisement content at the determined break time, which advertisement content was previously downloaded by the video device 102. The advertisement content management module 306 selects the advertisement content prior to serving the content to the video device 102. In some embodiments, the advertisement content management module 306 may select advertisement content from a pre-defined set of advertisement content. In block 516, in some embodiments the advertisement content management module 306 selects advertisement content based on the video content. For example, the advertisement content management module 306 may search for relevant advertisement content based on keywords extracted from the video content or associated metadata. In block 518, in some embodiments the advertisement content management module 306 forwards advertisement content from the advertisement server 106 to the video device 102. As discussed above, in some embodiments (not illustrated) the advertisement server 106 may deliver the advertisement content directly to the video device 102.
After the advertisement content has been served to the video device 102 in block 514, the method 500 loops back to block 504 to continue serving video content to the video device 102.
