    摘要： Aspects of the subject disclosure may include, for example, a method including detecting attention by a user to a presentation displayed at an audiovisual presentation device. A real-time image of the user is obtained and stored local to the audiovisual presentation device. The image is analyzed to determine a presence in the image of a facial feature of the user; the device determines, based on the presence of the facial feature, whether the user is attentive to the presentation. When the user is not attentive to the presentation, a procedure is initiated at the audiovisual presentation device to reduce resource consumption by the device; the procedure can include continuing the presentation at a video quality level lower than at the beginning of the presentation, reducing a brightness of the display, continuing the presentation with only the audio portion, and discontinuing the presentation. Other embodiments are disclosed.

    摘要： Methods for obfuscating an image of a subject in a captured media are disclosed. For example, a method receives a communication from an endpoint device of a subject indicating that the image of the subject is to be obfuscated in a captured media. The communication may include a feature set associated with the subject, where the feature set contains facial features of the subject and motion information associated with the subject. The method then detects the image of the subject in the captured media. For example, the image of the subject is detected by matching the facial features of the subject to the image of the subject in the captured media and matching the motion information associated with the subject to a trajectory of the image of the subject in the captured media. The method then obfuscates the image of the subject in the captured media.

    摘要： A method executed by a processing system of an edge router deployed in a content distribution network includes receiving a request from an endpoint device for a first file, determining that a portion of the first file is not stored in a cache of the edge router, determining that the cache is at a capacity threshold, selecting a second file to evict from the cache, wherein the second file is one of a plurality of files stored in the cache, wherein each file of the plurality of files is scheduled to be evicted from the cache when a threshold period of time has passed since a last request for the each file was received by the edge router, and wherein the threshold period of time associated with the second file is scheduled to expire soonest among all of the plurality of files, and evicting the second file from the cache.
