Thumbnail images representative of recorded TV programs are generated and presented to aid a user in browsing the recorded TV programs. In one implementation, a temporary thumbnail image is generated when a TV program first starts recording. The temporary thumbnail is used to populate any user interface (UI) screens that reference the recoded TV program. Once the TV program has reached a threshold amount of recording (e.g., a prescribed duration of recording, or completion of the recording), a permanent thumbnail image is generated and associated with the TV program. The permanent thumbnail is then presented in any subsequent UI screens, replacing the temporary thumbnail. In another implementation, display of the thumbnail images in the UI screens may be further controlled by setting preferences, such as parental controls.

Thumbnail generation and presentation for recorded TV programs

Described herein is technology for, among other things, selecting a representative thumbnail from a video clip. The technology involves analyzing frames of the video clip to determine which frames are stable, the result of the analysis being a number of segments of stable frames. From the stable segments, a number of candidate segments are selected, where candidate segments are those segments determined to a degree of certainty to be program content. The representative thumbnail is then selected from among the frames of the candidate segments.

Embodiments described herein provide communication control features and functionality, but are not so limited. In an embodiment, a computing environment includes an access control component that can use a number of access states to control access to computing data and/or services. In one embodiment, a server computer can control access to data and/or services using a number of access states including, but not limited to: an allowed state, a blocked state, a device discovery state, and/or a quarantined state. Other embodiments are available.

Opaque quarantine and device discovery

Systems and methods for smart media content thumbnail extraction are described. In one aspect program metadata is generated from recorded video content. The program metadata includes one or more key-frames from one or more corresponding shots. An objectively representative key-frame is identified from among the key-frames as a function of shot duration and frequency of appearance of key-frame content across multiple shots. The objectively representative key-frame is an image frame representative of the recorded video content. A thumbnail is created from the objectively representative key-frame.

A method and system for generating a classifier to classify sub-objects of an object based on a relationship between sub-objects is provided. The classification system provides training sub-objects along with the actual classification of each training sub-object. The classification system may iteratively train sub-classifiers based on feature vectors representing the features of each sub-object, the actual classification of the sub-object, and a weight associated with the sub-object. After a sub-classifier is trained, the classification system classifies the training sub-objects using the trained sub-classifier. The classification system then adjusts the classifications based on relationships between training sub-objects. The classification system assigns a weight for the sub-classifier and weight for each sub-object based on the accuracy of the adjusted classifications.
