Systems and methods are provided for, in response to determining that an election to opt into a privacy policy has not been received from the user (or that an election to opt out of the privacy policy has been received from the user) using limited functionality of a data provider system to select, from a set of candidate data items and using a particular selection criterion (not based on personal information of the user), data items to be transmitted. System and methods may be further provided for, in response to determining that an election to opt into the privacy policy has been received (or that an election to opt out of the privacy policy has not been received), using full functionality search of the data provider system to select data items from the set of candidate data items based at least in part on the accessed personal information.

Embodiments of the present invention enable the extraction, classification, storage, and supplementation of presentation video. A media system receives a video signal carrying presentation video. The media system processes the video signal and generates images for slides of the presentation. The media system then extracts text from the images and uses the text and other characteristics to classify the images and store them in a database. Additionally, the system enables viewers of the presentation to provide feedback on the presentation, which can be used to supplement the presentation.

Mechanisms are provided for retrieving and presenting related content using text stream data feeds. Text stream data feeds such as caption information associated with media content or conversations associated with social networking applications are aggregated and used to retrieve related media content, text documents, and advertisements. Text stream data feeds that a user is exposed to may indicate that the user is interested or at least primed for particular types of related content. In particular examples, an inverse vector space search engine is used to determine particular pieces of related content and categories of interest. Post filtering may also be applied to the results.

A system, method, and computer program product for automatically analyzing multimedia data are disclosed. Embodiments receive multimedia data, detect portions having specified features, and output a corresponding subset of the multimedia data. Content features from downloaded or streaming movies or video clips are identified as a human probably would do, but in essentially real time. Embodiments then generate an index or menu based on individual consumer preferences. Consumers can peruse the index, or produce customized trailers, or edit and tag content with metadata as desired. The tool can categorize and cluster content by feature, to assemble a library of scenes or scene clusters according to user-selected criteria.

Disclosed are various embodiments for synchronizing application state information across devices. More specifically, embodiments of the disclosure are related to facilitating idempotency of application state information. Idempotency is maintained by using a timestamp embedded within application state information and/or by determining that the application state information is associated with an accumulating value.

Techniques described herein enable searching for multimedia content and for downloading or scheduling the recording of the multimedia content. The multimedia content may have been previously stored on one or more databases. The client device may download or schedule the recording of multimedia content in one step, for example, in one touch. When desired multimedia content is not available, the multimedia content is added to the client device's wish list. When the client device's does not have a wish list, the client device's wish list may be created on the spot. During the scheduling of the recording, a tag associated with the multimedia content is checked to determine whether the multimedia content is live or delayed. When the tag indicates the multimedia content is live or delayed, the client device prompts with a suggestion to add extra time to the end of the recording of the multimedia content.
