Abstract: One embodiment of the invention sets forth a mechanism for encoding video streams associated with the same digital content such that switch points staggered across two video streams occur at every offset temporal distance. The offset temporal distance is less than the distance between two consecutive key frames in a given video stream. This enables a content player to switch to a video stream having a playback quality up or down one level from a current video stream at the offset temporal distance from the most recently played key frame. In effect, the content player does not wait the entire key frame temporal distance before switching.

Abstract: An online system receives a video-presentation request from a third party system. The video-presentation request comprises a video and a target audience specification for the video. The online system selects a plurality of users as the target audience of the video based on the target audience specification. From the target audience, the online system generates a sample subset of users and determines a sampled video reach count for the subset of users. A sample user who, as determined by the online system, would have viewed the view for at least a threshold duration, is included in the sampled video view count. The online system estimates a total video reach count for target audience by extrapolating the sampled video reach count for the subset of users to the target audience. The total video reach count can be used to determine a parameter for presenting the video on an online system.

Abstract: Convenience in a decoding process on a receiver side for when a predetermined number of high-quality-format image data is transmitted together with basic-format image data is achieved. A base stream including, as an access unit, encoded image data for each picture of basic-format image data, and a predetermined number of enhanced streams, each including, as an access unit, encoded image data for each picture of high-quality-format image data are generated. Here, a predictive coding process is performed on image data in high-quality format by referring to the image data in basic format or image data in another high-quality format, by which an enhanced stream is generated. Then, information indicating decoding order is added to each access unit of the enhanced streams. A container in a predetermined format that includes the base stream and the predetermined number of enhanced streams is transmitted.

Abstract: Embodiments presented herein provide systems and methods for unifying data that is stored in disparate namespaces. A system described herein receives an electronic request for data associated with an entity. The electronic request includes a first identifier of the entity in a first namespace. The system includes a digital relation that maps the first identifier to a primary identifier. The system determines additional identifiers that map to the primary identifier in the relation. The additional identifiers are associated with the entity in respective additional namespaces. The system retrieves a consolidated set of profile data associated with the primary identifier, including attributes of the entity within the first namespace and attributes of the entity within the additional namespaces. The system generates an electronic response to the electronic request based on the consolidated set of profile data and sends the response to an application that submitted the electronic request.

Abstract: A set-top box can provide a program for display to a video device that can be provided to the set-top box using a first signal in a first format, which can be a satellite or cable feed. The set-top box can receive a highlight notification from a content server for a highlight available to be provided for viewing during the program and, in response, can provide an alert associated with the highlight to the video device for display. The set-top box can receive an indication that the alert has been selected and, in response, can access the highlight and provide the highlight to the video device for display. The highlight can be streamed to the set-top box using a second signal in a second format, which can be a video streamed as web content in an Internet video format, and can be removed from display upon completion of the highlight.

Abstract: Methods and apparatuses are described for automatic authentication switching in online chat sessions. A server receives a request to establish an online chat session from a first client device, including authentication credentials associated with the first client device. The server establishes an online chat session between the first client device and a second client device via a first authenticated communications channel. The server transmits one or more chat messages between the first client device and the second client device using the first authenticated communications channel. The first client device determines that the online chat session has lost authentication. The first client device automatically switches the online chat session to a second unauthenticated communications channel. The server maintains the established online chat session between the first client device and the second client device via the second unauthenticated communications channel.

Abstract: A graphical user interface is disclosed which achieves an easy search for a desired item. When an operation inputting section accepts a selective operation input for selection of one of plural processing functions, plural representation images individually representing plural processing object items of the processing function are displayed in an array along one direction of a display screen such that one of the representation images can be selected as a noticed representation image by an inputting operation through the operation inputting section. A decision section decides whether or not plural processing object items of the selected processing function are divided in a plurality of groups. If the processing object items are divided in groups, then the group name of the group to which the processing object item of the noticed representation image belongs is displayed in the proximity of the noticed representation image.

A time shifted viewing code is calculated based on the difference. The time shifted viewing code is transmitted to a media monitor that transmitted the media identifier, the time shifted viewing code to be reported when the media monitor reports monitoring information.

Abstract: A dynamic runtime reconfigurable server its operational logic as it performs tasks for different customers at different times based on different configurations defined by the customers. The embodiments reduce resource overhead associated with reconfiguring and loading the different customer configurations into server memory at runtime. The server selectively loads different customer configurations from storage into server memory as the configurations are accessed in response to received client requests. The server also selectively preloads configurations into memory at periodic server restarts based on configurations accessed during the interval prior to each restart. The restart allows the server to remove old configurations from memory and maintain the most recently accessed ones. Restarting is also performed without interrupting server operation in responding to user requests.
