The described technology is generally directed towards validating content selection graphs for use in an in-memory content selection graph data store. When a content selection graph data is generated, the graph nodes can correspond to prebuilt response data. The response data for any of the nodes can be verified against rules based on the type of a node, for example, as well as based on client-specific information for types of clients. The overall validation process can validate the content selection graph for subsequent use, can result in errors or warnings being logged (which may or may not render the graph unusable, e.g., depending on severity), or can fail the content selection graph. If validated, the content selection graph can be used to rapidly return response data when content from the graph is requested.

Virtual site inspections to support clinical trials is disclosed. A frame and glasses subsystem has at least a global positioning system (GPS) and is associated with a first computing device at a physical site where an inspection is conducted. A session is opened in a web-based application on a second communication device that is in communication with, but that is physically remote from, the first computing device. Location tracking using GPS allows for a location of the frame and glasses subsystem to be continuously tracked. A script from the web-based application to the first computing device enables association with a video stream and locations within the physical site. The script enables responses to be provided from the first computing device at the locations. The locations, time stamps, video stream, the responses from the script, and a device identifier is provided immutably to the web-based application.

Methods and systems for calculating, storing, and allowing electronic searches for metadata associated with media titles. The metadata includes scores specific to each actor and each genre of a media title, where the scores indicate the degree to which an actor's performance in that title corresponds to a particular genre. Electronic searches for particular actors' performance in a specific genre thus return more accurate results that more correctly reflect how well the actors' performances reflect that genre.

Systems and methods for managing media mosaics are described. One embodiment provides a media mosaic management method in a media device. The method generates a mosaic filter based on a program selected from a first media mosaic. The mosaic filter is used to identify related programs for presentation in a second, customized media mosaic.

Methods and systems for managing data are disclosed. One method can comprise storing first data locally relative to a user device and storing second data remotely relative to the user device. The first data and the second data can relate to the same content. The method can also comprise generating a manifest comprising location information relating to the first data and the second data and receiving a request for transmission of one or more of the first data and the second data based upon the manifest.

An example method performed by a processing system includes retrieving a digital model of a media element from a database storing a plurality of media elements, wherein the media element is to be inserted into a scene of an audiovisual media, rendering the media element in the scene of the audiovisual media, based on the digital model of the media element and on metadata associated with the digital model to produce a rendered media element, wherein the metadata describes a characteristic of the media element and a limit on the characteristic, and inserting the rendered media element into the scene of the audiovisual media.

Systems and methods for matching videos to podcast episodes are provided. A data store comprising podcast episode identifiers is accessed. The podcast episode identifiers are associated with one or more podcast episode attributes. A video content item is identified. The video content item includes one or more video content item attributes. A matching podcast episode identifier that matches the video content item is determined based on the one or more podcast episode attributes and the one or more video content item attributes. A ranking of one of the video content item or the matching podcast episode identifier is caused to be adjusted to reflect the correspondence between the video content item and the matching podcast episode identifier. Information associated with the matching podcast episode identifier is provided to a first user device.

The described technology is generally directed towards coordinating the generation, validation and enabling of content selection graphs in an in-memory content selection graph data store. When a set of content selection graphs is requested, a coordinator starts the generation of the relevant graphs. Upon successful generation, the coordinator starts a validation of the generated graphs against rules for the nodes/response data in the graphs. If the generated graphs pass validation, the coordinator enables the graph set for use in an in-memory cache, whereby when a request to return content selection data is received, an active graph that corresponds to the request and the current time is accessed to obtain and return the response data as the requested content selection data.

Aspects of the invention are directed towards a system and a method for streaming video. One or more embodiments of the invention describe a method comprising steps of transmitting a request to a server by a user device for streaming a video and receiving one or more video segments of the video from the server. One or more embodiments of the invention further describe creating object uniform resource locators (URLs) for each of the one or more video segments and transmitting the created object URLs to the server, wherein an in-memory playlist is created on the server including the object URLs of the one or more video segments. The user device receives the playlist URL of the in-memory playlist from the server and streams the one or more video segments of the video at the user device by using the playlist URL.

A method and a related apparatus for providing a guide media presentation in media streaming are disclosed. The method include obtaining, by a client, a media presentation description (MPD) of a guide media presentation, where the MPD of the guide media presentation describes N guide units included in the guide media presentation, obtaining K guide units in the N guide units according to the MPD of the guide media presentation, and presenting the K guide units, where each guide unit in the K guide units points to one main media presentation, and presentation quality of a main media presentation to which a guide unit i in the K guide units points is higher than presentation quality of the guide unit i. Solutions support a video guide in an Hypertext Transfer Protocol (HTTP)-based media streaming service scenario and improve user experience.
