摘要： Techniques for selecting TV user interface (UI) transition characteristics are described. In accordance with various embodiments, a transition characteristics selection method is performed at a device (e.g., a cloud UI engine on a server) with one or more processors and a non-transitory memory. The UI engine receives a request for transitioning from a first screen to a second screen on a client device while in a real-time content presentation mode. In response to receiving the request and while in the real-time content presentation mode, the UI engine obtains one or more presentation conditions of the client device and selects one or more transition characteristics for transitioning from the first screen to the second screen based on costs associated with the one or more transition characteristics and the one or more presentation conditions.

摘要： Techniques for a smartphone-based conditional access (CA) system are described. In some embodiments, a headend in the CA system obtains a security profile associated with a pair of receiving devices used by a user, e.g., a first device (e.g., a smartphone) and a second device (e.g., a set-top-box or a TV). The headend dynamically regulates user access to requested media content during each entitlement period by assigning and distributing separate keys to the first and second device based on the security profile. The headend also uses the distributed keys to protect the media content before broadcasting. On the receiving end, one receiving device receives the media content and determines whether it is decryptable by the device. If decryptable, the receiving device (e.g., the set-top-box/TV) decrypts the media content using the keys assigned by the headend. Otherwise, the receiving device forwards the media content to the pairing device for decryption.

摘要： Techniques for publishing key pictures at a server and using the key picture information for operations on a client device are described herein. In accordance with various embodiments, the server creates an intermediate unit including key picture(s) from media content. The server then generates map(s) specifying for each key picture, a type, properties, and an association to the intermediate unit. The server also packages the intermediate unit into key picture unit(s) according to the map(s). The client device obtains a manifest for the media content referencing the key picture(s) and the type of each key picture. Upon receiving a request to perform operation(s) on a respective key picture, the client device obtains a corresponding key picture unit and parses the manifest to determine a respective type. Based on the respective type matches a criterion, the client device performs the operation(s) on the key picture unit.

摘要： Techniques for embedding secure feature selection at content delivery network (CDN) edge are described. In accordance with various embodiments, server(s) in a cloud receive from a client device a request for a media URL associated with a media asset. The server(s) identify feature state(s) associated with the client device and the media asset on a CDN edge node hosting the media asset. The server(s) then selectively generate a unique token or a common token specifying the feature state(s) before sending the media URL including the unique token or the common token to the client device. Upon receiving the media URL, the CDN edge node in an edge node with features deployed, determines whether the media URL causes a cache miss. Upon determining that the media URL causes the cache miss, the CDN edge node changes a feature state of a feature, applies the feature, and provides the media asset.

摘要： Techniques for delivering targeted content to a client device (e.g., a set-top-box (STB)) with a tuner, one or more controllers, and a non-transitory memory are described. In accordance with various embodiments, the client device obtains streaming media content in a stream and detects a plurality of transport packets under a packet identifier (PID) in the stream, where the plurality of transport packets is associated with a targeted content delivery service. The client device further identifies metadata corresponding to targeted content of the targeted content delivery service in the plurality transport packets under the PID. The client device then selects a list of targeted content identifiers for the client device based on the metadata and a profile of the client device and downloads the targeted content according to the list of targeted content identifiers.

摘要： A method is performed at a network device including a plurality of network interfaces. The method includes obtaining a first source adaptive bitrate (ABR) asset and a second source ABR asset. The method includes encoding the first source ABR asset in order to generate a first plurality of video representations, and encoding the second source ABR asset in order to generate a second plurality of video representations. The method includes providing, to a first client device, a first one of the first plurality of video representations. The method includes, in response to detecting satisfaction of a source change condition with respect to the first client device, providing, to the first client device, a first one of the second plurality of video representations, and ceasing to provide the first one of the first plurality of video representations to the first client device.

摘要： A method of splitting a data stream into a set of data segments may include receiving the data stream, wherein the data stream may include data packets; selecting a segment time period and a time domain; subdividing the time domain into a set of time blocks, each one of the set of time blocks having a duration of the segment time period; identifying a set of starting data packets corresponding to the set of time blocks; identifying a set of finishing data packets corresponding to the set of starting data packets; identifying a last one of the set of finishing data packets being a last data packet of a last one of the set of time blocks; and identifying the set of data segments based on the corresponding set of starting data packets and the corresponding set of finishing data packets.

摘要： Techniques for targeting media content items for weakly connected devices are described. In some embodiments, a model building method in preparation for approximated personalization is performed at a server. The server uses data from fully connected devices to build a full model, which classifies profiles into clusters and tags targeted content with content rankings. The server also builds device models that approximate the full model. The server then sends the device models to user devices for targeted content selection. In some embodiments, a content selection method for approximated personalization is performed at a user device. The user device receives parameters of a device model trained by a server. The user device then executes the device model using local user data to assign a profile to a cluster and selects targeted content for the profile based on the cluster assignment and the rankings of the targeted content.
