Abstract: Disclosed are systems and methods to deliver location restricted content to devices that do not have a location component, such as a Global Positioning System component. A location aware device may send to a content delivery service, location information determined by a location component of the location aware device and receive, from the content delivery service, an encrypted access token. The location aware device may then send the access token to a non-location aware device that is on a same local area network as the location aware device. The non-location aware device may provide the access token to the content delivery service along with a request for location restricted content. The content delivery service may use the access token provided by the non-location aware device to verify that the non-location aware device is within a defined area for which the requested location restricted content is allowed for presentation.

Abstract: An apparatus includes a network interface and a processor. The network interface receives event data that identifies a content ID and a message authentication code. The content ID identifies a content within a webcast or a virtual event. The processor generates a content hash, at least in part based on the content ID. The network interface transmits a content request and receives the content. The content request identifies the content hash and the message authentication code.

An exemplary embodiment receives a first content stream associated with a currently presented channel at a first tuner, determines an anticipated channel based upon the currently presented channel and a historical channel surfing pattern, receives a second content stream associated with the anticipated channel at a second tuner, detects an initiation of a channel surfing activity, and presents at least a video portion of the second content stream associated with the anticipated channel in response to detecting the initiation of the channel surfing activity.

Abstract: Techniques for trigger based digital content caching are described to automatically cache digital content on a client device based on a likelihood that the client device will access the digital content. A cache system, for instance, monitors an interaction of a first client device with digital content that is maintained as part of a digital service by a service provider system. Based on the monitored interaction, the cache system detects a trigger event that indicates a likelihood of interaction by a second client device to edit the digital content. Responsive to detection of the trigger event, the cache system is operable to initiate caching of the digital content on the second client device automatically and without user intervention.

Abstract: Methods and systems for content optimization are described. A computing device may determine a predictability score that indicates a probability that a device will access a first content item. The computing device may send a second content item associated with the first content item. The second content item may be based on the predictability score, and the predictability score may be modified. Additional content consumption and/or recommendations may be adjusted based on the predictability score.

Abstract: Systems and methods for adaptively adjusting a slew rate of a dejitter buffer in a remote device in a distributed access architecture. The slew rate may be adjusted based on measurements of a fullness state of a buffer made over time. The measurements may be used to calculate a frequency offset value between the rate at which data leaves the buffer relative to the rate at which data enters the buffer and/or used to calculate a current working depth of the buffer. The adaptive slew rate adjustments may be based on the frequency offset value and/or the current working depth.

The content ID identifies a content within a webcast or a virtual event. The processor generates a content hash, at least in part based on the content ID. The network interface transmits a content request and receives the content. The content request identifies the content hash and the message authentication code.

Abstract: Transmit-Receive Longitudinal (TRL) probes can be used for the inspection of noisy material, such as austenitic materials. By using various techniques, an inspection area is not constrained by a wedge design of an ultrasonic probe and the benefits of using a linear probe array (rather than a matrix) are maintained. Volumetric or TFM-like imaging on austenitic materials using a linear transmit array and a linear receive array that are out of plane with one another (a TRL configuration) and not in the main imaging place can simplify the inspection and analysis of such materials. For each scan position, an ultrasound probe can acquire acoustic imaging data. Then, a processor can then combine acquisitions from adjacent scan positions to create an imaging result using synthetic aperture focusing technique (SAFT) principles to recreate a focalization in a passive axis of the probe.

Abstract: Techniques for migrating live broadcast streams from one data center to another data center are described herein. A data center from a plurality of data centers may be determined to transfer live streaming video content from a first data center to the data center. A separate live streaming session for each live streaming session being broadcast by the first data center may be generated by communicating with an ingest service server that receives media content used to generate each separate live streaming session and the live streaming session. Each separate live streaming session may be routed to the candidate data center. A determination that each separate live streaming session of the candidate data center is synchronized with each live streaming session of the first data center may be made. An update to a mapping of IP addresses to redirect requests from the first data center to the candidate data center.

Abstract: Systems and methods are described for delivering regional content for a lineup over a national network. A content provider may select a particular regional broadcast for inclusion in a regional service lineup. The content provider may be able to broadcast multiple, or even all, services nationally. At regional distribution centers, a multiplexer may select only those services that are desired for the region in response to in-stream signals. In some instances, a single region-specific version of a given service may be selected from multiple versions broadcasted nationally. The regional lineup, including the selected services, can then be multiplexed and transmitted to customers throughout the region.
