A content protection system for satellite-based content delivery is provided, including a satellite content receiver. The satellite content receiver may include one or more processors and a non-transitory processor readable medium, and be in communication with a satellite antenna. The satellite content receiver may receive a first portion of streaming media content, transmitted by a content security host system using multicast communication. The first portion of the streaming media content may be stored, and later accessed in response to a user command. A second portion of the streaming media content including data missing from the first portion of the streaming media content may be identified. The second portion may be requested from the content security host system and received by the satellite content receiver. The first and second portions of the streaming media content may be combined to reconstruct the streaming media content, which may then be output.

Extended Digital Interface (XDI) provides systems, devices, connectors, signals, and methods to send 3D Vector and Motion based audio video serial digital signals through local systems or internet with significantly reduced bandwidth requirements and lower device costs, over longer cable runs. The XDI system has higher flexibility for connection topologies and scalability. The XDI system is much simpler to install employing the single coax cables and connectors, or internet, or Wi-Fi, which is simple and easy to work with, without introducing any signal quality losses or delays comparing to the current 2D Frame and Pixel based digital systems using multiple conductors like HDMI, DVI, DP or SDI when using the already compressed audio video content. The XDI system also provides solutions for integrating the uncompressed audio video content and Internet content into this system. These systems, devices, connectors and methods are collectively called “XDI” (Extended Digital Interface).

A system and method of operating a content distribution system includes generating a first request for first content by a first user device. Based on the first request for the first content, the first content is pre-positioned by communicating the first content to a downstream storage device closer to a second user device without communicating the first content to the first user device using the downstream storage device; and storing the first content in the downstream storage device as pre-positioned content. The method further includes communicating the first content to the second user device from the downstream storage device.

Techniques described herein include evaluation and management of device hardware, software, and network resources during streaming, downloading, or playback of video resources on client devices from remote locations. Certain aspects relate to evaluating the current resources available at a client device, such as memory, processing capacity, device battery status, network availability and/or network data quotas, in view of a video resource request. Based on the evaluation of the client device's resources, and estimations of the effects that video streaming/downloading and playback may have on the client device's resources, the client device may control, customize, and/or alter the retrieval or playback of requested video resources.

Various embodiments provide a system and methods for generating geographical models, determining geographical locations of set-top boxes using the geographical models, and modifying behavior of the set-top boxes based on their geographical locations. The set-top boxes determine their own geographical locations, regardless of whether the set-top boxes are capable of transmitting data to a content provider or include specialized equipment, such as a global positioning system, for determining geographical location.

A system and method of operating an over-the-air broadcast television system having spectrum capacity that has a first portion for linear broadcasting content in real time and a second portion corresponding to a dormant capacity. A content distribution network system receives digital content from a content storage system. A dormant capacity estimator estimates dormant capacity of the spectrum capacity. An intermediate storage device communicates a registration request signal to the content distribution network system using a reverse link. The content distribution network system communicates a registration acknowledgement signal to the intermediate storage device. The content distribution network system communicates the digital content to the intermediate storage device through the over-the-air broadcast television network system. The intermediate storage device stories the digital content therein. The content distribution network system communicates the digital content to a user device through a local link after storing the digital content.

A method and system of broadcasting includes determining an identified content for a broadcast to a broadcast group that may include a plurality of devices in a service area. The method also includes determining a priority for the identified content for the plurality of devices, determining radio conditions for each of the plurality of devices in the service area; and determining an available network capacity of a network for broadcasting in the service area; determining a spectral efficiency for the broadcast to achieve a performance target, said. The method also includes performance target based on the priority for the identified content, the radio conditions and the available network capacity. The method also includes broadcasting the identified content to the plurality of devices in the service area based on the spectral efficiency for the broadcast.

A method to provide configuration information from a broadcast network controller (BNC) to a decoder in an HTTP live streaming (HLS) network. The method includes the steps of: (a) initiating a configuration event notification by the BNC; (b) writing the configuration information as file; (c) announcing the configuration information as a SCTE-104 request; (d) translating the SCTE-104 request into an SCTE-35 message; (e) translating the SCTE-35 message into an HLS playlist file; and (f) retrieving the HLS playlist file at the decoder.

The present invention relates to a system installed in the digital TV receiver that provides the broadcaster with a secure method for ingesting alternative video and/or audio media, in place of passages of main video and/or audio, with a view to customizing the experience of the consumer identified during the digital video and/or audio consumer experience. The system is intended to provide the consumer with the best possible experience without any interruptions, loss of fluidity or loss of consistency in the playback of the alternative video and/or audio. The system provides a method for continuously verifying suitable conditions for playing back alternative video and audio.

Aspects of the subject disclosure may include, for example, a local server coupled to a plurality of client devices. The local server may receive encrypted content from one or more content sources and provide the content to the client devices. The local server and client devices may be part of a multi-client environment such as a hotel or conference center. The local server does not decrypt and re-encrypt content, thereby allowing the use of low cost equipment. Other embodiments are disclosed.
