摘要： Disclosed are systems, methods, and non-transitory computer-readable media for distributed DCP over internet. A client-side digital content delivery device receives a digital cinema package (DCP) for a digital movie from a remote digital content delivery system. The DCP includes a unique digital watermark applied by the content delivery system. In response to receiving an input to cause playback of the digital movie, the client-side digital content delivery device compares a unique device identifier for a display device paired to the client-side digital content delivery device to an authorized unique identifier. If the unique device identifier matches the authorized unique identifier, the client-side digital content delivery device uses the DCP to causes presentation of the digital movie by the display device paired to the client-side digital content delivery device.

摘要： Methods and apparatus for control of data and content protection mechanisms across a network using a download delivery paradigm. In one embodiment, conditional access (CA), digital rights management (DRM), and trusted domain (TD) security policies are delivered, configured and enforced with respect to consumer premises equipment (CPE) within a cable television network. A trusted domain is established within the user's premises within which content access, distribution, and reproduction can be controlled remotely by the network operator. The content may be distributed to secure or non-secure “output” domains consistent with the security policies enforced by secure CA, DRM, and TD clients running within the trusted domain. Legacy and retail CPE models are also supported. A network security architecture comprising an authentication proxy (AP), provisioning system (MPS), and conditional access system (CAS) is also disclosed, which can interface with a trusted authority (TA) for cryptographic element management and CPE/user device authentication.

摘要： A multicast content delivery system can use both multicast and unicast streams to efficiently use available bandwidth to deliver content. Available multicast content can be identified to gateways serving consumption devices, and the gateways can receive requests for unicast content deliver, but honor the requests with multicast group sessions.

摘要： An attention marker can be transmitted to a radio receiver using an out-of-band transmission. One or more watermarks can be inserted in an over-the-air broadcast. A radio can include a tuner for receiving the over-the-air broadcast; an out-of-band receiver to receive substitute media content and the attention marker; memory to store the substitute media content; a user interface to play out media content to a user; and processing circuitry implementing multiple modules such as a marker detection module, a watermark detection module, and a local playout control module. The marker detection module can detect the out-of-band attention marker, and in response to detection of the attention marker trigger or schedule activation/deactivation of the watermark detection module. If the watermark detection module detects a watermark, the substitute content stored in the memory can be played out in place of the broadcast content.

摘要： A method and system of content management for datacasting. Such a system may have, as its core, a dashboard system for managing data feeds. A dashboard system may receive data feeds from one or more associated devices, such as the hardware devices of first responders or other public safety officers, and may aggregate and prioritize them. The dashboard system may then manage, prioritize and encrypt the video, files and other data in preparation for broadcast over the television or satellite transmitter, via, for example, a television broadcasting station, and may then broadcast the video, files, or other data to a plurality of users. Alerts and notifications may be created, files attached and links to video streams distributed over this same broadcast network. The broadcasting system may be able to send multiple streams of content simultaneously, may be able to target specific users to be broadcast to, and may be able to incorporate data from public data sources, such as public security cameras.
