Methods and apparatus for distributing content using a spectrum generation device. In one embodiment, digital content is received via a time-multiplexed network transport (such as Gigabit Ethernet), and converted to frequency channels suitable for transmission over a content distribution (e.g., Hybrid Fiber Coaxial (HFC)) network. In one variant, the conversion is performed using digital domain processing performed by a full spectrum generation device. Additionally, methods and apparatus for selectively adding, removing, and/or changing digital content from the full spectrum device are also disclosed. Various aspects of the present invention enable physical (infrastructure) consolidation, and software-implemented remote management of content distribution.

A method and apparatus for controlling a group of the client devices to switch at least one client device of the group of client devices from a first conditional access system to a second conditional access system is disclosed. In one embodiment, the method comprises generating a group identifier identifying the group of the client devices, transmitting a first client device signaling message having the group identifier only to each client device of the identified group of the client devices, and transmitting a second client device signaling message to the plurality of client devices, the second client device signaling message comprising the group identifier and signaling each client device having the group identifier stored in the non-volatile memory to switch from the first system client to the second system client.

A method and a device for processing a multimedia file are provided. In some embodiments, for a multimedia file to be processed, payload data in the multimedia file is acquired, and the payload data includes multi-frame data forming the multimedia file. Some pieces of frame data are selected from the payload data as frame data to be encrypted, and the frame data to be encrypted is encrypted. New payload data is formed by the encrypted frame data and unencrypted frame data, and the new payload data is encoded to obtain an encoded multimedia file. Therefore, the protection of the copyrights of the multimedia file is achieved.

Provided is a relay device for transferring a protocol data unit (PDU) transmitted from a server device to a terminal device, receiving content information that pertains to content stored in the PDU, and controlling a transfer in the PDU transfer step on the basis of the content information. The terminal device receives, via the relay device, the PDU transmitted from the server device, and transmits the content information that pertains to the content stored in the PDU to the relay device.

A configuration is realized in which block encryption MMT format data is reproduced by applying a time stamp. An MMT format stream file and a reproduction control information file are generated and recorded in a medium. The stream file includes encryption block data to which an encryption key generated by using an additional header in which copy control information of a block unit is stored, as a seed, is applied, and the additional header. Position identification information capable of determining a position of reproduction data, a position of the seed to be applied to decoding of the reproduction data, a position of the time stamp, and a position of the seed to be applied to decoding of the time stamp is recorded in the reproduction control information file. Data decoding, and reproduction to which the time stamp is applied are performed by using recording information.

A method and system for managing adaptive bitrate video streaming. The method including: retrieving raw data associated with a video stream traffic flow; determining at least one video chunk from the raw data of video stream traffic flow; determining parameters associated with the video chunk; determining a bitrate factor based on the parameters; determining a Quality of Experience (QoE) score based on the bitrate factor; and providing a traffic action based on the QoE score. The system including: an input module configured to retrieve raw data; an analysis module configured to determine at least one video chunk from the raw data and determine parameters associated with the video chunk and a bitrate factor based on the parameters; a QoE module configured to determine a QoE score based on the bitrate factor; and an output module configured to provide a traffic action based on the QoE score.

Methods, systems, and machine-readable media for adapting content composites to device operations of an endpoint media device are disclosed. Blockchain data associated with a blockchain address may be processed by one or more processing devices. The blockchain data and/or the blockchain address may be mapped by the one or more processing devices to a first endpoint media device. Based at least in part on the blockchain data, a first content composite may be identified by one or more processing devices for delivery from a content provider system via one or more networks to the first endpoint media device. Transmission of the first content composite may be caused where, consequent to delivery of the first content composite to the first endpoint media device, the first endpoint media device or a second endpoint media device performs at least one operation relating to the first content composite.

A method and apparatus for controlling a group of the client devices to switch at least one client device of the group of client devices from a first conditional access system to a second conditional access system is disclosed. In one embodiment, the method comprises generating a group identifier identifying the group of the client devices, transmitting a first client device signaling message having the group identifier only to each client device of the identified group of client devices, the group identifier for storage in each client device of the identified group of client devices in non-volatile memory, and transmitting a second client device signaling message to plurality of client devices, the second client device message comprising the group identifier and signaling a switch of each of the identified group of client devices from the first conditional access system to the second conditional access system.

A method includes generating a first media file that includes a plurality of first media file segments, generating a second media file as a copy of the first media file, the second media file includes a plurality of second media file segments, embedding a first watermark with the plurality of first media file segments, embedding at least one second watermark with the plurality of second media file segments, generating a manifest file based on a portion of the plurality of first media file segments and a portion of the plurality of second media file segments, the manifest file including a plurality of addresses each referencing a media file segment, and encrypting each of plurality of addresses.
