DISTRIBUTING DIGITAL CINEMA PACKAGE (DCP) OVER INTERNET
20230291960 · 2023-09-14 ·

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.

INTERNET PROTOCOL TELEVISION STREAMING METHODS AND APPARATUS
20220417612 · 2022-12-29 · ·

A system, method, and apparatus for Internet Protocol television streaming are disclosed. An example apparatus includes a plurality of remote access points. Each remote access point provides line termination for television programming received via a data feed from a television service provider. The respective remote access point is specifically assigned to an application operating on a client device for maintaining a one-to-one correspondence between the application and the respective data feed from the television service provider.

INTERACTIVE BROADCAST MEDIA CONTENT PROVIDER WITH DIRECT AUDIENCE INTERACTION
20220408165 · 2022-12-22 ·

A server system receives a digital media asset captured by a media capture device along with a dataset associated with the digital media asset. The server system generates a modified digital media asset by overlaying or embedding a glyph that encodes information pointing to the network location of the information page onto the digital media asset. A requesting device scans the glyph from the modified digital media asset and decodes from the glyph the information pointing to the network location. The information includes a certification that the digital media and the dataset associated with the digital media asset are unaltered. The requesting device may transmit communications to the server system to indicate approval or disapproval of the digital media asset, or to edit the digital media asset. The server system receives the communication and may modify the information to reflect comments, approvals, disapprovals, or edits.

Method and apparatus for providing broadcast service

A method for providing a broadcast service is provided. The method includes transmitting a user datagram protocol (UDP)/internet protocol (IP) packet including a first message, the first message containing information about a message to be signed and transmitted, and transmitting a moving picture experts group (MPEG) media transport protocol (MMTP) packet including a second message, the second message containing information about the broadcast service and information indicating whether the information about the broadcast service is signed. The first message includes an identifier of a key used to verify a signature of the message to be transmitted and signed and an identifier of a hash algorithm used to calculate a hash value of the message to be transmitted and signed.

Reception device, transmission device, and data processing method

The present technology relates to a reception device, a transmission device, and a data processing method that enable a flexible operation of a service using an application that accompanies content. A reception device includes: a reception unit that receives content; an acquisition unit that acquires an application in accordance with acquisition source information indicating an acquisition source of the application accompanying the content, the acquisition source information being included in control information transmitted together with the content; and a control unit that instantly starts the acquired application. The present technology can be applied to a television set capable of receiving digital broadcasts, for example.

Downloadable security and protection methods and apparatus

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.

Receiving apparatus, transmitting apparatus, and data processing method

There is provided an arrangement which is capable of reliably generating and transmitting viewing information with respect to contents received via a communication route other than terrestrial broadcasting waves. Contents in which a contents ID applicable to the generation of viewing information and viewing information-compatible data such as viewing information destination information or the like are recorded in an electronic watermark (WaterMark) or a sound data file are sent from a transmitting apparatus to a receiving apparatus. The receiving apparatus acquires the contents ID and the viewing information destination information, etc. from the electronic watermark (WM) or the sound data file, generates viewing information using the acquired data, and sends the generated viewing information to a designated address.

Electronic device for reproducing data and operation method thereof
11284150 · 2022-03-22 · ·

An electronic device and an operation method thereof, according to various embodiments, may: receive first data and second data compressed in a designated compression scheme; decompress the received first data and the received second data on the basis of at least the designated compression scheme; decrypt the decompressed second data; detect success of the decryption; and reproduce the decompressed first data and the decrypted second data.

SYSTEMS, METHODS, AND DEVICES FOR MEDIA CONTENT TAMPER PROTECTION AND DETECTION

Techniques for media content tamper protection and detection are described. In some embodiments, the protection method is performed at an encoder. The encoder obtains a first sequence of signatures within a group of pictures and a second sequence of signatures for audio frames corresponding to the group of pictures. The encoder then combines the first sequence of signatures and the second sequence of signatures to generate a combined signature, and the combined signature is then embedded in a transport stream for transmission to a client device. In some embodiments, the detection method is performed at a client device, where the client device, in response to detecting a first message in the transport stream, starts calculation of signatures for a group of pictures and corresponding audio frames. The client device then uses the calculated signatures to validate an expected signature for the group of pictures and the corresponding audio frames.
