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.

Embodiments of the present disclosure provide network live-broadcasting methods and devices. The method can include: obtaining live-broadcasting data from a server side; obtaining service data from the server side; determining whether the obtained live-broadcasting data contains key information, wherein the key information is inserted by a live-broadcasting side in the live-broadcasting data when predetermined content corresponding to the service data is included in the live-broadcasting data; and outputting, in response to receiving the key information, the service data on a playing interface of the live-broadcasting data, so that the service data is output synchronously with the predetermined content.

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.

A system for maximizing storage of encrypted content in a storage system includes one or more processors; and a storage medium storing instructions. When executed, the instructions may configure the one or more processors to: receive, from a first client device, a first data structure encrypted commutatively with a first key and a common key, the receiving system lacking access to the common key; receive the first key and a first segment identifier; receive, from a second client device, a second data structure encrypted commutatively with a second key and the common key; receive a second segment identifier; using the first key, partially decrypt the first data structure; storing the partially decrypted first data structure; and selectively storing a copy of the second data structure based on whether content of the first data structure corresponds to content of the second data structure.

A unified system of programming communication. The system encompasses the prior art (television, radio, broadcast hardcopy, computer communications, etc.) and new user specific mass media. Within the unified system, parallel processing computer systems, each having an input (e.g., 77) controlling a plurality of computers (e.g., 205), generate and output user information at receiver stations. Under broadcast control, local computers (73, 205), combine user information selectively into prior art communications to exhibit personalized mass media programming at video monitors (202), speakers (263), printers (221), etc. At intermediate transmission stations (e.g., cable television stations), signals in network broadcasts and from local inputs (74, 77, 97, 98) cause control processors (71) and computers (73) to selectively automate connection and operation of receivers (53), recorder/players (76), computers (73), generators (82), strippers (81), etc. At receiver stations, signals in received transmissions and from local inputs (225, 218, 22) cause control processors (200) and computers (205) to automate connection and operation of converters (201), tuners (215), decryptors (224), recorder/players (217), computers (205), furnaces (206), etc. Processors (71, 200) meter and monitor availability and usage of programming.

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.

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.

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.

The receiver station receives an electronic digital information transmission including operating system instructions and a digital control signal that designates a designated hardware version of a programmable device. The received operating system instructions are communicated to the memory if a match occurs between the designated hardware version included in the transmission and the specific version of the programmable device resident at the receiver station..Iaddend.

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.
