A system, method and program product for a distributed video presentation with presenter system control of video on viewer systems. The presenter system and the plurality of distributed viewer systems have a presentation application for viewing a video in a presentation mode. At least one video data channel is established for serving the video to the plurality of distributed viewer systems during the presentation mode. At least one video control signal channel is established for controlling display of the video on the plurality of distributed viewer systems. Each of the video data channels is separate from all of the video control signal channels and the presenter system has sole control over the at least one video control signal channel to control display of the video on the plurality of distributed viewer systems.

Provided is novel technology for secure security data transmission and more particularly for registering network-enabled security devices such as IP cameras to a security server over a public network such as to a cloud-based security service. An enrolment server is provided that is logged into using a computing device to request and receive an activation code for the security device. The activation code is then provided to the security device, e.g. directly by the computing device. The Security device authenticates itself based on the activation code and in one example provides a public key that will be used to verify its registration. Data transmissions by the device are secured in part on the basis of its registration.

Different data communication architectures deliver a wide variety of content, including audio and video content, to consumers. The architectures employ channel bonding to deliver more bandwidth than any single communication channel can carry. In some implementations, the communication architectures distribute data streams to bonded channels that are clocked independently. A system is provided for synchronizing the bonded channels.

Control of access by a requesting entity to an asset includes defining an approved state of the requesting entity. A validation of a representation of the approved state of in a non-repudiatable form in obtained from an event validation system. The requesting entity is triggered to determine its current state by an access-control entity, which compares the current state with the approved state and allows access by the requesting entity to the asset only if the current state is the same as the approved state. In a pre-authorization procedure, one or both of the entities issues a data set challenge to the other, which then validates the challenge via the event validation system and returns this validation to the challenging entity, which then checks the validation to see if it is correct. Data sets may be validated, for example, with hash tree based signatures or blockchain entries.

An apparatus and a method for providing an adaptive multimedia service in a mobile communication system are provided. The method of providing a multimedia service includes collecting user-preference-aware information, device-capability-aware information, and network-aware information, generating a packet according to a correlation among the user-preference-aware information, the device-capability-aware information, and the network-aware information, and providing a multimedia service according to the generated packet.

A transmitting apparatus, a receiving apparatus and methods of controlling these apparatuses are provided. The transmitting apparatus includes: a baseband packet generator configured to, based on an input stream including a first type stream and a second type stream, generate a baseband packet including a header and payload data corresponding to the first type stream; a frame generator configured to generate a frame including the baseband packet; a signal processor configured to perform signal-processing on the generated frame; and a transmitter configured to transmit the signal-processed frame, wherein the header includes a type of the payload data in the baseband packet and the number of the first type stream packets in the baseband packet.
