Abstract:
An operating method of an overlay management server (OMS) is disclosed. The operating method may include performing a registration process along with a network entity, performing a resource reservation process along with the network entity in response to the registration process being performed, receiving a peer list provision request from the network entity in response to the resource reservation process being performed, and transmitting, to the network entity, a peer list including information associated with an overlay resource for the network entity based on a priority level of the network entity in response to the peer list provision request being received.
Abstract:
Provided is an operation method of a receiving entity, the method including setting a session with a sending entity based on bootstrap information; transmitting a signaling message corresponding to a media delivery request to the sending entity through the session; receiving media data from the sending entity through the session; and transmitting a signaling message corresponding to a media delivery control request to the sending entity through the session while receiving the media data.
Abstract:
To conduct video conferencing between a plurality of distributed clients, a distributed controller receives a request from a first distributed client for a packet from a second distributed client selected as the main speaker, and a distributed media processor creates a switching entry for switching packets from the first and second distributed clients, in response to a request from the distributed controller. The distributed controller sends a packet transmission request to the second distributed client, and the distributed media processor receives a packet from the second distributed client and sends the received packet to the first distributed client based on the switching entry.
Abstract:
Disclosed herein are a method and apparatus for time-assisted authentication. A main authentication entity may generate a group of communication entities. In keying protocol a key distributor, i-e main authentication entity, controls the key generation arguments and time factor; other member of the group independently generate the time-based keys using the key generation arguments. Respective keys in the chain of keys may be valid for time intervals predefined for respective keys. A ticket is issued to the valid customer node during initial authentication process, which is further used for re-authentication of customer node with other service providing entities and customer to customer node mutual authentication. A ticket verifier may authenticate a customer node by decrypting the ticket using time based keys.
Abstract:
A terminal is provided. The terminal includes a first sensor disposed in a screen region and configured to sense a user's first touch, a second sensor disposed in a region other than the screen region and configured to sense at least two user's second touches, and a controller configured to perform a multi-touch operation when the first touch is sensed through the first sensor and at least one of the second touch is sensed through the second sensor.
Abstract:
A frost prediction system includes: a weather observation data collection sensor attached to a meteorological station and configured to collect weather observation data and to transmit real-time weather observation data to a server; a training data generation unit configured to generate frost prediction training data by using the collected weather observation data; and a frost prediction unit configured to perform frost prediction for the next day by applying the generated frost prediction training data to a frost learning model.
Abstract:
A system and a method for cultivating roughage are disclosed. The system includes a cultivator console for providing user interface to a grower, a cultivation server for calculating a cultivation environment adjustment value for the roughage based on information received from the cultivator console, and a cultivation apparatus for controlling the environment of a cultivation space for cultivating the roughage based on the cultivation environment adjustment value.
Abstract:
Disclosed is a network entity configured to receive a package access (PA) message associated with signaling for consuming a media package from a sending entity, verify, in response to a request for changing media data in the media package, whether the media data is changeable based on a flag in the PA message, change the media data and update the PA message when the media data is changeable, and transmit the changed media data and the updated PA message to a receiving entity.
Abstract:
A terminal including an eye-tracking unit for tracking a gaze of a user to generate gaze information, a touch sensing unit for sensing a touch of the user to generate touch information, and a controller for performing a touch operation based on the gaze information and the touch information are provided.
