    摘要: Provided is a method for constructing a key graph for multi-group multi-casting service and managing a key. The method includes: searching for a user group set (common group set) having the same access right to each resource combination comprising multiple resource selected from resources for a service and non-overlapping with other resource combinations by using an access right relations between user groups and the resource; and constructing a key graph by interconnecting a user group key and a resource key using the access right relation, where user groups pertaining to the searched common group set are connected to corresponding resources via intermediate nodes.

    摘要: A broadcasting service monitoring apparatus includes: a stream separation unit to extract a partial stream from an inputted 3D stream and separate detailed stream configuration and service-related information and a stream for 3D video service from the 3D stream; a configuration information analysis unit to minutely analyze the separated service-related information and the separated stream for 3D video service; a 2D image decoding unit to decode the separated stream for 3D video service into a predetermined image; an image separation unit to separate one screen of the decoded predetermined image into two screens and generate two images; a 3D image reproduction unit to reproduce the generated two images; a depth information extraction unit to extract depth information for 3D video service from the generated two images; and a 3D information representation unit to represent the analyzed values and the extracted depth information.
