Abstract:
PURPOSE: A method and a device for managing multicast resources efficiently provide limited resources for a plurality of users. CONSTITUTION: A resource manager (710) allocates a multicast resource to a multicast group, and generates a MAP information element (MAP IE). The MAP IE includes information of the multicast resource and a transmission indication for indicating whether the multicast resource is fragmented. A transmitter (720) transmits the MAP IE to the multicast group. The MAP IE further includes an allocation period indicating a period in which the multicast resource is allocated, and an expiry date in which allocation of the multicast resource is maintained.

Abstract:
PURPOSE: A synchronous channel transmitting method, a device thereof, a synchronous channel receiving method, and a device thereof are provided to minimize the inefficiency of resources and the degradation of a synchronous channel preamble receiving performance due to the insertion of a fixed transceiving transition time. CONSTITUTION: A synchronous channel transmitting device (700) includes a transmitter (710), a receiver (720), and a controller (730). The transmitter transmits a synchronous channel preamble part after transmitting a synchronous channel message part. The receiver receives a dedicated channel from different terminals after the transmitter transmits a synchronous channel. The controller inserts a transition time gap in the end of the synchronous channel preamble part for a transceiving transition time of a terminal of the synchronous channel transmitting device.

Abstract:
PURPOSE: A method for encoding/decoding a depth image and an apparatus thereof are provided to enable a decoder to correct errors generated during a depth image coding/decoding process using characteristic information of a depth image. CONSTITUTION: A depth image decoder receives characteristic information of a depth image (S910). The depth image decoder decodes the received characteristic information of the depth image (S920). When the decoding of the received characteristic information is completed, the depth image decoder decodes the depth image using the decoded characteristic information (S930).

Abstract:
PURPOSE: A transceiving device for 2D mode play in a digital terminal, a 2D mode play device in the digital terminal, and a method thereof are provided to selective supply a higher quality image from among two eye images by using additional 3D-related information when playing a received 3D program in a 2D form. CONSTITUTION: A generating unit(910) generates additional 3D-related information. The additional 3D-related information includes identification information indicating a proper image for a 2D mode from among additional images and reference images composing a 3D program. An identification information generating unit(915) of the generating unit generates the identification information based on a format type of stereoscopic content. A providing unit(930) provides the additional 3D-related information to a 3D terminal.

Abstract:
PURPOSE: A three dimensional image panel, a three dimensional display apparatus and a driving method are provided to minimize a crosstalk by minimizing a discontinuity phenomenon generated when moving a barrier by using a parallax barrier and offer a soft and free three dimensional image. CONSTITUTION: A three dimensional image panel(500) comprises the followings: a liquid crystal layer(510) blocking or transmitting the image played from an image panel(400); a first parallax barrier layer(1PB) including a first electrode portion(520) which is adjacent to one side of the liquid crystal layer and a second electrode portion(530) which is facing the other side of the liquid crystal layer; and a second parallax barrier layer(2PB) including a fourth electrode portion(550) which is located adjacent to a third electrode portion(540) facing one side of the liquid crystal layer between the liquid crystal layer and the first electrode portion(520) and the second electrode portion(530). The second electrode portion(530) is located between the liquid crystal layer(510) and the fourth electrode portion(550).
Abstract:
PURPOSE: A communication method of a base station and a terminal is provided to configure an optimal temporary topology for a multi-mode terminal. CONSTITUTION: Each terminal(210,220,230) transmits state information to each base station(100)(S240,S250,S260). When one of the terminals is selected from the base station, the selected terminal receives a mode conversion request from the base station(S280). The terminal is operated as the base station. The terminal is operated as a relay station.

Abstract:
PURPOSE: A communication method of a base station, a relay station, and a terminal is provided to continuously offer a communication service through a relay station or a neighbor base station when a backhaul link of a base station is damaged. CONSTITUTION: A base station(110) includes a predetermined mark in a DCD(Downlink Channel Descriptor) or an SCD(System Configuration Descriptor) message. The predetermined mark is related to the operation of the base station or the operation of a relay station. The base station transmits the SCD message or the DCD message to a terminal(200).
