20150098508 | METHOD AND DEVICE FOR ENCODING THREE-DIMENSIONAL IMAGE, AND DECODING METHOD AND DEVICE - Disclosed is a method for encoding an image through motion vector prediction which can be applied to a three-dimensional image, an encoding device, a decoding method, and a decoding device. The encoding method is an encoding method for a current prediction unit in a three-dimensional image, and comprises the steps of: selecting a motion vector of a peripheral block having the same depth as a current prediction unit as a candidate prediction motion vector of the current prediction unit, among motion vectors of already-encoded peripheral blocks of the current prediction unit; and performing inter prediction based on the candidate prediction motion vector, predicting a motion vector of the current prediction unit, and transmitting the motion vector to a decoder. Thus, a candidate for a prediction motion vector can be efficiently selected with respect to a three-dimensional image having depth information. | 04-09-2015 |
20150249835 | METHOD FOR ADAPTIVELY TRANSMITTING FEC PARITY DATA USING CROSS-LAYER OPTIMIZATION - Provided is a method for transmitting multi-media in a heterogeneous network transmission environment or a hybrid transmission environment of broadcasting and broadband IP networks, in which information for PHY channel state information is transmitted so that same is comprised in the header of a forward error correction (FEC) parity unit, and on the basis of the channel state information, when the channel state is good, the amount of parity data is reduced so as to raise the data transmission rate, and when the channel state is poor, the amount of parity data is increased so that data errors are corrected at a high rate, thus reducing the number of data re-transmissions, and thereby raising the data transmission rate. | 09-03-2015 |
20150256809 | METHOD FOR INDUCING DISPARITY VECTOR IN PREDICTING INTER-VIEW MOTION VECTOR IN 3D PICTURE - In a method for inducing a disparity vector in predicting an inter-view motion vector a 3D picture, the disparity vector is induced by adaptively searching a different number of depth samples within a block according to the size of a current block, for example, the size of a prediction unit, and then obtaining a maximum depth value. As a result, coding/decoding gain can be increased compared to a method for searching depth samples with respect to a fixed block size. | 09-10-2015 |
20150256845 | METHOD FOR PREDICTING INTER-VIEW MOTION AND METHOD FOR DETERMINING INTERVIEW MERGE CANDIDATES IN 3D VIDEO - In a method for predicting motion in a 3D multi-view video, when inter-view motion in predicting in the 3D multi-view video, a prediction motion vector with respect to a current view picture is calculated by using a motion parameter of one inter-view picture from a plurality of inter-view pictures that have been previously encoded, in order to calculate the prediction motion vector of the current view picture. As a result, complexity can be reduced by simplifying inter-view motion prediction. | 09-10-2015 |
