Abstract:
Disclosed are a signaling method for a stereoscopic video service and an apparatus using the method. An image decoding method comprises: a step of determining a field value based on a broadcast service type and a display mode in decoding a program level descriptor; and a step of determining an encoded stream type, whether an elementary stream is a reference stream, whether the elementary stream is a left-eye image or a right-eye image, additional image upsampling information and information on a subsampled line. Thus, efficiency of encoding/decoding an additional image for a stereoscopic video content may increase.
Abstract:
The present invention relates to a method of generating contents information for managing contents including stereoscopic contents being two-dimensional contents and three dimensional contents, and an apparatus for managing contents, the method including the steps of, when there is a scene change of contents, adding a second field including information on each of a plurality of scenes corresponding to a plurality of types, respectively, to the contents information.
Abstract:
Disclosed is a broadcast data transmission system. Said broadcast data transmission system transmits broadcast data by using a plurality of transmission antennas and a plurality of receiving antennas. A broadcast data transmission device comprised in the broadcast data transmission system determines different modulation techniques for each transmission antenna, determines different kinds of transmission power for each data stream according to the determined modulation techniques, and determines different precoding vectors.

According to the present invention, various types of stereoscopic video services may be provided.
Abstract:
Data about at least two viewpoints constituting stereoscopic video is respectively received with a time difference. A storage unit in an image processing device receives first viewpoint video data, from among the data about the two viewpoints, and uses the first viewpoint video data to generate monoscopic video. Then, after the first viewpoint video data has been stored and second viewpoint video data corresponding to the first viewpoint video data has subsequently been received, stereoscopic video can be generated and displayed by synthesising the first viewpoint video data and the second viewpoint video data.
Abstract:
In a diverse wireless system employing QAM modulation of symbols received via different fading channels, an input vector signalxcomprising subvectorsx1-kis iteratively constellation-rotated 110 through a number of rotations n, divided into real and imaginary values 120 and cyclically shifted 130 to generate a final rotation vector signalr. When this signal is received (410), a signal construction unit (420) generates new rotation vector signals via a constellation rotation 0k and the signals are grouped into pairs (510) and input to a complex signal construction unit (520) for cross-coupling (fig. 6).
