Abstract:
The present invention relates to a method of synchronizing a reference image with an additional image of a real-time broadcasting program, the method comprising the steps of: generating at least one frame having a predetermined identifier for providing notice of the start time of the reference image to a receiver in advance; and transmitting at least one frame having the predetermined identifier to the receiver. Alternatively, the method of synchronizing a reference image with an additional image of a real-time broadcasting program comprises the steps of: generating signaling information containing additional image interlocking information at a transmission side in order to prepare for the additional image interlocked with the reference image of the real-time broadcasting program at a reception side in advance; and providing the signaling information to the receiver. Therefore, it is possible to accurately and effectively perform the synchronization of a 3D reference image of the real-time broadcasting program with a 3D additional image stored in the receiver or a streamed 3D additional image.

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.

Provided are a multi-display supporting multi-view video object-based encoding apparatus and method, and an object-based transmission/reception system and method using the encoding apparatus and method. The encoding apparatus includes: a shape abstracting means for receiving right/left-eye image object video and abstracting right/ left object image, respectively, to abstract the shape information of a multi-view video; a data separating means for receiving the right/left-eye image object video, and the right/left shape information, and separating them into odd-field objects and even field objects to transmit only the essential bit streams for a user display mode; a shape compensation means for compensating for the distortion of the shape information separated into odd and even fields; and an object-based encoding means for receiving the object-based information from the shape compensation means and the object-based information from the data separating means, forming four layers, and performing motion and disparity estimation to encode object-based data that are separated into odd and even lines.

Provided is a stereoscopic video encoding and/or decoding apparatus that supports multi-display modes, the encoding/decoding method thereof and computer-readable recording medium for recording a program that implements the encoding/decoding method. The encoding apparatus of this research incorporates: a field separating means for separating right and left-eye input images into an odd field of the left-eye image (LO), even field of the left-eye image (LE), odd-numbered field (RO) of the right-eye image, and even-numbered field (RE) of the right-eye image; an encoding means for encoding the fields separated in the field separating means by performing motion and disparity compensation; and a multiplexing means for multiplexing the essential fields among the fields received from the encoding means, based on the user display information.
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:
Method and device for synchronizing reference image and supplementary image in real-time broadcast program. The present invention provides a synchronization method for: calculating a time difference between a current frame of a reference image and a reference time stamp on the basis of the reference time stamp, which is contained in a program level descriptor and indicates a start time of a frame regarding a reference image; and adjusting synchronization between the frame regarding the reference image and a frame regarding a supplementary image by using the time difference. Since synchronous time information is signaled together with a stream delivered in real time, synchronization between a stored supplementary image and a reference image transmitted in real time is enabled even though a first PMT of a time when a stereoscopic video service is started is not received or a packet error is generated. Thus, the invention can provide a stable stereoscopic image service
