20140320597 | 3D BROADCAST SERVICE PROVIDING METHOD AND APPARATUS, AND 3D BROADCAST SERVICE REPRODUCTION METHOD AND APPARATUS FOR USING IMAGE OF ASYMMETRIC ASPECT RATIO - Disclosed are a method and apparatus for providing a three-dimensional (3D) broadcast service using images with asymmetric aspect ratios and a method and apparatus for reproducing a 3D broadcast service. The method of providing the 3D broadcast service includes adjusting a second viewpoint image to be composed with a first viewpoint image into a 3D form with respect to the first viewpoint image and the second viewpoint image for 3D broadcasting, encoding the first viewpoint image and the adjusted second viewpoint image, and generating a broadcast stream of the first viewpoint image and a broadcast stream of the second viewpoint image by multiplexing the first viewpoint image and the second viewpoint image. | 10-30-2014 |
20140340480 | APPARATUS AND METHOD FOR MANAGING DELAY IN RECEIVING THREE-DIMENSIONAL (3D) IMAGE - An apparatus for managing a delay in receiving a three-dimensional (3D) image may include an image receiver to receive a left image and a right image for 3D image synthesis, and a substitution content output unit to output substitution content during a waiting time caused by a difference between points in time at which the left image and the right image are received. | 11-20-2014 |
20150062298 | IMAGE QUALITY INCREASING APPARATUS AND METHOD - An image quality increasing apparatus for a binocular three-dimensional television (3DTV) is disclosed. The image quality increasing apparatus may include an error detection unit to detect whether a reference image includes an error, a reference information correction unit to correct reference information for increasing an image quality of an additional image based on a detection result, an image quality increasing unit to increase the image quality of the additional image corresponding to the reference information, and a three-dimensional (3D) image synthesis unit to synthesize a 3D image using the quality increased additional image and the reference image. | 03-05-2015 |
20150109411 | IMAGE PLAYBACK APPARATUS FOR 3DTV AND METHOD PERFORMED BY THE APPARATUS - An image reproduction apparatus for a 3DTV and a processing method by the apparatus are disclosed. The image reproduction apparatus may determine an output time of a buffer to store a left image stream and a right image stream for a 3D image. The image reproduction apparatus may determine a buffer size or a buffer delay time using a reception time difference between the left image stream and the right image stream. Further, the image reproduction apparatus may correct a reference clock or a timestamp using the reception time difference between the left image stream and the right image stream. | 04-23-2015 |
