Abstract:
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.
