    Abstract: Disclosed are a video reproduction apparatus for three-dimensional television (3DTV) and a processing method for the same. The video reproduction apparatus can determine the output time of a buffer which stores right-image stream and left-image stream for a 3D image, and can determine a buffer size or a buffer delay time by using the difference between the reception times of the right-image stream and the left-image stream. Furthermore, the video reproduction apparatus can correct a reference clock or a timestamp by using the difference between the reception times of the right-image stream and the left-image stream.

    Abstract: PURPOSE: An image compression standard determination method is provided to encode a low quality image by determining an image compression standard based on the resolution of the low compression standard. CONSTITUTION: An image compression standard determination apparatus encodes a high quality image(210). The image compression standard determination apparatus determines an image compression standard(220). The low quality image is encoded by the determined image compression standard in case the average power of quantization noise in the encoded low quality image is under than the average power of the quantization noise in the encoded high quality image(230,240). The image compression standard determination apparatus transmits streams for the encoded low quality image to a second channel(260).
