    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).

    Abstract: PURPOSE: A synchronization method for implementing a 3D service in ATSC-M/H is provided to adjust synchronism between a TS(transmission stream)-M stream and an M/H stream. CONSTITUTION: A TS inputted to a dual stream through a receiver is separated into a TS-M stream and a M/H stream through an inverse multiplexer. Each of timing models is analyzed to adjust synchronism between streams including two different timing models and to find reference information shared between the timing models. Synchronization between heterogeneous streams is performed based on PTS(Presentation Time Stamp) information generated through a wall-clock. A 3D image is formed through the synchronization by using the heterogeneous streams having the same time synchronism.
