Abstract: A 3-dimensional (3D) service processing device and method of processing a 3D service are described. The 3D service processing device is configured to receive a first signal including a first video stream via a first channel, and a second signal including a second video stream via a second channel. The first signal includes linkage information. The 3D service processing device searches for a stream position for pairing the first video stream and the second video stream based on the linkage information. The 3D service processing device generates the 3D service based on the paired first and second video streams, and at least one of first synchronization information for synchronizing the first video stream or second synchronization information for synchronizing the second video stream.
