Claim:
1. A digital broadcast signal processing method for providing stereoscopic three-dimensional (3D) video, the digital broadcast signal processing method comprising: encoding a video stream of two-dimensional (2D) primary video; encoding a video stream of secondary video for generating binocular-parallax 3D video together with the encoded video stream of the 2D primary video; generating first signaling information for the primary video and second signaling information for the secondary video; generating a first broadcast signal including the encoded video stream of the primary video and the first signaling information; generating a second broadcast signal including the encoded video stream of the secondary video and the second signaling information; and transmitting at least one of the first broadcast signal via a first channel of a broadcast network and the second broadcast signal via a second channel of the broadcast network, wherein the first signaling information includes enhancement type information indicating whether the secondary video is transmitted via the second channel of the broadcast network or a broadband network, wherein the first signaling information further includes sync type information indicating whether the secondary video is transmitted in real time or in non-real time, wherein the second signaling information which is transmitted in the second broadcast signal via the second channel of the broadcast network includes first information indicating whether or not the secondary video is inactivated in a receiver.
