1. A method for transmitting a broadcast signal by an apparatus for transmitting a broadcast signal, comprising:
- encoding an original panoramic image, wherein the original panoramic image is divided into two or more images and wherein each divided image is encoded and carried by a video stream, respectively;
multiplexing the divided images and signaling information about the original panoramic image and the divided images into a single broadcast stream;
generating a broadcast signal including the multiplexed broadcast stream; and
transmitting the generated broadcast signal,wherein the signaling information includes resolution information of the original panoramic image, information indicating a number of video stream carrying the divided images and composition information of the original panoramic image,wherein the composition information of the original panoramic image includes resolution information of each divided image carried by the video stream, andwherein the signaling information further includes an active format description which includes start coordinate values of an active portion belonging to the divided images and the active portion is a partial image of the divided image to be displayed.
