Abstract

The present invention relates to a providing a method and/or an apparatus for transceiving a broadcast signal for a panorama broadcast service. The method for transmitting a broadcast signal, according to one embodiment of the present invention, comprises the steps of: encoding an image, multiplexing into a single broadcast stream, the encoded image and signaling information related to the image, wherein the signaling information includes signaling information related to a panoramic image; generating a broadcast signal including the multiplex broadcast stream; and transmitting the generated broadcast signal.

First claim

1 . A method of transmitting a broadcast signal, comprising:
encoding an image; multiplexing the encoded image and signaling information about the image into a single broadcast stream, wherein the signaling information includes signaling information about a panoramic image; generating a broadcast signal including the multiplexed broadcast stream; and transmitting the generated broadcast signal.

2 . The method according to claim 1 , wherein the signaling information about the image includes event connection information indicating information about a panorama broadcast service corresponding to a currently viewed broadcast service, and the signaling information about the panoramic image includes panorama composition information indicating a composition of the panoramic image.

3 . The method according to claim 2 , wherein the encoding comprises dividing the image into one or more images and respectively encoding the divided images.

4 . The method according to claim 2 , wherein the encoding comprises encoding additional information on a region of interest (ROI) of a user in the image, for providing a high-definition image of the ROI, and the multiplexing comprises multiplexing the encoded image, the signaling information about the image and the encoded ROI additional information into a single broadcast stream.

5 . The method according to claim 3 , wherein the panorama composition information includes information about the divided images.

6 . The method according to claim 3 , wherein the panorama composition information includes filtering information for removing blocking artifacts from the divided images.

7 . The method according to claim 2 , wherein the panorama composition information includes information for cropping the panoramic image into one or more images.

8 . The method according to claim 4 , wherein the panorama composition information includes information about the image of the ROI.

9 . A method of receiving a broadcast signal, comprising:
receiving a broadcast stream including a stream with respect to an image and signaling information about the image, wherein the signaling information includes signaling information about a panoramic image; extracting the stream with respect to the image and the signaling information about the image from the received broadcast stream; and decoding the extracted stream with respect to the image using the extracted signaling information.

10 . The method according to claim 9 , wherein the signaling information about the image includes event connection information indicating information about a panorama broadcast service corresponding to a currently viewed broadcast service, and the signaling information about the panoramic image includes panorama composition information indicating a composition of the panoramic image.

11 . The method according to claim 10 , wherein the image is divided into one or more images and the stream with respect to the image includes streams with respect to the one or more divided images,
wherein the decoding comprises respectively decoding the streams with respect to the divided images using the extracted signaling information.

12 . The method according to claim 10 , wherein the broadcast stream includes a stream with respect to additional information on an ROI of a user in the image, for providing a high-definition image of the ROI,
wherein the extracting comprises extracting the stream with respect to the image, the stream with respect to the ROI additional information and the signaling information about the image from the received broadcast stream, and the decoding comprises decoding the extracted stream with respect to the image and the extracted stream with respect to the ROI additional information using the extracted signaling information.

13 . The method according to claim 11 , wherein the panorama composition information includes information about the divided images.

14 . The method according to claim 11 , wherein the panorama composition information includes filtering information for removing blocking artifacts from the divided images.

15 . The method according to claim 10 , wherein the panorama composition information includes information for cropping the panoramic image into one or more images.

16 . The method according to claim 12 , wherein the panorama composition information includes information about the image of the ROI.

17 . The method according to claim 9 , further comprising displaying the decoded stream with respect to the image,
wherein the displaying comprises displaying a region shifted according to a scrolling request when the scrolling request is received from a user.

18 . An apparatus for transmitting a broadcast signal, comprising:
an encoder for encoding an image; a multiplexer for multiplexing the encoded image and signaling information about the image into a single broadcast stream, wherein the signaling information includes signaling information about a panoramic image; a broadcast signal generator for generating a broadcast signal including the multiplexed broadcast stream; and a transmitter for transmitting the generated broadcast signal.

19 . An apparatus for receiving a broadcast signal, comprising:
a receiver for receiving a broadcast stream including a stream with respect to an image and signaling information about the image, wherein the signaling information includes signaling information about a panoramic image; a demultiplexer for extracting the stream with respect to the image and the signaling information about the image from the received broadcast stream; and a decoder for decoding the extracted stream with respect to the image using the extracted signaling information.
