Abstract

A receiving system that can receive and process 3D images and a data processing method of the same are disclosed. The receiving system includes an image receiving unit and a display unit. The image receiving unit receives a 3-dimensions (3D) image and system information including additional information of the 3D image (i.e., additional 3D image information), generates 3D signaling information based upon the additional 3D image information included in the system information, and transmits the generated 3D signaling information along with the 3D image through a digital interface. And, the display unit receives the 3D signaling information along with the 3D image through the digital interface, formats the 3D image based upon the receiving 3D signaling information, and displays the formatted 3D image.

First claim

What is claimed is:

1. A method of processing a 3-dimensional (3D) broadcast service in a receiver, the method comprising:
receiving a broadcast signal including 3D broadcast service data and service information for signaling the 3D broadcast service data, wherein the service information includes first information indicating a transmission format of the 3D broadcast service,
wherein the transmission format of the 3D broadcast service corresponds to a side-by-side format in which a left image and a right image are sub-sampled to half resolution on a horizontal axis and arranged side by side in a video frame,
wherein the service information further includes second information indicating whether a quincunx filter is used for sub-sampling the left image and the right image;
processing the 3D broadcast service data and the service information;
Transition Minimized Differential Signaling (TMDS) coding the processed 3D broadcast service data and generating an InfoFrame packet for describing the TMDS coded 3D broadcast service data based on the service information;
transmitting the TMDS coded 3D broadcast service data and the generated InfoFrame packet to a display unit,
wherein the InfoFrame packet includes the first information and the second information.

2. An apparatus for processing a 3-dimensional, (3D) broadcast service, the apparatus comprising:
a receiving unit that receives a broadcast signal including 3D broadcast service data and service information for signaling the 3D broadcast service data, wherein the service information includes first information indicating a transmission format of the 3D broadcast service,
wherein the transmission format of the 3D broadcast service corresponds to a side-by-side format in which a left image and a right image are sub-sampled to half resolution on a horizontal axis and arranged side by side in a video frame,
wherein the service information further includes second information indicating whether a quincunx filter is used for sub-sampling the left image and the right image;
a processor that processes the 3D broadcast service data and the service information;
an encoder that Transition Minimized Differential Signaling, (TMDS) codes the processed 3D broadcast service data and generates an InfoFrame packet for describing the TMDS coded 3D broadcast service data based on the service information;
a transmission unit that transmits the TMDS coded 3D broadcast service data and the generated InfoFrame packet to a display unit,
wherein the InfoFrame packet includes the first information and the second information.
