Abstract

A broadcast transmitter/receiver and a 3D video data processing method of the same are disclosed. A 3D video data processing method of a broadcast transmitter includes encoding 3D video data, using an encoder, generating system information included in 3D video metadata, using a system information processor, outputting a transport stream by inserting frame sync information in the 3D vide data and multiplexing the 3D video data and system information, using a TP encoder, and modulating and transmitting the transport stream, using a transmitting unit. A 3D video data processing method of a broadcast receiver includes receiving a broadcasting signal including 3D video data having frame sync information and system information, using a reception unit, demultiplexing the 3D video data and the system information, using a demultiplexer, acquiring 3D video metadata by parsing the system information, using a system information processor, acquiring the frame sync information from the 3D video data and outputting the video data frame-sequentially based on the acquired frame sync information, using a sync controller, and decoding the 3D video data based on the 3D metadata, using a decoder.

First claim

The invention claimed is:

1. A 3D video data processing method of a broadcast transmitter comprising:
encoding, by an encoder, 3D video data including a base view component of a base layer and an extended view component of an enhancement layer;
generating, by a system information processor, signaling information including 3D video metadata; and
transmitting, by a transmitting unit, a broadcast signal including the encoded 3D video data and the signaling information,
wherein the broadcast signal further includes frame sync information specifying at least one order value of view components.

2. The 3D video data processing method of claim 1 , wherein the frame sync information for the base view component is same as the frame sync information for the corresponding extended view component.

3. The 3D video data processing method of claim 1 , wherein frame sync information comprises at least one of a Presentation Time Stamp, PTS, a Picture Order Count, POC, and a display order of the view components.

4. The 3D video data processing method of claim 1 , wherein the 3D video metadata comprises at least one of service type information identifying a 3D broadcasting service, view information indicating which of left view and right view is assigned to the base view component, stream type information specifying a type of a program element, and frame rate information representing a rate at which view components are output from a decoding process.

5. The 3D video data processing method of claim 1 , wherein the encoding of the 3D video data comprises frame-sequentially encoding the base view component and the extended view component.

6. A broadcast transmitter comprising:
an encoder for encoding 3D video data including a base view component of a base layer and an extended view component of an enhancement layer;
a system information processor for generating signaling information including 3D video metadata; and
a transmitting unit for transmitting a broadcast signal including the encoded 3D video data and the signaling information,
wherein the broadcast signal further includes frame sync information specifying at least one order value of view components.

7. The broadcast transmitter of claim 6 , wherein the frame sync information for the base view component is same as the frame sync information for the corresponding extended view component.

8. The broadcast transmitter of claim 6 , wherein frame sync information comprises at least one of a Presentation Time Stamp, PTS, a Picture Order Count, POC, and a display order of the view components.

9. The broadcast transmitter of claim 6 , wherein the 3D video metadata comprises at least one of service type information identifying a 3D broadcasting service, view information indicating which of left view and right view is assigned to the base view component, stream type information specifying a type of a program element, and frame rate information representing a rate at which view components are output from a decoding process.

10. The broadcast transmitter of claim 6 , wherein the encoding of the 3D video data comprises frame-sequentially encoding the base view component and the extended view component.
