    Abstract: Disclosed is a broadcasting signal transmission device, a broadcasting signal reception device, and a method for transmitting/receiving a broadcasting signal using same. The method for receiving the broadcasting signal comprises the following steps: receiving the broadcasting signal, which includes a transmission frame, wherein the transmission frame includes a plurality of PLPs, which transmit components that constitute a broadcasting service, first signaling information and second signaling information, which include the signaling information of the plurality of PLPs, a first preamble signal, which has been signaled with a preamble format, and a second preamble signal, which has been signaled with pilot pattern information, wherein one of the plurality of PLPs is a base PLP, which includes a program number that corresponds to the broadcasting service and program map table information, which has been signaled with identifying information for each of the PLPs; demodulating the broadcasting signal based on the first and the second preamble signals; FEC decoding the demodulated broadcasting signal; and identifying a PLP group that includes the plurality of PLP from the FEC decoded broadcasting signal based on the first and the second signaling information, decoding at least one PLP of the identified PLP group, and providing the broadcasting service.

    Abstract: A digital broadcast receiving apparatus for providing an integrated service of a 2D image and a 3D image comprises: a demultiplexing unit configured to demultiplex a received digital broadcast signal; a PSIP or PSI/SI processor configured to extract at least any one of 3D service information related to a 2D image channel or service and 2D service information related to a 3D image channel or service from the demultiplexed digital broadcast signal; a decoder configured to decode an extension view video stream and a base view video stream from the demultiplexed digital broadcast signal; and an output formatting unit configured to format the extension view video stream and the base view video stream based on at least any one of the 3D service information and the 2D service information. When a selection of the 3D image service is input by a user, a 3D image channel or service providing a 3D image with respect to the 2D image channel or service based on the 3D service information may be selected, and when a selection of the 2D image service is input by the user, a 2D image channel or service providing a 2D image with respect to the 3D image channel or service based on the 2D service information may be selected. Accordingly, an integrated service of a 2D image and a 3D image can be provided in a digital broadcast.

    Abstract translation: 一种用于提供2D图像和3D图像的综合服务的数字广播接收装置包括：解复用单元，被配置为对所接收的数字广播信号进行解复用; 被配置为从解复用的数字广播信号中提取与2D图像信道或服务相关的3D服务信息和与3D图像信道或服务相关的2D服务信息中的至少任何一个的PSIP或PSI / SI处理器; 解码器，被配置为从解复用的数字广播信号解码扩展视图视频流和基本视点视频流; 以及输出格式化单元，被配置为基于3D服务信息和2D服务信息中的至少任一个格式化扩展视图视频流和基本视点视频流。 当用户输入3D图像服务的选择时，可以选择基于3D服务信息相对于2D图像信道或服务提供3D图像的3D图像信道或服务，并且当选择2D图像 图像服务由用户输入，可以选择基于2D服务信息相对于3D图像信道或服务提供2D图像的2D图像信道或服务。 因此，可以在数字广播中提供2D图像和3D图像的综合服务。

    Abstract: Disclosed are a broadcast signal transmitting apparatus, a broadcast signal receiving apparatus, and a broadcast signal transceiving method in the broadcast signal transmitting and receiving apparatuses. The broadcast signal transmitting method comprises the steps of: compressing headers of data packets which are included in an Internet protocol (IP) stream identified by access information, wherein the compressed data packets include a first packet containing both static information and dynamic information in the header thereof, and a second packet containing dynamic information in the header thereof; splitting the static information from the header of the first packet and diverting the remaining part thereof into the second packet; outputting an IP stream, which includes the second packet, via a data physical layer pipe (PLP); outputting, via a common PLP, a common stream, which includes the static information of the header of the first packet split in the previous step, compression information and IP-PLP mapping information for linking the IP stream and the data PLP; generating a signal frame on the basis of the data from the data PLP and the data of the common PLP; and transmitting a broadcast signal which includes the signal frame.
