TECHNICAL FIELD

The present invention relates to an apparatus for transmitting a broadcast signal, an apparatus for receiving a broadcast signal and methods for transmitting and receiving a broadcast signal.

BACKGROUND ART

As analog broadcast signal transmission comes to an end, various technologies for transmitting/receiving digital broadcast signals are being developed. A digital broadcast signal may include a larger amount of video/audio data than an analog broadcast signal and further include various types of additional data in addition to the video/audio data.

DISCLOSURE

Technical Problem

That is, a digital broadcast system can provide HD (high definition) images, multichannel audio and various additional services. However, data transmission efficiency for transmission of large amounts of data, robustness of transmission/reception networks and network flexibility in consideration of mobile reception equipment need to be improved for digital broadcast.

Technical Solution

The object of the present invention can be achieved by providing a broadcast signal reception method including receiving, through a broadcast network, a broadcast signal including a first component of DASH content capable of being received through the broadcast network and a broadband network, decapsulating the received broadcast signal to output LCT packets transmitted through at least one LCT channel, acquiring signaling information included in the output LCT packets, acquiring segments corresponding to the first component of the DASH content included in the LCT packets using the acquired signaling information, and decoding the acquired segments.

Advantageous Effects

The present invention can control quality of service (QoS) with respect to services or service components by processing data on the basis of service characteristics, thereby providing various broadcast services.

The present invention can achieve transmission flexibility by transmitting various broadcast services through the same radio frequency (RF) signal bandwidth.

The present invention can provide methods and apparatuses for transmitting and receiving broadcast signals, which enable digital broadcast signals to be received without error even when a mobile reception device is used or even in an indoor environment.

The present invention can effectively support future broadcast services in an environment supporting future hybrid broadcasting using terrestrial broadcast networks and the Internet.
