Abstract

A method of receiving and processing a Non-Real Time (NRT) service and a broadcast receiver are disclosed herein. A method of processing an NRT service in a broadcast receiver includes receiving and processing a signaling information table including detail information of each content in the NRT service and indication information indicating whether the content is available on internet, acquiring internet access information of each file belonging to content available on the internet through File Delivery Table (FDT) of File Delivery over Unidirection Transport (FLUTE) based on the indication information, and downloading files belonging to the content by accessing the internet based on the acquired internet access information.

Claims

1. A method of receiving a broadcast service, the method comprising:

receiving, by a tuner, a broadcast signal which carries internet protocol (IP) datagrams, the IP datagrams containing the broadcast service that includes one or more non-real time contents, each of which have one or more files, and signaling data,

wherein the signaling data includes service identification information identifying the broadcast service, and service status information specifying a status of the broadcast service; and

decoding, by a decoder, the signaling data,

wherein a component of the broadcast service is carried in a transport channel,

wherein the signaling data further includes a Transport Session Identifier (TSI) identifying the transport channel, first start time information representing a start time of the transport channel, first end time information representing an end time of the transport channel, bandwidth information specifying a maximum bandwidth for the transport channel, and Forward Error Correction (FEC) object transmission information for the transport channel,

wherein a non-real time content including an entry file is transported in the transport channel, and

wherein the non-real time content is launched using the entry file.

2. An apparatus for receiving a broadcast service, the apparatus comprising:

a tuner configured to receive a broadcast signal which carries internet protocol (IP) datagrams, the IP datagrams containing the broadcast service that includes one or more non-real time contents, each of which have one or more files, and signaling data,

wherein the signaling data includes service identification information identifying the broadcast service, and service status information specifying a status of the broadcast service; and

a decoder configured to decode the signaling data,

wherein a component of the broadcast service is carried in a transport channel,

wherein the signaling data further includes a Transport Session Identifier (TSI) identifying the transport channel, first start time information representing a start time of the transport channel, first end time information representing an end time of the transport channel, bandwidth information specifying a maximum bandwidth for the transport channel, and Forward Error Correction (FEC) object transmission information for the transport channel,

wherein a non-real time content including an entry file is transported in the transport channel, and

wherein the non-real time content is launched using the entry file.

3. A method for transmitting a broadcast service, the method comprising:

generating a broadcast signal which carries internet protocol (IP) datagrams, the IP datagrams containing the broadcast service that includes one or more non-real time contents, each of which have one or more files, and signaling data,

wherein the signaling data includes service identification information identifying the broadcast service, service status information specifying a status of the broadcast service,

wherein a component of the broadcast service is carried in a transport channel,

wherein the signaling data further includes a Transport Session Identifier (TSI) identifying the transport channel, first start time information representing a start time of the transport channel, first end time information representing an end time of the transport channel, bandwidth information specifying a maximum bandwidth for the transport channel, and Forward Error Correction (FEC) object transmission information for the transport channel,

wherein a non-real time content including an entry file is transported in the transport channel, and

wherein the non-real time content is launched using the entry file; and

transmitting the broadcast signal.
