Abstract

A broadcast signal reception method and a reception system are provided. The reception system includes a first processor, a second processor, and a storage medium. The first processor receives and processes a signaling table, the signaling table comprising first signaling information including access information of Non-Real-Time (NRT) service data and second signaling information including media object association information of the NRT service data. The second processor receives the NRT service data and processes a file including the received NRT service data based on the access information and the media object association information processed by the first processor. The storage medium stores the processed file of the NRT service data.

Claims

1. A method of transmitting a broadcast signal for a broadcast service, the method comprising:

generating the broadcast service including non-real-time (NRT) content;

generating signaling data for signaling the broadcast service; and

transmitting the broadcast service and the signaling data,

wherein the signaling data is transmitted via a signaling path through internet Protocol (IP) packets,

wherein the signaling data includes an information table including information for service acquisition for broadcast services,

wherein the information table further includes service category information specifying a category of the broadcast service,

wherein the information table further includes protection information indicating whether one or more components needed for presentation of the broadcast service are protected,

wherein the information table further includes service identification information identifying the broadcast service,

wherein the information table further includes short service name information indicating a short name of the broadcast service, and

wherein the signaling data further includes a transport session description fragment including a Transport Session Identifier (TSI) for identifying a transport channel and bandwidth information specifying a maximum bit-rate required by the identified transport channel.

2. A method for receiving a broadcast signal for a broadcast service, the method comprising:

receiving the broadcast service including non-real-time (NRT) content;

receiving signaling data for signaling the broadcast service, the signaling data received via a signaling path through Internet Protocol (IP) packets;

parsing an information table from the received signaling data, the parsed information table including information for service acquisition for broadcast services,

obtaining service category information specifying a category of the broadcast service from the parsed information table;

obtaining protection information from the parsed information table, the protection information indicating whether one or more components needed for presentation of the broadcast service are protected;

obtaining service identification information from the parsed information table, the service identification information identifying the broadcast service;

obtaining short service name information from the parsed information table, the service name information indicating a short name of the broadcast service; and

storing the broadcast service,

wherein the signaling data includes a transport session description fragment including a Transport Session Identifier (TSI) for identifying a transport channel and bandwidth information specifying a maximum bit-rate required by the identified transport channel.

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

a tuner that receives the broadcast service including non-real-time (NRT) content;

a storage unit that stores the broadcast service,

wherein signaling data is received via a signaling path through Internet Protocol (IP) packets; and

a processor that;

parses an information table from the received signaling data, the parsed information table including information for service acquisition for broadcast services,

obtains service category information specifying a category of the broadcast service from the parsed information table;

obtains protection information from the parsed information table, the protection information indicating whether one or more components needed for presentation of the broadcast service are protected;

obtains service identification information from the parsed information table, the service identification information identifying the broadcast service;

obtains short service name information from the parsed information table, the service name information indicating a short name of the broadcast service; and

stores the broadcast service in the storage unit,

wherein the signaling data includes a transport session description fragment including a Transport Session Identifier (TSI) for identifying a transport channel and bandwidth information specifying a maximum bit-rate required by the identified transport channel.
