Abstract
Provided is a method for transmitting a broadcast signal, the method including generating a plurality of input packets including broadcast data, generating at least one link layer packet using the input packets, wherein a header of the link layer packet includes packet type information and first length information, the packet type information indicates a type of an input packet included in a payload of the link layer packet, and the first length information indicates a length of the payload, generating a broadcast signal using the link layer packet, and transmitting the broadcast signal.
Claims14
A method for transmitting a broadcast signal, the method comprising:
- generating a plurality of input packets comprising service data for a broadcast service;
- generating a link layer packet using the input packets, the link layer packet including a header and payload including the service data of the input packets,
- wherein the header of the link layer packet comprises packet type information and first length information, the packet type information indicates a type of the service data included in the payload, and the first length information indicates a length of the payload;
- generating a broadcast signal using the link layer packet;
- and
- transmitting the broadcast signal,
- wherein when the payload includes a plurality of concatenated input packets, the header further includes component length fields indicating lengths of the input packets, and the component length fields are positioned in the same order as the input packets present in the payload, and
- wherein the header further includes a header extension having an extension type field, an extension length field and extended header information for the service data, the extension type field indicates a type of the header extension and the extension length field provides information about a length of the extended header information.
An apparatus for transmitting a broadcast signal, the apparatus comprising;
- a first processor for generating a plurality of input packets comprising service data for a broadcast service:
- a second processor for generating a link layer packet using the input packets, the link layer packet including a header and a payload including the service data of the input packets, wherein the header of the link layer packet comprises packet type information and first length information, the packet type information indicates a type of the service data included in the payload, and the first length information indicates a length of the payload;
- a third processor for generating, a broadcast signal using the link layer packet;
- and
- a fourth processor for transmitting the broadcast signal,
- wherein when the payload includes a plurality of concatenated input packets, the header further includes component length fields indicating lengths of the input packets, and the component length fields are positioned in the same order as the input packets present in the payload, and
- wherein the header further includes a header extension having an extension type field, an extension length field and extended header information for the service data, the extension type field indicates a type of the header extension and the extension length field provides information about a length of the extended header information.
