First Claim
1. A method of transmitting broadcast signals by an apparatus for transmitting broadcast signals, the method comprising:
- receiving input packets including broadcast data;
generating a link layer packet using the input packets, wherein the link layer packet includes a link layer header and a link layer payload including data of the input packets,wherein the link layer header includes a packet type field indicating type of the data of the input packets in the link layer payload,wherein when the packet type field indicates that the input packets are IP (Internet Protocol) packets, the link layer header further includes a packet configuration field indicating whether the link layer payload includes a segment of one input packet or a plurality of concatenated input packets,wherein when the link layer payload includes the segment of the one input packet, the link layer header further includes a segmentation information part, wherein the segmentation information part includes a segment sequence number field indicating an order of the segment carried in the link layer packet,wherein when the link layer payload includes the plurality of concatenated input packets, the link layer header further includes a concatenation information part, wherein the concatenation information part includes a count field indicating a number of the input packets included in the link layer packet; and
transmitting the generated link layer packet.

Abstract
The present invention provides a method of transmitting broadcast signals. The method includes, generating input packets including broadcast content data; generating a link layer packet by using the generated input packets, wherein the link layer packet includes a link layer header and a link layer payload including the generated input packets, wherein the link layer header includes a count field indicating number of the input packets included in the link layer payload, wherein the link layer header further includes a length part, wherein the length part includes a plurality of length fields as many as that the count field indicates, wherein each of the length fields indicates length of the each input packets included in the link layer payload; generating a broadcast signal including the generated link layer packet; and transmitting the broadcast signal.
