Abstract

A transmitting apparatus is provided. The transmitting apparatus includes at least one processor configured to implement: an L1 signaling generator configured to generate L1 signaling; a frame generator configured to generate a frame having a payload in which a plurality of Physical Layer Pipes (PLPs) are included; and a signal processor configured to transmit the frame by adding a preamble including the L1 signaling in the frame. The L1 signaling includes first information representing an alignment state of starting positions of PLPs included in different layers among the plurality of PLPs and second information representing at least one offset of the starting positions. Accordingly, the preamble includes the L1 signaling including information on an arrangement order of the plurality of PLPs included in the payload.

First claim

What is claimed is:

1 . A transmitting apparatus comprising at least one processor configured to implement:
an L1 signaling generator configured to generate L1 signaling; a frame generator configured to generate a frame comprising a payload in which a plurality of Physical Layer Pipes (PLPs) are included; and a signal processor configured to transmit the frame by adding a preamble comprising the L1 signaling in the frame, wherein the L1 signaling comprises first information representing an alignment state of starting positions of PLPs included in different layers among the plurality of PLPs and second information representing at least one offset of the starting positions.

2 . The transmitting apparatus as claimed in claim 1 , wherein the L1 signaling further comprises information on an arrangement order of the PLPs included in the different layers and information on the different layers in which the PLPs are included.

3 . The transmitting apparatus as claimed in claim 2 , wherein the different layers comprise one core layer and at least one enhanced layer,
wherein the L1 signaling generator generates the first information and the second information in a time interleaving unit determined so as to correspond to a size of each of PLPs included in the core layer.

4 . The transmitting apparatus as claimed in claim 3 , wherein the L1 signaling generator generates the first information based on starting positions of PLPs having the same arrangement order in the respective different layers.

5 . The transmitting apparatus as claimed in claim 4 , wherein in response to the starting positions being different, the L1 signaling generator generates the second information based on a difference in the starting positions of the PLPs having the same arrangement order in the respective different layers.

6 . The transmitting apparatus as claimed in claim 5 , wherein the second information comprises information on a direction being set with reference to a starting position of a PLP included in the core layer among the PLPs having the same arrangement order in the respective different layers.

7 . The transmitting apparatus as claimed in claim 6 , wherein in response to the plurality of PLPs included in the payload being arranged in a transmission order and included in the payload, the L1 signaling further comprises information on a size of each of the plurality of PLPs included in the payload, information on a layer in which each of the plurality of PLPs is included, and information on a PLP having the greatest corresponding degree with respect to the PLP in the core layer from among PLPs in the enhanced layer, the PLPs in the enhanced layer corresponding to one PLP in the core layer.

8 . A receiving apparatus comprising at least one processor configured to implement:
a receiver configured to receive a preamble including L1 signaling and a frame comprising a payload; and a signal processor configured to signal-process the frame, wherein the payload comprises a plurality of Physical Layer Pipes (PLPs), wherein the L1 signaling comprises first information representing an alignment state of starting positions of PLPs included in different layers among the plurality of PLPs and second information representing at least one offset of the starting positions, wherein the signal processor signal-processes a plurality of PLPs included in the payload based on the first information and the second information.

9 . The receiving apparatus as claimed in claim 8 , wherein the L1 signaling further comprises information on an arrangement order of the PLPs included in the different layers and information on the different layers in which the PLPs are included.

10 . The receiving apparatus as claimed in claim 9 , wherein the different layers comprise one core layer and at least one enhanced layer,
wherein the signal processor signal-processes the plurality of PLPs in a time deinterleaving unit determined so as to correspond to a size of each of PLPs included in the core layer.

11 . A method for controlling a transmitting apparatus, the method comprising:
generating L1 signaling; generating a frame comprising a payload in which a plurality of Physical Layer Pipes (PLPs) are included; and transmitting the frame by adding a preamble comprising the L1 signaling in the frame, wherein the L1 signaling comprises first information representing an alignment state of starting positions of PLPs included in different layers among the plurality of PLPs and second information representing at least one offset of the starting positions.

12 . The method as claimed in claim 11 , wherein the L1 signaling further comprises information on an arrangement order of the PLPs included in the different layers and information on the different layers in which the PLPs are included.

13 . The method as claimed in claim 12 , wherein the different layers comprises one core layer and at least one enhanced layer,
wherein the generating the L1 signaling comprises generating the first information and the second information in a time interleaving unit determined so as to correspond to a size of each of PLPs included in the core layer.

14 . The method as claimed in claim 13 , wherein the generating the L1 signaling comprises generating the first information based on starting positions of PLPs having the same arrangement order in the respective different layers.

15 . The method as claimed in claim 14 , wherein the generating the L1 signaling comprises generating the second information based on a difference in the starting positions of the PLPs having the same arrangement order in the respective different layers.

16 . The method as claimed in claim 15 , wherein the second information comprises information on a direction being set with reference to a starting position of a PLP included in the core layer among the PLPs having the same arrangement order in the respective different layers.

17 . The method as claimed in claim 16 , wherein in response to the plurality of PLPs included in the payload being arranged in a transmission order and included in the payload, the L1 signaling further comprises information on a size of each of the plurality of PLPs included in the payload, information on a layer in which each of the plurality of PLPs is included, and information on a PLP having the greatest corresponding degree with respect to the PLP in the core layer from among PLPs in the enhanced layer, the PLPs in the enhanced layer corresponding to one PLP in the core layer.
