2. The apparatus for providing UHDTV service of claim 1 , wherein the television service sorting unit includes a sorting method determining unit configured to determine at least one among a first sorting method that allocates a type of new television service which is different from the first type of the HDTV service and/or a second sorting method that adds a UHDTV stream distinguishing information to a third type for different television service except for the HDTV service among the standard of the HDTV service.

3. The apparatus for providing UHDTV service of claim 2 , wherein the television service sorting unit further includes a new TV service type allocating unit configured to set up the new television service type allocated according to the first sorting method which is received from the sorting method determining unit to a second type of the UHDTV service.

4. The apparatus for providing UHDTV service of claim 3 , wherein the new TV type allocating unit distinguishes a resolution of the UHDTV service, and allocates the new television service type to each resolution, respectively.

5. The apparatus for providing UHDTV service of claim 4 , if the resolution of the UHDTV service is 4K, wherein the new TV type allocating unit sets up the new television service type having a first value which is different from the value of the first type with the second type.

6. The apparatus for providing UHDTV service of claim 5 , if the resolution of the UHDTV service is 8K, wherein the new TV type allocating unit sets up the new television service type having a second value which is different from the value of the first type with the second type.

7. The apparatus for providing UHDTV service of claim 3 , wherein the new TV type allocating unit sets up the new television service type allocated to have a first value which is different from the value of the first type as the second type.

8. The apparatus for providing UHDTV service of claim 7 , wherein the new TV type allocating unit distinguishes at least one of resolution and scanning rate of the UHDTV service using the codec profile (HEVC profile) and/or level which is applied to a component descriptor (component_descriptor) of the UHDTV service in the new television service type.

9. The apparatus for providing UHDTV service of claim 7 , wherein the new TV type allocating unit distinguishes at least one of resolution and scanning rate of the UHDTV service by adding a format distinguishing information to a component descriptor loop of the UHDTV service in the new television service type.

10. The apparatus for providing UHDTV service of claim 9 , wherein the format distinguishing information includes at least one of a stream contents (stream_content) for distinguishing the contents of the video stream of the UHDTV service and a component type for distinguishing a signal format of the video stream.

11. The apparatus for providing UHDTV service of claim 3 , wherein the television service sorting unit further includes an adding unit configured to set up the third type as the second type of the UHDTV service by adding the UHDTV stream distinguishing information to the third type according to the second sorting method which is received from the sorting method determining unit.

12. The apparatus for providing UHDTV service of claim 11 , wherein the UHDTV stream distinguishing information includes at least one of a component type, a codec profile (HEVC profile) and a level.

13. A method for providing UHDTV service in an environment of the UHDTV service and the HDTV service coexist, comprising:

receiving the HDTV service and the UHDTV service;

setting up a type of the UHDTV service as a second type which is different from a first type different of the HDTV service, and

receiving by a television service providing unit a result of distinguishing the HDTV service and the UHDTV service,

wherein both the UHDTV service and the HDTV service are based upon a same digital television channel.

14. The method for providing UHDTV service of claim 13 , wherein setting up the type of the UHDTV service includes: setting up a method for allocating a type of new television service which is different from the first type of the HDTV service as a first sorting method; and setting up a method for adding a UHDTV stream distinguishing information to a third type for different television service except for the HDTV service among the standard of the HDTV service as a second sorting method.

15. The method for providing UHDTV service of claim 13 , wherein setting up the type of the UHDTV service includes setting up the new television service type allocated according to the first sorting method to a second type of the UHDTV service.

16. The method for providing UHDTV service of claim 15 , wherein setting up to the second type includes:

allocating unit distinguishes a resolution of the UHDTV service, and allocates the new television service type to each resolution, respectively;

if the resolution of the UHDTV service is 4K, setting up the new television service type having a first value which is different from the value of the first type with the second type; and

if the resolution of the UHDTV service is 8K, setting up the new television service type having a second value which is different from the value of the first type with the second type.

17. The method for providing UHDTV service of claim 15 , wherein setting up to the second type includes setting up the new television service type allocated to have a first value which is different from the value of the first type as the second type.

18. The method for providing UHDTV service of claim 17 , wherein setting up the new television service type as the second type includes:

distinguishing at least one of resolution and scanning rate of the UHDTV service using the codec profile (HEVC profile) and/or level which is applied to a component descriptor (component_descriptor) of the UHDTV service in the new television service type; or

distinguishing at least one of resolution and scanning rate of the UHDTV service by adding a format distinguishing information to a component descriptor loop of the UHDTV service in the new television service type.

19. The method for providing UHDTV service of claim 14 , wherein setting up the type of the UHDTV service includes setting up the third type as the second type of the UHDTV service by adding the UHDTV stream distinguishing information to the third type according to the second sorting method.

20. The method for providing UHDTV service of claim 14 , wherein the UHDTV stream distinguishing information includes at least one of a component type, a codec profile (HEVC profile) and a level.
