The media content may include a sequence of one or more periods. Each of the periods may include one or more representations. The metadata may include information used to describe a relationship between the representations, and include information for terminals having different display bit depths. ## Claims ### Claim 1 A method for providing media content performed by a DASH (Dynamic adaptive streaming over HTTP) client, the method comprising: receiving metadata of media content, the metadata comprising one or more periods; and accessing segments of the media content based on information provided by the metadata, wherein the each of the periods includes one or more adaptation sets, wherein the adaptation set includes one or more representations, wherein the representation includes one or more sub-representations, wherein the adaptation sets, representations, and sub-representation share common attributes and elements. ### Claim 2 (depends on 1) The method of claim 1, wherein the all representations included in a single adaptation set represent the same media content components, and include one or more media streams that are determined to be perceptually equivalent. ### Claim 3 (depends on 1) The method of claim 1, wherein one or more representations are arranged in an adaptation set based on properties of media content components present in the representations. ### Claim 4 (depends on 1) The method of claim 1, wherein the properties of the media content components include at least one of: 1) an attribute related to language, 2) an attribute related to a media component type, 3) an attribute related to a picture aspect ratio, 4) an element related to a role property which specifies information on a role annotation scheme, 5) an element related to an accessibility property which specifies information on an accessibility scheme, 6) an element related to a viewpoint property which specifies information on a viewpoint annotation scheme, and 7) an element related to a rating property which specifies information on a ration rating scheme. ### Claim 5 (depends on 1) The method of claim 1, wherein the information included in the at least one of the representations indicates an intended use of the at least one of the representations, and the intended use comprises at least one of a sign language, a subtitle, a caption, or a description. ### Claim 6 A method for providing media content performed by a server, the method comprising: performing hosting on a DASH (Dynamic adaptive streaming over HTTP) segment; and transmitting metadata of media content to a client, the metadata comprising one or more periods wherein each of the periods comprises one or more representations of the media content, wherein the each of the periods includes one or more adaptation sets, wherein the adaptation set includes one or more representations, wherein the representation includes one or more sub-representations, wherein the adaptation sets, representations, and sub-representation share common attributes and elements. ### Claim 7 (depends on 6) The method of claim 6, wherein the all representations included in a single adaptation set represent the same media content components, and include one or more media streams that are determined to be perceptually equivalent. ### Claim 8 (depends on 6) The method of claim 6, wherein one or more representations are arranged in an adaptation set based on properties of media content components present in the representations. ### Claim 9 (depends on 8) The method of claim 8, wherein the properties of the media content components include at least one of: 1) an attribute related to language, 2) an attribute related to a media component type, 3) an attribute related to a picture aspect ratio, 4) an element related to a role property which specifies information on a role annotation scheme, 5) an element related to an accessibility property which specifies information on an accessibility scheme, 6) an element related to a viewpoint property which specifies information on a viewpoint annotation scheme, and 7) an element related to a rating property which specifies information on a ration rating scheme.
