Claim:
1. A signal transmitting method comprising: encoding ultra high definition (UHD) video data by an encoder; encoding signaling information comprising service description information by a signaling information encoder, wherein the service description information includes a first information having a service type, and the service type specifies a type of a service, wherein when the service type has a specific coded value, the service type indicates a UHD digital television service using high efficiency video coding (HEVC), wherein the service description information includes a second information, and the second information includes information on characteristics of the encoded UHD video data, wherein the signaling information includes event information and the event information includes linkage information, wherein the linkage information includes a linkage type, and when the linkage type has one of specific values, the linkage type indicates additional linkage information, wherein the additional linkage information includes link type information which indicates a type of a linked service, wherein the UHD digital television service are signaled based on a combination of values of a link type and the linkage type, wherein when a first value of the linkage type is used for the additional linkage information, an existing service is linked to a target UHD digital television service, and wherein when a second value of the linkage type is used, a UHD digital television service is linked to an existing service including a high definition or 3D service; and multiplexing the encoded UHD video data and the signaling information by a multiplexer; and transmitting the multiplexed data by a transmitter.
