Abstract: A signal transmitting method, a signal transmitting apparatus, and a signal receiving method, and a signal receiving apparatus are discussed, The signal transmitting method according to an embodiment includes encoding ultra high definition (UHD) video data; and encoding signaling information. A service type indicates a UHD digital television service using high efficiency video coding (HEVC). The signaling information includes linkage information. When a linkage type has one of specific values, the linkage type indicates additional linkage information. The UHD digital television service is signaled based on a link type and the linkage type. When a first value of the linkage type is used, an existing service is linked to a target UHD digital television service. 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.
