Abstract

A method and apparatus for transmitting and receiving digital broadcasting. The method includes transmitting and receiving main broadcast data and supplemental broadcast data, wherein the main broadcast data is able to independently provide a basic broadcast service and the supplemental broadcast data is able to provide an extended broadcast service in combination with the main broadcast data, by using methods that are different from each other and thus the extended broadcast service may be provided.

Description

technical field [0001] Methods and apparatuses consistent with the exemplary embodiments relate to transmitting and receiving digital broadcasting, and more particularly, to a method and apparatus for transmitting and receiving data for providing extended broadcasting services. Background technique [0002] The Advanced Television Standards Committee (ATSC) Digital Television (DTV) High Definition (HD) service is a DTV standard used in Korea and the United States. Currently, in Korea, services in one transmission band (ie, HDTV services with a resolution of 1920×1080i) are provided at 6 MHz at a speed of 19.395 Mbps. In this regard, high-quality content can be provided to viewers; however, a large number of services including various contents cannot be provided. [0003] At the request of users wishing to receive a large number of services, some broadcast providers have considered adopting multi-mode services (MMS), in which additional services are guaranteed by degrading t...
