Abstract
The present invention relates to a method for transmitting and receiving program configuration information for a scalable ultra high definition (UHD) video service under the hybrid transmission environment, and to a method and apparatus for effectively transmitting scalar layer information, and more particularly, the present invention relates to a scheme for inserting group information for the scalable layer of a base layer and an enhancement layer, which form a scalable UHD video, and transmission channel information into a program map table (PMT) or a package configuration table (PCT), and for transmitting same, and to a scalable layer information format for transmitting layer information with a smaller number of bits as possible when a packet header includes scalable layer information.
