Abstract: Disclosed are a dynamic multi-mode service (MMS) transmission apparatus, a dynamic MMS reception apparatus, and a method for providing a dynamic MMS. The method includes generating, by the dynamic MMS transmission apparatus, signaling information including information about linkage between service channels based on broadcast schedule information about a broadcast service; transmitting, by the dynamic MMS transmission apparatus, the signaling information and the broadcast service to the dynamic MMS reception apparatus through at least one of a broadcast network and a broadband network; receiving, by the dynamic MMS reception apparatus, the signaling information and the broadcast service; interpreting, by the dynamic MMS reception apparatus, the information about the linkage between service channels, included in the signaling information, by decoding the signaling information; and providing, by the dynamic MMS reception apparatus, the broadcast service by performing dynamic channel switching based on the information about the linkage between service channels.

Abstract: Disclosed herein are a method for broadcast gateway signaling using a cloud network and an apparatus for the same. The method includes generating an outer packet corresponding to the outer layer of a tunneling system using an inner packet corresponding to the inner layer of the tunneling system, generating a header of the outer packet, and transmitting the outer packet to a transmitter through a Studio-to-Transmitter Link (STL). The header includes an STL propagation delay time field indicating a reception wait time for an STL stream corresponding to the outer packet.
