    Abstract: A device for transmitting a media service in a hybrid network, which is a combination of a broadcasting network and a communication network, includes a streaming server, a streaming client, a multiplexer, and a transmitter. The streaming server generates media segments including media data and a metadata file including temporal order information and downloading and reproduction information of the media segments corresponding to a plurality of profiles. The streaming client selects a profile according to a transmission bit ratio appropriate for a broadcasting resource allocation state, requests a media segment with quality that is suitable for the broadcasting resource allocation state from the streaming server, and downloads the same. The multiplexer multiplexes part of information of the metadata file on the profile selected from among the media segment and the metadata file of the plurality of profiles to generate a baseband frame. The transmitter converts the baseband frame into a broadcasting signal and transmits the same through a broadcasting network.

    Abstract translation: 用于在作为广播网络和通信网络的组合的混合网络中发送媒体服务的设备包括流服务器，流客户端，复用器和发射机。 流媒体服务器生成包括媒体数据和元数据文件的媒体片段，包括时间顺序信息和对应于多个简档的媒体片段的下载和再现信息。 流客户端根据适合于广播资源分配状态的传输比特率来选择简档，从流服务器请求具有适合于广播资源分配状态的质量的媒体片段，并且下载它。 复用器将从元数据文件中选择的简档中的元数据文件的部分信息复用到多个简档中的元数据文件以生成基带帧。 发射机将基带帧转换为广播信号，并通过广播网络传输。

    Abstract: Disclosed herein are a method and apparatus for transmitting an 8K Scalable High Efficiency Video Coding (SHVC) service based on broadcast network interconnection. The method includes defining signaling information for the 8K SHVC service, and delivering the defined signaling information to a MPEG Media Transport (MMT)/Real time Object delivery Over Unidirectional Transport (ROUTE) packetizer or to a gateway, separating 8K content into a base layer compatible with a broadcast network and an enhancement layer compatible with a communication network, delivering the base layer from the MMT/ROUTE packetizer to a receiver through the gateway and a transmitter, and delivering the enhancement layer to the receiver through a Dynamic Adaptive Streaming over HTTP (DASH) server.
