'Liānbō' literally combines 联 (lián), meaning 'to link' or 'joint', and 播 (bō), meaning 'to broadcast'. Together, they form a noun referring to a simultaneous broadcast of the same program across multiple media outlets—such as TV stations, radio networks, or online platforms—coordinated in real time. It emphasizes synchronization and collaboration rather than independent transmission.

This term is commonly used in China’s media landscape, especially for major national events like the CCTV News 'Xinwen Lianbo' (News Simulcast), where provincial stations air identical content at the same time. While it can apply to radio or digital streams, it most frequently appears in television contexts and carries institutional connotations—often implying official or centralized coordination rather than casual or commercial cooperation.
