| Abstract: | To achieve the goal of issuing and obtaining EPG information under cable TV network environment, EPG service nodes are abstracted from EPG service devices and a tree - structured EPG issue system is raised based on logical hierarchy of these nodes. This system realizes regional and layered issue of EPG information as well as individuation. Project results suggest that this system solves unified EPG issue of interactive TV service efficiently and improves service management of the system. |
