System and method of providing television program sharing service

Disclosed is a system and method of providing a TV program sharing service that enables sharing of a TV program among EPG-based TV sets and/or set top boxes, and thus enables recording of the already broadcast program whenever a user desires to do so. The system includes a TV client for directly uploading a program stored in its own storage device to another TV client, or for directly downloading a program stored in a storage device of another TV client to itself, and a shared program management center for storing record information of the programs stored in the TV clients in its own database, and enabling a mutual transfer of the programs among the TV clients using its database.
