Multi-terminal video interactive middleware device based on shared pool structure

The invention discloses a multi-terminal video interactive middleware device based on shared pool structure. The multi-terminal video interactive middleware device is arranged between a wet site establishment system and a CDN (content delivery network); corresponding of the web site establishment system is respectively sent to a wet site structure data, a program delivery information database and a program information database by an input interface server through a network structure interface module, a column delivery information interface module, a program original data interface module and a corresponding column program information interface module; the databases are respectively called by a wet site structure unified management module, a column delivery information unified management module and a program information unified management module, and respectively delivered by an output interface sever through a web site structure query interface module, a column delivery information query interface module and a program information query interface module; and furthermore, a program information recovery interface module and a user information recovery interface module are arranged and respectively connected with the program information database and a user information database; the user information database is called by a user information unified management module and delivered by a user information interface module and the output interface server.
