ABSTRACT:
A method for updating an electronic service guide (ESG) that includes sending version information of the ESG currently maintained by the server along with ESG data to a terminal. When the server receives an ESG request carrying second version information from the terminal, the server compares the first version information with the second version information and if the first version information differs from the second version information, the server sends the first version information and the ESG data that is related to the ESG requested by the terminal and updated relative to the ESG corresponding to the second version information to the terminal. The present disclosure also discloses a system for updating an ESG, an ESG server and a terminal. With the present disclosure, ESG update is more specific and processing load of the terminal is reduced.
