Information processor, information processing method as well as broadcasting system and broadcasting method

An information processing method for processing electronic program guide information having program descriptions therein, comprising the steps of:

• receiving at least electronic program guide information having program descriptions therein, and
• inserting into said program descriptions of said electronic program guide information identification codes for identifying key words of said program descriptions;
• wherein upon receipt of said electronic program guide information including said identification codes, said electronic program guide information is stored in a table according to said identification codes,
• said program descriptions comprise at least text information, and
• said identification codes comprise identifiers for identifying the position of the key words within said program descriptions of said text information, and classification information for classifying each of the key words.

An information processor for processing transmitted data including electronic program guide information having program descriptions therein and identification codes inserted in said program descriptions of said electronic program guide information for identifying key words of said program descriptions, comprising:
