The invention provides an information providing apparatus and method by which the amount of data to be transmitted when data of a program table composed of characters and images or the like are to be transmitted is reduced and it is made possible to cope with a change in contents of data rapidly. Data of an electronic program guide to be provided is hierarchized into data (A1 data) which may possibly be changed such as the broadcasting date, the start time and the end time, data (A2 data) which are not changed at all such as a program name, and data (A3 data) composed of still pictures, moving pictures, voice and so forth which have comparatively large data amounts, and for each medium, data of a hierarchy suitable for the medium is provided. Each A3 data is referred to by one or a plurality of A2 data, and each A2 data is referred to by one or a plurality of A1 data. |

DETAILED DESCRIPTION It is an object of the present invention to provide an information providing apparatus and method, a display controlling apparatus and method, an information providing system and a transmission medium by which the amount of data to be transmitted when data of a program table composed of characters and images or the like are to be transmitted is reduced and it is made possible to cope with a change in contents of data rapidly.
In order to attain the object described above, according to an aspect of the present invention, there is provided an information providing apparatus, comprising hierarchizing means for hierarchizing electronic program guide information to be provided into first information which designates predetermined information and second information to be referred to by the first information, first providing means for providing at least one of the hierarchized first information and second information, and second providing means for providing layout information from within the electronic program guide information which relates to a layout when the electronic program guide information is to be displayed on a screen.
According to another aspect of the present invention, there is provided an information providing method, comprising the steps of hierarchizing electronic program guide information to be provided into first information which designates predetermined information and second information to be referred to by the first information, providing the hierarchized first information or second information, and providing layout information from within the electronic program guide information which relates to a layout when the electronic program guide information is to be displayed on a screen.
According to a further aspect of the present invention, there is provided a transmission medium which transmits a program, the program including the steps of hierarchizing electronic program guide information to be provided into first information which designates predetermined information and second information to be referred to by the first information, providing at least a one of the hierarchized first information or second information, and providing layout information which relates to a layout when the electronic program guide information is to be displayed on a screen
