ABSTRACT:
This invention relates to a communication system, a data processing apparatus, a data processing method, a data providing apparatus, a data providing method, and a program for offering services to users in response to their requests. Executable buttons representing executable functions are displayed in a given display format, while optional buttons representing optional functions are displayed in a different format. When a download button is operated to request download of software for implementing the function represented by any one of the executable buttons, the software in question is downloaded. Executing the downloaded software changes the optional button representing the implemented function into an executable button on display.
