Method of receiving time-specified program contents

In a method of distributively transmitting at least program information comprising a distributive transmission date and time, and program contents which will be transmitted on the distributive transmission date and time through a network, a method of receiving time-specified program contents, comprising the steps of:

• receiving the program information from a program management server in which the distributive transmission date and time, and an address of a distributive transmission server are registered;
• registering the program information obtained from the program management server through the network;
• comparing the distributive transmission date and time on subsequent acquisition dates and times with the distributive transmission date and time on prior acquisition dates and times upon every access to said program management server to detect whether the distributive transmission date and time have updated in said program management server;
• rewriting the distributive transmission date and time to reflect any changes in the distributive transmission date and time registered in the program management server from prior acquisition dates and times;
• accessing a program contents server on the registered distributive transmission date and time to receive and reproduce the program contents for reproduction thereof;
• and
• receiving advertisement contents from an advertisement presentation server prior to or synchronously with receiving the program contents to reproduce the advertisement contents.

In a system for distributively transmitting at least program information comprising a distributive transmission date and time, and program contents which will be transmitted on the distributive transmission date and time through a network, a system for presenting time-specified program information, comprising:

• a program management server having program information in which at least the distributive date and time and an address of a distributive transmission server are registered;
• a program contents presentation server for distributively transmitting the program contents;
• program information setting management means for registering therein the program information obtained from the program management server through the network, said program information setting management means comprising means for comparing the distributive transmission date and time on subsequent acquisition dates and times with the distributive transmission date and time on prior acquisition dates and times upon every access to said program management server to detect whether the distributive transmission date and time have updated in said program management server, and means for rewriting the distributive transmission date and time to reflect any changes in the distributive transmission date and time registered in the program management server from prior acquisition dates and times;
• and
• means for accessing the program contents presentation server on the distributive transmission date and time the information of which has been obtained from the program information to acquire the program contents to reproduce the program contents thus acquired.

A storage medium storing therein a program which receives at least program information containing a distributive transmission date and time, and program contents which will be transmitted on the distributive transmission date and time through a network, said program comprising the steps of:

• receiving the program information from a program management server in which the distributive transmission date and time, and an address of a distributive transmission server are registered;
• registering the program information obtained from said program management server through said network;
• comparing the distributive transmission date and time on subsequent acquisition dates and times with the distributive transmission date and time on prior acquisition dates and times upon every access to said program management server to detect whether the distributive transmission date and time have updated in said program management server;
• rewriting the distributive transmission date and time to reflect any changes in the distributive transmission date and time registered in the program management server from prior acquisition dates and times;
• accessing a program contents presentation server on the distributive transmission date and time;
• and
• reproducing the program contents obtained from said program contents presentation server.
