In the method of the present invention, a customer of a service provider would be placed in hold while waiting to speak to a customer service representative. The method and system of the invention would recognize the telephone number of the caller using a “caller ID” system. If this call is the first time the caller has ever called, the caller would be presented with an audible listing of listening choices that would include but not be limited to the latest news, the weather (of the caller's location), financial headlines, or a selection of music stations (via cable radio, for example). The caller would then speak or type his / her preference into the keypad and the selection would be played. If the caller does not like the selection, the caller can then speak another selection or type the new selection as many times as the caller prefers. The caller selection is recorded in a caller preference database. Finally, when the same customer calls one or more additional times, the system would retain the caller's number and preferred listening selection, based on caller ID value. The listening selection would automatically be played on subsequent calls.

A master guide table for a digital broadcast protocol, and a method of broadcasting and updating an electronic program guide using the table, uses identification information included in a bit stream syntax of the master guide table to classify whether contents of an event information table are merely shifted in time, or are actually changed. The master guide table is transmitted in accordance with a program and system information protocol (PSIP) for an advanced television system committee (ATSC) defined standard digital television broadcast protocol. A digital television receiver of a receiving party, or a digital cable broadcast receiver, can determine whether the contents of the event information table EIT are merely shifted in time or actually changed by parsing the identification information in the master guide table MGT. If the parsed contents of the identification information indicate that the event information table contents are merely shifted in time without any change, then a database maintaining previous event information table is not updated. Accordingly, time wasted in unnecessarily updating the database can be decreased.
