DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates in general to broadcast media which includes radio and television and to apparatus and methods for obtaining information for transmitted programs.
BACKGROUND OF THE INVENTION
A listener of radio may hear a song of interest and decides to buy it, but does not know the title or artist. Frequently the announcer of the radio station does not state the title, artist or other information of the song, or even if the information was announced, it was before the song played. The listener must wait until the song is heard again and hope that the title and artist are announced after the song. Even when the information of the song are announced and heard, there are situations where such information cannot easily be retained (such as when a listener is operating an automobile or simply when a listener does not have something to write on or write with).
The problem is especially true for commercials, for which the listeners usually must memorize information that are difficult to memorize, such as telephone numbers and addresses for ordering the products advertised. If listeners fail to remember these items of information, the effects of the commercials are diminished.
Similarly, a viewer of television may be scanning through different channels or stations and start watching a program that is already in progress. After a few minutes, the viewer may decide to view the show the next time it is on, because the viewer wants to see it in its entirety or the viewer may be watching something else. Therefore, the viewer must physically search through the current and subsequent TV program listings until the next showing of the program is found. This is time consuming and if several months pass, the viewer may forget the name of the show.
Despite the above described long-felt inconvenience to so many in the audience, no satisfactory solution has so far been found.
Another problem is the high cost of advertisements. An advertiser may only be able to finance a half-minute prime time commercial on television or radio. If a less expensive alternative communication channel is available for providing additional information (e.g. price quotes, store hours, details of a product, etc.) to listeners, the advertiser can then have more flexibility on how to spend the limited time and money available for media commercials. The listeners would access other information using the less expensive alternative communication channel.
The same alternative channel is also needed for newspapers and magazine advertisements which have a limited lifetime. For example, the Sunday paper real estate section typically lists homes which may only be available for viewing on that day. If a second channel of information is available, then information about the home can still be available to the readers even when the advertisement is taken off.
Despite the above identified economic benefits, a satisfactory and less expensive alternative channel of communication has yet to be found.
Prior art systems in this regard all require a station to broadcast the information in a secondary signal, concurrently with the broadcasting of the main program, and the listeners must be equipped with special decoder circuits for recovering the information. For example, the European radio broadcast systems (RDS) broadcast the identification of a program in the SCA band and require the listeners to have special receivers to decode and display this identification.
There is also a proposal to transmit identification of a television program during the vertical blanking interval (VBI) period. Unfortunately, special decoders are also needed under such method.
In a system described in patent application Ser. No. 07/806,152, filed Dec. 11, 1991 (incorporated herein by reference as though set forth in full), auxiliary information relating to a broadcast program or printed material is retrieved using a code which is broadcast or printed along with the program or print material. The code number is used for delayed recording from a television or a ra
