  • Teletext decoder and television receiver provided with a teletext decoder
    Patent number: 5410359

The teletext pages with the searched keyword, or their page numbers, are identified and stored for later display or selection. The receiver has arrow keys for selecting the keyword on the display screen so that an alphabetical keyboard is not necessary.
