ABSTRACT:
Television receiver apparatus is disclosed for receiving and selectively displaying a video picture derived from video signals transmitted on a broadcasting channel, or alphanumeric data information derived from alphanumeric data signals which are transmitted during at least one horizontal line interval in each video frame interval. A predetermined number of alphanumeric data programs are transmitted on a given broadcasting channel, with each alphanumeric data program being comprised of alphanumeric data signals and an alphanumeric data program identification code. An entire alphanumeric data program is transmitted over a number of frame intervals. The television receiver apparatus includes an alphanumeric data program separator for separating the alphanumeric data signals and the alphanumeric data program identification code from the received broadcasting channel. A memory stores all of the alphanumeric data program identification codes transmitted on the received broadcasting channel; and a write-in circuit writes each of the alphanumeric data program identification codes into the memory, and a read-out circuit reads out each of the stored alphanumeric data program identification codes. A display device, such as the display screen of the television cathode ray tube, displays the alphanumeric data program identification codes which are read out of the memory. In accordance with one embodiment of this invention, the particular one of the displayed alphanumeric data program identification codes which then is being received by the television receiver apparatus is indicated. In accordance with another embodiment, any of the displayed alphanumeric data program identification codes may be selected such that the alphanumeric data information contained in that program is displayed, and the selected alphanumeric data program identification code is displayed distinctively.
