Definitions
- the present invention relates to a two-way value-added information service performed using telephone and terrestrial broadcasting, CATV, or satellite broadcasting or other television broadcasting. More specifically, the present invention relates to telephone and still image television broadcasting.
- Background Art The present invention relates to a system and an apparatus for providing an interactive information service by combining television video media such as a television broadcast, a still image video chief, and a still image video disc.
- Videotex system displays characters and images using character codes, not only is the display content limited, but the amount of image information using character codes is smaller than that of natural images. Few.
- the current television system also provides information services such as television shocking, various applications, weather reports, and communication information. Most of the image information required by these information services is still image information, and video information is rarely needed. Therefore, in the current television system that provides these information services, Broadcasts still images as moving images. That is, a still image is displayed on a television screen by transmitting several hundred to one thousand identical screens. Therefore, the transmission cost of still images is extremely high, and there is no directional information service for transmitting still images according to the user's wishes. For example, there is TV shopping as an information service that uses video; conventional TV shopping uses product information transmitted unilaterally by broadcasting stations, so products can be purchased at the discretion of the user.
- one frame is composed of two field screens composed of different screen elements by interlaced scanning.-
- Each of these frame images is a complete natural image
- Field screens cannot be said to be complete natural images due to the amount of information being 12; however, they are satisfactory natural images when compared to screens using character codes. it can.

- a prepaid card such as a magnetic card or an IC card can be used.
- a still image television broadcasting station a satellite TV broadcasting station and a CATV broadcasting station can be used in addition to a terrestrial broadcasting station 8 as shown in Fig. 1, but a plurality of signals are broadcasted. Since it is a still image, it is most desirable to use a CATV broadcast station.
- a tape or a disk on which a still image is recorded can be used as the still image supply means.
- the tape or disk drive device is controlled so that a desired still image can be displayed.
- a still image to be broadcast is transmitted using one frame, but in the case of an image with a small amount of information, the still image is transmitted using one frame per field, that is, 12 frames.
- the various control signals in the above embodiment are transmitted while being superimposed on the scanning lines during the vertical retrace period of the television video signal.
- the audio band of the television audio signal can be used. If the signal is superimposed on the main stand or the main audio band, the signal will be heard by the user, which is annoying.
- ⁇ Control signals generally use digital data.
- dual tone signals In addition to dual-tone telephones as shown in the figure, hals dial telephones, modem telephones or a combination of a personal computer and a modem are used as telephones, and the simplest device uses pulse signals. Pulsed telephones are available, but using dual-tone telephones is the most practical.
- a public telephone line can be used or “the most common power”; if the still image broadcast is a CATV broadcast, CATV times can be used.
- the content of the communication between the user and the information service provider can be displayed on the display device without increasing the burden on the information service provider.
