Abstract

PURPOSE:To obtain a desired video image by extracting, reproducing and broadcasting a corresponding video image medium from a storage part based on the selection information of the medium inputted from a terminal equipment and allowing the terminal equipment to receive and display it so as to have only to input the remote selection command. CONSTITUTION:The selection command of the video medium inputted from a command means 11 of a terminal equipment 1 is stored in a storage means 24, the control means 25 of the broadcast equipment 2 controls the extraction means 22 based on the selection command to extract a corresponding video medium from the storage means 21 and sets it onto a reproducing means 23, controls the reproducing means 23 to reproduce and broadcast the video information from the video medium and a display means 12 of the terminal equipment 1 displays the received information. Thus, a customer has only to input the selection command from a remote location to enjoy a desired video image while keeping sitting down.

Description

[Detailed Description of the Invention] [Summary] A selection instruction for a video medium is inputted from a terminal device having a display means and an instruction means, and the retrieval means of the broadcasting device extracts the video medium from the storage means in which the video medium is stored based on the selection instruction. Since a desired video medium is taken out and set in the playback means, and the playback means plays back the video from the video medium, desired video information can be received by inputting a selection instruction from a remote location.

[Industrial application field]

The present invention relates to a service system for providing video information to customers in remote locations, and particularly to a video service system that allows desired video information to be received by inputting a selection instruction.

In recent years, image information has become increasingly important as a form of information that directly appeals to people's senses, and packaged media such as video discs (hereinafter referred to as discs) have become widespread for entertainment and educational purposes, and the number of media continues to increase. There is. On the other hand, the conventional V
In addition to HF/UHF broadcasting, new broadcasting media such as cable television or CATV are also being implemented. However, since these broadcast media are broadcast unilaterally without the viewer having any choice, especially in CATV systems that use coaxial cables that can transmit large amounts of information, subscribers are required to enter the identification number of the disc, etc. There is a need for a service system that allows users to enjoy desired images by inputting the following information.

[Conventional technology]

Similar methods exist, such as accessing text and image information from a database using the Videotex or Captain System, but this is a practical service method that allows video information to be automatically broadcast by inputting disc selection instructions from a remote location. is considered to have not been developed.

[Problem that the invention seeks to solve]

As described above, the conventional method has the problem that it is labor-intensive and time-consuming because the customer requests service by telephone and the operator operates the video disc device.
