SYSTEM FOR TRANSMITTING VIDEO INFORMATION}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video information transmission system, and more particularly, to a video information transmission system capable of simultaneously transmitting video information of a personal computer to a television receiving video information from a broadcasting station.

In recent years, as the information society is rapidly entering, it is possible to easily obtain information in all fields such as society, culture, economy, and sports through the Internet using a computer for general households, and the most common video media in daily life. In-person TV broadcasting has also become an age when satellite communication systems can be used to easily access events and other information around the world at home through satellite broadcasting systems.

As such, the home shopping business using the Internet has emerged as one of them, and the era of electronic shopping through full-fledged broadcast media has come.

In the era of electronic shopping, the size of the market has increased rapidly in response to market demands such as the increase of dual-working couples, transportation problems, low prices, and the constraints of time and space.

Therefore, the general public obtains e-shopping mainly through advertising media such as television broadcasting or the Internet, which provides information on new products, and in some cases through publications.

However, most of the general public advertises their products through commercial broadcasting, or advertises products through a separate home shopping channel, and makes their homepage on the Internet to advertise their products.

Among them, the advertisement through broadcasting is to purchase and order a product by calling the phone number displayed on the screen if the user wants to purchase and watch the shopping advertisement on the broadcasting screen of the channel where the home shopping service of the viewer is provided, or the advertisement through the Internet. The user purchases a product by inputting orders for a product to be purchased by viewing an advertisement of a product provided on a homepage that provides a home shopping service on the Internet.

In addition, since the advertisement provided through the air broadcasting stimulates visual and auditory effects, it is effective, but the disadvantage is that the advertisement is one-time and the advertisement time is short. The advertisement through the Internet provides advertisements in various forms and Information can also be provided in relatively detail, so that a buyer can easily purchase information on a specific product at any time with a simple search, but there is a disadvantage in that a variety of objects can be freely accessed yet.

Recently, with the development of digital television technology and internet broadcasting technology, broadcasting stations have been able to provide various information to subscribers in the data area, and subscribers can obtain useful product information by using the data provided in the data area. As the present situation, the subscribers select the program menu of the digital television broadcasting program, and the subscribers can search various menus and select and watch the desired broadcasting program among them. Hotel tickets can be booked in a convenient way.

As described above, the commercial, home shopping channel, digital television broadcast, and internet broadcast can be conveniently used by a viewer as a subscriber to search and select a broadcast program, various information, and purchase of a product. Unlike the broadcast media, the current method of accessing the homepage and placing an order is used.

Therefore, in the case of shopping using the Internet, there is a problem in that shopping through the Internet can not be performed at all when the computer is not used or the user is not familiar with the use.

Accordingly, an object of the present invention is to display various information provided to a personal computer from an information supply server when watching a television broadcast program at home together with the broadcast program, so that various information can be easily obtained and used when watching television. have.

In order to achieve the above object, the present invention provides a broadcasting station for producing a broadcast program and transmitting it to each home through airwaves, cables, and satellite media; An information service server that receives, edits and produces various types of information from the broadcasting station or various information providers and provides the information through an internet communication network; A personal computer displaying information provided from the information service server; A PC set-top box for converting various video data signals of the video graphics array into television video signals from the personal computer; A TV multiplexer for combining the video signal from the PC set-top box with the video signal transmitted from the broadcasting station; A television for displaying the broadcast program video signal and the PC video signal combined from the TV multiplexer; Remote control for selecting and remotely controlling the information provided while remotely controlling the program broadcast on the television.

Therefore, according to the present invention, the broadcast program transmitted from a broadcasting station via a television, as well as the information provided to the personal computer from an information service server is provided with the broadcast program, so that the viewer of the broadcast program is accompanied by Information can be viewed and Internet shopping can be done through the television.
