PROBLEM TO BE SOLVED: To make it possible to inexpensively, quickly and simply buy and sell many fresh and good products, to reduce losses such as products left unsold because a market is widely spread to all over the country and to supply good products from all over the country to customers. SOLUTION: Plural video cameras 1 are arranged in an auction market to photograph its market conditions at any time and images and sounds are inputted to a video distributor 5, so that present conditions about the production centers, shapes and prices of bid products can be conformed by respective inexpensive video telephones corresponding to the number of distribution ports of the distributor 5 almost simultaneously with the auction market. Each video telephone 7 can be individually connected to the market to be a transmitting source by a secret system, so that an order based on an image and a sound can be transmitted without being known by other persons in the same trade simultaneously connected to the market. Consequently each buyer living in a local district can participate in a bid in a large market through the inexpensive video telephone 7 and the video distributor 5, directly bid for a remote local market or a directly order products to a producer. |
