PROBLEM TO BE SOLVED: To simplify equipment configuration and processing and to facilitate the transmission of commercial message program in a data transmitter to be used for NVOD. SOLUTION: Partial AV data dividing AV data to be distributed every prescribed reproducing time are repeatedly distributed to respective channels when the data is transmitted. Then, the data are received while successively selecting those channels on the reception side so that the entire AV data can be viewed. Since it is enough for respective channels just to process one part of those AV data, equipment configuration and processing procedure can be simplified for both the transmitter and the receiver. Thus, the commercial message program can be reproduced together with a main program in the reception while being sent through the dedicated channel, the independency of commercial message program is improved and handling is facilitated. |
