<P>PROBLEM TO BE SOLVED: To reduce an arithmetic throughput in a base station or a communication server that relays data, and to enhance efficiency in the use of a communication network when transmitting/receiving the data among a plurality of spots via the communication network. <P>SOLUTION: In the communication terminal equipment of a data receiving side, a control part 12 generates a control signal designating a format of data set by an operation input from an operating part 11 and transmits the control signal from a communication part 16 to the other communication terminal of a data transmitting side. In the data transmitting side communication terminal equipment, the format of the data to be transmitted is determined in an image processing part 14 and a data converting part 15 on the basis of the received control signal, and transmission data are converted into the designated format and transmitted from a communication part 16 to the data receiving side communication terminal equipment. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
