COMMUNICATION TERMINAL AND COMMUNICATION METHOD FOR EXCHANGING CONTENTS
First Claim
1. A communication terminal forming a contents exchange system, comprising:
- a communication device;
an operation unit receiving an input of an instruction to said communication terminal;
a memory; and
a controller for controlling an operation of said communication terminal;
whereinsaid communication device communicates, to/from another communication terminal, request information requiring a response, response information representing the response, content data representing content as at least one of image and voice, and determination information defining whether said content data is to be an object of transmission;
said memory stores said content data and said determination information; and
said controller causes another communication terminal included in said contents exchange system to repeatedly transmit said request information to said communication device,when the response information transmitted from said another communication terminal in response to said request information is received by said communication device, causes said communication terminal that transmitted said response information to transmit said determination information to said communication device,when said request information is received from said another communication terminal, causes said communication device to transmit said response information and said determination information to said another communication terminal,when said communication device transmits said determination information and determination information different from that transmitted by said communication device is received by said communication device, determines whether said content data is to be transmitted or not, based on the determination information transmitted by said communication device and the determination information received by said communication device,causes said communication device to transmit the content data determined to be transmitted, andwhen content data different from the transmitted content data is received by said communication device, stores in said memory said received content data and the determination information on said received content data;
said communication terminal further comprisingan output device for outputting said content.

Abstract
Opportunity of enjoying video and music is enlarged. A content reproducing device is used in a contents exchange system including a plurality of contents reproducing devices. The content reproducing device includes a short range communication unit, a memory, a control unit, and a speaker. The short range communication unit communicates request information, response information, content data and flag information to/from content reproducing devices. The control unit controls the short range communication unit so that content data is transmitted. The control unit controls the memory such that the content data and the flag information received by the short range communication unit are stored.

15. A method of exchanging contents, comprising the steps of:
-
repeatedly transmitting request information requiring response; receiving response information representing said response, transmitted in response to said request information; transmitting determination information for determining whether content data representing a content that is at least one of image and voice is to be an object of transmission or not, to the transmitter of said response information; transmitting said response information and said determination information to the transmitter of said request information; when said determination information is transmitted and determination information different from said transmitted determination information is received, determining whether said content data is to be transmitted, based on said transmitted determination information and said received determination information; transmitting the content data determined to be transmitted; when content data different from said transmitted content data is received, storing said received content data and determination information on said received content data; and outputting content based on the stored content data.
