<P>PROBLEM TO BE SOLVED: To provide a server that can make the streaming distribution of video data in optimum conditions regardless of communication conditions and a mobile terminal that can receive video data under the optimal conditions. <P>SOLUTION: Under a normal condition, the streaming distribution of video data is performed from a distribution device 1 to a mobile terminal 2 using a traffic channel that a traffic channel allocation section 11 assigns. If a real-time process request section 22 of the mobile terminal 2 requires the real time processing of the video data at this time, a real-time assuring section 13 of the distribution device 1 informs a channel allocation section 12 to hold the assignment of a specific channel. If a receiving condition check section 24 of the mobile terminal 2 sends receiving condition deterioration information to the distribution device 1, a terminal receiving condition determination section 14 of the distribution device 1 instructs the channel allocation section 12 to make the synchronized switching of the video data from the traffic channel to the specified channel when the deterioration is large. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
