Video network server for distributing sound and video image information to a plurality of terminals

A video network server which distributes sound/video image information to a plurality of terminals comprising:

• a network system status obtaining section for obtaining status of a video network system including a video network server, a network and terminals;
• a network system status decision section for deciding the status of the network system which is obtained by the network system status obtaining section;
• a parameter computing means for computing parameters including a number of terminals which the system may allow on the basis of a result which is decided by the network system status decision section;
• and
• a parameter setting means for setting parameters of the system on the basis of a result which is computed by the parameter computing means.

A video network server which distributes sound/video image information to a plurality of terminals comprising:

• a data storage means for storing data;
• a buffer memory for temporarily storing data when the data which is requested by a terminal is transferred;
• a parameter computing means for allocating a given time interval in a period which is allocated for a terminal for another terminal when it is possible to read data which is requested by the terminal in a time which is less than a given time interval in a predetermined period;
• a data prereading means for reading the data which is requested by the terminal for a given time interval in a period which is allocated by the parameter computing means from the data storage means and outputting the data to the buffer memory;
• and
• a data feeding means for feeding the data which is output to the buffer memory to the terminal.
