Abstract: PURPOSE: A method for managing a shared state using delay prediction in distributed virtual environment is provided to be suitable for client-server based distributed virtual environment and secure an impartial service to network users with inter-different bandwidths through the delay prediction. CONSTITUTION: It is confirmed whether an event is generated by an event packet received from a server or an event is generated in a client itself for judging an event type(301). If the event is generated by the event packet received from the server, maximum transmission delay from the server to an other client is extracted from the last field of the event packet and the extracted maximum transmission delay is stored in a database(320)(302). A transmission delay time from a server computer to client computers is calculated using a received time of the event packet and an event generation time in the event packet, and the calculated transmission delay time is stored(303). The calculated transmission delay time is attached to the event packet(304), and the event packet is transmitted to the server(311). If the event is generated in the client itself, a real value is obtained from a real model(305) and a prediction value is obtained from a prediction model stored in the database(320)(306). The difference between the obtained real value in the real model at current time and the prediction value in the prediction model of the client computer having the maximum transmission delay is calculated from obtaining a prediction error(307). If the prediction error is more than an other threshold value according to the various application of the client computers(308), the prediction model is corrected(309). The corrected content is attached to the event packet(310), and the event packet is transmitted to the server computer through a network(311).

IPC: H04N5/781
Filed: 2000-12-13
Abstract: PURPOSE: To enable a shutter button to be operated even before a disk is turned into recordable state and to make recognizable the number of recordable data. CONSTITUTION: Every time when compressed image data for one piece are completely recorded on a memory card 34, the free capacity value of a disk 34c is written on a flash memory 34d by a controller 34a. When next turning on a power source, this free capacity value is read out by an instruction from a CPU 36. When the free capacity of the disk 34c is less than the free capacity of a compressed image area 24a, the CPU 36 invalidates the free capacity of the compressed image area 24a exceeding the free capacity of the disk 34c. Thus, the number of photographable pictures is limited. Besides, the CPU 36 calculates the number of recordable pictures on the basis of the read free capacity value and displays the calculated number of recordable pictures on a display 48.
