First Claim
1. A video server capable of communicating with a first video client device and a second video client device, the video server comprising:
- a communication unit for receiving a first video signal from the first video client device and a second video signal from the second video client device;
an image combination unit for combining the first video signal and the second video signal to generate a combined video signal, each combined image frame from the combined video signal comprising at least a part of a first image frame from the first video signal and at least a part of a second image frame from the second video signal; and
an image frame extracting unit for extracting a combined image frame from the combined video signal in response to a grab command received from one of the first video client device and the second video client device, and sending the extracted combined image frame to the one of the first video client device and the second video client device via the communication unit.
