Abstract:
A video distribution system which is enhanced in flexibility in distribution mode switching. In a camera server connected to a viewer via a network, a video capture board captures a video image. A CPU processes the captured video image according to an electronic PTZ mode for cutting out a part of the captured video image and a mechanical PTZ emulation mode for cutting out parts of the captured video image and interpolating the cut-out images. The CPU distributes the processed video image to the viewer via the network. The CPU performs mode switching between the electronic PTZ mode and the mechanical PTZ emulation mode based on control information transmitted from the viewer.
