1. A display device, which can directly connect to a network, comprising:
- an interface circuit, which is connected to a communication line through which an information packet including image information, control information, and header information indicating sender and receiver addresses of said information is transmitted, and which fetches said information packet from said communication line;
an image signal processing circuit connecting to said interface circuit for producing image signals based on the image information contained in said information packet;
a control circuit connecting to said interface circuit for controlling operation of said image signal processing circuit according to the control information contained in said information packet provided from said interface circuit without instruction which is received on the display device independently; and
a display panel for displaying image based on said image signals produced by said image signal processing circuit, wherein said interface circuit, to which is assigned an inherent address unique within the network, detects a match between the inherent address and the receiver address of said header information and identifies the sender address of said header information to permit display of images with specific addresses.

Abstract
A networked camera includes an I/F circuit so that it can be directly connected to a communication line L of the network. A computer connected to the network can control the imaging operation of the camera independent of any other computer. A desired network address can be attached to image data to send to the communication line L, and image data can be transferred to any other computer or device connected to the communication line L.

3. A network system comprising:
-
a communication line for transmitting an information packet which includes image information, control information, and header information indicating sender and receiver addresses of said information;
at least one terminal device, connected to said communication line, which drives an authoring software to generate said image information, generates said information packet in which the header information indicating the own address uniquely assigned over the network and the receiver address is added to the generated image information, and sends out the generated information packet to said communication line; and
a display device, connected to said communication line, which fetches said information packet from said communication line based on said receiver address of said header information, and displays the images corresponding to said image information according to said control information without instruction which is received on the display device independently, wherein said display device, to which is assigned an inherent address unique within the network, includes an interface circuit which detects a match between the inherent address and the receiver address of said header information contained in said information packet transmitted through said communication line to permit capturing of the information packet, wherein said display device further includes a control circuit connecting to said interface circuit for controlling operation of said display device according to said control information provided from said interface circuit. - View Dependent Claims (4, 5, 6)
