Plug-and-play network digital image display apparatus and image monitoring system
First Claim
1. A network digital image display apparatus, comprising:
- an Ethernet physical layer chip, for receiving a network packet;
a TCP/IP chip, coupled to said Ethernet physical layer chip, for receiving a network packet transmitted from said Ethernet physical layer chip, and processing said network packet based on a Transmission Control Protocol (TCP) and an Internet Protocol (IP);
a digital audio/video signal processor, coupled to said TCP/IP chip, for receiving and processing a digital audio/video data stream transmitted from said TCP/IP chip;
a display panel, coupled to said digital audio/video signal processor, for displaying a received digital image;
a digital analog/audio controller, coupled to said digital audio/video signal processor, for converting a received digital audio signal into an analog audio signal;
a speaker, coupled to said digital analog/audio controller, for playing a received analog audio signal;
a press key module, coupled to said digital audio/video signal processor, and provided for a user to input an operation instruction; and
a memory, coupled to said digital audio/video signal processor, for buffering an instruction and a data required for the operation of said digital audio/video signal processor.

Abstract
The present invention discloses a plug-and-play network digital image display apparatus plugged into an existing power socket at home or office through a built-in or external powerline to Ethernet adapter and connected to a webcam through a powerline installed at home or office, so that the webcam in a certain room can send captured video and audio signals to the network digital image display apparatus in another room through the powerline, and the network digital image display apparatus plays the image and sound, without the need of installing an additional network cable to achieve the plug-and-play function at the power socket for the environmental dynamic monitoring function. The invention also discloses a plug-and-play image monitoring system, such that a user situated at a place other than a home or an office still can use a personal computer to monitor the home or office through the Internet.
