Embodiment Construction

[0030] The UPnP network protocol will be described in detail below first.

[0031] At present, with the rapid popularization of home networks, the existing personal computer-based network environment in each family is gradually changing to an environment that uses diversified next-generation network technologies, making personal computers (PCs), application products, wireless devices, etc. Home appliances urgently need a technology that can enjoy the Internet world in an independent and unified manner by using the IP network protocol. Accordingly, the technology developed by MS (Microsoft Corporation) and the Plug and Play Forum (Forum) is UPnP™ (hereinafter referred to as UPnP) technology.

[0032] On the basis of decentralized and open network structure, UPnP technology enables home appliances in the home network to use a peer-to-peer network without central management. At this time, the components of the decentralized and open network structure in UPnP technology adopt sta...

Abstract

This invention relates to one wireless image system and its control method by use of plug-in type, which comprises the following steps: loading UPnP network agreement television socket box to search index information to send self IP address and to receive MPEG files transmission order and then MPEG files and channel information to receive channel switch order channel and relative MPEG files and current switch channel information; loading UPnP network agreement intelligent displayer to send index information by circle by multiple point to receive television socket box IP address and to send MPEG files order or channel switch order to process the files codes and to display it onto LCD screen through user UI.

Description

(1) Technical field [0001] The invention relates to the technology of the wireless image system, in particular to a wireless image system adopting a plug and play (UPnP) mode and a control method thereof. (2) Background technology [0002] At present, among the product functions of LG Flatron Air in South Korea, there is a wireless TV (TV) function. [0003] Here, in order to demonstrate wireless TV functionality, the above product will be composed of a smart display and a TV cradle box. [0004] The TV base box encodes the TV signal into an MPEG file, and then transmits it to the smart display through a wireless LAN. [0005] The smart display above decodes the MPEG file transmitted from the TV base box, and displays it on the screen of the liquid crystal display. [0006] To do this, the smart displays mentioned above need a network protocol that can control the functions of the TV. [0007] That is, the start and end of TV functions and channel control functions in the...
