Description

Multi-Functional Internet Displayphone With A Built-in Home Server And Home Network System Using It}

The present invention relates to a home network system. The home server function, which plays a major role in the home network system, is implemented in the Internet videophone. More specifically, the present invention relates to an internet video telephone with a built-in home server function and a home network system using the same.

A home network is a future home appliance system that allows home appliances such as TVs, refrigerators, and air conditioners to be connected to the homes, kitchens, living rooms, and entrances through the Internet and transmits information to enable operation through mobile phones. . The home network is what constitutes a "digital home," a future home environment where information in the home is connected to the network and services are provided regardless of the device, time, or place.

Currently, home network interface technology is competing with wireless and wired technology. Types of wiring include telephone lines, coaxial cables, UTP, wireless channels and power lines.

Wired technologies include home PNA, IEEE1394, PLC, Ethernet, and wireless technologies include Bluetooth, home RF, and IrDA. Wired home network technology has the advantage of freely sharing information by controlling PC, peripheral devices, information devices, digital home appliances, etc. in a single home with a single protocol.

On the other hand, wireless technology does not require cable wiring and has the advantage of ensuring the mobility of the terminal. In addition, it is easy to change the structure of the network and easier to install and maintain than wired. On the other hand, it is pointed out that the possibility of transmission error due to the interference and attenuation of the same frequency and the security problem.

On the other hand, the definition of the video telephony service is described in CCITT REC.H.100. 'VISUAL TELEPHONE SERVICE' refers to a wideband analog line or digital line for achieving connection between subscriber terminals for the purpose of transmitting moving or still images. It is a two-way communication service using a switched network. In addition, special-purpose one-way systems such as surveillance and information retrieval, or video conferencing services over leased lines, are considered degenerate services for video telephony.

The video and audio outputs of the videophone are converted from analog to digital, coded by codec (coding + decoding) and voice codec, respectively, multiplexed with the dial signal, and then integrated with ISDN (integrated services digital network). Is sent through.

Video telephony technology has developed along with video compression technology. Starting with a video conferencing system called Proshare on the PC from Intel, PictureTel and Polycam have released video communication products using a dedicated line mainly on a wire. Many products used in the PSTN network have been released, but they have not been successful. As the speed of the internet network increases, the bandwidth problem is being solved, but it is not spreading much. Recently, KTF is running a video communication service using a mobile phone using WCDMA high-speed communication technology under the brand of Show.

Core technologies for video telephony are WCDMA and VoIP. Wideband code division multiple access (WCDMA) telephones capable of video calls are in full swing. CDMA is one of the US standards for digital cellular (cellular) phones using spread spectrum technology. There are several advantages of using wideband CDMA over conventional CDMA schemes. First, the wider the bandwidth, the stronger the frequency selective fading, and the higher the bandwidth when transmitting the same data, the higher the processing gain. Dose is increased. Since the multipath can be resolved using the RAKE receiver, even the microcell can overcome the propagation delay in the indoor environment. In addition, it has an excellent bandwidth efficiency per 1MHz bandwidth, which is advantageous in terms of subscriber capacity, and the processing gain is increased, so that the capacity of the power amplifier is reduced to reduce the cost of implementation. have. WCDMA differs greatly from conventional CDMA in terms of the speed of wireless data movement. Although the speed of downloading data is similar to that of CDMA, the speed of uploading data (upload) is much improved. This is directly connected to the video call service. As the frequency band has increased from the existing 800Mhz to 2Ghz, more data can be processed at one time.

Voice over Internet Protocol (VOIP) is a technology that carries voice signals over the Internet. Unlike conventional circuit-switched telephones, voice is transmitted in the form of packets through an IP (Internet Protocol) network, the basis of the Internet. In other words, VoIP refers to a solution related to a technology for delivering voice data to the Internet or IP network, which has been used for data communication, and is an example of an Internet phone. By transmitting voice and data in one network, network efficiency can be improved and various intelligent network services connected to the Internet can be provided. The core technology of Internet telephony is to provide voice services that have been provided through PSTN networks to various services using Internet Protocol (IP). The digitization of voices and the delivery system over IP enable advanced Internet telephony services such as Internet faxing, web calls, and integrated message processing, as well as telephones. Since VoIP technology must be interworked not only in the Internet but also in private IP based networks, public switched telephone networks (PSTNs), or their complex networks, standardization of technologies and protocols is important, and importantly, H.323-based technologies developed by ITU-T. Session Initiation Protocol (SIP) -based technology developed by IETF and IETF, and Media Gateway Control (MEGACO) -based technology jointly developed by ITU-T and IETF to lead the next-generation VoIP gateway market.

In the present invention to implement a home network system, the home server is not in a fixed place, but to implement a home network system that can be easily moved anywhere in the home video phone with a built-in home server function and a home network using the same It's about the system.

In a conventional home network system, a home server is installed at a fixed location in a home. Mainly, wall pads have been installed in the form of grooves formed in walls of living rooms and the like.

In order to solve the problem of the fixedness of the home server, a method of wirelessly inputting home network control to the wall pad using an integrated remote controller has been sought.

However, having an integrated remote control together with such a home server wall pad has been a problem in terms of economics, and even in the case of sending a control signal to the wall pad by a wireless method, the infrared pad is used where the wall pad is not directly visible. If there is an obstacle in the middle, a problem arises. In the case of the radio frequency method, there is a problem of transmission error due to frequency interference and attenuation.

Accordingly, the present invention provides an internet videophone with a built-in home server to solve this problem by connecting an internet videophone with a built-in home server to a telephone line connection terminal (including a network connector) installed in each room of the home. In order to enable home control using a video phone anywhere in the home, the home server itself will be moved.
