Title: Integrated web-based instant messaging apparatus used as a video phone

Description:
BACKGROUND OF THE INVENTION 
     As internet infrastructure has experienced rapid development, telecommunication through network becomes more feasible and available for business and ordinary consumers. High speed internet accesses, supported by broadband or digital subscribed line (DSL) services which are shared with respective cable TV and phone lines, are already penetrating more and more residential customers. The trend may be sustained with recent development of optical application into telecommunication, which dramatically speed up data processing or flowing by using light of pulse through light circuit or fiber, instead of sending electrons over metal interconnector or wires. Examples are progresses in worldwide FTTP (Fiber To The Premise) projects and recent IBM&#39;s super fast optical chipset prototype reaching 160 Gigabites data transfer rate. Fast connectivity rate for data, voice and video through network will improve quality of audio/video communication over the Internet, therefore attract more households to subscribe the high-speed Internet access for on-line activities. Instant web messaging system for voice and video chat is one of network applications that allow audio-video bidirectional communication, which is real-time and free over Internet. 
     However, currently instant messaging is mainly used in live web-chat by those who have a certain level of computer and network knowledge. It is executed on sophisticated personal computers. These computers usually have a multi-purpose central processing unit (CPU) chip or chipset in hard drive, and many kinds of software loaded for other irrelevant applications. They have various input/output (I/O) devices, such as a mouse, keyboard, printer, fixed or removable data storage units, and associated media, or a large display screen. It has to use desktop or laptop computers, which are often expensive, bulky and inconvenient for the sole purpose of audio-video communication through Internet. A first time user may need to purchase and attach other accessories, such as a webcam, a microphone or a speaker. The user will also need to download software provided by a messenger carrier to establish network communication. The process to acquire and install above hardware and software are often time consuming and not success guaranteed, and require a certain level of the user&#39;s computer &amp; network knowledge. Many potential customers who are attracted by this feature might be scared away for concerning the required installation process. 
     Accordingly, there exists a need in the network communication industry for an inexpensive and integrated apparatus and method, which overcomes the above-mentioned deficiencies. The apparatus of my invention provides a machine that assembles in one unit all hardware parts necessary for audio-video communication by using instant web messaging over Internet or local network. The invention also embeds inside microchips all software needed for audio-video communication over Internet. The invented apparatus may be a turnkey unit for those customers, who want to make free domestic or international video phone calls over internet but don&#39;t know how or don&#39;t want to go through detailed hardware and software installation.

     Advantages  
     Others have invented elements of hardware and software for instant web messenger over Internet, but mine is superior because it may have one or more of the following advantages:
     1 it is easy and ready to use as a videophone over the Internet.   2 it doesn&#39;t require the user to install more parts or accessories for the said application.   3 it doesn&#39;t need to load software for machine operation or A/V (Audio/Video) communication.   4 it doesn&#39;t need to use a personal computer to establish network communication.   5 it reduces need on computer literacy of a user to operate the apparatus.   6 it is not vulnerable to hackers or virus during A/V communication over Internet as all programs are run using embedded software.   7 it is small in dimension and can be folded when not in use, alloying it to be movable and portable.   8 it allows free A/V communication when access to the Internet is available.   9 it allows more versatile image taking, not limited to the sender itself.   10 it may be used for live video web-chat, domestic &amp; international videophone calls, cooperate video conferences, customer service, technical support/repairing, remote monitoring/diagnose, online ordering, online ads, and security surveillance.

     DESCRIPTIONS 
     The components of my invention are:
         a rotatable and foldable frame in thickness about 1 inch, made of base plate  10  and liquid crystal display (LCD) plate  11  in dimension between 5 to 10 inch.   microchip or micro-chipsets inside base plate  10 , having all embedded software necessary for operation of said application.   keypads on base plate  10  for entering/storing network ID to be called, selecting messenger carrier and controlling operation.   audio/video devices integrated to base plate  10  or display plate  11 : webcam  12  and its rotatable rod  13 , speaker  14 , and microphone  15 .   jacks for DC power in, microphone, headphone, and DSL and cable modem in.       

     In my invention, all hardware components are integrated and assembled into one foldable unit which has all software embedded for network communication and audio/video signal processing. The unit may be ready for use when connected to Internet through cable modem, a router or DSL phone line modem. A user needs to turn on power and sign-in to desired messaging carrier in keypad  18 , to enter first portion of receiving network address (e.g., xxxxx if the address is xxxxx@yahoo.com) through numerical keypad  16 , to select instant messaging carrier on functional keypad  17 , and to initiate dialing by pressing the Call button in keypad  18 . The party to be called will be alerted the incoming call. Two-way audio/video communication via network will be established if the receiver answer the call. 
     An instant messaging carrier is defined here as a network service provider who has its own server and supporting software for voice and video communication. Instant messaging carriers available in my invention may be some, all or more than the examples given below: Yahoo, MSN, AOL, Skype, Paltalk, SightSpeed. 
     When it is powered on and connected to network, the unit of my invention may ring to alert an incoming call. A user may decide to start the audio/video communication by pressing the Answer button in keypad  18 . The network address to be called may be stored, listed, withdrawn, deleted or modified in keypad  17 . By pressing Image Switch button in keypad  18 , a user may view images of both sender/receiver, receiver only or sender only, as shown in  FIG. 3A-C . The webcam  12  can also be pulled up from webcam adjustable rod  13  mounted on LCD plate  11  and rotated 180 degree backwards, to display surrounding scenery of the sender. 
     SUMMARY 
     My apparatus has one or more of the following benefits:
     1. simplicity, low cost and ease of operation, because all hardware parts are integrated and assembled into one unit in my invention and the apparatus uses those hardware and software components that are necessary only for web voice/video messaging application.   2 less interference from virus or network hacker and no need to download extra software, because all necessary programs are embedded in microchips.   3 usage as a video phone over internet or local network.
