Description of Invention (丨) L. Background of the Invention The Internet was the hottest topic in the global information industry last year. Most information experts agree that the Internet will become the enabler of the global information highway. The Internet is currently regarded as a cheap way for developing countries to enter the global information system. However, under the monopoly of communications policies and the opposition of some governments, the Internet is still too expensive or cannot penetrate into certain regions. According to estimates, there are now a total of 3 million computer systems in more than 146 countries around the world that can accept data reading services provided by the Internet every day. The number of Internet users has exceeded 31 million, and their performance has been expanding at an alarming rate. We living in the twentieth century can't avoid the influence of the Internet. For example, education, academic research, shopping, entertainment, tourism, transportation, finance, art, news, communications, etc. can all be achieved through the Internet. Good convenience and practicality. It is a pity that although modern people see Internet pictures in their eyes, listen to Internet messages in their ears, and talk about Internet topics in their mouths. But most people don't have the experience to get a glimpse of the Internet. In order to access the Internet, you must have basic equipment. In addition to applying for an Internet account, you also need hardware devices such as personal computers and modems. In addition, learning the operation of the Internet also requires expert guidance in order to be handy. An important fact is that most people do not spend a budget of 50,000 to 100,000 to buy an Internet computer and related equipment in order to see the fascinating style of the Internet. This is also the formation of a country and its ------------^ ---- ^ ---- ir ------ 0 (please read the note on the back and then write the book) The paper standard is in accordance with the Chinese National Standard (CNS) A4 (210x297) 83.3.1〇, 〇00 Ministry of Economic Affairs Central Standards Bureau Beigong Consumer Cooperative Printed 313727 at ________ B7 5. Description of invention () 2 The more the number of personal computers The main reason for the increasing Internet population. That is, the development of the Internet is bound to be limited by the penetration rate of personal computers. Fortunately, the present invention can break this limitation. Ordinary people do not have to buy a personal computer, as long as they are subscribers of cable TV, they can access all the information services of the Internet by using the telephones and TV sets at home. Cable TV is an emerging high-tech broadband media in Taiwan. According to statistics, over 70% of households in Taiwan have installed cable TV services. In the past, the fourth simplistic technology and management model under the cable television law and cable television technical specifications, in the future, cable television will develop into a two-way interactive broadband service network. Many key broadband interactive network technologies' such as: the head-end video server (V 丨 deQ Server) or the client-side video-on-demand (set-top box) and cable modem (cable Modem) are being actively developed And trial. However, in addition to hardware technology, more people are concerned about the two-way interactive services that can attract cable TV subscribers to pay for it. Up to now, the use of cable TV networks to provide Internet online services (Internet Line Service) is one of the most accurate service items. According to the experiment of the interactive service system of TCI Corporation, the largest cable TV company in the United States, S @ HOME, TC1 provides Internet online services on its latest two-way interactive cable TV network. Subscribers charge US $ 30 to US $ 50, and this data service fee is arguably the most reliable source of money for cable operators. Although TCI is using a good-looking two-way cable TV network, it can provide most subscribers with access to the Internet at the same time. The standard is China General Standard (CNS) A4 (210X297mm). -(Please read the note on the back < 11 ^ first and then fill in this page) Order- -Line · 31B727 V.

Let ’s take the phone button “3” as an example. It consists of 6ST7HZ and 1477Ηζ and is decoded as QiQ2Q3Q4 = 00H represents PGUP in keyboard mode and right mouse button in mouse mode. & Please refer to the fourth figure, which is a flowchart of the internal program of the microcomputer of the signal converter of the present invention. Step (3) of this flowchart will determine the keyboard mode or mouse mode. Start processing at step (6>) and judge the received phone key tone. The LED flashes while waiting for the key tone to indicate normal operation of the system. At step (7), determine the number represented by the phone key tone, and then follow The mode selected in step (3) enters step (9) or steps (10) to (12). After the conversion of a telephone key tone, it returns to the position A of step (13) and continues to receive the next key tone. Usually , Select the keyboard or mouse is set by an external switch, therefore, the main operation of the entire program is in steps (6) to step (13). Please refer to Figure (five), which is the system application architecture diagram of the present invention, In the first figure, the system architecture of the present invention has been explained, but that is for the case where only one Internet host is provided at the head end. When the present invention is actually applied, the cable operator can set up more than one according to local needs Internet host. At present, there are many new cable television networks with a system bandwidth of 750MHz, of which the bandwidth of 550MHz to 750MHz is temporarily reserved and unused. The domestic data telecommunications business is open to cable operators Before the adoption of the decree, the 200MHz bandwidth may be intermittent for a period of time. If the present invention is used in this 200MHz bandwidth, the paper standard will be applicable to the Chinese National Standard (CNS > A4 specification U10X297mm) in the shortest time. ) 83. 3.10,000 ί _!
