"This set of equipment with many functions is also very expensive, such as switching back and forth between programs and advertisements in the future, and even the process of playing programs 24 hours a day, can be intelligent many times, and the power of digitalization Sure enough, it's extraordinary."

Looking at the various functions demonstrated by the DVO-1 system, Ted Turner exclaimed: "You are forcing the entire radio and television industry to enter an arms race. I have to hurry up and get armed. The opening of the Friendship Games is only a few months away."

Old God Tang Huan smiled on the ground, "Then you have to quickly arrange for the training of personnel. No matter how advanced my tools are, you also need your operators to be hard enough."

Ted Turner nodded slightly, and turned the front of the conversation: "You can't always look at the results of your high-tech advancement into the traditional radio and television field. You promised me, the technology that allows cable TV networks and high-tech to marry is It's time to show up."

"I know you are impatient." Tang Huan laughed, then made a gesture, motioning him and himself to visit the office on the upper floor.

Ted Turner's "technology of the marriage of cable TV networks and high-tech" is naturally a technology that uses two-way coaxial cable to provide Internet-related application services, which is the well-known CableModem in time and space. .

Its basic principle is to set an uplink frequency for the Internet to upload data, while the Internet downloading data occupies one or more TV channel bandwidth.

The practice of using cable television networks to provide computer network functions emerged in the late 1970s. Government agencies such as the Lynton Johnson Space Center in Houston and the Walter Reed Army Medical Center in Washington deployed test networks respectively, and the speed reached 307.2kbps.

Compared with the general speed of 300bps in the traditional public telephone network dial-up Internet access at that time, this indicator can only be looked up. Even if Pacific Telecom, which is now in the front of the Internet, can provide network access speeds of only 1200bps, 2400bps, 4800bps It's only one grade, and there is a gap of hundreds of times between the two.

However, there is still a long way to go before the experimental network really enters the field of commercial applications. The influence of this practical result is far inferior to the predecessor of the Internet.

In 1985, that is, last year, the IEEE802 committee of the Institute of Electrical and Electronics Engineers defined a standard-10BROAD36, which was used to regulate the establishment of a 10M Ethernet on the coaxial cable of the cable television network.

Tang Huan naturally has his own pace of technological advancement, and there is no need to follow these institutions to explore across the river by feeling the stones.

The reason why the current Internet has no way to increase the speed is that the underlying structure is many times more complex than a local area network such as Ethernet; while traditional public telephone networks and cable television networks use their own network resources to provide Internet services, which has further increased The complexity involved.

Fundamentally speaking, the perspective is taken to the extreme micro-physical circuit and the signal flow transmitted on it. They are undergoing various encoding and decoding conversions at all times. This is also the ultimate meaning of IT technology. Whether it is mechanical, electromechanical, electronic, or optoelectronic or quantum computers that are still in the stage of science fiction, they are just different tools. They have evolved to provide faster efficiency and convert such mathematical encoding and decoding. .

These encodings and decodings are software achievements and can be derived as long as the intellectual resources are sufficient; but the conversion of these encoding and decoding computing devices will be subject to the objective level of hardware development.

Similar to Tang Huan’s research center, the flash memory product has been launched, but at this stage it can only be used simply for storage of firmware programs such as boards. It is also very difficult to build a solid state drive at any cost, because it is not available. Main controller with sufficient computing power.

The same is true of the Internet now. The encoding and decoding of various schemes and the computing power of the signal processor are mutually restricted, and researchers cannot find an optimal solution.

Tang Huan was different. He was born with a global view. From the successful Data-Over-wired cable data service interface specification, DOCSIS, which was successful decades later in time and space, he knew how to find a solution now.

In the era when DOCSIS was popular, the cable television network basically developed to the Hybridfiber-coaxial-Hybrid fiber-coaxial network or HFC stage.

It consists of three parts: optical fiber trunk line, coaxial cable branch line and user distribution network: the program signal from the cable TV station first becomes an optical signal for transmission on the trunk line; after reaching the user area, the optical signal is converted into an electrical signal. After being distributed by the distributor, it is sent to the user through the coaxial cable.

Now, although the application of optical fiber technology has begun to receive great attention, the cable television network is still in the stage of-CATV, that is, the trunk line is also served by coaxial cable. First of all, there is no need for the electrical-optical connection from the TV station to the optical fiber trunk line on HFC The signal conversion, and the optical-electric signal conversion after entering the user area, is much more difficult.

Under such layer-by-layer decomposition, we discard QualityofService——Quality of Service is QoS, VoiceoverIP——Internet Protocol call technology, namely VoIP, data encryption and decryption, network security, etc., which are temporarily not used or can be considered later. Tang Huan finally got a set of CableModem-cable modem Internet service technology solutions that belonged to him and met the current objective conditions.

The reason why Tang Huan was willing to spend more than one billion US dollars to help Ted Turner acquire Metropolitan Media’s cable TV network, in addition to wanting his power to enter the media field, Hollywood’s entertainment industry and the marriage of the media industry, he also rushed. Cable TV networks have the ability to provide Internet access.

You know, in the original time and space, CableModem is forcing telecom companies to vigorously promote ADSL technology to compete and become a major Internet access service method. This shows how great its potential is.
