This set of equipment with many functions is worth the money. For example, switching back and forth between programs and advertisements in the future, and even the process of broadcasting programs 24 hours a day, can also be many times more intelligent. The power of digitalization It really is extraordinary.”

Looking at the various functions demonstrated by the DVO-1 system, Ted Turner sighed in admiration: You are forcing the entire radio and television industry to engage in an arms race. The opening of the Goodwill Games is just a few months away.

The old god Tang Huan smiled on the ground, Then you have to arrange for manpower to receive training quickly. No matter how advanced my tools are, I still need your operators to be of good quality.

Ted Turner nodded slightly, then changed the topic and said: You can't always look at the results of your high-tech continuous marching into the traditional broadcasting and television fields. You promised me that the technology of marrying cable TV networks and high-tech is It's time to show up.

I knew you were impatient. Tang Huan laughed, and then made a gesture, signaling the other party and himself to visit the office on the upper floor.

Ted Turner's cable TV network and high-tech marriage technology is naturally the technology of using cable TV two-way coaxial cable to provide Internet-related application services, that is, the well-known CableModem in the original time and space—cable modem .

Its basic principle is to designate an uplink frequency for Internet upload data, while Internet download data takes up one or more TV channel bandwidths.

The practice of using cable TV networks to provide computer network functions appeared in the late 1970s. Government agencies such as the Lyndon Johnson Space Center in Houston and the Walter Reed Army Medical Center in Washington deployed experimental networks with speeds reaching Got 307.2kbps.

Compared with the common dial-up speed of 300bps in the traditional public telephone network at that time, this indicator can only be looked up to. Even Pacific Telecom, which is ahead in the Internet field, can only provide network access speeds of 1200bps, 2400bps, and 4800bps. There is only a grade, and there is a gap of hundreds of times between the two.

It's just that there is still a long way to go before the experimental network can truly enter the field of commercial applications. The influence of this practical result is far less than that of 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 over 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 by feeling the stones across the river.

The reason why the current Internet has no way to speed up is that the underlying architecture 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, further increasing the complexity of it.

Fundamentally speaking, putting the perspective into the extreme microcosm—the physical lines and the signal flow transmitted on them, they are undergoing various encoding and decoding conversions every moment, which is also the ultimate meaning of IT technology. Whether it is mechanical, electromechanical, electronic, or photoelectric and quantum computers that are still in the stage of science fiction, it is just that the tools are different. Their evolution is only 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 computing devices that convert these encodings and decodings are subject to the objective level of hardware development.

The research center under Tang Huan has launched a flash memory product, but at this stage it can only be used simply for storing solidified programs such as boards and cards. A main controller with sufficient computing power.

The same is true of the Internet now. The coding and decoding capabilities of various solutions 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 holistic view. He knew how to find a solution now from the successful Data-Over--DOCSIS standard after decades of time and space.

In the era when DOCSIS was popular, the cable TV network basically developed to the stage of Hybridfiber-coaxial—HFC network.

It consists of three parts: the optical fiber trunk line, the coaxial cable branch line and the user distribution network: the program signal from the cable television station is first transformed into an optical signal and transmitted 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 TV network is still in the stage of CATV, that is, the trunk line is also served by coaxial cables. The difficulty of signal conversion, as well as optical-electrical signal conversion after entering the user area, has been greatly reduced.

After such a layer-by-layer decomposition, throwing away QualityofService-quality of service is QoS, VoiceoverIP-Internet protocol communication technology is VoIP, data encryption and decryption, network security and other features that are temporarily unused or can be considered later, Tang Huan finally got his own set of CableModem—a cable modem Internet service technology solution that meets the current objective conditions.

The reason why Tang Huan is willing to spend more than one billion dollars to help Ted Turner acquire Metropolitan Media's cable TV network is not only to let his power enter the media field, but also to marry Hollywood's entertainment industry and the media industry. Cable television networks are capable of providing Internet access.

You know, in the original time and space, after another ten years or so, CableModem forced telecom companies to vigorously promote ADSL technology to compete and become a major Internet access service method. This shows how much potential it has.
