Human perception of motion
1. A television system involves equipment located at the source of production, equipment located in the home of the viewer, and equipment used to convey the television signal from the producer to the viewer. The purpose of all of this equipment is to extend the human senses of vision and hearing beyond their natural limits of physical distance.
2. A television system must be designed, therefore, to embrace the essential capabilities of these senses, particularly the sense of vision. The aspects of vision that must be considered include the ability of the human eye to distinguish the brightness, colours, details, sizes, shapes, and positions of objects. Aspects of hearing include the ability of the ear to distinguish the pitch, loudness, and distribution of sounds.
3. In working to satisfy these capabilities, television systems must strike appropriate compromises between the quality of the desired image and the costs of reproducing it. They must also be designed to override, within reasonable limits, the effects of interference and to minimize visual and audial distortions in the transmission and reproduction processes.

How smartphones work
1. Thinking of a daily task it's likely there's a specialized, pocket-sized device designed to help you accomplish it. You can get a separate, tiny and powerful machine to make phone calls, keep your calendar and address book, entertain you, play your music, give directions, take pictures, check your e-mail, and do countless other things. But how many pockets do you have? Handheld devices become as clunky as a room-sized supercomputer when you have to carry four of them around with you every day.
2. A smartphone is one device that can take care of all of your handheld computing and communication needs in a single, small package. It's not so much a distinct class of products as it is a different set of standards for cell phones to live up to.
3. Unlike many traditional cell phones, smartphones allow individual users to install, configure and run applications of their choosing. A smartphone offers the ability to conform the device to your particular way of doing things. Most standard cell-phone software offers only limited choices for re-configuration, forcing you to adapt to the way it's set up.

Smartphone is a powerful machine that is used for standard cell phones re-configuration.
Cell phones capabilities lessen people to use them like smartphones.
Smartphones allow users to install, configure and run applications of their choice.

Cable television
1. Cable television is a system of providing television to consumers via radio frequency signals transmitted to televisions through optical fibers or coaxial cables as opposed to the over-the-air method used in traditional television broadcasting (via radio waves) in which a television antenna is required.  
2. The abbreviation CATV is often used to mean «Cable TV». It originally stood for Community Antenna Television, from cable television's origins in 1948.  In areas where over-the-air reception was limited by distance from transmitters or mountainous terrain, large «community antennas» were constructed, and cable was run from them to individual homes.
3. It is most commonplace in North America, Europe, Australia and East Asia, though it is present in many other countries, mainly in South America and the Middle East. Cable TV has had little success in Africa, as it is not cost-effective to lay cables in sparsely populated areas. So-called «wireless cable» or microwave-based systems are used instead.
Определите основную идею текста.
The application of cable television system in some countries is very expensive.
Cable television system allows broadcasting in areas limited by distance from transmitters or mountainous terrain.
It is possible now to provide television via radio frequency signals transmitted to televisions through optical fibers.
Due to its means of application cable television is the way of broadcasting predominating mostly in densely populated areas.

Fiber-optic communication
1. In fiber-optic communications information is transmitted by sending light through optical fibers. The light forms an electromagnetic carrier wave that is modulated to carry information. First developed in the 1970s, fiber-optic communication systems have revolutionized the telecommunications industry and have played a major role in the advent of the Information Age.
2. Optical fiber is used by many telecommunications companies to transmit telephone signals, Internet communication, and cable television signals. Due to much lower attenuation and interference, optical fiber has large advantages over existing copper wire in long-distance and high-demand applications. However, infrastructure development within cities was relatively difficult and time-consuming, and fiber-optic systems were complex and expensive to install and operate.
3. Due to these difficulties, fiber-optic communication systems have primarily been installed in long-distance applications, where they can be used to their full transmission capacity, offsetting the increased cost. Since 2000, the prices for fiber-optic communications have dropped considerably.

Due to the difficulties concerning complexity and high price of fiber-optic communication systems, they have only long-distance applications.
Fiber-optic communication systems have revolutionized the telecommunications industry and have played a major role in the advent of the Information Age.
Optical fiber is more advantageous over existing copper wire in long-distance and high-demand applications due to its excellent operating characteristics.
