By television we understand a system for the remote reception and transmission of sound and images that appear to be moving and, at the same time, the specific apparatus designed to receive and visualize them.
This transmission occurs through various systems and techniques, both public and paid, and today plays a leading role among the mass media. So much so that the massification of this device is considered the beginning of the era of humanity’s telecommunications.
On the other hand, television is the mass medium of communication par excellence, so all the reflections made around the media culture, the role of journalism and the “fourth power”, directly concern it.
The transmission of 10.4 inch tft display module images and sound to television sets was traditionally produced by radio waves, which were received by an antenna located on the roof of the building or on the device itself that interpreted and converted them into images and sound.
These signals could be of various types: NTSC, PAL or SECAM, according to their technical specifications that varied according to the geographical region. They were called “analog signals.”
- Transmission options
The content transmitted by television may be live, that is, it occurs at the moment of its transmission , or delayed, that is, recorded and produced prior to transmission.
In this way the television can be used to report on events taking place elsewhere and simultaneously, or to re-present events of days, months or years ago.
- Aspect ratio
This is the name given to the relationship between the width and length of the image projected on the television, which can normally be of two types:
4: 3, the traditional formula for analog television.
16: 9, the format introduced in the 90s by digital television, much broader and more pleasing to the human eye.
- Transmission modes
Currently, four models of television transmission coexist:
Characteristic of the television stations with open or public signal, it is transmitted through radio waves.
Typical of the pay television stations, which offer the client a wide and international programming in exchange for a monthly rental. It depends on fiber optic cables and coaxial connections to the television.
The images of 12.1 inch lcd display screen are transmitted from a repeater satellite, the electronic signal of which is collected by an antenna installed in the building or even in the home window, and then decoded by a module installed in the apparatus.
Internet television, which replaces the television with new generation computers and receives its information via the web, via WiFi or conventional network cable signals.
Television programming can be classified into the following broadcast genres:
They provide news or current content to the public, such as news , current affairs, entertainment, etc.
They pursue educational or training purposes in their audience, such as documentaries, educational shows, opinion programs, etc.
Emissions aimed at children, such as cartoons or puppets.
Entertainment programs for adults and young people, such as humor shows, satire, variety shows, talent shows or contests.
