A TV is able to show what is happening in any other area through the process of broadcasting. Broadcasting involves capturing audio and video signals from a specific location, encoding them into a format that can be transmitted over the airwaves or through cables, and then transmitting them to a receiving device, such as a TV.
The TV receives these signals through an antenna, cable connection, or internet connection, and decodes them back into audio and video signals that can be displayed on the screen. This allows viewers to watch live events, news broadcasts, movies, and TV shows from anywhere in the world in real-time.
In the case of live events, such as sports games or concerts, cameras and microphones are used to capture the action and sound, which are then transmitted to a broadcasting station. The broadcasting station processes and encodes the signals before transmitting them to TV stations or networks, which then distribute the signals to viewers through their TVs.
Overall, the technology behind broadcasting allows TVs to show what is happening in any other area by capturing, encoding, transmitting, and decoding audio and video signals in real-time.

Television Signal Transmission and Display
Televisions receive a signal that contains image and audio information and convert it into a display on the screen. The process involves multiple stages:
1. Broadcasting:
- A camera captures images and sound from a scene, such as a sports match or news report.
- The camera converts the captured information into an electrical signal.
- The signal is modulated (encoded) and transmitted through a broadcast medium, typically using radio waves.
2. Signal Reception:
- A television antenna receives the broadcast signal.
- The antenna demodulates (decodes) the signal and sends it to the TV.
3. Picture Creation:
- The TV processes the signal using an image processor.
- The image processor divides the signal into individual pixels (picture elements), each representing a specific color and brightness value.
- The pixels are arranged in a grid to form the image on the screen.
4. Refresh Rate:
- The TV refreshes the image on the screen at a certain rate, typically 60 or 120 times per second.
- This refresh rate ensures that the image appears smooth and flicker-free.
5. Color and Brightness Adjustment:
- The TV's backlight provides the overall brightness of the image.
- The TV's color settings determine the intensity and hue of the colors displayed.
- The combination of brightness and color creates the desired visual experience.
6. Sound Reproduction:
- The TV's audio system processes the audio signal from the broadcast.
- The speakers in the TV amplify and reproduce the sound, allowing viewers to hear the audio accompanying the images.
Transmission Infrastructure:
The television signal is transmitted and received through various infrastructure components, including:
- Broadcast transmitters: Send the signal from the camera to the receiver.
- Satellites: Used for broadcasting over long distances and to reach remote areas.
- Cable networks: Distribute the signal through a network of wires to homes.
- Internet streaming services: Deliver the signal over the internet, allowing for on-demand viewing and wider accessibility.
By combining these processes, televisions can display images and sound from remote locations, allowing viewers to watch events, shows, and news from anywhere in the world.
