What else can I help you with?
Can television satellites which broadcast information as electromagnetic radiation send signals from the vacuum of space?
i should imagine its because EM waves can travel through a vacuum so that's why it is possible for satellites to broadcast information from impulse signals sent from outer space
What makes an object a satellite in outer space?
An object that orbits the earth. for example the moon or the ISS or the telecommunication satellites that broadcast TV
Name a job which an artificial satellite might have?
Satellites have a variety of different jobs some broadcast television while others are used in GPS systems.
Why does tv use radio waves?
because on the em spectrum, radio waves are the lowest. if a tv used a higher raadioactive source like uv and you were exposed to it to much (by watching to much tv) you could get cancer and die unfortunately.
What is the difference between terrestrial TV and satellite TV?
Terrestrial is earthbound. It is broadcast from antenna towers here on Earth. Satellite TV is broadcast by communications satellites from outer space in geosynchronous orbit. They orbit at the same rate that the Earth rotates, therefore they remain "parked" over the same geographic region, relative to the surface of the Earth they are standing still. Terrestrial TV also makes use of satellites, but rather than broadcasting directly to a customers dish, they are broadcasting specifically for re-broadcast by local network affiliates over their terrestrial antennas.
What are tv waves used for?
Electromagnetic waves in the assigned frequency range of each channel are used to carry information to the TV receiver, which the receiver can use to reconstruct copies of the sound and picture that go together to make up the program being broadcast on that channel.
What is the difference between telecast and broadcast?
broadcasting is the process of sending information (ex:video signals or tv programs) to distant places is called broadcasting but where as telecasting refers to broadcast (ex:tv programs) the programs on television i.e. the broadcasted information.
How is closed circuit television different from broadcast television?
A circuit television is also known as a CCTV or a surveillance camera. A CCTV is a video camera, which only send signals to particular vicinity, on a limited batch of monitors. Whereas a broadcast television, can transmit and admit radio waves, which does not require any satellites to receive signals.
Who made the first satellite tv?
Direct Broadcast Satellites or DBS was the first to have established regulations by year 1980. However, satellite-delivered signals have transformed the television industry since the late 1970s.
Did tv stations air their brodcasts from space?
No, TV stations do not broadcast their programs directly from space. Satellite communication technology is used to transmit signals from Earth to satellites in space, which then retransmit the signals to users on the ground.
How can a TV broadcast be sent to the entire US?
A TV broadcast can be sent to the entire U.S. using a combination of terrestrial broadcasting and satellite transmission. Television signals are typically transmitted from broadcast towers across the country, which cover specific geographic areas. For nationwide reach, networks often use satellites to relay their signals, allowing cable and satellite providers to distribute the broadcast to millions of households simultaneously. Additionally, streaming services and the internet can further enhance accessibility across various devices.
How is the live telecast of Commonwealth Games done globally via the satellites and since when was this made possible?
The broadcast center is the central hub of the system. At the broadcast center or the Playout & Uplink location, the television provider receives signals from various programming sources, compresses these signals using digital compression (scrambling if necessary), and beams a broadcast signal to the proper satellite. The satellite receives the signal from the broadcast station and rebroadcast them to the ground. The viewer's dish picks up the signal from the satellite (or multiple satellites in the same part of the sky) and passes it on to the receiver in the viewer's house. The receiver processes the signal and passes it on to a standard television. This was found in the year 1974.
