Also a UA-cam or a Netflix video is an on demand video, meaning each user can start watching at any time. So that is exclusive session created per user. So it becomes a multicast. Where's a TV stream is a broadcast where everyone is viewing the same frame.
sir your efforts are admirable. . really very informative video. I have watched all videos of this channel. thank you so much for increasing our knowledge. keep continue sir .best wishes
Excellent video. Still, I would like to make a small correction: the main reason that allows using a smaller dish antenna is the use of a higher operating frequency and not exactly the power involved in the transmission. The higher the operating frequency, the shorter the wavelength. Therefore, a smaller antenna can be used while maintaining directivity.
You have forgotten another more important detail, how far away should the supposed "satellite" be, how much transmission power is needed and the maximum bandwidth? I don't think a satellite is in the middle of this triangle, instead I think a lot of terrestrial repeaters are used, and terrestrial TV dishes pick up signals that are bounced back into the atmosphere. With the amount of television channels that there are in the world, I have never heard of a satellite failing or a satellite being repaired, or a television satellite going down.
I am trying to understand if DirecTV or equivalent has one satellite orbiting the earth, how are so many dishes across the country able to pickup that signal? Can the same satellite signal / radio wave signal be distributed over such a wide geographic area, or how does that work? If there is one satellite that is staying at a fixed position, and dishes in Los Angeles and New York are pointed towards it, is that satellite able to beam the same signal to both dishes? Thanks!
Great theory... how they have solar panels that last longer than any other and batteries that never need replacing and fuel for the thruster that never runs out is amazing.
Commercial satellites generally last between 5-15 years and have enough fuel on board to last that long. They're also equipped with solar panels of high efficiency, usually around 30-34% compared to the 15-20% efficiency most ground solar panels absorb. So they do run out fuel. When they do, it can no longer be kept aligned to Earth and eventually fall out of orbit and gets burned up.
An excellent video, but i must say it needs a minor (but important) correction. There is no centrifugal force, just centripetal force and it is the equivalent resultant of the system. The gravitational force is a force that is part of this system and contributes (eventually along with other forces) to achieve the resultant of the system (the centripetal force). That`s an application of Newton`s Second Law.
@@shaungranger2166 electrical huh, that’s bs, anyone that believes that is insane and needs a tin foil hat…these would burn up from extreme temperatures
@@snakeNP215 because the primary, source of power is solar power that's why logically I thought electrical power, but I think they do get serviced once in a while refueling etc
How geostationary satellites orient themselves (some form of GPS, ground reference signal) to make sure they remain in the same position relatively to their ground reference point?
Correct, the reason why I move to IPTV because it's now more reliable than satellite TV. Perhaps, the previous satellite TV company keep losing demand and now bankrupt ☠️
@rent a shill , not what i said idiot. Said they was fed by submarine cables idiot. Big difference. But you being a useless democrat has just got to change the words to suit your idiocy.
I dont agree with your explanation about the difference between internet videos vs television. The internet videos buffer because there will a status check for each packet receiving and if it's not recieved then it is retransmitted by the source. This what enables us to forward or rewind videos on internet streaming. Coming to telivision its not the same the packets sent are not verified and this is the reason if there's a connection interruption the video doesnt resume from it stopped it start from the point from the recent packet which is the reason we miss some potion of the video and this why it doesnt get buffered.
Hmmm... I don't know about this. As someone who lives down in South Africa I have never seen a single satellite dish pointed out south towards Antarctica, for instance. Instead they all seem to be pointing out to ground based antennas located on mountains on other high places. This explanation on the video seems fishy
Wait, so the signals are broadcast in a line, i thought EM waves travel outwards like a sphere of wave, wouldn't you need tons of satellites to broadcast a single signal to each antenna.
The video is slightly misleading. In reality the satellite emits waves as a cone that "lits" a specific region of the earth, pretty much like a very directional lamp would do on a table. At earth surface, the waves can be approximated as a plane moving torwards the ground (given the huge distance) so the receiving dishes have to be aligned perpendicular to that plane
Do all satalite orbit around the equator? Or do they change angles they rotate at? Like would a satalite broadcasting to Brazil be rotating relatize to brazil, and same thing for iceland, or would they both be orbiting at the equator?
A delay on satellite can be delayed between 5 to 15 secounds in Europe. It is also how the signal is transmitted. Example CNN International is delayed 25 secounds at 1 degree west. And on Astra 28 degree east it is delayed about 18 secounds.
1080 HD still is terrible with dish and DirecTV. Heck in another 5 or 10 years both services might end up disappearing anyway because the fact that fiber internet through isps can now deliver internet phone and TV with 4K compatibilities makes for a great experience plus when you get a little cloud in the sky your TV doesn't go out like it does when it storms heck you could get a little light rain with the two satellite companies and it go out on you plus it's just a lot of reruns so why spend $80 to $100 or more a month when most of us are going to be working most of that day and you're only going to get a couple hours anyway thanks first people LOL
Sattelite Tv never use tower like cell phone tower. Only Terrestrial Tv service use Tower or broadcast antenna on ground. DVB T2 is latest technology for terrestrial Tv broadcast
Towers in the Pacific and the Sahara - really? Why do the directional dish antennas have to be pointed upwards at a specific spot in the sky? Why don't you go out on a dark night and look a the low-orbit satellites passing over your head!
HELLO THANKS FOR MANY PHYSICS EDUCATIONAL VIDEOS WHICH YOU PROVIDE US. MY REQUEST IS CAN YOU PROVIDE A VIDEO ABOUT A MAGNETIC LEVITATION TRAIN (MAGLEV TRAIN)
I want to know if satellites are using microwave(a high frequency wave) to transmit signals then why not the antenna melts or if we put our hand on the antenna it hurts??.. Any knowledgeable being answers me(a science student)
Hi learn engineering team the video is awesome But how the viewing card in dth , role does it connect with satellite or mobile tower to get recharge details and subscriptions
recharge details are sent by satellite,the sent signal contains all subscribers and there package details..aur set top box just needed to catch its own set top box details from the signal(which contains all users data)thats why it takes some time to start the channel after we racharge(unlike mobile recharges,which comes within a second)

It's magic of maths
they all have atomic clocks that are synced with ones on earth to solve for position in all axes. it's impossible to explain in a youtube comment.
This is somewhat wrong. The way it works is through She farms, and radio antennas. I work for FiOS. No satellite is used.

How are TRPs calculated ?
The satelite has a higher speed than the Earth's surface, it has to cover a much greater distance for one revolution.
different satellites have different speeds.
They are talking about angular velocity. That should be same.
