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
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.
3:00 I have a little experience working in the field, and a way to compensate for Ku rain fade/attenuation is through the installation of an Uplink Power Control. Basically, the device constantly measures the satellite beacon level (receive path). They do this because when it rains, the beacon level drops so thus, the signal drops as well. When the beacon level drops too low, the UPC removes attenuation from the Ku transmit path, resulting in the amplifiers transmitting the signal with more power to get through the rain. Compensation. Many newer satellites have ALC, or automatic level control, where the satellite compensates, so a UPC isn’t necessary. It’s pretty interesting stuff.
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.
Thank you for making this informative video. Please make video explaining the details regarding satellite tv considering following as major questions - 1. How does satellite recognise the customer's dish in spite of one way communication? 2. How access to only certain channels is given to the customer based on subscription? 3. When we stop paying the subscription, access to channel gets disconnected. When we pay, it starts again. How does this work? Please reply till the video gets made.
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.
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?
Wonderfully instructive video. Especially I didn’t know how internet TV was different from regular TV broadcasts . Many thanks for the enlightening video.
@@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
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
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 ☠️
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

Today's generation students are very lucky...they are using the Internet with clear examples but in the past we just imagined the topics
satellite tv is falling out of mainstream
But luckily we have this channel!!
No, they didn't have so Complex machanism as we have now. We obviously diserve better than them.
Ok boomer
Nah were not that lucky cause phones are now stressing and stop making me from doing my homeworks
Am I the only one impressed with the fact he used a curved TV and warded the image to fit it? A normal screen would have been a lot easier
Some good software.
6:08 I was wondering the same thing
😂 Did you see actual cnn presenters
Yeah bro it's not a that much difficult process. If you are familiar uv unwrapping process.
It's easy to do in any 3d app. 3 steps for me in autodesk 3ds max 😎

Multicast!??? Netflix movies are just saved in a server.
@@topgunnc12 what about live iptv?
@@topgunnc12 I want to start my own sports iptv service in the next 3-4 years.
How one can argue that it's not the best UA-cam channel.
No one can do this

Not only the people who design satellites are genius but you are also amazing.. impressed by concept, content and representation
Thankyou ❤️

really very informative video.
I have watched all videos of this channel. thank you so much for increasing our knowledge.

Awesome video as always.
I am so grateful that you give me the chance to teach my little brothers some useful stuff through ur videos.
Thanks a lot.

I really admire how humans got to know about all these..!
Its just like a imagination 🤯
Man this channel is something this is so good!

Sir,
am really impressed by your tutorials. I hope ur channel management will do well to provide us more satellite tutorials
Hhhh u still believe in existence of satellite!!it just about frequency that travel on athir !!
It’s so cool knowing how these things work !!! Makes me appreciate them even more .
Salute to you man,Wooowww!
What a great way to explain this complicated concept👌👌🤙
One of the best satellite videos i have come across. Good explanation
Really impressed with the animations and the way how is explaining the topic
This is the best explanation of TV broadcasting ever heard in my life I’m interested in TV broadcasting
A good explanation thanks.
I learn ALOT from this channel! Thank you!!

Perhaps he means that the energy is inversely proportional to the wavelength according to the relation E=hf...

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?
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.
Jhakaas vdo sir ji😇😇💚💙
Make a topic about atomic clock
This video has helped me a lot 👍😊
1:30 "Crowded". Bro it's on a circle of circumference =π(42,164,000)² m ffs.

How do they maintain battery without fail? What if battery fail?
The solar panels recharge the battery when facing the sun.
But how do they maintain the battrey? Wat if battry dead?
I love this chanel , I am delighted !! Again TY !!!!!!!
TV.
Flat earthers belike: no it's fake. It's magic
Yes its Magic. Because satalite television is older than the first satalite in the air. But how, its a kind of Magic .

Oh are a kannadiga
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.
Am late but am now here.have subscribed.nice tutioral

Why you delete this video yesterday
ITS SO HELPFUL

There is no satellites, because Earth is flat.
