What is the problem ?
When we try to establish a proper audio-visual communication from the Earth with the astronauts in space, following major issues occur
No internet
Internet is available for goestationary bodies and bodies revolving around the Earth, but inter planatary missions can not have internet connection
Less Bandwidth
All data has to be passed from space using a singal signal. This creates bandwidth problem for audio visual data.

These audios might help you to understand the problem
Our Approach
Here is how we can solve the problem
Collect Audio and video data
As there will be multiple astronauts, we have to collect audio data of all. However, video data will be from a single source
Apply filters and remove noise`
Matlab and python libraries will be used for this task. The same functions then can be used in a framework like django to create an API which further can be used by various devices and platforms
Merge the data in one signal
We have developed a special algorithm using which we can merge the data in one signal
Decrypt that signal again!
The merged signal will be received on Earth, there we need to get all audio and video data back in the original form from the merged signal
F.A.Q
Frequently Asked Questions
-
Why can't we directly use internet?
In space missions which are related to Earth, internet is accessible. But for inter planetary missions, internet is not available.
-
Astronauts send written data from space, then what is the problem with audio and video data?
Each astronaut can simply add his name so that people on Earth can read and understand who sent this message. But the same excersise is tedious in case of audio and video.
-
How will you solve this problem ?
We will try to embody all audio visual data in one signal and create a mechanism to decrypt it on Earth.
-
How it can be used?
Once the audio-visual data is jsonified, it can be used on any app, website or even a software in PC.
