Hello Kushagra, I can't. I've never looked into the details of digital video signals and so I would be starting where you are. As I said, I would start by trying to run the existing code and getting it working. From there you can research online for information about the video signals inside your test setup then start comparing that with the signals received by the working application. When you get to that point and have questions we may be able to better help you with specific questions.
I hope you do choose this or another project involving GNU Radio for your final year presentation. We'd be very interested in hearing how the project goes.
