Generation of a transport stream for DVB and realisation of a HF-modulated DVB-signal

The pattern generator was firstly connected to an oscilloscope to check the integrity of the
produced signals. Later on there was a colour TV connected parallel to the oscilloscope so that
the check could be completed -Almost at the end of the thesis progress, some new Samsung
TVs were received for the laboratory, so the signals were tested there too. These new TVs were
digital smart LED TVs. The signal was of better quality and more stable. The overall quality was
better because of the characteristics and the settings of the digital TV.
After a thorough check to all the features of the pattern generator, it was ready for use.

The oscilloscope was disconnected and replaced by Roxio video capture USB, the device that
would lead the signal to the computer and do the conversion from analog to digital.
