Abstract
In this thesis, the digital video encoder-decoder parts of an American
HDTV system proposal, DigiCipher^^'^ is simulated in an image sequencer,
based on the system description sheets. Numerical and subjective performances
are tested, by observing and making calculations on the decoder outputs of the
system simulation. The performance tests show that the image quality does not
have HDTV quality. Considering the very good picture quality in the demonstrations
of the designer company (General Instruments), it is suspected that
the description sheets do not mention all of the data compression methods used
in the system.
