    Simulation of DigiCipher, an HDTV system proposal
    (1991) Öktem, Levent
    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.
