The digital image transmission simulation by the model of the digital transmission channel
International Symposium on VIPromCom Video/Image Processing and Multimedia Communications - Trang 401-406
Tóm tắt
The contribution deals with the simulation of non-compressed digital image transmission by a model of the digital transmission channel in baseband. The transmitted digital image corresponds to the CCIR ITU R-601 recommendation that is set up as a standard in digital video broadcasting baseband image processing. The channel is modelled as a digital filter with variable parameters and type of the channel. The whole simulation is aimed at the research and education area of the digital television signal transmission in baseband and quantification and evaluation of the distortions that may have influence on the transmitted digital signal in the digital television technique according to the standard DVB in the spatial, time and frequency domain.
