Abstract :
The paper deals with the component analysis of DVB (digital video broadcasting) transmission model in baseband and its source, channel and link coding. The transmission channel model is based on the digital filter design and it can be designed with the variable transmission parameters (e.g. cut-off frequency) and linear distortions with additive noise and reflected signal. Results of achieved BER (bit error rate) and SER (symbol error rate) and corresponding PQE (picture quality evaluation) analysis are presented, including the evaluation of subjective picture quality influence on normalized cut-off frequency of the channel
