The traditional cable television broadcasting, digital mobile television broadcasting and the direct satellite video broadcasting ensure the television services of people’s daily life. Owing to digital broadcast satellite, also known as the digital video broadcasting (DVB) protocol applying terminal, direct-to-home television services with an outdoor dish of one meter come true. In order to accommodate the requirements of various broadcasting services, the DVB-S.2 protocol provides more efficient technology details. The LDPC codes concatenated with BCH codes achieve high performance near the Shannon limit and have low encoding and decoding complexity. Some high efficiency modulation methods are introduced into theDVB-S.2, such as QPSK, 8PSK, 16APSK and 32APSK. The adaptive coding and modulation (ACM) according the channel performance (E s /N 0 ) is applied in the DVB-S.2 technology. In order to preventing the burst disturbance, satellite broadcasting via variable frequency band is presented in this paper to ensure the quality of services. The DVB-S.2 via variable frequency is simulated based on Matlab/Simulink in this paper, and the simulation implements the video streams coding and modulation, ACM and frequency change with the channel performance.
