Hangzhou DIBSYS Technologies Co.,Ltd
DVB6400 is a significant performance models, high-quality low-cost broadcast DVB-T / H terrestrial digital TV modulator. It is consistent with medium and small-scale systems integrators, operators and building the necessary terrestrial digital television solutions and DVB-T / H set-top box testing requirements. In particular, for the broadcast of high quality requirements, the product especially in the single frequency network synchronization, digital pre-distortion algorithm to improve the optimization.
