32/48QAM Low-density IPQAM Modulator

上市日期: 2019-06-03

The low-density IPQAM modulator is a new generation of headend modulator which adopts the international leading technology and is a universal platform for digital TV with high reliability, flexibility and customization.

The low-density IPQAM modulator receives the multimedia transport stream from the video server or CDN network through the Gigabit IP (GbE) network interface, extracts the specified TS program stream from it, and performs related processing such as multiplexing, buffer debounce and up-conversion etc. , and output the signal from the RF port to the HFC network after QAM modulation. It is widely used in value-added services such as digital TV broadcasting and interactive on-demand. A single machine can support QAM signal output of 48 frequency points at the same time, and can be flexibly placed in the main front-end, sub-front-end or residential fiber aggregation point.
