Digital Headend Multiplexer with Dual ASI Support – GAOTek

GAOTek’s digital headend multiplexer is a cutting-edge device designed for digital TV broadcasting, featuring 1 IP input, 2 ASI inputs, and support for 6 tuner inputs (ISDB-T/DVB-C/S/S2/T/ATSC). Its high integration allows multiplexing RF signals from satellite and ASI input MPTS, functioning as six standalone FTA IRDs, making it a cost-effective solution for next-generation CATV broadcasting systems.

Description

Overview

GAOTek digital headend multiplexer is the latest demodulation and multiplexing device for digital TV broadcasting head-end system. Different from a normal multiplexer, this multiplexer has 1 IP input, 2 ASI inputs, supports 6 tuner inputs (ISDB-T/DVB-C/S/S2/T/ATSC optional), two separate ASI output ports and one data port for two separate gigabit IP outputs. In other words, it can multiplex the RF signals from satellite into the output ports via the 6 tuners, also it can multiplex up to 2 channels ASI input MPTS into the output transport stream (MPTS). In other words, one Tuner Input. Multiplexers can work as 6 standalone FTA IRD and two separate ASI output multiplexers. In conclusion, it’s high integration and cost-effective design make this device widely used in the Next Generation of CATV Broadcasting system.
