Product Overview

多路解调适配器

GQ-3655 is the GOSPELL’s latest multi-functional IPQAM product series, which can receive multiple program sources from cable (or satellite, DTT network), IP network and local ASI, and then re-multiplexing, scrambling and modulating it with channel coding.

GQ-3655 adopts GOSPELL’s flexible licensing mechanism for scrambling function and numbers of QAM channels. This flexibility can provide a lower capital expenditure (CAPEX) in initial phase and better asset protection in network expansion stage to DTV operators. Due to its flexibility and versatility, GQ-3655 can be widely applied to DTV head-end system, in different areas, depending on operators requirements, such as cable DTV head-end, sub head-end, or broadcasting center.
