DVB-T2 gatewayMultiplexer and Re-multiplexer developed forT2-MI gereration for DVB-T2 digitalTelevision standards. It can encapsulate into a T2-MI stream multi TS stemming from a multiplexer or directly from encoders. DVB-T2 Gateway, can support up to8 ASI or 512IP inputs and Multiplexing toone T2-MI packets over4* ASIand 2*IP out.
Based on the most widely DVB-T2 Gateway,YDS8000 is compliant with the major transmitter manufacturers guaranteeing a safe DVB-T2 broadcasting over SFN networks. It can provide an end-to-end regionalization solution using PLP substitution or PLP aggregation technology.
