NDS3526SA 16 CVBS MPEG4 encoder modulator DVB-C DVB-T mpeg4 dvb-t modulator
Product Description
Product Overview
NDS3526SA is a high performance and cost-effective encoder modulator designed by Dexin. It supports 16 CVBS input with MPEG4 AVC/H.264 Video encoding and 4ch DVB-C/T non-adjacent carrier outputs with multiplexing (and scrambling in DVB-C out version) included. It also supports up to 128 IP input for re-mux and IP (4MPTS) output through Data port as mirror of carriers. NDS3526SA is also characterized with high integrated level, high performance and low cost. This is very adaptable to newly generation CATV broadcasting system.
