Product Overview
3526SA is a high performance and cost-effective encoder modulator designed by Dexin. It has 16 CVBS input with MPEG4 AVC/H.264 Video encoding and 1 DVB-C tuner input and 8 non-adjacent carriers output with multiplexing, scrambling (DVB-C only) and DVB-C/T modulating included. It supports maximum 256 IP input and IP (8MPTS) output through Data port. DX3526SA is also characterized with high integrated level, high performance and low cost. This is very adaptable to newly generation CATV broadcasting system.
