Product Overview
3544KD Multi-Channel Encoder is the new broadcasting audio & video encoding and multiplexing device with powerful functionality. It is equipped with 12 SDI audio & video input interfaces and 32 IP input through Data 1 port. It supports both MPEG-2 and MPEG-4 AVC/H.264 HD/SD video encoding and MPEG1 Layer II, MPEG2-AAC, MPEG4-AAC, Dolby Digital AC3 (2.0) audio encoding, AC3 (2.0/5.1) pass through. NDS3544KD supports 1MPTS and 12 SPTS IP (DATA1 and DATA2 port) output over UDP, RTP/RTSP. Its high integration and cost-effective design make this device widely used in variety of digital distribution systems such as CATV digital head-end, satellite and terrestrial digital TV, etc.
