Product Overview
XLD3544KF Multi-Channel Encoder is the new broadcasting audio & video encoding and multiplexing device with powerful functionality. It is equipped with 24 HDMI audio & video input interfaces and 32 IP input through Data 1 port. It supports MPEG-4 AVC/H.264 video encoding and MPEG1 Layer II audio encoding (MPEG-2 AAC, MPEG-4 AAC Optional), AC3 pass through. NDS3544KF supports 1MPTS and 24 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.
