Product Overview
XLD3544K Multi-Channel Encoder is the new broadcasting audio & video encoding and multiplexing device with powerful functionality. It is equipped with 12 HDMI audio & video input interfaces, 12 CC input ports (Closed Caption) and 32 IP input over UDP and RTP through Data1.
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 (Optional), and AC3 (2.0/5.1) pass through. 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.
