Description Features Technical Parameter
WK3542L Multi-Channel encoder is a professional HD audio & video encoding and multiplexing device. It has 8/12/24 HDMI video input interfaces, and supports MPEG-4 AVC/H.264 video encoding and MPEG 1 Layer 2 audio encoding. This device can simultaneously encode 8/12/24 channels HD audio & video; moreover, the IP output can support 1MPTS and 8/12SPTS (8/12 HDMI inputs) IP output from Data1 or Data2, and support 1 MPTS or 24 SPTS (24 HDMI inputs). In conclusion, its high integrated and cost effective design makes the device widely used in varieties of digital distribution systems such as cable TV digital head-end, digital TV broadcasting etc.
