Product Overview
VEK-4782L Multi-Channel encoder is a professional HD audio & video encoding and multiplexing device. It has 4/8/12/16/20/24 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 4/8/12/16/20/24 channels HD audio & video; moreover, the IP output can support 1MPTS and 4/8/12/16/20/24 SPTS, IP output from Data1 or Data2, and support 1 MPTS or 4/8/12/16/20/24 SPTS (16/20/24 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.
