Outline.
encoder is a professional HD audio & video encoding and multiplexing device.
It has 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. STHD-8511 can simultaneously encode 8/12/16/20/24 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 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.
