Outline
The professional YDN-2201 HD encoder completely fulfill H.264 standard. It is equipped with digital audio/video input or analog input interface; ASI and IP megabytes nets (TS stream) output interface. Customers may choose satellite receivers, local program sources and multimedia players, as well as HDMI and SDI digital audio/video signals to feed into YDN-2201 for encoding or transcoding of TS from other head-end devices in accordance with actual system needs, and output TS in H.264 format. The output TS from ASI and IP ports, will then be distributed to different application devices and systems.
