AVS+ Encoder & Transcoder MPEG2 / H.264 Encoder & Transcoder AVS+ DRA
4-in-1 AVS+/DRA Encoder & Transcoder
Product Introduction:
The 4-in-1 AVS+ encoder & transcoder is a newly developed broadcast-grade device compliant with the national standard GY/T257.1-2012. It is equipped with 4-channel CVBS video and unbalanced audio inputs, or 4-channel SD-SDI interfaces, 4 ASI input ports, and 1 IP input port. The equipment can encode 4 channels of SD audio and video signals. It can also transcode TS streams from 4 ASI inputs and 1 IP input into AVS/AVS+ program streams (supports up to 4 programs). The device features 1 group (2 channels) of identical ASI output ports and IP output (supports SPTS, MPTS). Adopting advanced audio and video encoding algorithms, it achieves a far higher compression ratio than the traditional MPEG-2 standard under the same source video quality. Therefore, it is widely applicable in digital television broadcasting systems (terrestrial, satellite, cable, etc.), IPTV servers, streaming media service systems, and more.
