Outline
NEP100-A2 is a Multi-Channel Audio Transcoder. It can receive the IP streams over UDP/RTMP/RTSP/HTTP/HLS/SRT protocol, have multi-format files uploaded, convert the source audio formats and output IP streams over UDP/RTMP/HTTP/HLS/SRT protocol. It is an ideal choice of audio transcoding application in TV programs.
Key Features
* Audio transcoding of max 40 TV programs (not audio program) under the specific condition
* Audio format conversion among MPEG 1 Layer 2, AC3, LC-***, HE-***, HE-*** -V2, video bypass
* 4 GE bidirectional Ethernet ports, input or output settable
* Video files uploading in TS/MP4/MKV/MOV/FLV format
* IP input over UDP/RTMP/RTSP/HTTP/HLS/SRT
* IP SPTS output over UDP/RTMP/HTTP/HLS/SRT
* Web-base GUI and LCD/Key button for easy management

Notification:
Program number differs from the different parameters and different test conditions.
CPU utilization is suggested to be lower than 80%.
If a TV program has more than one audio, all audios will be transcoded under the same setting, such as audio format and audio bitrate.
Purely audio program is not available for this transcoder.
