Solution for DVB-S2 to IP Transcoder

Sep 22, 2017

Application Diagram 



Solution 1

 ◆ ENC3580

6* DVB-S2/C/T tuners input

8*SPTS & 1*MPTS (UDP and RTP/RTSP) output; 2 ASI output


Solution 2

◆ Caster-T323

8 FTA DVB-S2 Tuners input

Transcode up to 20 SD or 10x720P or 5-6 Full HD Channels

UDP, RTSP, RTMP, HTTP, HTTP Live Smooth(HLS), FTP Protocol IP Output


Solution 3

Compared with a device integrated DVB-S2 receiver and transcoder Using DVB-S2/IP gateway (IRD1218/IRD1380) and IP / IP Transcoder (Caster-T328/Matrix-IV two separate devices connected to IP networks, will make the two devices play a more independent advantages. Therefore, it will enhance the performance of the entire transcoder and reduce the costs.


◆ IRD1218


Up to 244 SPTS/14 MPTS over IP out

MPEG-TS over RTP/UDP out


◆ IRD1380

8xTuners Input, options DVB-T2/T/S2/S/C/DTMB/ATSC/ISDB-T

8×DVB-CI Slots, multi-program decryption, BISS-1 and BISS-E decryption 



◆ Caster-T328

Transcode up to 200+ SD Channels

UDP, RTSP, RTMP, HTTP, HTTP Live Smooth(HLS), FTP Protocol IP Output


◆ Matrix-Ⅳ

High density 2-RU platform can transcode up to 120*SD or 60*720p or 24*Full HD profiles

Produce pristine video quality over the lowest bitrates with Pure CPU solution

UDP, RTSP, RTMP, HTTP, HTTP Live Smooth(HLS), FTP Protocol IP Output

More stable and reliable, and scalable

Make transcode itself achieve the highest efficiency, and optimize latency transcoding.

More cost savings. Take IRD1218 for an example, it has 8 tuners, if every tuner has 38Mbps data streams and 10 programs, which makes it 300mbps Bitrate and 80 programs in total. That means you can share one IRD1218 for 4 transcoders to use.

Arrange programs to any named transcoder, so that HD programs works in one transcoder, and SD programs works in another transcoder, which makes the efficiency of the transcoder perform the best.

Except for transmitting DVB-S2/IP streams to trascoder, it can also be used for other purposes. (detecting, DVB broadcast headend)

Easy to Maintenance and Management System, Even one IRD fails, it will not lead to another transcodes stop working.
