Live Encoder/Transcoder
MediaStream Live Encoder is professional software to encode and transcode live input DVB- and SDI-streams into multi-output multi-profile DVB- or HLS-stream.
Software works under Microsoft Windows and Intel Processors of last generations with graphical core Intel QuickSync.
Key features
- Full support of SCTE-104@SDI, SCTE-104 over IP/GPI/SNMP and SCTE-35 on input
- SD- and HD-input, up- and down-scale, de-interlacing, short-time delay
- Multi-profile outputs contain splicing-compatible DVB- and HLS-streams, strict VBV-control is performed and SCTE-35 messages are embedded.
- Automatic scheduled and externally-controlled regionalization (ad insertion, blackouts, animated banners, creeping lines, etc.) by SCTE104-SDI/OverIP/OverSNMP/OverGPI or by DTMF-tones.
Technical specification
-
Inputs:
- SD/HD-SDI from StreamLabs, Blackmagic, Dektec, ATS
-
MPEG2/H264 and MPEG1 audio/AAC from DVB-IP Multicast/Unicast UDP/RTP with FEC, DVB-ASI/S/S2/T/T2/C/C2, HTTP, HLS
-
Output, multi-profile: DVB-IP Multicast/Unicast UDP/RTP with FEC, DVB-ASI, HTTP, HLS.
- Compression formats:
- video MPEG-2 (ISO 13818-2)
- video H.264 (ISO/IEC 14496-10)
- audio MPEG-1 (ISO 11172-3, Layer I, II, III)

- teletext SMPTE-2031 и OP-47
-
SCTE-104 in SDI, SCTE104-over-IP, SCTE104-over-SNMP, SCTE104-over-GPI
-
Regionalization features: see features of MediaStream Regionalization and insertion.
- Other features:
- strict VBV-control and splice-compatibility (in DVB) and stitch-compatibility (in HLS) of output stream
- All output streams are conformant to TR 101 290 and VBV-model for both MPEG2/H264.
- Input stream BISS-descrambling.
- Video signal upscale and downscale.
- Output stream short-time (up to 30 seconds) per-profile delay
- Active heartbeat stream UDP-IP/RS-232, reliability statistics: 99,999% uptime.
- SNMP state control
- Configuring: manually, conf-files
Notes and requirements
To capture SDI, a Dektec, Blackmagic, ATS or StreamLabs interface is required.
To output DVB-IP streams, Intel chipset-based NICs are strongly recommended.
Compression requires Intel graphic core QuickSync (for example, processors i7-7567u, i5-7260u, Xeon E3-12x5 v5/v6, E3-15x5 v5).
Approximate resources consumption: in complicated scenarios, one server is capable to (re)encode up to 4 full-HD services and up to 15 SD-services into h264, and dozens of SD-channels into MPEG-2.
Licensing
One license allows processing of one service/program if another not pointed. One year SLA included. Licenses for redundant processing of same service are discounted by 50%
