2-ch H.264 HD Encoder combines 2 functions:

  • MPEG-4 / MPEG-2 encoder with SDI, CVBS, HDMI inputs;
  • 2 programs transcoder in the transport stream.

Encoder or transcoder function is switched by the control program.
Each 2-ch H.264 HD Encoder can generate two streams of the same program to ASI and IP outputs. Additional stream can have a maximum resolution of 720x576i. The maximum resolution of image in the main stream is 1920x1080i. It is usable for broadcasting a program in HD and SD standards. The most important feature of 2-ch H.264 HD Encoder is ability to work with low signal delay up to 100 ms (low delay mode (optional)).


  • Transcoding of an SD/HD program
  • The possibility of 2 audio channels transferring in the first coder
  • Supports OTA, EPG, DVCrypt CAS 3000/10000/100000 subscribers in transcoder
  • Two SDI / two CVBS / two HDMI inputs
  • Software switch input signals
  • Maximum output bitrate of 15 Mbit/s per channel
  • IP outputs. Five adresses. RTP, UDP protocols, multicast, unicast
  • Overlaying titles on the signal
  • High Profile and Main Profile modes
  • Encoding: MPEG-2 HP@HL, MP@HL , MP@ML; MPEG-4 H.264 HP@L4, MP@L3
  • Transcoding: MPEG2 > MPEG4, MPEG2 > MPEG2, MPEG4 > MPEG2, MPEG4 > MPEG4
  • Selectable MPEG-2 SD or H.264 SD/HD real-time video encoding
  • User selectable resolution and bitrate
  • The ability to upgrade via Ethernet
  • The ability to turn the test signal with the sound
