4-in-1 MPEG-4 Digital TV Encoder Modulator with HDMI Input

Product Details


Key Specifications/Special Features:

EM-04 4-in-1 encoder & modulator is a digital TV encoder modulator. it can encode 4 channels of HD (SDI is optimal) low bit rate audio/video, and then receive 1 channel of DVB-C modulated signal and 1 channel of ASI signal input, then multiplex the digital TV streams into multiplexed streams which received from DVB-C or ASI, finally, output the multiplexed streams via 1 RF channel after QAM modulation, frequency conversion and signal amplification
This product is suitable for the user who adopts or purchases the superior operator's program, and you can construct the digital TV head-end platform with convenient operation, low cost and very little time


This product has the following main features:
Encoding & multiplexing:
  • Four independent channels of video/audio inputs (HDMI is standard configuration, 3G/HD SDI are option configurations)

  • Independent ASI inputs, DVB-C RF inputs (multiplexing input)

  • High quality H.264 video compression encoding

  • Video output bit rate range: 2-20Mbps (H.264)

  • Supports CBR/VBR video encoding

  • Input signal format: auto, 1920*1080P50, 1920*1080P59.94, 1920*1080P60, 1920*1080I50, 1920*1080I59.94, 1920*1080I60, 1280*720P50, 1280*720P59.94, 1280*720P60, 720*576I, 720*480I

  • Audio coding format: MPEG-1 L2, AAC (options)

  • MPEG-1 L2 audio encoding bit rate options: 64/128/192/256/384/968Kbps

  • Audio sample rate: 32KHz, 44.1KHz, 48KHz

  • System output bit rate range: no multiplexing (2-60Mbps), multiplexing (15850Kbps-51607Kbps)

  • Be capable to work under encoding and multiplexing modes, or work under encoding mode only; when the device is worked under encoding and multiplexing modes, it supports multiplexing of signals from ASI and RF input port, as well as multiplexing of 4 channels of audio/video encoding data streams; when it is worked under encoding mode, it supports  encoding of 4 channels of audio/video

  • Up to 24 output programs under multiplexing mode

  • Supports ITU-T J.83 Annex A/B/C modulation, output frequency range: 48MHz-860MHz

  • QAM modulation: 16/32/64/128/256

  • Supports PID filtering, mapping, and pass-through

  • Supports PCR auto-correction

  • RF output data rate: 4.3-7Mbaud/s

  • Supports gain fine-tune and in-band EPL balancing, EPL adjustment range: (0-10dB)

  • Self-adaptive filter circuit design ensures outstanding out-of-band rejection
