h.264 AVC Encoders from Jointwave


  • Input: Hsync Vsync 16bits parallel data, YUV4:2:2
  • Output: NAL standard packets
  • GOP configuration: I, IP
  • I16x16 and I4x4 all intra prediction modes
  • Multiple inter prediction modes
  • CABAC or CAVLC entropy encoding
  • Output bit rate: 0.5Mbps to 300Mbps on FPGA platform 0.5Mbps to 1Gbps on ASIC platform
  • 1/4 sub-pixel motion estimation
  • Mode Decision in 1/4 sub-pixel to get best quality
  • Hadmard transform for intra and inter prediction
  • Deblocking filter
  • External memory: SDRAM/DDR/DDR2
  • No external memory required for Intra Profile .

Technical Advantages

  • H.264 Real time encoding
  • Excellent objective and subjective video at low bit rate (40% of MPEG2 for equal quality)
  • Small footprint
  • Low power consumption
  • Low delay
  • Supports BP, MP, HP and Special Profiles
  • Resolution from 640x480@30fps to 1920x1080@60fps, and up to 4Kx2K
  • Exceedingly fast CABAC and CAVLC module
  • Extremely high throughput is 300Mbps and 800Mbps
  • Single or multiple channels on one device
  • No external memory for I-Frame only applications
