H264 影像壓縮 for Texas Instruments DSPs,General Purpose Processors,PC and FPGA (VHDL IPs)
ATEME delivers H.264/MPEG4-AVC technologies for end-to-end streaming solutions.
Encoders, decoders and streaming IP integrated with 3rd party DRM has been demonstrated at IBC (September 2004, Amsterdam). Our technology is available and already adopted by customers, in Broadcast, Broadband and Corporate markets, in live SD main profile encoders and in IP Set-Top Boxes for H.264 DSP decoder.

Our encoders/decoders strictly follow ISO/IEC 14496-10 standard, implementing all tools for the very best video quality.
Benchs achieved by independent experts show ATEME's solutions as the fastest and highest quality solutions.

H.264 technology overview

H.264 / MPEG-4 Advanced Video Coding / MPEG-4 ISO 14496 part 10 boasts high quality for low bitrate and overcomes the bandwidth limitation while addressing the needs for high quality video.
This new compression standard features enhanced compression performance while providing a video representation which addresses “conversational” (video telephony) and “non-conversational” (storage, broadcast or streaming).

This standard is declined in 4 profiles:

  • Baseline
  • Main
  • Extended
  • High - coming soon

The main changes compared to MPEG-4 (part 2) are:

  • Integer transform
  • Context Adaptive Coding (CAVLC, CABAC)
  • Enhancement of every steps
  • More processing power for an enhanced quality

Encoding principle is the following:

  • Multiple reference frames are used for motion compensation step.
  • Integer transform prevents mismatch between encoder and decoder.
  • Quantization is done with Non constant step increment.
  • Context modeling (Context adaptive coding) provides conditional probability of the coding words.
  • Deblocking filter allows artifacts removal on reference frames.
