ATI Avivo™ HD Technology

The AMD Radeon™ HD 3870 GPU features ATI Avivo™ HD technology with advanced audio, video processing, display and connectivity capabilities for high definition entertainment solutions

  1. Introducing a breakthrough for the playback of Blu-ray™ and HD DVD discs
  2. UVD (Unified Video Decoder) is a new HD video processor that provides hardware decoding of Blu-ray and HD DVD
  3. UVD is designed to enable a cool, quiet media PC with low GPU and CPU power requirements
  4. ATI Avivo™ HD technology includes fully integrated HD audio capabilities and supports playback of multi-channel (5.1) audio streams.  When combined with the integrated HDCP copy protection, ATI Avivo HD enables a one-cable HDMI™ connectivity solution to high definition home theaters

ATI Unified Video Decoder Technology

Connect your PC to your home theater and start watching HD content from your computer using new ATI Radeon™ HD 3800 series graphics cards. The ATI Radeon™ HD 3800 Series is designed to decode and playback Blu-ray and HD DVD formats using dedicated hardware within the GPU. This technology, known as UVD or Unified Video Decoding, is part of ATI Avivo™ HD, the new collection of technologies that are designed to improve the visual and connectivity capabilities of ATI Radeon™ HD 3800 Series GPUs. The new and improved UVD offloads the intensive process of HD video decoding and playback from the CPU while improving the visual quality. This means you can get smooth, high quality HD video playback at full HD 1080p from most entry level PCs, or free up the CPU for other tasks while you enjoy the movie. And with HDCP* built into the GPU, the new cards easily enable playback of HDCP protected content.
