ATI Avivo During capturing, ATI Avivo amplifies the source, automatically adjust its brightness and contrast. ATI Avivo implements 12-bit transform to reduce data loss during conversion; it also utilizes motion adaptive 3D comb filter, automatic color control, automatic gain control, hardware noise reduction and edge enhancement technologies for better video playback quality. In decoding, the GPU core supports hardware decoding of H.264, VC-1, WMV9, and MPEG-2 videos to lower CPU utilization (the bitstream processing/entropy decoding still requires CPU processing). ATI Avivo supports vector adaptive
de-interlacing and video scaling to reduce
jaggies, and spatial/temporal dithering, which attempts to simulate 10-bit color quality on 8-bit and 6-bit displays during process stage.
ATI Avivo HD The successor of ATI Avivo is the ATI Avivo HD, which consists of several parts: integrated 5.1 surround sound HDMI audio controller, dual integrated
HDCP encryption key for each DVI port (to reduce license costs), the Theater 200 chip for
VIVO capabilities, the
Xilleon chip for TV
overscan and
underscan correction, the Theater 200 chip as well as the originally-presented
ATI Avivo Video Converter. However, most of the important hardware decoding functions of ATI Avivo HD are provided by the accompanied
Unified Video Decoder (
UVD) and the Advanced Video Processor (AVP) which supports hardware decoding of
H.264/AVC and
VC-1 videos (and included bitstream processing/entropy decoding which was absent in last generation ATI Avivo). For
MPEG-1,
MPEG-2, and
MPEG-4/
DivX videos, motion compensation and iDCT (inverse discrete cosine transform) will be done instead. The AVP retrieves the video from memory; handles scaling, de-interlacing and
colour correction; and writes it back to memory. The AVP also uses 12-bit transform to reduce data loss during conversion, same as previous generation ATI Avivo.
HDMI supports the transfer of video together with 8-channel 96 kHz 24-bit digital audio (and optionally Dolby TrueHD and DTS-HD Master Audio streams for external decoding by AV receivers, since HDMI 1.3). Integration of an audio controller in the GPU core capable of surround sound output eliminates the need for
S/PDIF connection from
motherboard or
sound card to the video card, for synchronous video and audio output via HDMI cable. The
Radeon HD 2900 series lacked the
UVD feature, but still was given the ATI Avivo HD label.
ATI Avivo Video Converter ATI has also released a transcoder software dubbed "ATI Avivo Video Converter", which supports transcoding between H.264, VC-1,
WMV9, WMV9
PMC, MPEG-2,
MPEG-4,
DivX video formats, as well as formats used in
iPod and
PSP. Earlier versions of this software uses only the CPU for transcoding, but have been locked for exclusive use with the ATI
X1000 series of GPUs. Software modifications have made it possible to use version 1.12 of converter on a wider range of graphics adapters. The ATI Avivo Video Converter for
Windows Vista was available with the release of Catalyst 7.9 (September 2007 release, version 8.411). The ATI Avivo Video Converter with GPU transcoding acceleration is now also available for use with HD 4800 and HD 4600 series graphics cards and is included with the Catalyst 8.12 drivers. Support for Vista x64 is available via a separate download starting with Catalyst 9.6 (9-6_vista32-64_xcode). The new software is faster than Badaboom, an encoder that uses NVIDIA's
CUDA to accelerate encoding, but has a higher CPU utilization than Badaboom. One review reported visual problems with iPod and WMV playback using Catalyst version 8.12, and although concluding there was no clear winners, if forced to choose would go with the Avivo converter. ==Software support==
