What is Avivo

Avivo technology can improve 2D image quality. The TV card ATi Theater 550 has appeared and is now added to the display. The Radeon X1 series full range will support this technology. Avivo is an opponent of Nvidia Pure video, and technically, Avivo is stronger than PureVideo. Avivo makes the color more vivid, more meticulous, clearer, sharper. Avivo technology is for video playback in the capture, Encode, Decode, process and display five items.

Perfect High definition video playback:

AMD's ATI Avivo technology provides vibrant colors, clear images, and universal TV and monitor connections. ATI Avivo Technology has been applied to our new generation of ATI Radeon HD graphics cards. ATI Avivo HD is AMD is committed to advanced HD image processing. With the built-in Universal Video decoder (UVD) and HDMI features with multi-channel high-definition surround sound, ATI Avivo HD is able to achieve full specification HD disk playback, as well as support high quality connections to multiple HDTV and monitors.

Smooth high-definition video playback with UVD:

ATI Avivo HD technology is designed to achieve high-end high-definition video playback in home theater systems. The new UVD (Universal video decoder) can be used for hardware processing of high-definition video formats, freeing your CPU to power other applications.

Sharp videos and photos:

ATI Avivo HD enables your digital videos and photos to add color, creating sharp images, clear text, and vivid colors. ATI Avivo HD uses 10-bit display engine to optimize the color, so that the entire spectrum of the various colors are a brand-new. Achieve high quality video playback by using advanced reverse interleaving, color vibrancy enhancement, dynamic contrast, and built-in DVD upward conversion to high-definition resolution and even higher technology. Use advanced 3D comb filter and automatic gain control technology to improve the quality of video captured by your multimedia PC and PVR.

ATi Avivo Video Converter:

Accelerate your video editing and transfer to a portable video player using the new accelerated video transcoding (AVT) technology. AVT with the ATI Radeon HD 4800 series, using the GPU's parallel processing capabilities to achieve faster than real-time decoding and transcoding speed. You can convert video to H.264 and MPEG-2 formats at speeds of up to 19 times times the CPU usage. You can convert full 1080p files to H.264 and MPEG-2 formats, up to 1.8 times times faster than real time.

Analysis of Avivo Video acceleration Technology

Video codec and video capture is a pair of inseparable "twin brother", to capture a signal entered in analog mode, it must be encoded and stored in a suitable digital video format, and if the input digital signal is not in line with the user's requirements in the format, it may be decoded first, And then coded into the appropriate digital video format, the "decoding → re-coding" process is called transcoding. Because the various encoding formats are used for video storage and transmission, we have to decode them before the video is played. Avivo supports the decoding of H.264, MPEG2, MPEG4, WMV9, VC-1, DivX and WMV9 PMC at the hardware level, and supports the first five types of encodings and transcoding. For now, videos including DVDs are in the MPEG2 format, and Avivo's perfect support for MPEG2 guarantees its leading position in the field of application (PureVideo to MPEG2 encoding support is incomplete). Avivo's biggest bright spot is the support for H.264. In future High-definition video, H.264 occupies an important position, it can provide a higher compression rate than MPEG2 to reduce file size, but also at the right rate to provide higher quality video. Next-generation carriers, including Blu-ray and HD-DVD, say they will consider H.264 as a mainstream encoder. In the ointment, the Radeon X1000 series graphics card does not have complete hardware support for H.264 codec. From ATI published data, H.264 decoding of the CPU occupancy rate is quite high. However, there have been tests to show that Avivo technology can significantly reduce the CPU occupancy rate (reduced by nearly 2/3), it seems that compared with PureVideo, Avivo in the degree of support to H.264 will prevail.
