However it has dawned upon both companies that video quality on the PC would need improvement as well and the current APIs provided by both companies have not seen many improvements over a few generations of GPUs.

Features

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
