In terms of video playback effect, previous NVIDIA graphics cards have been complained by users that they are not as good as ATI's. Therefore, NVIDIA decided to make significant improvements in this area. On the nv4x series of video cards, it will pay attention to
The effect of frequency playback is improved. Moreover, it will fully support the future HDTV and PVR standards. The main improvement measures are: 1. Support high-quality video playback and motion compensation functions. 2. High quality video zoom. 3. High quality video filtering technology. 4. Built in TV decoding module.
In terms of support for HDTV technology, NVIDIA claims to provide video stream conversion function on nv4x series video cards, support HDTV playback with 720p, 1080p and 480p resolution, and support high-precision multimedia technology and broadband digital TV protection protocol.
For PVR part, NVIDIA claims to integrate MPEG 1 / 2 / 4 standard encoder and decoder on chip. At the same time, it supports the decoding acceleration function of wmv9.
This news is undoubtedly a big good news for friends who like to compress DV and movies themselves, because the previous video compression is based on software, the CPU cost is very large, and the time is long. Now this part of the work can be completed by the video card chip, saving time and effort, and the CPU can also be freed from the heavy video compression. I don't know how NVIDIA company does this step.
