PVQ-RD,short for Picture Video Quality-Rating Database, is an application field of media science that studies the impacts that temporal resolution, temporal effects, compression and other artifacts have on the perceived video/picture quality. It can also help in assessing the effects that compression artifacts have on the objective quality.The application field of PVQ-RD works by creating video or picture samples from pre-made databases.These samples are then used to create a rating system or database for assessing different qualities of the video or picture.

The application field of PVQ-RD is divided into two main areas: the visual quality rating and the objective (non-visual) quality rating. The Visual quality ratings are divided into the categories of Macroblocking, Sampling, Blurring and JPEG artifacts. Macroblocking is rated on a scale from 0-10,Sampling ranges from 0-25, and Blurring ranges from 0-40. For JPEG artifacts, the PVQ-RD uses a range of 0-70.For Objective (non-visual) quality ratings, the PVQ-RD uses a range of 0-100.

The application field of PVQ-RD uses several algorithms to assess the perceived quality of video or pictures.These algorithms include image processing techniques such as temporal resolution, temporal effects, information entropy, noise estimation, edge directionality and features extraction.These algorithms are used to analyze the video or picture and then compare it to the pre-made database, which is then used to assign the video or picture a rating.

The working principle of PVQ-RD is to analyze the video or picture, measure the quality of it, and compare it to the data stored in the database, which is then used to assign it a rating. The rating is then used to compare the quality of the video or picture to other videos or pictures, which are then used to determine the overall quality of the video or picture.

The PVQ-RD application field has a variety of applications in the media industry, such as video compression, broadcast technology, and streaming video. It can also be used to determine the effectiveness of video compression routines, as well as to measure the performance of video streaming services. In addition, the PVQ-RD can help in determining the effectiveness of video codecs, such as H.264, H.265, and VP8, and can assess the effects that transcode artifacts have on video quality.

In conclusion, PVQ-RD is an important application field of media science, as it helps assess the perceived video/picture quality in comparison with the objective (non-visual) quality. It can also aid in the analysis of video compression and streaming performance, as well as determining the effectiveness of video codecs. With PVQ-RD, video producers and broadcasters can gain a better understanding of the overall quality of their video and audio content.
