Sample-rate conversion, sampling-frequency conversion or resampling is the process of changing the sampling rate or sampling frequency of a discrete signal to obtain a new discrete representation of the underlying continuous signal. [1] Application areas include image scaling [2] and audio/visual systems, where different sampling rates may be ...
Frame rate up-conversion (FRC) is the process of increasing the temporal resolution of a video sequence by synthesizing one or more intermediate frames between two consecutive frames. A low frame rate causes aliasing, yields abrupt motion artifacts, and degrades the video quality. Consequently, the temporal resolution is an important factor ...
The fields are captured in succession at a rate twice that of the nominal frame rate. For instance, PAL and SECAM systems have a rate of 25 frames/sec or 50 fields/sec, while the NTSC system delivers 29.97 frames/sec or 59.94 fields/sec. This process of dividing frames into half-resolution fields at double the frame rate is known as interlacing.
This rate was chosen because it could reconstruct frequencies up to 22 kHz and work with 29.97 frames per second NTSC video – as well as 25 frame/s, 30 frame/s and 24 frame/s systems. With 29.97 frame/s systems it is necessary to handle 1601.6 audio samples per frame delivering an integer number of audio samples only every fifth video frame ...
Splash PRO uses Mirillis Motion² technology for up to Full HD video interpolation. [4] DmitriRender uses GPU-oriented frame rate conversion algorithm with native DXVA support for frame interpolation. [5] Bluesky Frame Rate Converter is a DirectShow filter that can convert the frame rate using AMD Fluid Motion. [6]
Television standards conversion is the process of changing a television transmission or recording from one video system to another. Converting video between different numbers of lines, frame rates, and color models in video pictures is a complex technical problem. However, the international exchange of television programming makes standards ...
Upsampling can be synonymous with expansion, or it can describe an entire process of expansion and filtering (interpolation). [1][2][3] When upsampling is performed on a sequence of samples of a signal or other continuous function, it produces an approximation of the sequence that would have been obtained by sampling the signal at a higher rate ...
Retrieved 2017-04-10. The process of reducing a sampling rate by an integer factor is referred to as downsampling of a data sequence. We also refer to downsampling as decimation. The term decimation used for the downsampling process has been accepted and used in many textbooks and fields.
