Bicubic interpolation
Bicubic interpolation is an image processing method. If an image is enlarged beyond its
original size, not only are the four neighboring pixels analyzed to calculate the new resulting
pixel, but other nearby pixels are analyzed as well. This way, the new pixel is interpolated
based on eight neighboring pixels.
Bilinear Interpolation
Bilinear interpolation refers to an image processing method. If a picture is enlarged beyond
its original size, the resulting new image pixels are calculated based on the average between
the four neighboring pixels. The more a picture is enlarged with this method, the less sharp it
becomes.
Bit rate
Bit rate refers to the amount of data (binary digits) that is transmitted within a time unit
(generally 1 second), i.e. in bits/s. The higher the bit rate, the better the image quality.
Deinterlace
The deinterlacing process converts interlaced video files into complete frames (progressive),
since computer displays and modern televisions do not work with the interlaced system
anymore, but rather with complete frames.
Lanczos interpolation
Lanczos interpolation refers to an image enlargement method. The method was developed
according to an algorithm created by Cornelius Lanczos. This interpolation method provides
high quality and good sharpness levels. However, the actual visual resolution of the images
is not increased.
NTSC
The National Television System Committee Standard is a standard for video and TV in the
USA and Japan. NTSC has more individual frames (29.97 frames per second) than PAL, but
has fewer horizontal lines (525 lines).
PAL
The Phase Alternation Line procedure is the TV standard applicable for Europe. PAL
possesses 625 lines per screen and the film transmission speed is 25 pictures per second.
These are transmitted in the so-called line-jump procedure where a picture with all the odd
lines and then a picture with all the even lines are created. This corresponds to a half-picture
frequency of 50 Hz.
