Linear video processing is a field of video engineering and technology, which deals with video signals that are arithmetically encoded and manipulated. Video processing is an essential component of all video systems, including cameras, broadcast, recording, display and processing systems. The GS2975ACNTE3Z is a highly integrated linear video processing solution, designed for next-generation image processing and compression systems.

Primarily targeted at consumer video applications, the GS2975ACNTE3Z offers functions such as handshaking, differential gain, cross color suppression and noise reduction. This allows the device to provide optimum image quality without necessitating a complex signal chain. The GS2975ACNTE3Z also incorporates a high-precision data slicer and encoder, to ensure that the signal delivered to the output is of the highest resolution possible.

The GS2975ACNTE3Z features a number of core processors dedicated to video processing. These include a video processor, a video line equalizer, a video signal shaper, a video motion estimator, and a video line decoder. The GS2975ACNTE3Z also includes additional hardware logic to support image capture, motion estimation, picture-in-picture, and up-scaling. Additionally, it supports a variety of video formats including HDTV, SDTV, digital video (DVI) and analog television signals.

The video processor performs all necessary signal-processing functions, including chroma adjustments, ghost elimination, color compensation, gamma correction, and white/black/purple balance. It also performs adaptive noise reduction, color noise correction and sub-pixel interpolation to alleviate interpolation errors. The video line equalizer corrects for signal to noise (S/N) errors, while the video signal shaper is used for signal gain adjustments, acting on the luminance and chrominance signal components.

The video motion estimator evaluates the motion vector of a frame from the current frame to the previous frame, in order to detect any changes in the picture. This process is used in digital video camcorders to improve the temporal resolution of the video. The video line decoder works to restore signal integrity after being captured or encoded; it analyzing signal params and signal range and applying algorithms such as block-map, 2D signal models, or motion-estimation algorithms.

In addition to the core video-processing functions, the GS2975ACNTE3Z is also capable of providing digital video picture resolution reduction, built-in mixer functions, and video oscilloscope testing capability. All these features make GS2975ACNTE3Z an ideal choice for high-performance and efficient linear video processing.
