Video processing


In electronics engineering, video processing is a particular case of signal processing, in particular image processing, which often employs video filters and where the input and output signals are video files or video streams. Video processing techniques are used in television sets, VCRs, DVDs, video codecs, video players, video scalers and other devices. For example—commonly only design and video processing is different in TV sets of different manufactures.

Video processors are often combined with video scalers to create a video processor that improves the apparent definition of video signals. They perform the following tasks:
These can either be in chip form, or as a stand-alone unit to be placed between a source device and a display with less-capable processing. The most widely recognized video processor companies in the market are:
All of these companies' chips are in devices ranging from DVD upconverting players to HD DVD/Blu-ray Disc players and set-top boxes, to displays like plasmas, DLP, LCD, and LCOS/"SXRD". Their chips are also becoming more available in stand alone devices.
