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.
For example—commonly only design and video processing is different in TV sets of different manufactures.
[citation needed] 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 (like a DVD player or set-top-box) 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 (for Standard Definition) to HD DVD/Blu-ray Disc players and set-top boxes, to displays like plasmas, DLP (both front and rear projection), LCD (both flat-panels and projectors), and LCOS/"SXRD".
