Editing DVD player (section)

=== Video ===
Video is another issue which continues to present the most problems. Early generations of DVD players usually outputted [[analog signal|analog]] video only, via both [[composite video]] on an RCA jack and [[S-Video]]. However, neither connector was intended to be used for [[progressive video]], and most later players sold then gained another set of connectors, [[component video]], which keeps the three components of the video, luminance and two color differentials, on fully separate wires. This video information is taken directly from the DVD itself. The three components compare well to S-Video, which uses two wires, uniting and degrading the two color signals, and composite, which uses only wire one, uniting and degrading all three signals.

The connectors are further confused by using a number of different physical connectors on different player models, RCA or [[BNC connector|BNC]], as well as using [[VGA connector|VGA]] cables in a non-standard way (VGA is normally analog [[RGB]]&mdash;a different, incompatible form of component video). Even worse, there are often two sets of component outputs, one carrying [[interlaced video]], and the other progressive, or an interlaced/progressive switch (either a physical switch or a menu setting).

In Europe (but not most other PAL areas), [[SCART]] connectors are generally used, which can carry composite and analog RGB interlaced video signals (RGB can be progressive, but not all DVD players and displays support this mode) or Y/C ([[S-Video]]), as well as analog two-channel sound and automatic 4:3 or 16:9 (widescreen) switching on a single convenient multi-wire cable. The analog RGB component signal offers video quality which is superior to S-Video and identical to [[YPbPr]] component video. However, analog RGB and S-Video signals can not be carried simultaneously, due to each using the same pins for different uses, and displays often must be manually configured as to the input signal, since no switching mode exists for S-Video. (A switching mode does exist to indicate whether composite or RGB is being used.) Some DVD players and set-top boxes offer YPbPr component video signals over the wires in the SCART connector intended for RGB, though this violates the official specification and manual configuration is again necessary. (Hypothetically, unlike RGB component, YPbPr component signals and S-Video Y/C signals could both be sent over the wire simultaneously, since they share the luminance (Y) component.)

[[HDMI]] is a digital connection for carrying high-definition video, similar to [[DVI]]. Along with video, HDMI also supports up to eight-channel digital audio. DVD players with connectors for high-definition video can [[Video scaler|upconvert]] the source to formats used for higher definition video (e.g., [[720p]], [[1080i]], [[1080p]], etc.), before outputting the signal. By no means, however, will the resulting signal be high-definition video; that is, aside from optional [[deinterlacing]], upconverting generally consists of merely scaling the video's dimensions to match that of higher resolution formats, forgoing the scaling that would normally occur in the output device.
