===== AV Converters =====


==== RGB (Chroma) Encoders ====
RGB (Chroma) encoders create s-video or composite video from RGB.  Most post-NES/Famicom consoles have one inside, though many (like the GameCube and PCEngine) use a dedicated encoder that cannot be separated from the machine.  The most common encoders are from Sony, the CXA series powered just about every pre-Dreamcast system.  The CXA1145 didn't offer real S-video, but the CXA1645 and CXA2075 did (see [[Micomsoft XMD-3]]).  The last chip, the CXA2075, is the best in the series but is very rare.

==== Chroma Decoders ====
Chroma decoders disassemble composite or s-video and rebuilt an RGB signal.  All TVs perform this function, and many arcade machines - particularly DVD or LD machines, to drive the RGB monitor from other signals.

==== Transcoders ====
Transcoders convert from one video format to another.  The most common use for a transcoder (for the users of this site at least) is to create component video from RGB, or vice-versa.

==== Scan-Rate Converters ====
Upscanners usually create VGA signals from TV-rate signals (31kHz+ from 15kHz).  You can also downscan, such as creating TV from VGA, but since most modern video cards offer this option it's becoming less common.

=== Upscan Units ===
Also called VGA boxes, among other things.  Micomsoft's X-RGB series are the best available upscan convertors, as they are typically the only ones that will work with RGB signals.
