What is the meaning of DVD Component In for a color tv and what will happen if a TV don't have that?

Answer 1

Component video signals are in fact three separate signals. One carries brightness information and the other two carry color information. It is the format used in broadcast environemnts and provides the best video quality. Please note that component is NOT an RGB signal, as used in VGA signals. Even if a DVD player has component output, it will also support composite signals, which use a single signal cable. The connection will be on an RCA or phono connector or perhaps on a scart connector in Europe. Most players will also have an S-video output as well as composite. Check that the television has either a composite input or an S-video input and the player should work without any problem. S-video is a better quality signal than composite and should be used if there is a choice between the two. All of the signals mentioned so far are analog. Most modern televisions and DVD players now have HDMI or DVI links. Although these are both interfaces designed to support high definition, they also operate at standard definitions. HDMI carries sound on the same cable and therefore provides a convenient and high quality interface.
