this is a funny hobby....am pretty advanced on many topics, neophyte on others. can someone help with what video switching is and why it is needed? I assume that it entails routing a video signal in some fashion, but, in the case of a dvd, for example, can one not just go directly to the tv, thereby eliminating such a "switching" need?thanks
Follow Ups:
For years I sent all of my signals directly to the monitor. However last year I purchased a unit with video switching. Much easier to use for the rest of the folks who do not know how you have your system routed. You press dvd on your pre-amps remote and the video is switched to the picture output of the dvd and sound is played to thru the speaker. Usually it is a seemless transition. Do you have to have it? No. It is just easier to use. No switching inputs on your tv and then on your reciever or preamp. But the most important thing to condsider is signal degradation. Only the better receivers, processors, and video switchers can switch video signals without degrading the signals. You may want to experiment and to see if you are trading ease of use for picture quality.
... included in some processors to allow for different inputs - e.g. a video recorder, a DVD player and cable. The audio & video switch together if all are routed via the processor. A nice convenient option, especially when remote controlled.John
