No, the S-cable is the weak link in your plan.
Yes. HDTV signal can be used through HDMI, use the Component connections (not to be confused with composite) if your set has it, if not, then s-video and video would all be better than Coaxial cable.
It allows you to connect component cables into a HDMI connector/cable on the tv set.
Connect the HDMI out from your set-top box to the HDMI socket of your HDTV. Alternatively you can use component (red blue green) or S video PLUS a separate audio output (such as RCA or red and white) from your set-top box to your TV. In terms of picture quality, HDMI is the best, component next and S video worst.
s-Video is pretty much a dead standard. You should use it only if your tv does not have component video or HDMI.
Scart connectors are a European video and audio standard for analog video signals. They have been commonly used as links between video recorders and televisions as they provide a single wire interface between the two. The signals used in a scart connector vary but they can include composite, S-video, RGB and component video. All of them are analog signals. Most new televisions do not offer scart connectors but the signals are almost always available on alternative inputs. Composite will usually have a single yellow phono socket (RCA socket), component will have three phono sockets S-video will have a 4 pin mini-din socket for example. There are a range of scart adaptor cables that have a scart plug at one end and separate video and audio connectors at the other. Select the type that is needed and it should all work fine. To answer the question specifically, a scart to USB adaptor sounds like a video capture device for use in a computer and is not the right thing to use in a television, even if the television has USB sockets.
HDMI is by far the best. and S-Video is better than the VIDEO connection.
Volume is an old audio and music term, and its use in TV is merely carried over from radio. It only applies to the sound component, not the video component.
Monster Gamelink component video cables enable HDTV will be a good choice.
You wouls use s-video or an rca plug
You cannot convert one to the other. HDMI is digital, and has built-in Digital Rights Management (copy protection). Component is analog and has no protection. Some upper model surround receivers can 'up convert' component to HDMI, but will not allow HDMI sources to play on a TV with only component video inputs.
Component video and S-video are 2 types of connectors, although S-Video and Component connections are from TV's and DVD players quickly, in favor of HDMI connections. All new models of DVD players made after December 31, 2010 will only output Standard Definition video from the component outputs. 720p, 720i and 1080i will not be offered as output options on new models of DVD players. Note that neither of these connection types send the audio from the DVD player to the TV. You will need analog or digital audio connectors for that.
