Question about Panasonic PT-53TW53 53" Rear Projection HDTV-Ready Television
Just bought a Panasonic sc-pt950 home theatre that has an HDMI connection or you can use the component connections.
TV is a Hitachi HDTV with no hdmi only component connections (or s - as well). I am very new to connecting any of this but have faired ok except for...
Question 1: Should I buy a cable with one end HDMI (to attach to home theatre) with the other end the 3 prong components ( to attach to tv?) Or should I just use component connections on both? Would there be much difference? (I was that the component attachments are better than the s-video so haven't really considered this)
Question 2: Do you know if/how the remote for the Panasonic sc-pt950 works or if it does, to change tv channels. I have most of the functions all working off the home theatre remote but can't figure out how to change the tv channels??
Thank you!! Sherry
1) I believe the "3 prong" you mean the RCA A/V cable. This cable is color coded red/white/Yellow (Right Audio/Left Audio/Video). This cable is OK for regular TV but when it come to HD, the quality of the picture fall short.
But you also could mean the 3 wires component cable that color coded Green/Blue/Red. If you plug only this without the Red/White for the speaker then you will only see the picture. This component cable help make the pic a lot clearer. But I believe not as good as DVI and HDMI. More info here http://en.wikipedia.org/wiki/List_of_display_interfaces
2) Most universal remote control come with a preset of keys to emulate other remotes. You need to search for the owner manual to figure out how and what code to put to use with a certain device.
Most new Universal remotes has a learning mode too that the user can "teach" the remote to emulate that "IR signal".
Now for the "HOW". It's a little complicated. But here is my 2cents. Most basic remotes has a light in front and this light is Infra Red light. So you don't see the light but it blinks. The blinking is the data of 1 and 0 that computer uses. Most of the time the remote is in sleep mode which uses very little power. One press of the button, it switch on the remote and carry out the performance of that button. The brain of the remote figure out which button was pressed and search in it's memory for the blinking pattern and blinks the light with that pattern and then fall back to sleep.
For the pattern itself, it contain informations. It usually start with the ID of the device that suppose to receive the signal. Follow is the "flag" and then the information of the button that was pressed. Then the final signal is basically say "End" to indicate that the message end. All device within range will get this information but if the ID don't belong to it, it will ignore the entire message.
Hope what I said helped. :D
