HD Transmission

rbinck

The DVD/VCR combos are basically analog NTSC video unless it is an upconverting unit and has a HDMI output. But most likely you only have analog outputs. You should be aware that if you use the component video outputs (red-blue-green) for the DVD you will also need to use the audio outputs (red-white) for the DVD sound. You should also be aware that most VCR/DVD combos will not play the VCR through the component outputs and on those units you will need to use the A/V outputs (red-white-yellow) to allow both the DVD and the VCR.

are u sure? right now i only have a co-ax going from my vcr to my tv, so surely it carries analog video and audio, no?

As quoted from link I supplied:
coax cable

A digital coaxial audio connection is a wired connection that is used for transferring digital audio signals (such as PCM, Dolby Digital, and DTS) from a source device, such as CD or DVD player and an AV receiver or Surround Sound Preamp/Processor. Digital Coaxial Audio Connections use RCA-style connection plugs.


this is an RF coax:
The RF Coaxial Cable connection is used for transferring television signals (audio and video) orginating from an antenna or cable box to a Television. In addition, VCRs can also utilize this connection for both receiving and transferring television signals and for watching VHS tapes. The type of RF Coaxial Connection pictured here is the Push-on type.

yeah, i was mistaking it for an RF. sorry, the link u gave had lots fo links on it and had trouble finding everything.

i'm looking to spend $300 on an hdtv. can 1 get as large as 37" with decent enough quality? and do speakers from most flat screens not sound so great?

i was surprised to see the following Coby TFTV3925 39-Inch 1080p 60Hz for $270.

ImRizzo

Your budgeted price will not buy you anything of quality and the sound from these panels, especially in that price range will be quite disappointing.

i do have a surround sound system. i don't think the above unit has audio out jacks, so i could connect my cable box to the tv, and also the box to the surround sound receiver. the reviews for the picture quality do seem decent.

when u say low quality, are u also referring to the picture, or just the sound?

BIslander

Yes, you can connect your cable box to the TV for video and to the surround system for sound.

ImRizzo

Picture quality, keep in mind you get what you pay for.

for non-HD input, would a 25 ft coax cable produce an ok picture? i saw a comment where coax looks worse on an HD tv than regular tv.

BIslander

The bigger the screen, the worse it looks, sort of like blowing up a jpg on your computer. That will be true no matter what cable you use. A long composite run just makes it even worse.

jimlau

so an HDTV is viewable only with HD signals? i would have both HD and regular digital signals, like DVD's.

ImRizzo

HD is only receivable from an HD source DVD is not an HD source it is a SD source.

Not what I said. You can watch SD on an HD set. But,it may not look very good.

jimlau

yes, i got that. just wondering how bad a regular digital signal would look on, say, a 39" HDTV about 12 feet away. i would think it would not look worse than a non-digital tv, no?

ImRizzo

An HD display will only enhance (magnify) the poor quality of an SD signal , it will not make it better.
