is hdmi bi-directional?

[dino d.]

hi everyone, i'm new to hdtv and have a simple question. most of the
dvd-r players that have up-sampling have no coaxial cable input. Is
this because hdmi is bidirectional? If not, how do most people use
dvd-r? In other words, how do you get the tv signal to the dvd-r if
it's not bidirectional and there is no co-ax input?

thanks,
dino

To answer your basic question; Yes, HDMI is bi-directional.

Keep in mind that this is an 'HDTV' group, and as such, High
Definition is assumed pertinent to your question. That being said;

There are only 2 cable types that carry High Definition (from
component to a TV) -- 1) HDMI and 2) Component.

In all likelihood the component is question will only upscale the DVD
signal if connected via an HDMI cable.

I think the OP was asking if video can be transfered from the TV
(tuner) to the DVD-R via the HDMI cable.
The answer to that question is, no.

But the DVD/HDD-Recorders I know of indeed have inputs both for CVBS
(composite) signals (via "coaxial cable"), S-Video and RGB via SCART.

(My DVD/HDD-Recorder also has its own built in diigital (DVB-T)
receiver.)

A DVI cable also carries hd video signals, but no audio.
