Hello all! I am new on this Forum! Excited!
FYI: Sorry for my poor grammar/English.

Okay, here see the picture:

See the IR area, I need your help how to make schematic for Data in and Data out by the IR but need to be same of TV/VCR/SETBOX's remotes waveform will be great. THANK YOU THANK YOU!

The data waveform will only be the same if you are transmitting exctly the same information as the TV etc expects to receive. That varies with brand and device.
Why do you wish to build something to transmit proprietary signals? Have you lost the remote?
BTW, the LEDs should have current-limiting resistors or the 74138 may be damaged.

74138 Resistors oh YES, I draw this for a sample as I did that... I want do this for IR testing which I have IR long extender for example here: http://www.monoprice.com/Product?p_...D3ceJCOdg16gErGtgyuS2tZaKPkc3-BEqgaAo3w8P8HAQ

I like to see the leds looks the same when leds moving.

Recently I just found out it might be use:

or
http://www.glolab.com/encdec/gl/ED4GP MANUAL.pdf
or
http://www.farnell.com/datasheets/56726.pdf

but I liked IR-DX8 more Data in and out and built in IR waveform.

but I like to see what your ideas?

thanks!
