'About TV and VIDEO signals'

Hi,

I have a CCD camera, and I know that I can connect the CCD camera
to the TV, but I would like have information about Video signals
and tv signals.
Anyone know where can I find information about tv and video
signals on Internet or could you tell me a good book?.
Please, I need your help with video and tv signals.
I'm interested in PAL format.

Regards,
Jose Antonio Noda

This is a PIC discussion! I think!

Couldn't a properly clocked PIC generate black/white video?  A buffered
5:1 voltage divider on a port output could theoretically drive a composite
video jack, like on a VCR or monitor?

As for a book, I highly recommend Tomasi's communications book.  I forget
the name exactly, but I could dig it up if necessary.

Right you are! But if I can clock a TV's ass with a PIC, I will. I am
also interested in a possible PIC/CCD thread, so all you video experts
out there - go for it! :)

David Tait's web page (as I recall) has details of a 16C84 application
to generate a video clock display using a 4-bit DAC.

Wayne Tomasi usually publishes via Prentice-Hall
As well, hit the ol' library and scan the index issues of Radio-Electroincs
from the late 80's - there were tons of articles on tv projects that
explained the signalling formats.
Good Luck,

About four years ago there was a design contest winner in Ciarcia's
Circuit Cellar Ink that used a '54 as a one IC video wind speed and
direction gage. It generated B/W NTSC video with block characters that
showed current wind speed, average wind speed, and direction. I don't
know if code was available or not. I know I was truly impressed with
that much being done - all in less than 512 bytes! This article is what
got me interested in PICs in the first place. Wish I could remember the
author.

Hi,

I see that you know a little about PIC microcontrollers,
I asked about tv and video signals, because I have some schematics
and information about Universal Decoder using PIC16C54.
I know a little about tv signals, but I don't know if a PIC microcontroller
could generate black/white video.
I'm asking these questions.

Hey!!!!!!

I know that video and tv signals in the pic mailing list,
is a little off topic, but I have schematics about a Universal Decoder,
using PIC16C54, a satellite decoder.ok?.
I think this is a PIC discussion, but I have see some schematics of video
with PIC, if this is a PIC discussion, tv signals with pic is intersting.

Hi,

Thanks for your help, I will scan the index of Radio-Electronics.
Do you know the web?.

I have the code for this, but I need the article or at least the circuit,
could
anyone send it to me, or make it avaible on the net? I can send the code.

Octavio
