Need help determining channel frequencies to capture for VLC
 
I have an Aver Media video card I am using to capture video via VLC. It has three inputs-VHF, Composite, and SVHS. I need to determine what VHF frequencies and settings to use in order to view video from channels 4,8, and 13.

Are there good howto docs to accomplish this?

Google: Aver Media video card

Thanks for the reply, but I have already been searching for the answer prior to posting. The sites I have found about Avermedia have not yielded the information I need. I am looking a doc or web site that gives a listing of channel frequencies in kHZ.

You would have done very well to read the links I provided, but since you didn't, I will summarize them for you:

Today is October 6, 2009. With a few exceptions, the last analog TV broadcasting stations left the air on June 12th. So good luck finding any analog TV stations to feed your video capture card (the model of which you don't specify).

The simple fact is that, in the world of digital TV, there are no "channels" and there are no TV stations in the traditional sense. There are blocks of frequencies assigned to each TV broadcaster, and those frequency blocks are packed with as many simultaneous feeds as the operators can manage.

Unless you have a very new video capture card (you don't say), it doesn't support digital TV. And if it does, the broadcasts won't be likely to appear on channels 4, 8 and 13 -- these are known to be poor choices for digital TV (not to say that that no one is using them).

Thanks again for your reply.


I am aware analog broadcasting ceased in June. Our cable provider streams video to our cable box. Each TV in our home is tuned to a different channel to pick up a feed. We have three TVs; one is set to channel 4, another to channel 8, and the one I am working with is on channel 13. We are able to use the providers remote to view their channels once the TV is set to one of the channels I have mentioned. In my research I think I found that channel 13 is set to frequency 211.25 MHZ, or 211250 Khz. I am not getting any video via VLC, which is why I need to be sure I have the frequency, and advanced setting correct on VLC. I can view channel 13 via TVTime on my PC, so I am confident the capture card is working.

Any help would be appreciated

Again:

Google: channel frequencies

And if the capture box is working and your system set up properly, you should get a white-noise pattern from it even in the absence of a TV signal.

Are you trying to record all three at the same time? Chances are that your capture card only allows you to use one input at a time. v4lconf and other utilities to tell you more about your options. Although pretty limited since you'll need a converter box, VCR, DVD, cable box, satelite box, or other ANALOG signal to feed it. And it's probably standard definition too. ?zap to set a channel. Or just use kaffiene, mythtv, xawtv, or some of the other applications to view / set channels (although you'll only have one if you have a non-broadcast analog source). kaffiene has a few scripts / lists to scan for channels. But like I said you're only going to find one, assuming many things. Not really enough info to make a definite determination at this point.
