thanks for replays
no they are not a lot of frequencies as i saw in the TV frequency table (in Iran)! some of them are in 618 and others are in 666.
i don't want to get channel 1 through x and then process them in my laptop!
there are so many devices here and each of them working in just one channel (for example, one of them running a learning algorithms that works with picture, so this machine just get the signals of channel 1 and then extract the frame, learn, and extract next frame, other one need voice to learn, one of them try to read adverst subtitles and so on...), some of them can not have a tv tuner card.
so something that i wanna do is to capture these signals then split them into what those devices wants, after that sending digitalized signals to those devise... they will work on each channel signal separately ...
so here is me, capturing [618, 666 + x] with one capture device, than separating them into channels separately, and then sending them on network for other devices...
︎:aquarius:︎:aquarius:︎:aquarius:︎ (analog signals) ︎:aquarius:︎:aquarius:︎:aquarius:︎... <-> (antenna) .... [capturing]....[ simulate 10 tuners and splitting it into 10 digital signals] ... broadcast it through network for other devices ...
