Video in to axi stream and VTC

Jump to solution

hello, sir

In my project I use video in to axi stream IP to connect my cmos sensor. but my sensor recieve port only has vs and "de" signal , no hs signal, may be hs signal is necessary for the video in to axi strean or VTC IPs? can i generate the hs signal use de in ? the flow pictures in video in stream in UG show me that SOF of pix line is generated from de signal's rise edge , Now can I get the rise edge of "de" signal in, and use it as my hs aignal input to connect the video in to axi stream or VTC IPs?if the methed is feasible, how many *clks of my "hs" width is safty,and how many *clks it before my of "de" signal?

Hi @huyongwei 

 

I suggest you to ganerate sof, eof, sol and eof by using VS and DE.

It's suitable way to resolve your issue without VTC IP.

Also when doing the conversion here are a few resources/examples of native mode:

It may help you to simulate or run a design with an ILA to get a waveform so that you can match native mode to your stream as @watari has suggested.
