how to use the clocked video input IP in SOPC

Did you have a look at the altera website (http://www.altera.com/products/ip/dsp/image_video_processing/m-alt-vipsuite.html) There you can download a reference design, which shows excactly what you want to do.

It's working only with the Video and Image Processing IP-core (no need for a new component).

the demo example 's input data is 8 bits width, but the itu656 interface is 10 bits,the least 2 bits are not used.

in my design , i want to use the clocked video input and clock video output, and the data 's width is 10(SDI) or 20(HD-SDI) bits, what shall i set the parameter.

i still donn't know how to set the input and output 's width to 10 or 20, because if i set to these value , the SOPC will give an error, it said the interface can only be 8 bit width.

for example, use the test pattern generator to generate the video content(color bar) and use the clocked video output to ourput the video and use the sdi interface serialize the video. the data width is a problem.

do i have to write a compent to connect the two component with different data width?

The SDI mega function accepts 20bit parallel data (sd-sdi only the first 10bits are used). This parallel data is multiplexed, that means that you have to set up the testpattern generator (and clocked video out) to serial. So you get the output for parallel (for example 10 bit) data, but the planes follow one after another. Be sure which color space you have to use.
