hi, Daixiwen or other gurus :

The VIP example seems to provide the way of using "Video in "interface of my development board(NEEK),I want to send the data of CCTC CCD (NTSC Video) to ethernet,so I create my SOPC system this way :

transmit :

clocked video input->SGDMA->sdram->SGDMA->TSE_MAC(build-in FIFO_tx) to ethernet

(maybe "->SGDMA->sdram->SGDMA"can be deleted,because both "clocked video input"and "TSE_MAC(build-in FIFO_tx)" support ST transmition)

receive:

TSE_MAC(build-in FIFO_rx) ->SGDMA->SDRAM

is the data flow given above right?

assume it is right,I have another confusion:

the SOPC component "clocked video input"seems to add something like head packet into video signals,so the video signals transmitted to ethernet are not clean,what I can do to resolve this problem,do it on pc?

is there another SOPC component which can replace "clocked video input",and output clean video signals , or I should write it myself,and how to do it?

I am very urgent about this project~

can you repaly me as soon as possible~

thanks a lot
