Problem with line number and CRC insertion for SDI

Hello,

 

I am using SMPTE SDI IP in HD SDI mode with 720p mode in Kintex 7 FPGA. In order to insert Line number and CRC, I have set tx_insert_crc and tx_insert_ln signals high throughout simulation.  

But, I am seeing that LN and CRC are skipped for the first line in Rx side and it starts from second line.

Tx line number starts from 1,2,3 while Rx line numbers are 0,2,3 and so on. 

Also, rx_crc_err_a signal remains high for the first line in Rx side.

I am inserting line number before XYZ word of EAV as mentioned in data sheet.

Kindly help me fix the issue.
