today i changed the code,modified the SDI_IF as following:

.tx_ln({tx_ln,tx_ln}),

);

then the problem was solved, the line number inserted into the right position.

but the SDI MegaCore Function User Guide v9.0 page 3-27 said tx_ln signal when HD-SDI: bits 21:11 11'd0;bits10:0 LN. I suggest Altera should change this line to HD-SDI: bits 21:11 LN;bits10:0 LN.

other defination i am testing .......
