ADV7610 Input Signal indenfity Issue

I used ADV7610BBCZ-P as HDMI Video signal receiver on board,  when the input signal is generated by a signal generator, all is OK. But when I test it using other devices such as DV(Sony and Panasonic), satellite boxes,  most of them can't be identified by ADV7610, but all of them can be identified and displayed on TV.

By checking the register of ADV7610, I find  TMDS_CLK_A_RAW,IO, Address 0x6A[4] =0 that means No TMDS clock detected on PortA.

Could you give some advise on it?
