The ADV7441A has the Betacam bit (User Map, Address 0x01).
But we can not find it in the HW/SW manuals of the ADV7842.
If we want to realize the same function, we have to use manual gain control function?
The 'Beta bit' changes the voltage levels a bit for beta inputs. The ADV7842 is a newer part that handles this input slightly differently. It should handle the input just fine. Try the standard scripts to see if there are any problems.
Thank you for your reply.
But we can not understand you mentioned.
Could you explain it in concrete terms ?
And what is the standard scripts ?
The ADV7842 scripts can be found here
Advantiv™ EVAL-ADV7842-7511 Video Evaluation Board
in the AVES3_Folder
You mean "ADV7842-VER.5.9c_AVEB" ?
The same script process both Betacam input and SMPTE input ?
What is the different in the process between Betacam input and SMPTE input ?
