DM365 - tvout and component video simultaneously

I think by referring to 'tvout', you mean 'digital output'.

In that case, both digital and analog can be simultaneously configured if timings for both analog and digital outputs are same[vpbe user guide section 4.5.1.1, and 5.5.1.2].

Hi Nagabhushana,

I meant analog out only for tvout. I had this doubt because in the application example, given in SPRS457C(–MARCH 2009–REVISED APRIL 2010) doc, (Figures:  HD Video DAC Application Example and  SD Video Buffer Application Example), I felt like I cannot get

1. tvout(analog composite - required for auto iris signalling) and

2. component out ( or composite out through DAC)

simultaneously.

Please tell me if this is wrong or any other methods to achieve this.

Thanks

I referred to figures you mentioned. Usages described in section 6.12.2.4.1 and 6.12.2.4.2 are mutually exclusive. Later usage is more about describing you don't need external amplifier in Standard definition.

Thank you for the quick reply Nagabhushana.

So that means, are you telling, we cannot get the following 1 & 2 simultaneously??

1. tvout(analog composite - required for auto iris signalling) and

2. component out ( or composite out through DAC)

or any other methods available?

I am not aware of "auto iris signalling", please explain me that.

When we refer to COMPONENT or COMPOSITE, they are analog and mutually exclusive. Another option for user is digital output which can be used to connect digital displays such as LCD. Only digital and analog(either SD or HD output) can be configured to output simultaneously given that timing is same for both analog and digital.  

For IRIS control of the lens of a camera, we can use video analog signal ie tvout.

In my case, if I'm using tvout for that, I wont get component video, as you said they are mutually exclusive.

I feel you should use VPFE for camera control. VPFE deals with video inputs. If you see page 33 of VPFE user guide(SPRUFG8B), its clearly mentioned that VPFE is flexible enough to support requirements for iris. If you can explain what is the exact requirement, I might be able to help you how to use VPFE to achieve the requirement.

Hi tvs,

Is there any  "auto iris signalling" document available for DM365/DM368?

I need to integrate the dc auto iris lens with our camera. We are using DM365 and Aptina 5MP sensor.

What & where are the software changes required in the software side (which side) to make it work.?
