Hello
[System] NTSC ⇒ Decoder ⇒ CX3 ⇒ PC
The active pixels output by the Decoder are as follows.
- H-Active: 1440
- V-Active: 240
They are thinking that H-Active contains two lines of data when importing interlace,
Question) Regarding the MIPI capture settings (Image Sensor Configuration screen) on the CX3, is it possible to import as 720x480 by doing as following?
H-Active : 720
V-Active: 480
Or, the MIPI side sets the capture as 1440 × 240, Is the setting of the descriptor on the UVC side 720x480?
MIPI side
H-Active: 1440
V-Active: 240
UVC side descriptor setting
720 × 480
Best Regards
Mac

Hello,
This question is very similar to Re: FX3 SD video encoder
In case you would like to use Interace, you need to set "Interlace Flags" in "Class specific Uncompressed VS format descriptor" appropriately.
By default of AN75779, "Interlace Flags" is 0x00 that stands for Progressing scan. Change this field what the customer wants.
The meaning of this Field can confirm by reading "USB_Video_Payload_Frame_Based_1.1 or 1.5.pdf" and please check the offset 25 'bmInterlaceFlags' that is Specifies interlace information.
Best regards,
Hirotaka Takayama
