RTOS/TDA2PXEVM: Camera Capture-2d-deinterlaced DMA to generate 720x480

deepikateriar

Part Number: TDA2PXEVM

Tool/software: TI-RTOS

Hi All,

We are getting data from 4 CVBS cameras(720x480) connected to a ISL79987 Decoder to CSI2_PHY2 of TDA2PX.

Now the data received has the video data that has an even frame field followed by an odd frame field of 720x240 resolution.

To get the correct frame for processing , each ODD and EVEN frame field needs to be merged to generate 720x480 resolution frame buffer. Can anyone please suggest how to achieve this in TDA2PX.

Below is the representation of the operation which needs to be performed on captured frame field

Hi Deepika,

We do have a hardware accelerator and associated link to support De Interlacing on TDA2Px.
However, we do not have a usecase that demonstrates the use of this Link.

Can you please refer vision_sdk\links_fw\include\link_api\vpeLink.h

The field information is not provided in CSI2 protocol. Please check if there some meta-data provided by the sensor indicating field.
