How is packed progressive frame data stored in memory ?

Hi ,

 Only after initializing the DDR I was able to store the data in the memory.

The data format sent from the image sensor is in packed YUV422 with UYVY format.

I'm attaching the binary file of image sensor data stored in DDR2 region can somebody kindly verify.

The output format of the sensor is YUV422 packed progressive  1280 * 720p format

(Please visit the site to view this file)

I have some doubts regarding the packed progressive format data storage in memory.

 

In Technical reference manual the diagram show the top field active video area containing luminance and chrominance .

There is a note in Technical reference manual stating "Note that because progressive video only uses top-field buffers, the address offset per line of data is equal
to hofst (CnIMGOFFSET =hofst)"

What is meant by Y/C muxed and Y/C non-muxed ?

How does this affect packed progressive YUV422 data storage?

Is there any document indicating various file formats structure  related to image and video file storage ?.


 

How the progressive packed video stored in memory ?

Below is the rar file containing the binary memory image of the progressive data stored in DDR2 region of OMAP.

The frame format as seen by YUV tools

Below is the YUV TOOLS setup for examples yuv422packed_file of TI image analyzer folder
