Re: Re: Real-time video - Naresh Patel - Oct 11 8:04:29 2007



Hi Diego,

could u please provide me some good material on close caption?

Hi Aizler,

There is an example code for text overlay in code section on www.blackfin.org. 

Hi Matt,

you can implement real time video in out on BF561. coz it has a dual core and two PPI. 

Best regards,
Naresh

  To output text in the video one very easy way is to use close caption.

  2007/10/10, Nguyen Hoan Hoang <h...@aim.com>: 
    There is also an example for outputting the video have you look at it ? 
    It's under "VisualDSP 4.5\Blackfin\Examples\ADSP-BF533 EZ-Kit Lite\Video 
    Output (ASM)" directory. You can also download from the ADI site the 
    Multimedia SDK which contains example code for video in & out (both to 
    video out and LCD display).

Well I have not good documentation about closed caption.

But I can take an Image and look the blanking fields,

I could see the difference in the ancilary and esav fields between one image
with closed caption and another without closed caption, and do it.

How to do closed caption?
