Dsp alg in progressive demo of RDK

Guru 20755 points

Hello,

In the progressive demo of rdk there is option to use of 2 algorithms in dsp: OSD,  SCD.  As I understand they are not really needed for the encoding, and are added just for demonstration of usage of these added features in the encoding process. 

Can you please verify that or elaborate on these algorithms? 

Thanks

    Hi,

    OSD  and SCD algorithms are not involved in encoding.
    They run on DSP processor as a demonstration for OnScreenDisplay and SceneChangeDetection.
    And there is a new VA link for video analytics on DSP, using is demonstrated in "multich_tristream_smartAnalytics.c" usecase.

    In McFW 2.0.0. using of OSD DSP link was demonstrated in  "multich_tristream_dsp.c" usecase.
    But that usecase is removed from 2.8.0 version.
    There are several changes in OSD link between  2.0.0. and  2.8.0. versions, and "multich_tristream_dsp.c"  doesn't work in 2.8.0.
    I also think it would be very helpfull if TI or anybody else could provide working example/usecase
    on how to use OSD DSP link in McFW 2.8.0.

    Thanks,
    Marko.
