Hello,
                        While setting the screen format to PAL or NTSC using
directfb, it says "not supported" but my hardware supports. Can anyone
please help me on this issue. Is there anything i have to initialize or
modify prior to setting the screen format?

here is the error log:
(!) em86_check_encoder(0) signal not supported: PAL
(!) SMP863x: encoder config failed flags 8
SetEncoderConfiguration(0) failed!

Adding the code for your reference:

DFBScreenEncoderConfig enc_cfg;
DFBScreenOutputConfig out_cfg;
DFBScreenOutputSignals signal = DSOS_PAL;
        enc_cfg.flags = (DFBScreenEncoderConfigFlags)(DSECONF_OUT_SIGNALS |
DSECONF_DELAYED_CONFIG);
        enc_cfg.out_signals = signal;
        enc_cfg.delayed_config = true;
        if (GfxScreen->SetEncoderConfiguration(GfxScreen, 0, &enc_cfg) !=
DFB_OK)
        {
            dprintf("SetEncoderConfiguration(0) failed!\n");
            component = false;
            analog = false;
        }
        else
        {
            out_cfg.flags = (DFBScreenOutputConfigFlags)(DSOCONF_SIGNALS |
DSOCONF_DELAYED_CONFIG);
            out_cfg.out_signals = signal;
            out_cfg.delayed_config = component || analog;
            if (GfxScreen->SetOutputConfiguration(GfxScreen,  0, &out_cfg)
!= DFB_OK)
            {
                dprintf("SetOutputConfiguration(0) failed!\n");
                component = false;
                analog = false;
            }
        }
