DM8168 SD display

yuxi

There are 7 IOUT ports for the display. IOUTD~IOUTG could be used for SD display.

But In DVRRDK4.0, there is only one SD output display. Could DM8168 support 4 independent SD display on the SOC without external chip? How could I do it?

Thanks.

There is only one composite video encoder, so only one CVBS output can be generated.

The HDDAC outputs can generate component video outputs up to 1080p60 though so could be used for a second, independent SD video output, but it would be component video and not CVBS.

Thanks for your timely reply.

But in the hardware document evm816x_Schematics_RevG page43 and page9, there are 3 ports for component video output, and 4 ports(IOUTD~IOUTG) for CVBS.

If it supports only one SD display, what is the usage of IOUTD~IOUTG?

Two DACs can additionally support s-video at the same time, but there is still only one composite encoder, so only one modulated output.
