Dear Sir or Madam,
Hello.
Is it possible to support the output of BT.709 format in i.MX 6Dual.
(BT.709 looks like a BT.1120 with HSYNC、VSYNC、Field SYNC)
Best Regards,
Keita
Solved! Go to Solution.
Hi Keita
yes in theory i.MX6 IPU hardware can support it, since it can output B1120
and it complies with BT709, from ITU-R BT.1120 sect.1.1 Coding characteristics:
The signals to be digitized should comply with the characteristics described in
Recommendation ITU-R BT.709, Part 1.

Freescale provided community patch where HSYNC、VSYNC are already available
on pads:
Patch to Support BT656 and BT1120 Output For i.MX6 BSP
IPU1_DI0_PIN2 connected to adv7391 HSYNC pin. (option) | |
IPU1_DI0_PIN4 connected to adv7391 VSYNC pin. (option) |
For "Field SYNC" signal seems IPU microcode should be modified,
I think you can request this from author on link above.
Best regards
igor
