Other Parts Discussed in Thread: DLP4501, DLP4710, DLP3010, DLPC350
I need a video processing front end to support input from the relatively new HDMI 2 standard.
The requirements are
1) Support of 1080p signal at 60Hz
2) Support of 1080p signal at 120Hz (this is why HDMI2 is needed)
3) Ability to downscale 1080p to native resolution (1280x800)
4) Support of old-school HDMI 1 3d decoding would be nice (side-by-side 60Hz to upscaled 120Hz) but not necessary
Any decoder chip recommendations?
I know this question is not about a TI chipset but there's basically nowhere else to ask for recommendations.
Second question has to do with getting the frame index or rather which eye frame it is for a 3d video to feed that data to a ir led for syncing with shutter glasses.
The DLPC6401 Programmer's Guide has a paragraph on this but it couldn't be any more vague for me:
http://www.ti.com/lit/ug/dlpu012/dlpu012.pdf
There is a case where a 3D integrated circuit can convert some 3D signals such as convert some 3D signals into 120-Hz signals the DLPC6401 can accept. However, DLPC6401 does not automatically know which frame is for the left or right eye. The sequence for 3D has two sub-sequences, one for the left eye and one for the right eye. The user needs to connect left and right sync signal to one of the GPIO pins in DLPC6401. Please see Section 6.7.5 for more details about which pin is free to use and how to configure it.
This paragraph raises this question.
For the receiving device such as shutter glasses which is usually synced with an IR led, is the syncing (providing of the eye index) done by the video/3d processing front end chip, or one of the pins of the DLPC6401 chip provides the current eye index?
Because the paragraph says the user "needs to connect left and right sync signal to one of the DLPC pins" but doesn't say what for. The DLPC6401 doesn't need to know what eye the frame is for itself, besides resending that data via a pin to a circuit which blinks an IR led, or similar.
