How can I output a HDMI 1.4a-compatible stereoscopic signal from an OpenGL application to a 3DTV?


I have an OpenGL application that outputs stereoscopic 3D video to off-the-shelf TVs via HDMI, but it currently requires the display to support the pre-1.4a methods of manually choosing the right format (side-by-side, top-bottom etc). However, now I have a device that I need to support that ONLY supports HDMI 1.4a 3D signals, which as I understand it is some kind of packet sent to the display that tells it what format the 3D video is in. I'm using an NVIDIA Quadro 4000 and I would like to know if it's possible to output my video (or tell the video card how to) in a way that a standard 3DTV will see the correct format, similar to a 3D Blu-ray or other 1.4a-compatible device, without having to manually select a certain 3D mode. Is this possible?


Solution

  • I don't see a direct answer for the question.

    HDMI 1.4a defines meta data to describe 3D format. video_format 010 means 3D 3d_structure 0000 frame packing, 0110 top-bottom, 1000 side-by-side

    But, if the driver doesn't have an api for that, you need to change its code (assuming it's open or you have access)
