| 09:59 | Bertl | morning everyone!
|
| 10:42 | guesst | morning, sebastial told me you know what are the limitations of the hdmi on the zedboard
|
| 10:42 | guesst | is it yuv or 422 or both?
|
| 10:49 | Bertl | from the datasheet and the zedboard schematic, we are limited to YCrCb in up to 10bit
|
| 10:49 | Bertl | but I figured that we can enable a mode, which is basically RGB-422 by setting the color conversion to pass through
|
| 10:50 | Bertl | or more precisely RGB-242
|
| 10:50 | Bertl | i.e. the green value can be set for every pixel, the red and blue apply for two pixels and get interpolated
|
| 10:51 | Bertl | but we can't do 444 in any color scheme, because the zedboard design made an unfortunate decision with picking data 8 to 23
|
| 10:56 | guesst | i think rgb 422 is not worth it.. ycbcr 422 should be a better option (in terms of consequent data compression)
|
| 11:18 | Bertl | maybe, the thing is, the RGB-242 fits the bayer pattern, so it might be simple yet more accurate in positioning ... but we'll see, RGB -> YCrCb isn't that hard to do

| 18:54 | troy_s | guesst: It isn't YUV. That is analog.
|
| 18:55 | troy_s | guesst: And YCbCr 422 is an alternate model. RGB can be transformed with to YCbCr with no loss assuming sufficient depth.
|
| 19:04 | troy_s | (And RGB would provide a display referred linear, which is never a bad option. YCbCr is TRC applied (Y'Cb'Cr'))

| 19:28 | guesst | i prefer raw :)
|
| 20:34 | troy_s | guesst: You realize that RGB 422 _is_ effectively raw? It is a meaningless term, but more on point, your particular query was related to HDMI. I respect that your candor has shifted from outright trolling, however.
|
| 20:34 | troy_s | FergusL: On that point, did you manage VNG? Interested in the chroma citing.
