It was my question if anyone has ever seen such thumbnail.
The thumbnail is a small JPG file. PS3 doesn't show thumbnails from USB as we all know... I don't know how this could be used or it is just generated by AVCHD camcoders and Panasonic HD writer. |

Here's a small thought on the 'custom menu' issue...
Using avisynth and x264 for showing 10-40 lines of text is like using a bulldozer to dig a hole to plant a single flower. Using Java TV and BD-J should make things far-far easier. But before I start working on it - does anyone know if BD-J works if authored in AVCHD format written on a DVD or USB? I've seen a lot of BD-J games in the past, but I can't make them work now. |

Help with Palette Segment in BDMV
Is there an easy way to find the Palette Segment in a m2ts file?
I can change the color of the Interactive Graphics Stream, but I don't know what is in the color look-up table and the colors are randomly selected. I see three values for color index + one for alpha (opacity). For example I have these: Code:
11101011 10000000 10000000 (EB 80 80 - WHITE) 00010000 10000000 10000000 (10 80 80 - BLACK) 10101101 00011010 00101010 (AD 1A 2A - GREEN) 00111111 11110000 01100110 (3F F0 66 - RED) I struggle to find how to use this 8 bit Index lookup table. Thanks. *** The first byte seems to be the luminosity strenght, the second and third define the color... I'm not sure if it is in YCrCb format.. *** edit again.. It is YCrCb...

I will implement custom color for IGS in multiAVCHD using RGB->YCrCb with the following settings
Y = CA*R + (1–CA–CB)*G + CB*B R–Y = (1–CA)*R + (CA+CB–1)*G – CB*B B–Y = –CA*R + (CA+CB–1)*G + (1–CB)*B NTSC CA = 0.2568 NTSC CB = 0.0979 PAL CA = 0.1819 PAL CB = 0.0618 I decided to use NTSC and PAL CA/CB values as set by ITU 709 for full color range (0-255). I will report after I test how it works. |
