- Greetings all,
-
- I am looking for pointers in converting digital YUV data to standard RGB
- format. Now, I believe there are multiple ways by which YUV data may be
- represented. For example, the pbmplus toolkit has a program that converts
- Abekas YUV bytes into a portable pixmap but I am not sure whether this is
- the same YUV format used by the Sun VideoPix board which uses the SAA9051
- Digital Decoder chip to convert composite video into 4:1:1 YUV data. By
- 4:1:1 format I mean for example 8-bit data where there are 8 bits of Y for
- every 2 bits of U and V.
-
- So, my question is: does there exist a standard way of converting the YUV
- data ( once I have extracted the Y, U and V components ) to RGB regardless
- of the format in which the YUV information was actually represented?
-
- Many thanks

- PS - I'll post a summary.
