Re: Details of DVPAL Codec




SMPTE 314M-1999 is the document you want.. I think I bought it for around $50USD... from the web site that Bob listed below.
It describes the contents of each DV frame for both PAL and NTSC.
When you do GetMediaSample() you'll get a single DV frame. The document describes pretty much what every byte in each frame is used for.

Hi,

Thanks a lot for that! I will take a look.

I really was wanting to know the format of the data buffer returned by GetMediaSample(). I've found a document that describes the format for some of the Codecs (Uncompressed Y CbCr Video in QuickTime Files) but it doesn't include the DV-PAL details.

Thanks a lot
All the Best

Hi All,

Where can I find details of the DV-PAL Codec?

The DV format is documented in IEC 61834. Cost is about $450. Available
from <http://www.iec.org>.


The DVCPro versions are documented in SMPTE standards. Cost about $90
for 306M-1998 and 314M-1999. Available at <http://www.smpte.org>.

More details on the various standard docs can be found on Adam Wilt's
site <http://www.adamwilt.com/DV-tech.html>.

The information is all there, but it's not a trivial job to implement it
right. The standards leave out a lot of the finer points which can make
one implementation better than another.
